500 Words Essay On Solar Energy

Life on earth is impossible without the sun and the energy it generates. Humans are no different from other organisms on this planet in that we are entirely dependent on the sun's energy, also known as solar energy; this dependence dates back to the beginning of time.

Solar Energy

We have the privilege of using solar energy as long as the sun is shining because it is a renewable power source. It is utilised by photosynthetic organisms like plants and some bacteria as "producers," who then supply food to other organisms at all levels of the food chain, known as "consumers." Reptiles and other cold-blooded animals run on solar energy daily. Humans have utilised it for many purposes, such as cooking and drying, and in the present day, we are using it to produce electricity.

Thermal radiation and light energy are provided by solar energy as well. These two energies are equally crucial.

The Earth is surrounded by solar radiation, which causes the oceans (which cover 71% of the planet) to evaporate due to the heat radiation. The vapour then circulates in a process known as the "water cycle," which in turn controls the planet's temperature. Solar energy also melts ice caps and glaciers, releasing potable water into the environment. Since everyone relies on light to keep things moving, the use of light is inexplicable.

There are several benefits and drawbacks to using solar energy.

Advantages of Solar Energy

Solar energy is completely free to use and requires no work to produce.

Solar energy applications can be used to generate electricity in rural and remote areas where conventional electricity is difficult to come by.

The harnessing and production of this clean energy have no adverse effects on the environment.

We have an endless supply of this energy as long as the sun continues to shine. It is entirely renewable. This is a short time compared to fossil fuel, which lasts for only 20 to 30 years.

Solar energy can charge calculators and solar cell batteries in large quantities.

Disadvantages of Solar Energy

Although it is free to produce, the machinery needed to harness it is quite expensive.

The maintenance and labour charges are costly for the installations.

For the installations to even produce enough energy, a very large area is needed.

Compared to traditional energy sources like fossil fuels, the amount of energy that has been harnessed is minimal.

Solar energy can be harnessed for various purposes during the day, when there is a lot of sunlight available.

My Experience With Solar Energy

I recently went to a science fair where I saw various solar energy projects, such as photoreceptive power cells, solar water heaters, and solar cookers, that produced electricity and used other types of solar energy. I realised there that solar energy has a broad range of applications, is made at a very low cost per individual, and protects our environment from pollution. It was also a good idea to encourage my village to use solar water heaters and panels. And finally, to promote clean energy, we must all move forward with the same concept.

Solar energy is a blessing from the sky that can help us transform urban life and make more sustainable houses and families. The systems mentioned here are the main principles behind our use of solar energy and they are being worked on and transformed every day so we can use the power of the sun to its full potential.

The energy which we receive from the Sun in the form of heat and light is called solar energy. It is the driver of everything from the Earth’s climate to all forms of life on the Earth. Since the ancient times, we have been using solar energy for our own use. However, the researchers feel that we are yet to optimally use the solar energy.

Use of Solar Energy in Ancient Era:

The ancient people known to have executed the utilization of solar energy on a substantial scale were the Ancient Egyptians, who utilized it to warm their homes. They structured and assembled their homes with the goal that the structures hid away the sun’s warmth amid the day and afterwards discharged it around evening time. Their building procedures kept their homes hotter during the evening, as well as controlled a cooler temperature inside on hot days. Romans and Native Americans both utilized comparable innovations to warm their homes using solar energy, and additionally different sorts of structures like Roman bathhouses.

In the third century B.C., the Greeks left a mark on the world not for utilizing solar energy for local solace, but rather, supposedly, as a weapon of mass destruction. As per the researchers, a Roman maritime power was cruising to remove the Greek bastion of Syracuse. With the assistance of the Archimedes, the inventor, the Greeks are accounted for to have utilized exceptionally cleaned metal shields as mirrors to enhance and centre the beams of the sun and set fire to the propelling boats.

Advantages of Solar Energy:

The major advantage of solar energy is that it is a renewable source. It is available to us as long as the Sun is present which is expected to be for another 5 billion years. Hence it can be used abundantly for the benefit of everyone.

Secondly, the use of solar energy can also help us reduce our electricity bills. Moreover, the use of solar energy can help us reduce our dependency on non-renewable sources of energy such as coal and petroleum. Also, solar energy can be utilized for different purposes. You can produce electricity as well as heat. Solar energy can be utilized to create power in regions without the requirement of an electricity grid.

