Solar energy is the radiation from the Sun capable of producing heat, causing chemical reactions, or generating electricity. The total amount of solar energy received on Earth is vastly more than the world's current and anticipated energy requirements. If suitably harnessed, solar energy has the potential to satisfy all future energy needs.

What are the common uses of solar energy?

Solar energy is commonly used for solar water heaters and house heating. The heat from solar ponds enables the production of chemicals, food, textiles, warm greenhouses, swimming pools, and livestock buildings. Cooking and providing a power source for electronic devices can also be achieved by using solar energy.

The most common devices used to collect solar energy and convert it to thermal energy are flat-plate collectors. Another method of thermal energy conversion is found in solar ponds, which are bodies of salt water designed to collect and store solar energy. Solar radiation may also be converted directly into electricity by solar cells, or photovoltaic cells, or harnessed to cook food in specially designed solar ovens, which typically concentrate sunlight from over a wide area to a central point.

solar energy , radiation from the Sun capable of producing heat , causing chemical reactions , or generating electricity . The total amount of solar energy incident on Earth is vastly in excess of the world’s current and anticipated energy requirements. If suitably harnessed, this highly diffused source has the potential to satisfy all future energy needs. In the 21st century solar energy has become increasingly attractive as a renewable energy source because of its inexhaustible supply and its nonpolluting character, in stark contrast to the finite fossil fuels coal , petroleum , and natural gas . See also solar power .

• Geothermal power
• Hydroelectric power
• Solar power
• Tidal power

The Sun is an extremely powerful energy source, and sunlight is by far the largest source of energy received by Earth , but its intensity at Earth’s surface is actually quite low . This is essentially because of the enormous radial spreading of radiation from the distant Sun. A relatively minor additional loss is due to Earth’s atmosphere and clouds , which absorb or scatter as much as 54 percent of the incoming sunlight. The sunlight that reaches the ground consists of nearly 50 percent visible light , 45 percent infrared radiation , and smaller amounts of ultraviolet and other forms of electromagnetic radiation .

Solar energy drives and affects countless natural processes on Earth. For example, photosynthesis by plants , algae , and cyanobacteria relies on energy from the Sun, and it is nearly impossible to overstate the importance of that process in the maintenance of life on Earth. If photosynthesis ceased , there would soon be little food or other organic matter on Earth. Most organisms would disappear, and in time Earth’s atmosphere would become nearly devoid of gaseous oxygen . Solar energy is also essential for the evaporation of water in the water cycle , land and water temperatures, and the formation of wind , all of which are major factors in the climate patterns that shape life on Earth.

The potential for solar energy to be harnessed as solar power is enormous, since about 200,000 times the world’s total daily electric-generating capacity is received by Earth every day in the form of solar energy. Unfortunately, though solar energy itself is free, the high cost of its collection, conversion, and storage still limits its exploitation in many places. Solar radiation can be converted either into thermal energy (heat) or into electrical energy , though the former is easier to accomplish.

Solar energy has long been used directly as a source of thermal energy. Beginning in the 20th century, technological advances have increased the number of uses and applications of the Sun’s thermal energy and opened the doors for the generation of solar power.

Among the most common devices used to capture solar energy and convert it to thermal energy are flat-plate collectors , which are used for solar heating applications. Because the intensity of solar radiation at Earth’s surface is so low, these collectors must be large in area. Even in sunny parts of the world’s temperate regions, for instance, a collector must have a surface area of about 40 square meters (430 square feet) to gather enough energy to serve the energy needs of one person.

The most widely used flat-plate collectors consist of a blackened metal plate, covered with one or two sheets of glass, that is heated by the sunlight falling on it. This heat is then transferred to air or water , called carrier fluids, that flow past the back of the plate. The heat may be used directly, or it may be transferred to another medium for storage. Flat-plate collectors are commonly used for solar water heaters and house heating. The storage of heat for use at night or on cloudy days is commonly accomplished by using insulated tanks to store the water heated during sunny periods. Such a system can supply a home with hot water drawn from the storage tank, or, with the warmed water flowing through tubes in floors and ceilings, it can provide space heating. Flat-plate collectors typically heat carrier fluids to temperatures ranging from 66 to 93 °C (150 to 200 °F). The efficiency of such collectors (i.e., the proportion of the energy received that they convert into usable energy) ranges from 20 to 80 percent, depending on the design of the collector.

Another method of thermal energy conversion is found in solar ponds, which are bodies of salt water designed to collect and store solar energy. The heat extracted from such ponds enables the production of chemicals, food, textiles, and other industrial products and can also be used to warm greenhouses , swimming pools, and livestock buildings. Solar ponds are sometimes used to produce electricity through the use of the organic Rankine cycle engine, a relatively efficient and economical means of solar energy conversion , which is especially useful in remote locations. Solar ponds are fairly expensive to install and maintain and are generally limited to warm rural areas.

On a smaller scale, the Sun’s energy can also be harnessed to cook food in specially designed solar ovens . Solar ovens typically concentrate sunlight from over a wide area to a central point, where a black-surfaced vessel converts the sunlight into heat. The ovens are typically portable and require no other fuel inputs.

51 Uses of Solar Energy

Our sun is the source of all life on Earth, making solar energy useful to us in many different ways. 

The sun creates two main types of energy — light and heat — that we can harness for numerous activities. These range from prompting photosynthesis in plants to creating electricity with photovoltaic (PV) cells to heating water and food. 

So, what are some uses of solar energy? Let’s explore 51 common uses of sunlight in our daily lives.

Find out if you can save with your personalized free estimate.

Home systems.

A rooftop solar installation can provide enough energy to power your home’s electricity and HVAC needs.

1. Solar Electricity

This solar energy application has gained a lot of momentum in recent years. 

As solar panel costs decline and more people become aware of solar energy’s financial and environmental benefits , solar electricity is becoming increasingly accessible. While it’s still a tiny percentage of the electricity generated in the U.S. ( 2.8% as of 2021 ), solar electricity is growing rapidly.

Technicians usually install a distributed solar PV system on the rooftops of homes or businesses. These solar power systems generate electricity to offset the property owner’s usage and send any excess production to the electric grid.

2. Solar Batteries

A solar battery can connect to your solar power system. This setup lets you use solar after sundown and provides backup power during emergencies. Some homeowners may choose go as close to off-grid as possible with a solar home power system , but whether this works for you depends on several factors:

• How much energy you use daily
• The amount of sunlight in your area
• The efficiency of your panels 
• Your battery’s storage capacity 

3. Solar Generators 

A solar generator typically refers to a combination of portable solar panels, a battery, a battery charger and an inverter. These all make up one device — the generator. With it, you can absorb solar energy, then store and distribute it when needed. 

Solar generators are quite common on camping and boating trips. They also prove incredibly useful in emergency situations when you need backup power, like during a wide-scale, long-term power outage. 

What’s more, a large generator (around 20 KW of storage capacity) can power an entire house for two to eight hours. But this depends on how much energy your home uses in terms of lighting, appliances and more.

4. Solar Ventilation

Solar ventilation solutions such as solar attic fans can reduce the burden on your HVAC by helping cool your home during the summer. This may be a good option if you can’t install a solar PV system that offsets your home’s entire electricity use. One innovative product is the Solatube solar attic fan .

Solar ventilation technologies also apply to commercial and industrial use applications. These technologies can preheat a building’s air in cold climates, which reduces energy costs.

5. & 6. Solar Water Heating

Homeowners can also use solar energy to power their water heaters. Two types of solar water heating systems exist: 

• Active solar water heater systems
• Passive solar water heater systems

5. Active Solar Water Heater Systems

Active solar water heaters use mechanical circulating pumps to move fluids between your rooftop solar panels and storage tank. In turn, these heaters have two different types:

• In direct circulation systems , a pump moves regular water into your house through solar collectors. Because the water can freeze, direct circulation systems work best in climates that rarely see freezing temperatures.
• Indirect circulation systems circulate nonfreezing liquids through solar collectors to a heat exchanger. From there, the energy transfers to water that circulates into your house. Climates with freezing temperatures can rely on indirect circulation systems. 

6. Passive Solar Water Heater Systems

Unlike active solar water heater systems, passive systems lack mechanical pumps. Instead, they have simple physics to thank because heat naturally rises. Unsurprisingly, this makes them much cheaper (albeit less efficient) than their active counterparts.

Passive solar water heaters also have two basic types:

• Integral collector storage systems have a solar collector integrated directly into their water tanks, which allows the sun to heat the tank. These systems work well in homes with significant hot water needs and in climates where freezes are rare.
• In thermosiphon systems , the solar collector sits lower than the storage tank, which allows the heated water to rise into the tank. Installing thermosiphon systems is slightly more complicated because they’re usually located on the roof.

7. & 8. Solar House Heating

Typical uses of solar space heating systems include powering radiant floors or pairing with a hot water or hot air system to heat homes. 

7. Hot Water Solar Systems

Hot water solar systems use solar collectors to heat water (or another fluid, such as antifreeze). Circulating pumps move the water through the collector and into either a storage tank for later use or a heat exchanger to provide immediate warmth.

Liquid-based solar systems are complex, large-scale systems, so industries more commonly use them for commercial applications. However, they’re a home heating option.

8. Hot Air Solar Systems

Hot air solar systems work by circulating air that the sun has heated — such as by striking a wall or roof — throughout your home. 

Technicians typically design homes that rely on these systems with siding or roofing materials that have excellent heat absorption properties. The systems also often use a circulating fan to distribute the heated air, which is where solar power comes in. 

9. Solar-Powered Pumps

Some of the heating systems above rely on a pump to circulate water. Because your home’s electricity powers these pumps, they of course consume energy. And that’s energy you hoped to save by installing a solar-powered system in the first place.

To avoid this problem and save even more energy, you can install a solar-powered pump instead. Installing a battery means you can run your circulating pumps 24/7, regardless of sunlight.

10. Solar Heating for Your Swimming Pool

Another solar energy application, especially in the southern and southwestern U.S., is heating swimming pools. The systems circulate water to a collector, where sunlight heats it. The system then pumps the heated water back into the pool.

With costs between $2,500 and $4,000 and a payback period of one to seven years , the U.S. Department of Energy says that “solar pool heating is the most cost-effective use of solar energy in many climates.”

11. Solar Heating for Your Hot Tub

Like with swimming pools, solar hot tubs work by using solar collectors. 

You may be surprised to hear that solar energy can provide enough power to heat a hot tub. However, solar vacuum tubes have become so efficient that they can actually overheat your tub in the summer! To avoid this, homeowners in warmer climates often opt for flat plate panels — they get the job done without generating too much heat.

Of course, you may still need an auxiliary heater after sundown, so we recommend having your existing heater and solar heater work in tandem.

Solar Lighting

Solar can power just about any type of lighting you can imagine.

12. Solar Landscape Lighting

When you think of solar lighting, landscape lighting is probably the first thing to come to mind.

Solar landscape lighting technologies are inexpensive and readily available. You can find basic to high-end designs everywhere from your local hardware store to online shopping websites like Amazon.

These fixtures didn’t always provide the most light, but LED technology and enhanced batteries have changed that. Individual lighting fixtures now provide sufficient lighting with no wiring connections. Each lighting fixture has its own solar cell and rechargeable battery, which often generates enough energy to power your lights all night.

13. Solar Security Lighting

Solar lighting fixtures have become so reliable that they’re a great candidate for home security lighting as well. 

Like with landscape lighting, the batteries connected to solar security lights typically generate enough energy to last them through the night. This is especially true with motion-sensor options , which save stored energy for when you really need it. 

You can even find options with up to 3500 lumens. That’s enough light to illuminate your outdoor space and give your family peace of mind. Plus, water-resistant features mean you’ll never have to worry about product failure due to weather.

14. Solar Holiday Lights

That’s right — you can take advantage of solar during the holidays with solar-powered Christmas lights. After all, everyone’s budgets feel strained this time of year — don’t let electricity costs to power Christmas lights add to that!

Good Housekeeping reviewed the seven best solar Christmas lights for 2022 , with options ranging from simple white string lights to uniquely shaped options.

15. Indoor Solar Lighting

If you thought lighting had to be located outdoors for solar to power it, guess again. 

As with outdoor solar lights, these indoor fixtures have individual solar cells and rechargeable batteries. The difference is that you can often position the solar cells wherever they’ll get maximum sun exposure. And that means they’re not necessarily located in the same place as the lighting fixture itself.

Options range from desk lamps to pendant lighting . One especially innovative use of indoor solar lighting, featured on Mashable, is the Solatube skylight. It adds natural light while reducing energy use.

Solar Appliances

Appliances with low energy requirements may be able to rely on solar alone for power. Many larger appliances, such as refrigerators and washers and dryers, come in energy-efficient models that make them ideal for solar-powered homes.

16. Solar Ovens

Solar ovens , aka solar cookers, are a great way to cook when the power goes out, while camping or when you simply want to save on electricity costs. They work by gathering and trapping the sun’s thermal energy. 

For example, think about your car with its windows rolled up on a hot sunny day. The windows let in and trap the sun’s thermal energy — and the air inside gets hot as a result. It’s no wonder we often say our cars feel like an oven on really hot days!

Various types of solar ovens exist, and you can make most of them yourself with a handful of simple materials. However, if DIY isn’t for you, you can also purchase one .

17. Solar Cooler

If you’re still toting an ice-packed cooler when you head to the park or campground, it’s time to bring you up to speed.

Solar-powered coolers are now the go-to product. They ensure your food stays cool for longer and eliminate the issue of melted ice (and soggy sandwiches). Portable power stations receive energy from solar panels and then transfer that energy to the cooler when it’s in use.

Here are your six best options for solar-powered coolers in 2022 , five of which function as both refrigerators and freezers.

18. Solar Portable Bluetooth Speaker

Solar-powered Bluetooth speakers work just like the wireless speakers you’re used to. The difference is that you can charge them without electricity because they have built-in solar panels. 

This makes solar speakers perfect for anyone who spends a lot of time outdoors or on the go, such as while camping or traveling.

19. Solar Calculators

Did you know that solar-powered calculators have been around since the 1960s ? That’s right — you’ve probably used one before!

Solar calculators have tiny solar cells mounted onto them, usually at the top of the device. Because calculators require so little energy to work, the solar cells mean you’ll likely never have to charge the battery.

20. Solar Flashlights and Lanterns

When the power goes out or the sun goes down and you’re out of batteries, you’ll be glad you opted for a solar-powered flashlight or lantern. Some of the best options last up to 30 hours when fully charged, making them lifesavers in an emergency.

21. Wireless Solar Keyboard

Wireless keyboards offer a much better typing experience because you can place your keyboard wherever it’s most comfortable. Plus, you don’t have to deal with cords. 

But when you’re in the middle of an important project and the batteries die, you’ll wish you’d gone for a solar-powered keyboard. Here are 10 excellent solar keyboards to explore.

22. Solar Battery Chargers

In our connected world, phones and tablets are always with us (and, let’s face it, often running low on battery). Portable solar PV chargers keep our personal electronic devices charged — no matter where we are.

The technology to integrate solar cells into our phones already exists, and it’s been in watches since the 1970s. Researchers in Japan have even developed lightweight, water-resistant solar cells that we could someday sew into clothing to power devices.

23. Solar Security Cameras

Surprisingly, solar-powered security cameras don’t require any wires to function (unlike traditional ones). So rather than connecting to scrambled data cables, you can simply connect your solar security camera to Wi-Fi. And the cameras are also easy to install — you can put them virtually anywhere, whether an outlet is nearby or not. 

Batteries aren’t needed, so you don’t have to worry about replacing them every few months. With traditional cameras, you often have to take them down to recharge or switch out batteries. This process not only adds hassle but also interrupts your video footage. 