Another advantage of solar energy is that it is a clean fuel. Use of solar energy does not cause any pollution and hence it is not harmful to the environment. Use of solar energy can help us reduce air pollution which for India, is a primary concern as on date. Also, India is a country having abundant sunlight all-round the year, hence, tapping of sunlight is not an issue. Of late, there has been an increase in the use of solar energy by the government as well as individuals. Efforts are on to reduce the setup costs of solar plants so as to help people move towards this clean and efficient fuel. Solar energy is the future of the country as it is the only energy which can help us overcome the environmental and energy-related issues our country has been facing since the last few years.

What is Solar Energy?

Solar energy is the energy contained in the sunlight in the form of photons. Life on earth is not possible without solar energy. All the microorganisms and single-celled organisms came into existence with the help of solar energy.

Plants have been using solar energy since the beginning. The leaves trap the solar energy and use it in the process of photosynthesis to prepare food. In this way, solar energy plays an essential role in the functioning of the food pyramid.

Solar energy is used by all the organisms, including both plants and animals. And human beings are no exceptions. First of all, the daylight brought in by the solar energy drives away the darkness and helps us finish all the chores easily.

Solar energy produces enough heat to dry out the washed clothes. It keeps us warm in the winters. Solar energy also plays an important role in diminishing the humidity and killing the harmful germs. Morning sunlight is known to strengthen our bones, improve our immunity, and help control many skin ailments.

On a larger level, solar energy has multiple other uses. For instance, concentrated solar power allows us to cook food. By converting the sunlight into accumulated solar energy, we can also produce electricity and charge our electrical devices.

Plus Points of Using Solar Energy:

But why prefer solar power when we have other sources of energy? The reasons are quite convincing actually. To begin with, the sun is a ball of fire. This fire is a result of the fusion reaction. That means, it is not going to burn out for millions of years to come.

Solar energy is a renewable form of energy which keeps getting replenished. So, it is safe to say that, depending on solar power would not deplete the earth of its natural resources. Moreover, using solar energy is an eco-friendly option for all of us, as it doesn’t cause any kind of pollution.

Solar energy offers as a great substitute to the other non-renewable resources, such as coal, wood, mineral oils, fossil fuels, etc. This puts a lesser load on the planet earth in various ways. Non-renewable sources are already getting exhausted at a rapid rate. They also cause pollution and hamper the life of all the living beings.

Most of all, meeting the needs with solar power also costs less. It is a cheaper and economical source of energy when compared to other conventional forms of energy. This is the reason why many developed countries are finally adopting a lifestyle based on solar power.

Methods to Use Solar Energy:

Solar energy can be trapped in several ways. One of the most effective technology is the use of solar power plants. These power plants are specifically designed for the purpose of electricity production on a larger level. Other appliances and technologies that work on solar energy are solar cookers, solar heaters, and solar cells. All these three types of solar appliances would be discussed one by one.

Starting with the solar cookers, these are the most revolutionary methods of cooking nowadays. Instead of using conventional fuels, such as gas, kerosene, or wood, solar cookers plainly work with the help of sunlight. These cookers have a glass lid which captures and concentrates all the sun rays to produce heat and cook food. Solar cookers are eco-friendly and economical means of cooking.

Solar heaters are the appliances that help in heating the water with solar energy. These devices work on the fluid-based technology. That means, either air or an anti-freezing fluid is put into the collector so that the water can be heated without any electricity.

The last and the third form is solar cells. These solar cells directly convert the solar light into electricity. Solar cells are especially popular in the areas where the supply from the power grid is less available. Many calculators, wrist watches, and similar systems work with this technology. Not only that, but the electricity produced by solar panels can also be stored in rechargeable solar batteries.

Solar energy is the future of the next generation. It is a safer, greener, and economical way of living life. It can be replenished and is a renewable source of energy which causes no pollution in the atmosphere. Solar energy also puts less burden on the other forms of non-renewable resources and protects the earth from various types of pollutions. As much as possible, we should all switch to using appliances based on solar power and save our planet earth.