Lastly, solar-powered security cameras provide you with continuous recording. Compare that to traditional cameras, which often go into power-saving mode or record only if and when they detect motion. If you have a regular security camera, its motion detector must be on point — otherwise, you could have delays in your footage (or no footage at all). 

24. Solar Umbrellas

Another savvy solar-powered appliance includes a new table umbrella design that features solar panels ! 

Solar panels attach to the top of the umbrella and charge its built-in battery whenever sunlight shines. At night, the solar batteries power LED lights on the underside of the umbrella. 

Thanks to these solar-powered umbrella lights, you can play cards, read, write and do much more at night under an illuminated tabletop in your backyard.

25. Solar-Powered Wi-Fi Garbage Bins

Garbage bins that transmit Wi-Fi are becoming increasingly common in major U.S. cities. But they’re also picking up internationally in places like Stockholm, Amsterdam, Dublin and Hamburg. 

Bigbelly , a company that creates waste and recycling solutions for public spaces, founded the smart bins. And they’ve made a big impact on the cleanliness and Wi-Fi availability of city life. 

These solar-powered trash bins have built-in solar panels that generate energy to enable Wi-Fi. Then, passersby can take advantage of Wi-Fi hotspots while commuting. 

Granted, it might not seem ideal to stand next to a heaping-full, steaming trash can in the midst of summer. But free Wi-Fi never hurts — especially when green energy fuels it.

Home Beautification

Solar landscape lighting already goes a long way toward beautifying your outdoor space, but you can do even more with solar energy.

26. Solar Garden Decorations

The Importance of Solar Energy in Our Daily Life

We are reader-supported. When you buy through links on our site, we may earn affiliate commission.

All of the life that is on the earth can survive because of the sun. Every day, the energy given from the sun’s rays sustains life. It provides us with heat, light, health benefits and various other applications, like the widely used and known solar energy. Without the sun, the earth would be just a ball of rock without any life forms. 

The importance of solar energy in our daily life is more significant than any other thing in your life — besides water and food. Solar energy has been growing as a renewable and alternative energy source. That’s why it’s necessary to understand the importance of the sun’s power because, if you don’t already, you could very well be reliant on the sun for your daily energy needs. 

What Is Solar Energy?

What is solar energy anyways? It’s exactly as it sounds — solar energy is the energy you get from the sun. The energy that you see is light, and the energy you feel as heat is the sun. These are both constituted as solar radiation. 

All across the earth, this solar radiation varies. Hawaii receives a different amount of sunlight compared to Maine. Even places just a few miles away could experience varying amounts of solar radiation per year. 

One of the greatest benefits of solar energy is that it is clean and renewable. Most of the energy that American’s use comes from nonrenewable resources that emit carbon dioxide emissions. However, the sun’s energy can be captured, and in the process of turning it into electricity, very few to zero emissions are released. 

Additionally, the sun is renewable. It shines regardless of human processes on earth. Nonrenewable energy sources may run out sometime, but the sun will shine forever. You can always count on the sun to provide you with clean energy. 

Solar Energy Then

Solar energy is not a new concept. People centuries ago used the sun for daily activities and tasks. While people didn’t use the sun’s energy how it is commonly used today, it was still an essential source for them to be able to live and survive.

Have you ever watched a survival show where the person used the sun to start a fire or been in a science class where you used a magnifying glass to light a piece of paper on fire? That practice began in the 7th century B.C. The sun’s rays are concentrated with the magnifying glass, which heats something enough to start a fire.

Additionally, humans have used the sun’s heat for various purposes. Bathhouses were popular in ancient Rome. They used the sun to heat the water. Also, the sun’s heat has been used passively to heat homes or provide light, which is still used today. 

Humans have used the sun to cook meals as well. The multiple sunlight and solar energy applications have made it possible for humans to thrive on this earth. 

Solar Energy Now

Now, solar energy is harvested to power homes and businesses. The amount of sunlight that hits the earth in just over an hour would be enough to power the world’s energy needs for one year. This opportunity is tremendous, but not everyone is on board yet to switch to solar energy , and it would take time to add solar plants to places all around the world. 

The solar energy you know of today is provided through two main technologies — photovoltaics (PV) and concentrating solar thermal power (CSP). Photovoltaics is what you commonly see happening in solar panels. When the sun hits the panels, PV cells absorb the energy, which creates electrical charges to provide electricity. CSP uses mirrors to reflect sunlight onto receivers, which generate energy in the form of heat to produce electricity for larger companies.

Only about 2% of the world’s energy consumption comes from solar energy. This is a small percentage in comparison to other forms of energy. However, solar energy continues to grow. The resource is endless and astronomically better for the environment than nonrenewable sources, which is what activists for the environment are trying to prove.

Whether you use the sun’s wealth of energy to power your home or to gain vitamin D, you rely on it every day. Sure, you probably don’t use it to start fires or to heat your shower, but you do need it to eat since animals and plants use its energy to grow. You also need it to function throughout the day. Without the sun’s energy, there would be no you. 

Th e Future of Solar Energy in Daily Life

In the future, the importance of solar energy will be just as high as it has been in the past and is now. As more people adopt renewable energy, the demand for solar technologies will expand. Humans must make the switch to save the planet and to continue to thrive on Earth.

Examples of Solar Energy in Everyday Life

Humans have harnessed the sun’s energy for billions of years. From sun-drying foods and starting fires to sunrooms and drying clothes, we have tapped the warmth and energy of the sunlight since the beginning of time.

By the mid-19th century, the scare of running out of coal deposits drove the scientific community to come up with a better way to harness solar energy. And this led to the discovery of the photovoltaic effect and the invention of solar cells.

Since then, there is looking back for solar power and its applications. Using solar energy technologies and solar cells, countless inventions followed to utilize the sun’s energy in our daily lives. Solar cookers, solar calculators, solar water heaters, solar lighting, the list of uses of solar energy goes on.

Besides generating electricity, the sun’s energy has numerous direct applications. Moreover, solar energy is renewable and clean. And, this makes it the best alternative to fossil fuels.

Continue reading to learn about more examples of solar energy in everyday life. You might be surprised at how many items use this renewable energy resource!

How is solar energy used today?

Today photovoltaic technology is used to harness the sun’s energy in many ways. As we understand the advantages of solar energy and the harmful effects of burning fossil fuels, our reliance on solar technology is expanding day by day. 

One of the prime applications of solar technology is in the generation of electricity. Solar farms have come up in most parts of the world, helping solar energy gain a better share in the overall electricity production. Concentrated solar power technology has helped in furthering the green agenda even in places with less sunlight.

Besides electricity generation, solar power is widely used to heat homes and in solar water heaters. Instead of converting solar energy into electrical energy, it finds direct application as heat energy in these gadgets.

Another innovative application of solar energy is the passive solar energy systems for retaining warmth in homes. These are integrated into the design and construction of homes with specially-designed roofing and windows, besides alignment to ensure maximum exposure to the sunlight.

Here are some more common uses of solar energy in daily life.

Examples of solar energy in daily life

Installing a solar power system in your home or business will help you generate electricity using solar panels and feed it into the main switchboard for use by all electrical appliances. 

However, this demands substantial initial investment. If you are not up for this step, you can still harness solar energy for specific needs, like solar water heaters and using solar energy to heat indoor spaces. 

In addition to these applications, solar energy can be used in a variety of ways to meet our daily energy needs. Here are some of the lesser-known applications of solar energy in our everyday life.

1. Solar-powered pumps

Whenever you need to pump water, you use electric pumps linked to grid energy. Electric pumps take up lots of energy, especially if they need to be operated for longer periods. You can achieve the same result with a solar-powered pump. 

Usually, water pumps are used in solar water heating systems. When grid energy is used to pump water, your goal to go solar is getting diluted. Having a solar-powered pump as an add-on to the solar water heater can eliminate the need for grid energy in the process.

Though the entire setup comes at a higher cost, the operating cost is almost nothing. One of the advantages of solar technology is its low operation cost because of the absence of moving parts in it. 

Solar-powered pumps typically come with an in-built battery to store DC power. This can come in handy on rainy and cloudy days when the sun is absent and hot water is much needed.

2. Solar water heating for swimming pools

Heated swimming pools are a necessity in colder regions across the world. You can choose from two main options to resolve the problem of too cold water in your swimming pool. 

The cheaper of the two choices is a solar blanket. It looks essentially like a huge bubble wrap – a sheet with tiny bubbles of trapped air, big enough to cover the surface of the swinging pool. A solar blanket captures the sun’s energy during the daytime to raise the temperature of water in the pool and retain the heat at night. 

The downside of using a solar blanket is that it needs to be removed when you want to swim and spread out again after use. If you want to avoid this hassle, you can try the more expensive choice of installing a solar water heater to heat the pool water. 

A solar water heater has solar heating panels mounted on rooftops to capture the sun’s heat. The heat is conveyed to the pool water using a series of conduits circulating the water from the pool. As the pool water loses heat, it is circulated through these pipes to the solar heating panels, where they get heated up. The water is circulated back to the pool which raises the overall temperature of the swimming pool.

3. Solar chargers

Any device with a chargeable battery needs to be plugged into an electrical source and charged often. Such as mobile phones, laptops, tablets, etc. When you have many such devices, the electricity consumption for charging will be substantial.

You can eliminate the use of grid energy for charging needs by using a solar charger. They come with a solar panel system that produces DC power. As most rechargeable batteries work on DC, it would be easier and simpler to charge these devices directly. 

Solar chargers typically come with ports that let you plug in your rechargeable devices for charging. In case you have devices that need AC power, all you need to do is to add an inverter to convert DC to AC.

Depending on your energy needs, solar chargers of various capacities are available in the market.

• Best Solar Power Bank for Camping
• Best Solar Generator for Off-Grid Living
• Best Solar Generator for Refrigerator

4. Solar cookers

When you are cooking outdoors whether at home or while camping, solar cookers offer a pollution-free way of getting your food ready. They use the sun’s UV rays to heat the food.

There are a variety of solar cookers available in the market to suit diverse needs. Solar panel cooker, solar parabolic cooker, and solar box cooker are the main types of solar cookers. They differ in the way the sun’s energy is captured and utilized. Because of this, their efficiencies are also varied.

You can also make your own solar cooker using a cardboard box, pan, aluminum foil, and Styrofoam. The aluminum foil helps in capturing the solar energy and directs it to the pan in which the food is being cooked.

5. Solar outdoor lighting

One of the best uses of solar energy is for outdoor lighting needs. Its main components are a solar panel and a rechargeable battery to store the solar energy generated during the daytime for use at night. 

As the location of the lighting is outdoors, it will be already exposed to sunlight. The solar panels fixed on top of the lighting capture the sun’s energy and charge the battery when the sun is shining. This is used to turn the light on when it is dark. 

The capacity of the solar panels needed depends on the kind of bulb used in it and how long it is needed at night. With LED bulbs and good batteries, solar outdoor lighting can be managed with minimal solar panels. 

Besides avoiding the use of grid energy for lighting needs, these fixtures can help you avoid wires for connections.

6. Solar-powered exhaust fans

Again, a very simple way to utilize the free and abundant sun’s energy. We use exhaust or ventilation fans to improve air circulation indoors and to keep the temperature down. In indoor settings where air-conditioning is not available, ventilation fans are used as a low-cost solution.

Usually, these fans are connected to the switchboard and it will draw energy from the grid. Since most of them are operated for long hours, they consume huge amounts of energy, thus raising the utility bill. 

Instead, you can choose a solar-powered exhaust fan that works using a solar panel fitted on the outside wall. As long as the panels are sufficiently exposed to sunlight, they will produce enough solar energy to work the ventilation fan.

Not just exhaust fans, the same technology can be incorporated into regular fans as well for use in patios, garages, sheds, dog houses, and chicken coops to keep it cool in the summer months.

7. Pocket Calculators

After listing much larger devices that use solar power, a pocket calculator may seem inconsequential and irrelevant. The use of solar cells in calculators can help you reduce the use of batteries, thus lowering the quantity of toxic waste generated.

Most solar-powered calculators work on indirect sunlight and even in dimly-lit conditions. Some of them are dual powered with an added battery to work in poorly-lit settings.

Bottom line

Solar energy is a hot topic in the green movement. It’s good for our planet, but it can also be great for your wallet! 

If you were confused as to how or where to begin your “green” journey, this article must have helped you with some ideas. After all, each one of us should take a pledge to leave this beautiful planet intact if not better for the future generation than how we inherited it. 

Going solar would help you achieve this without compromising your quality of life.

The sun is the closest star to Earth . Even at a distance of 150 million kilometers (93 million miles), its gravitational pull holds the planet in orbit. It radiates light and heat, or solar energy , which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze. There would be no winds , ocean currents , or clouds to transport water. Solar energy has existed as long as the sun—about five billion years. While people have not been around that long, they have been using solar energy in a variety of ways for thousands of years. Solar energy is essential to agriculture —cultivating land, producing crops , and raising livestock . Developed about 10,000 years ago, agriculture had a key role in the rise of civilization . Solar techniques, such as crop rotation , increased harvests . Drying food using sun and wind prevented crops from spoiling . This surplus of food allowed for denser populations and structured societies. Early civilizations around the world positioned buildings to face south to gather heat and light. They used windows and skylights for the same reason, as well as to allow for air circulation. These are elements of solar architecture . Other aspects include using selective shading and choosing building materials with thermal mass , meaning they store heat, such as stone and concrete. Today, computer programs make applications easier and more precise . The greenhouse is another early solar development. By converting sunlight to heat, greenhouses make it possible to grow plants out of season and in climates that may not be suited for them. One of the earliest greenhouses dates to 30 C.E., before glass was even invented. Constructed from translucent sheets of mica , a thin mineral, it was built for the Roman emperor Tiberius , who wanted to be able to eat cucumbers all year. The general technique is the same today, although there have been many improvements to increase the variety and amount of crops grown.

On ce food is harvested , solar energy can be used to cook it. The first solar box cooker was built in 1767 by Horace de Saussure , a Swiss physicist. It reached temperatures of 87.8 degrees Celsius (190 degrees Fahrenheit) and was used to cook fruit. Today, there are many different types of solar cookers being used for cooking, drying and pasteurization, which slows the growth of microbes in food. Because they do not use fossil fuels , they are safe, do not produ ce pollution or cause deforestation .

Solar cookers are used in many parts of the world in growing numbers. It is estimated that there are half a million installed in India alone. India has the world’s two largest solar cooking systems, which can prepare food for 25,000 people daily. According to Indian Prime Minister Manmohan Singh , “Sin ce exhaustible energy sour ces in the country are limited, there is an urgent need to focus attention on development of renewable energy sour ces and use of energy efficient technologies.”

In Nicaragua, a modified solar cooker is being used to sterilize medical equipment at clinics. Solar thermal energy can be used to heat water. First introduced in the late 1800s, the solar water heater was a big improvement over stoves that burned wood or coal because it was cleaner and cost less to operate. They were very popular for American homes in sunny places, including the U.S. states of Arizona, Florida, and California. However, in the early 1900s, low-cost oil and natural gas became available and solar water systems began to be replaced. Today, they are not only popular again; they are becoming the norm in some countries, including China, Greece, and Japan. They are even required to be used in any new construction in Australia, Israel, and Spain. Besides heating water, solar energy can be used to make it potable , or suitable for drinking. One method is solar disinfection (SODIS). Developed in the 1980s, SODIS involves filling plastic soda bottles with water then exposing them to sunlight for several hours. This process reduces the viruses , bacteria and protozoa in water. More than two million people in 28 developing nations use this method daily for their drinking water. Solar power —the conversion of sunlight into electricity —is yet another application of solar technology. This can be done in a number of ways. The two most common are photovoltaic (solar cells) and concentrating solar power. Solar cells convert sunlight directly into electricity. The amount of power generated by each cell is very low. Therefore, large numbers of cells must be grouped together, like the panels mounted on the roof of a house, to generate enough power. The first solar cell was constructed in the 1880s. The earliest major application was on the American satellite Vanguard I , launched in 1958. A radio transmitter powered by solar cells operated for about seven years; one using conventional batteries lasted only 20 days. Since then, solar cells have become the established power source for satellites, including those used in the telecommunications industry. On Earth, solar cells are used for everything from calculators and watches to homes, commercial buildings, and even stadiums. Kaohsiung World Stadium in Taiwan, completed in 2009 to host the World Games, has more than 8,800 solar panels on its roof. Charles Lin, director of Taiwan’s Bureau of Public Works, said, “The stadium's solar energy panels will make the venue self-sufficient in electricity needs.” When the stadium is not in use, it can power 80 percent of the surrounding neighborhood. Unlike solar cells, which use sunlight to generate electricity, concentrating solar power technology uses the sun’s heat. Lenses or mirrors focus sunlight into a small beam that can be used to operate a boiler. That produces steam to run turbines to generate electricity. This method will be used at the Solana Generating Station, which is being built by the APS utility company outside of Phoenix, Arizona, in the United States. When completed in 2012, Solana will be one of the largest solar power stations in the world. Once operating at full capacity, it will serve 70,000 homes. “This is a major milestone for Arizona in our efforts to increase the amount of renewable energy available in the United States,” said former Arizona Gov. Janet Napolitano. There are some challenges with solar power. First, it is intermittent , or not continuous. When there is no sun—at night, for example—power cannot be generated. In order to provide continuous power, either storage or other energy sources, such as wind power, must be used. Second, while both photovoltaic and concentrating solar power can be used virtually anywhere, the equipment they require takes up a lot of space. Installation , except for on existing structures, can have a negative impact on the ecosystem by displacing plants and wildlife. Lastly, the cost to collect, convert and store solar power is very high. However, as technological advancements are made and demand rises, the costs are dropping. Fossil fuels, such as coal, oil and natural gas, currently produce most of our electric and engine power. They also produce almost all of our pollution. Plus, they are nonrenewable, meaning there is a limited supply. The sun, on the other hand, offers free and clean energy in abundance. In fact, it gives much more energy than we can ever possibly use. The only questions are how and when we will take full advantage of it.

Electrified Nation Ranked third in the world in population, the United States uses more electricity than any other country, even the entire European Union of 27 nations.

African Energy 16,000 square kilometers (9,942 square miles) of solar power plants in North Africa could generate enough electricity for all of Europe.

Solar Power In 15 minutes, the sun radiates as much energy as people use in all forms in an entire year.

The ongoing development of solar technologies is giving more homes the solar energy options to save up on their electricity and utility bills. ‘Going Green’ is one of the initiatives that has been promoted to inform people about the various uses and benefits of using such sustainable and renewable energy sources.

It does have an initial cost that needs to be taken care of so that it can be up and running, but once you have it installed there is no looking back. Below are a few uses it has for your home that can make your daily life better.

Power up your Home

Having solar panels on the roof of your home can save you a ton on electricity. They capture the sun rays in the day and convert it into electricity. You could use it to power up your appliances, fans, machinery, computer, or even an entire building. Santa Cruz solar companies are on the rise for the use of solar panels for residential places.

Solar Heating

Instead of collecting heat from the sun to convert it into electricity, it uses thermal devices to increase the temperature of a component. You could use it to heat water, solar rooms and swimming pools. It can also help you cool the water at night, during summers.

Indoor and Outdoor Lighting

One of the most common uses solar energy has, is to use it for lighting, be it indoors or outdoors. The battery chargers can be charged during the day when there is sunlight and it can use the stored energy during the night time.

Solar Charging

Solar energy can also be considered to charge batteries around your home. As the technology is advancing so are various gadgets. There are various solar chargers available that can be used in places where you have no access to electricity, for example, when you are traveling or going camping. Imagine having a personal charger without the use of electricity, isn’t it amazing?

Solar Cooking

There are solar ovens and cookers that are available. On sunny days, you can easily cook outside without having to use your conventional methods like the electricity or gas. It is considered, cooking inside the box, which can be built yourself. The materials you would need are a box, pan, aluminum foil, cooking bag, duct tape, Styrofoam and a thermometer, and you have a solar cooking area ready.

Overall, it is a great investment as it gives you great returns. It is certainly one of the best sources of energy as it does not depend on gas, coal or oil. Solar energy has also been used in transportation, which can help power up aircraft, trains, and even space crafts.

Importance of solar energy

Solar energy is considered to be the best option for the people and modern industries as it belongs to the renewable category. With the disappearance of the fossil fuels from the planet and their rising costs has forced countries to switch over to a sustainable energy source. Sun is the biggest energy supplier and is fully capable of meeting the energy needs of earth in the distant future.

No pollution: Used as an alternative to petrol, the solar power doesn’t pollute the environment and delivers clean and reliable energy to the users. It doesn’t emit harmful carbonic gases into the atmosphere. As a result, people can ensure electrical supply to their homes without burning coal. Moreover, the users do not have to grapple with the storage issues related to fossil and nuclear fuel. Solar panels also do not make noise and emit toxic fumes into the atmosphere.

Also read: Importance of trees

Renewable energy: As long as the sun exists in the space, solar energy can be generated for free. It is a game changer as far as ensuring energy security to the people. With rising electricity bills in the household, people are increasingly installing solar panels on their rooftops to supplement the production of electricity. It will help them to reduce the energy expenditure to a great extent.  Solar energy can provide power in places with remote accessibility. The only drawback of the solar panel is that it might not work full throttle during a cloudy day.

Cost effective maintenance: Advancement in technology has helped to lower the maintenance of the solar panels. In order to increase power, more such devices can be added to the system. Usage of solar energy has resolved the problems of many homeowners. The cost of the solar panel might seem to be more, however, it can easily be recovered after 10 years. One of the most important benefits of the solar energy is that it doesn’t initiate recurring cost.

Simplistic installation: Unlike the conventional mode of electricity, the installation of the solar panels is quite simple. Due to lack of wires, the total cost of upkeep is drastically reduced. In addition, the panels do not require space as they can b easily placed on the roof top of the building or the single family homes. Since the solar energy is installed in a distributed fashion, large-scale investment is not required.

Long term warranty: Solar panels can last for a very long time as various companies provide warranties ranging from 20 to 25 years. Since the device doesn’t contain moving mechanical parts, they are bound to last for a very long time. Solar energy has been providing powers to the areas where it is not possible to supply electricity in conventional mode.

Conclusion: The world is increasingly looking for alternate options to the coal which is a polluted source of electricity. It is vital for the energy-hungry economies around the world to rely on plenty of sunshine to generate renewable energy source such as solar power. In a nutshell, it can be said that solar energy is the harbinger of independence from the clutches of fossil fuels.

5 thoughts on “ Importance of solar energy ”

Solar energy is the best source of energy. It does not harm the environment and sun is not going anywhere soon. I hope we start using solar energy more and more in our lives. I set up a solar panel on my roof last month, I’m doing my bit.

Ya Mr mack, you are doing well at your extent. Thanks from me. I appreciate your work.

Although solar energy is good for the environment and all that, but it’s way too costly to set up these plants on large scale. You need a huge piece of land as well as millions of investment. I think with more advancements, they will be able to reduce the size of the solar panel and it will still absorb more energy. Same like memory devices, we can store more memory in less space compared to the past.

I am so disappointed in the lack of development of inexpensive solar panels. Just today I saw an ad for a 45 watt solar panel selling for $140. 45 watts! It would cost a fortune to buy enough solar panels for home use, say 15Kw to 25Kw. Totally unaffordable.

well, consider not paying bills for the next 20 years … except maintenance

Solar energy is environmentally friendly technology, a great energy supply and one of the most significant renewable and green energy sources. It plays a substantial role in achieving sustainable development energy solutions. Therefore, the massive amount of solar energy attainable daily makes it a very attractive resource for generating electricity. Both technologies, applications of concentrated solar power or solar photovoltaics, are always under continuous development to fulfil our energy needs. Hence, a large installed capacity of solar energy applications worldwide, in the same context, supports the energy sector and meets the employment market to gain sufficient development. This paper highlights solar energy applications and their role in sustainable development and considers renewable energy’s overall employment potential. Thus, it provides insights and analysis on solar energy sustainability, including environmental and economic development. Furthermore, it has identified the contributions of solar energy applications in sustainable development by providing energy needs, creating jobs opportunities and enhancing environmental protection. Finally, the perspective of solar energy technology is drawn up in the application of the energy sector and affords a vision of future development in this domain.

With reference to the recommendations of the UN, the Climate Change Conference, COP26, was held in Glasgow , UK, in 2021. They reached an agreement through the representatives of the 197 countries, where they concurred to move towards reducing dependency on coal and fossil-fuel sources. Furthermore, the conference stated ‘the various opportunities for governments to prioritize health and equity in the international climate movement and sustainable development agenda’. Also, one of the testaments is the necessity to ‘create energy systems that protect and improve climate and health’ [ 1 , 2 ].

The Paris Climate Accords is a worldwide agreement on climate change signed in 2015, which addressed the mitigation of climate change, adaptation and finance. Consequently, the representatives of 196 countries concurred to decrease their greenhouse gas emissions [ 3 ]. The Paris Agreement is essential for present and future generations to attain a more secure and stable environment. In essence, the Paris Agreement has been about safeguarding people from such an uncertain and progressively dangerous environment and ensuring everyone can have the right to live in a healthy, pollutant-free environment without the negative impacts of climate change [ 3 , 4 ].

In recent decades, there has been an increase in demand for cleaner energy resources. Based on that, decision-makers of all countries have drawn up plans that depend on renewable sources through a long-term strategy. Thus, such plans reduce the reliance of dependence on traditional energy sources and substitute traditional energy sources with alternative energy technology. As a result, the global community is starting to shift towards utilizing sustainable energy sources and reducing dependence on traditional fossil fuels as a source of energy [ 5 , 6 ].

In 2015, the UN adopted the sustainable development goals (SDGs) and recognized them as international legislation, which demands a global effort to end poverty, safeguard the environment and guarantee that by 2030, humanity lives in prosperity and peace. Consequently, progress needs to be balanced among economic, social and environmental sustainability models [ 7 ].

Many national and international regulations have been established to control the gas emissions and pollutants that impact the environment [ 8 ]. However, the negative effects of increased carbon in the atmosphere have grown in the last 10 years. Production and use of fossil fuels emit methane (CH 4 ), carbon dioxide (CO 2 ) and carbon monoxide (CO), which are the most significant contributors to environmental emissions on our planet. Additionally, coal and oil, including gasoline, coal, oil and methane, are commonly used in energy for transport or for generating electricity. Therefore, burning these fossil fuel s is deemed the largest emitter when used for electricity generation, transport, etc. However, these energy resources are considered depleted energy sources being consumed to an unsustainable degree [ 9–11 ].

Energy is an essential need for the existence and growth of human communities. Consequently, the need for energy has increased gradually as human civilization has progressed. Additionally, in the past few decades, the rapid rise of the world’s population and its reliance on technological developments have increased energy demands. Furthermore, green technology sources play an important role in sustainably providing energy supplies, especially in mitigating climate change [ 5 , 6 , 8 ].

Currently, fossil fuels remain dominant and will continue to be the primary source of large-scale energy for the foreseeable future; however, renewable energy should play a vital role in the future of global energy. The global energy system is undergoing a movement towards more sustainable sources of energy [ 12 , 13 ].

Power generation by fossil-fuel resources has peaked, whilst solar energy is predicted to be at the vanguard of energy generation in the near future. Moreover, it is predicted that by 2050, the generation of solar energy will have increased to 48% due to economic and industrial growth [ 13 , 14 ].

In recent years, it has become increasingly obvious that the globe must decrease greenhouse gas emissions by 2050, ideally towards net zero, if we are to fulfil the Paris Agreement’s goal to reduce global temperature increases [ 3 , 4 ]. The net-zero emissions complement the scenario of sustainable development assessment by 2050. According to the agreed scenario of sustainable development, many industrialized economies must achieve net-zero emissions by 2050. However, the net-zero emissions 2050 brought the first detailed International Energy Agency (IEA) modelling of what strategy will be required over the next 10 years to achieve net-zero carbon emissions worldwide by 2050 [ 15–17 ].

The global statistics of greenhouse gas emissions have been identified; in 2019, there was a 1% decrease in CO 2 emissions from the power industry; that figure dropped by 7% in 2020 due to the COVID-19 crisis, thus indicating a drop in coal-fired energy generation that is being squeezed by decreasing energy needs, growth of renewables and the shift away from fossil fuels. As a result, in 2020, the energy industry was expected to generate ~13 Gt CO 2 , representing ~40% of total world energy sector emissions related to CO 2 . The annual electricity generation stepped back to pre-crisis levels by 2021, although due to a changing ‘fuel mix’, the CO 2 emissions in the power sector will grow just a little before remaining roughly steady until 2030 [ 15 ].

Therefore, based on the information mentioned above, the advantages of solar energy technology are a renewable and clean energy source that is plentiful, cheaper costs, less maintenance and environmentally friendly, to name but a few. The significance of this paper is to highlight solar energy applications to ensure sustainable development; thus, it is vital to researchers, engineers and customers alike. The article’s primary aim is to raise public awareness and disseminate the culture of solar energy usage in daily life, since moving forward, it is the best. The scope of this paper is as follows. Section 1 represents a summary of the introduction. Section 2 represents a summary of installed capacity and the application of solar energy worldwide. Section 3 presents the role of solar energy in the sustainable development and employment of renewable energy. Section 4 represents the perspective of solar energy. Finally, Section 5 outlines the conclusions and recommendations for future work.

1.1 Installed capacity of solar energy

The history of solar energy can be traced back to the seventh century when mirrors with solar power were used. In 1893, the photovoltaic (PV) effect was discovered; after many decades, scientists developed this technology for electricity generation [ 18 ]. Based on that, after many years of research and development from scientists worldwide, solar energy technology is classified into two key applications: solar thermal and solar PV.

PV systems convert the Sun’s energy into electricity by utilizing solar panels. These PV devices have quickly become the cheapest option for new electricity generation in numerous world locations due to their ubiquitous deployment. For example, during the period from 2010 to 2018, the cost of generating electricity by solar PV plants decreased by 77%. However, solar PV installed capacity progress expanded 100-fold between 2005 and 2018. Consequently, solar PV has emerged as a key component in the low-carbon sustainable energy system required to provide access to affordable and dependable electricity, assisting in fulfilling the Paris climate agreement and in achieving the 2030 SDG targets [ 19 ].

The installed capacity of solar energy worldwide has been rapidly increased to meet energy demands. The installed capacity of PV technology from 2010 to 2020 increased from 40 334 to 709 674 MW, whereas the installed capacity of concentrated solar power (CSP) applications, which was 1266 MW in 2010, after 10 years had increased to 6479 MW. Therefore, solar PV technology has more deployed installations than CSP applications. So, the stand-alone solar PV and large-scale grid-connected PV plants are widely used worldwide and used in space applications. Fig. 1 represents the installation of solar energy worldwide.

Installation capacity of solar energy worldwide [ 20 ].

1.2 Application of solar energy

Energy can be obtained directly from the Sun—so-called solar energy. Globally, there has been growth in solar energy applications, as it can be used to generate electricity, desalinate water and generate heat, etc. The taxonomy of applications of solar energy is as follows: (i) PVs and (ii) CSP. Fig. 2 details the taxonomy of solar energy applications.

The taxonomy of solar energy applications.

Solar cells are devices that convert sunlight directly into electricity; typical semiconductor materials are utilized to form a PV solar cell device. These materials’ characteristics are based on atoms with four electrons in their outer orbit or shell. Semiconductor materials are from the periodic table’s group ‘IV’ or a mixture of groups ‘IV’ and ‘II’, the latter known as ‘II–VI’ semiconductors [ 21 ]. Additionally, a periodic table mixture of elements from groups ‘III’ and ‘V’ can create ‘III–V’ materials [ 22 ].

PV devices, sometimes called solar cells, are electronic devices that convert sunlight into electrical power. PVs are also one of the rapidly growing renewable-energy technologies of today. It is therefore anticipated to play a significant role in the long-term world electricity-generating mixture moving forward.

Solar PV systems can be incorporated to supply electricity on a commercial level or installed in smaller clusters for mini-grids or individual usage. Utilizing PV modules to power mini-grids is a great way to offer electricity to those who do not live close to power-transmission lines, especially in developing countries with abundant solar energy resources. In the most recent decade, the cost of producing PV modules has dropped drastically, giving them not only accessibility but sometimes making them the least expensive energy form. PV arrays have a 30-year lifetime and come in various shades based on the type of material utilized in their production.

The most typical method for solar PV desalination technology that is used for desalinating sea or salty water is electrodialysis (ED). Therefore, solar PV modules are directly connected to the desalination process. This technique employs the direct-current electricity to remove salt from the sea or salty water.

The technology of PV–thermal (PV–T) comprises conventional solar PV modules coupled with a thermal collector mounted on the rear side of the PV module to pre-heat domestic hot water. Accordingly, this enables a larger portion of the incident solar energy on the collector to be converted into beneficial electrical and thermal energy.

A zero-energy building is a building that is designed for zero net energy emissions and emits no carbon dioxide. Building-integrated PV (BIPV) technology is coupled with solar energy sources and devices in buildings that are utilized to supply energy needs. Thus, building-integrated PVs utilizing thermal energy (BIPV/T) incorporate creative technologies such as solar cooling [ 23 ].

A PV water-pumping system is typically used to pump water in rural, isolated and desert areas. The system consists of PV modules to power a water pump to the location of water need. The water-pumping rate depends on many factors such as pumping head, solar intensity, etc.

A PV-powered cathodic protection (CP) system is designed to supply a CP system to control the corrosion of a metal surface. This technique is based on the impressive current acquired from PV solar energy systems and is utilized for burying pipelines, tanks, concrete structures, etc.

Concentrated PV (CPV) technology uses either the refractive or the reflective concentrators to increase sunlight to PV cells [ 24 , 25 ]. High-efficiency solar cells are usually used, consisting of many layers of semiconductor materials that stack on top of each other. This technology has an efficiency of >47%. In addition, the devices produce electricity and the heat can be used for other purposes [ 26 , 27 ].

For CSP systems, the solar rays are concentrated using mirrors in this application. These rays will heat a fluid, resulting in steam used to power a turbine and generate electricity. Large-scale power stations employ CSP to generate electricity. A field of mirrors typically redirect rays to a tall thin tower in a CSP power station. Thus, numerous large flat heliostats (mirrors) are used to track the Sun and concentrate its light onto a receiver in power tower systems, sometimes known as central receivers. The hot fluid could be utilized right away to produce steam or stored for later usage. Another of the great benefits of a CSP power station is that it may be built with molten salts to store heat and generate electricity outside of daylight hours.

Mirrored dishes are used in dish engine systems to focus and concentrate sunlight onto a receiver. The dish assembly tracks the Sun’s movement to capture as much solar energy as possible. The engine includes thin tubes that work outside the four-piston cylinders and it opens into the cylinders containing hydrogen or helium gas. The pistons are driven by the expanding gas. Finally, the pistons drive an electric generator by turning a crankshaft.

A further water-treatment technique, using reverse osmosis, depends on the solar-thermal and using solar concentrated power through the parabolic trough technique. The desalination employs CSP technology that utilizes hybrid integration and thermal storage allows continuous operation and is a cost-effective solution. Solar thermal can be used for domestic purposes such as a dryer. In some countries or societies, the so-called food dehydration is traditionally used to preserve some food materials such as meats, fruits and vegetables.

Sustainable energy development is defined as the development of the energy sector in terms of energy generating, distributing and utilizing that are based on sustainability rules [ 28 ]. Energy systems will significantly impact the environment in both developed and developing countries. Consequently, the global sustainable energy system must optimize efficiency and reduce emissions [ 29 ].

The sustainable development scenario is built based on the economic perspective. It also examines what activities will be required to meet shared long-term climate benefits, clean air and energy access targets. The short-term details are based on the IEA’s sustainable recovery strategy, which aims to promote economies and employment through developing a cleaner and more reliable energy infrastructure [ 15 ]. In addition, sustainable development includes utilizing renewable-energy applications, smart-grid technologies, energy security, and energy pricing, and having a sound energy policy [ 29 ].

The demand-side response can help meet the flexibility requirements in electricity systems by moving demand over time. As a result, the integration of renewable technologies for helping facilitate the peak demand is reduced, system stability is maintained, and total costs and CO 2 emissions are reduced. The demand-side response is currently used mostly in Europe and North America, where it is primarily aimed at huge commercial and industrial electricity customers [ 15 ].

International standards are an essential component of high-quality infrastructure. Establishing legislative convergence, increasing competition and supporting innovation will allow participants to take part in a global world PV market [ 30 ]. Numerous additional countries might benefit from more actively engaging in developing global solar PV standards. The leading countries in solar PV manufacturing and deployment have embraced global standards for PV systems and highly contributed to clean-energy development. Additional assistance and capacity-building to enhance quality infrastructure in developing economies might also help support wider implementation and compliance with international solar PV standards. Thus, support can bring legal requirements and frameworks into consistency and give additional impetus for the trade of secure and high-quality solar PV products [ 19 ].

Continuous trade-led dissemination of solar PV and other renewable technologies will strengthen the national infrastructure. For instance, off-grid solar energy alternatives, such as stand-alone systems and mini-grids, could be easily deployed to assist healthcare facilities in improving their degree of services and powering portable testing sites and vaccination coolers. In addition to helping in the immediate medical crisis, trade-led solar PV adoption could aid in the improving economy from the COVID-19 outbreak, not least by providing jobs in the renewable-energy sector, which are estimated to reach >40 million by 2050 [ 19 ].

The framework for energy sustainability development, by the application of solar energy, is one way to achieve that goal. With the large availability of solar energy resources for PV and CSP energy applications, we can move towards energy sustainability. Fig. 3 illustrates plans for solar energy sustainability.

Framework for solar energy applications in energy sustainability.

The environmental consideration of such applications, including an aspect of the environmental conditions, operating conditions, etc., have been assessed. It is clean, friendly to the environment and also energy-saving. Moreover, this technology has no removable parts, low maintenance procedures and longevity.

Economic and social development are considered by offering job opportunities to the community and providing cheaper energy options. It can also improve people’s income; in turn, living standards will be enhanced. Therefore, energy is paramount, considered to be the most vital element of human life, society’s progress and economic development.

As efforts are made to increase the energy transition towards sustainable energy systems, it is anticipated that the next decade will see a continued booming of solar energy and all clean-energy technology. Scholars worldwide consider research and innovation to be substantial drivers to enhance the potency of such solar application technology.

2.1 Employment from renewable energy

The employment market has also boomed with the deployment of renewable-energy technology. Renewable-energy technology applications have created >12 million jobs worldwide. The solar PV application came as the pioneer, which created >3 million jobs. At the same time, while the solar thermal applications (solar heating and cooling) created >819 000 jobs, the CSP attained >31 000 jobs [ 20 ].

According to the reports, although top markets such as the USA, the EU and China had the highest investment in renewables jobs, other Asian countries have emerged as players in the solar PV panel manufacturers’ industry [ 31 ].

Solar energy employment has offered more employment than other renewable sources. For example, in the developing countries, there was a growth in employment chances in solar applications that powered ‘micro-enterprises’. Hence, it has been significant in eliminating poverty, which is considered the key goal of sustainable energy development. Therefore, solar energy plays a critical part in fulfilling the sustainability targets for a better plant and environment [ 31 , 32 ]. Fig. 4 illustrates distributions of world renewable-energy employment.

World renewable-energy employment [ 20 ].

The world distribution of PV jobs is disseminated across the continents as follows. There was 70% employment in PV applications available in Asia, while 10% is available in North America, 10% available in South America and 10% availability in Europe. Table 1 details the top 10 countries that have relevant jobs in Asia, North America, South America and Europe.

List of the top 10 countries that created jobs in solar PV applications [ 19 , 33 ]

Solar energy investments can meet energy targets and environmental protection by reducing carbon emissions while having no detrimental influence on the country’s development [ 32 , 34 ]. In countries located in the ‘Sunbelt’, there is huge potential for solar energy, where there is a year-round abundance of solar global horizontal irradiation. Consequently, these countries, including the Middle East, Australia, North Africa, China, the USA and Southern Africa, to name a few, have a lot of potential for solar energy technology. The average yearly solar intensity is >2800 kWh/m 2 and the average daily solar intensity is >7.5 kWh/m 2 . Fig. 5 illustrates the optimum areas for global solar irradiation.

World global solar irradiation map [ 35 ].

The distribution of solar radiation and its intensity are two important factors that influence the efficiency of solar PV technology and these two parameters vary among different countries. Therefore, it is essential to realize that some solar energy is wasted since it is not utilized. On the other hand, solar radiation is abundant in several countries, especially in developing ones, which makes it invaluable [ 36 , 37 ].

Worldwide, the PV industry has benefited recently from globalization, which has allowed huge improvements in economies of scale, while vertical integration has created strong value chains: as manufacturers source materials from an increasing number of suppliers, prices have dropped while quality has been maintained. Furthermore, the worldwide incorporated PV solar device market is growing fast, creating opportunities enabling solar energy firms to benefit from significant government help with underwriting, subsides, beneficial trading licences and training of a competent workforce, while the increased rivalry has reinforced the motivation to continue investing in research and development, both public and private [ 19 , 33 ].

The global outbreak of COVID-19 has impacted ‘cross-border supply chains’ and those investors working in the renewable-energy sector. As a result, more diversity of solar PV supply-chain processes may be required in the future to enhance long-term flexibility versus exogenous shocks [ 19 , 33 ].

It is vital to establish a well-functioning quality infrastructure to expand the distribution of solar PV technologies beyond borders and make it easier for new enterprises to enter solar PV value chains. In addition, a strong quality infrastructure system is a significant instrument for assisting local firms in meeting the demands of trade markets. Furthermore, high-quality infrastructure can help reduce associated risks with the worldwide PV project value chain, such as underperforming, inefficient and failing goods, limiting the development, improvement and export of these technologies. Governments worldwide are, at various levels, creating quality infrastructure, including the usage of metrology i.e. the science of measurement and its application, regulations, testing procedures, accreditation, certification and market monitoring [ 33 , 38 ].

The perspective is based on a continuous process of technological advancement and learning. Its speed is determined by its deployment, which varies depending on the scenario [ 39 , 40 ]. The expense trends support policy preferences for low-carbon energy sources, particularly in increased energy-alteration scenarios. Emerging technologies are introduced and implemented as quickly as they ever have been before in energy history [ 15 , 33 ].

The CSP stations have been in use since the early 1980s and are currently found all over the world. The CSP power stations in the USA currently produce >800 MW of electricity yearly, which is sufficient to power ~500 000 houses. New CSP heat-transfer fluids being developed can function at ~1288 o C, which is greater than existing fluids, to improve the efficiency of CSP systems and, as a result, to lower the cost of energy generated using this technology. Thus, as a result, CSP is considered to have a bright future, with the ability to offer large-scale renewable energy that can supplement and soon replace traditional electricity-production technologies [ 41 ]. The DESERTEC project has drawn out the possibility of CSP in the Sahara Desert regions. When completed, this investment project will have the world’s biggest energy-generation capacity through the CSP plant, which aims to transport energy from North Africa to Europe [ 42 , 43 ].

The costs of manufacturing materials for PV devices have recently decreased, which is predicted to compensate for the requirements and increase the globe’s electricity demand [ 44 ]. Solar energy is a renewable, clean and environmentally friendly source of energy. Therefore, solar PV application techniques should be widely utilized. Although PV technology has always been under development for a variety of purposes, the fact that PV solar cells convert the radiant energy from the Sun directly into electrical power means it can be applied in space and in terrestrial applications [ 38 , 45 ].

In one way or another, the whole renewable-energy sector has a benefit over other energy industries. A long-term energy development plan needs an energy source that is inexhaustible, virtually accessible and simple to gather. The Sun rises over the horizon every day around the globe and leaves behind ~108–1018 kWh of energy; consequently, it is more than humanity will ever require to fulfil its desire for electricity [ 46 ].

The technology that converts solar radiation into electricity is well known and utilizes PV cells, which are already in use worldwide. In addition, various solar PV technologies are available today, including hybrid solar cells, inorganic solar cells and organic solar cells. So far, solar PV devices made from silicon have led the solar market; however, these PVs have certain drawbacks, such as expenditure of material, time-consuming production, etc. It is important to mention here the operational challenges of solar energy in that it does not work at night, has less output in cloudy weather and does not work in sandstorm conditions. PV battery storage is widely used to reduce the challenges to gain high reliability. Therefore, attempts have been made to find alternative materials to address these constraints. Currently, this domination is challenged by the evolution of the emerging generation of solar PV devices based on perovskite, organic and organic/inorganic hybrid materials.

This paper highlights the significance of sustainable energy development. Solar energy would help steady energy prices and give numerous social, environmental and economic benefits. This has been indicated by solar energy’s contribution to achieving sustainable development through meeting energy demands, creating jobs and protecting the environment. Hence, a paramount critical component of long-term sustainability should be investigated. Based on the current condition of fossil-fuel resources, which are deemed to be depleting energy sources, finding an innovative technique to deploy clean-energy technology is both essential and expected. Notwithstanding, solar energy has yet to reach maturity in development, especially CSP technology. Also, with growing developments in PV systems, there has been a huge rise in demand for PV technology applications all over the globe. Further work needs to be undertaken to develop energy sustainably and consider other clean energy resources. Moreover, a comprehensive experimental and validation process for such applications is required to develop cleaner energy sources to decarbonize our planet.

Solar energy is sustainable, renewable, and plentiful. As the cost of using solar to produce electricity goes down each year, many Americans are increasingly switching to solar. Now, there are over a million solar installations across the country. Below are additional benefits of switching to solar electricity.

Cost Savings

Financial returns and lower monthly utility bills are major incentives for going solar. The exact savings you will see with solar depends on the following: 

• Electricity consumption
• Solar energy system size
• Whether you purchase or lease your system
• Direct hours of daily sunlight
• Size and angle of roof
• Local electricity rates .

A solar electric system provides an opportunity for anyone who is looking to reduce monthly utility bills and make a long-term, low-risk investment.

Increased Home Value

Solar panels are viewed as upgrades, like a renovated kitchen or a finished basement, so purchasing a solar energy system will likely increase your home’s value. Studies show that homeowners pay a premium for a solar home; one study by Lawrence Berkeley National Laboratory showed that on average, solar increased the value of a home by about $15,000. Although market factors like electricity rates and system size may impact the size of the premium, solar homes can sell for more than homes without PV. Learn more about solar and real estate .

Solar Works Everywhere

The solar resource of the United States is enormous.  In fact, just one hour of noontime summer sun is equal to the annual U.S. electricity demand.  Most states in the United States have good-to-excellent solar resource. Even places with relatively low solar resources, such as the Pacific Northwest and Alaska, can experience cost savings, and have similar solar resources to countries that have widely developed solar PV, like Germany.

Environmental

Each kilowatt-hour (kWh) of solar that is generated will substantially reduce greenhouse gas emissions like CO 2 , as well as other dangerous pollutants such as sulfur oxides, nitrogen oxides and particulate matter.  Solar also reduces water consumption and withdrawal.