Introduction:

Solar energy can simply be said to be the radiant heat and light that the sun produces and is harnessed through the use of a variety of technologies that are ever-evolving like photovoltaic, solar heating, solar architecture, thermal energy, artificial photosynthesis and power plants of molten salt. Solar energy is one very vital renewable energy source and the technologies of solar energy are widely categorized as either active solar or passive solar based on the manner of capture and distribution of the solar energy and how the solar energy is converted to solar power.

The techniques of active solar include using water heating that is solar, solar power that is concentrated and photovoltaic systems to harness solar energy. The techniques of passive solar include the design of space that will circulate air naturally, selection of materials that have light dispersing or thermal mass properties that are favourable and the orientation of a building towards the sun. Solar energy is a very appealing electricity source because solar energy is readily available in large magnitude. Research has shown that while the total consumption of energy all over the world annually is 559.8 EJ, the potential energy generation of solar energy is 1.575 EJ to 49,837 EJ which is a lot more than what is needed.

Potential of Solar Energy:

The potential of solar energy which can be used is quite different from the quantity of solar energy that is present close to the planet earth’s surface as a result of different factors like time variation, geography, available land and cloud cover, all limit the quantity of energy that can be acquired through solar sources.

The potential of solar energy is affected by geography because all the areas very close to equator get a greater quantity of radiation from the sun. The potential of solar energy can be greatly improved following the sun’s position through using photovoltaic in the areas that are not close to equator.

The potential of solar energy is affected by time variation because there is usually little or no solar radiation during the night on the earth’s surface that the solar panels can absorb. The potential of solar energy is also affected by cloud cover because incoming light can be blocked by clouds preventing it from reaching the earth’s surface from sun and this goes a long way in the reduction of the available light that solar cells can use.

The potential of solar energy is also affected by land availability because we can only set solar panels up for use on the land usually not in use and very suitable for the foxing of solar panels. It has been discovered that very suitable place to fix solar cells are roofs, since a lot of people have come to the realization that they also can directly collect energy from their houses through this means. We can also establish solar plants on areas of land which are not in use for business or other things.

Urban Planning and Architecture:

The design of buildings has been greatly influenced by sunlight ever since architectural history began. Methods of urban planning and solar architecture that is advanced were first used by the Chinese and Greeks; they made the orientation of the buildings they constructed to the south so that warmth and light can be provided.

Features of solar architecture like compact proportion ( ratio of surface area and volume), orientation, thermal mass and selective shading are all tailored to that particular environment and local climate so that spaces that are well can be produced and the building remains in a temperature range that is very comfortable. Ventilation systems, heating and solar lighting are all tied together in the solar design.

In the times of global warming and climate change as a result of the pollution of the atmosphere through the emission of smoke from the burning of fossil fuels, it is very important that alternative sources of energy that are renewable are gotten. Solar energy is one energy source that does not negatively affect the environment and cannot be exhausted.

When we develop solar energy and its technologies that are clean, inexhaustible and affordable, we are bound to enjoy benefits that are huge and long-term. Solar energy can go a very long way in increasing the energy security of a country as a result of reliance on inexhaustible, indigenous and largely non-import resource, reduce pollution, enhance sustainability, lower the prices of fossil fuels and lower the price and cost of curbing global warming. All of these advantages of solar energy are global.

Solar energy is basically energy from the sun and is received on earth and can be transformed into other forms of energy. Solar energy is usually used to generate electric or thermal energy. The sun provides energy that influences the climate on earth and enables the sustenance of all forms of life. It is a natural source of energy and is freely available. Research into solar energy has been done in attempts to discover methods of harvesting energy from the sun and utilizing it. Some forms of energy that are already in use are in existence due to the sun. An example is wind energy, which is derived from the wind yet in nature, wind develops due to the highs and lows in temperature. The sun plays a central role in terms of energy that is being used in the world.

Applications of Solar Energy:

In the modern world, there are important applications of solar energy that are being used. Applications of solar energy are both domestic and industrial. Domestic uses of solar energy do not require harvesting large amount of solar energy compared to the industrial uses. Domestic applications include solar cookers, solar hot water systems and air conditioners whereas industrial applications of solar energy include electricity production.

Solar cooking is one of the applications in which solar energy is harvested and redirected to produce heat energy for cooking purposes. Solar water heaters have become common application that is being used everywhere. Water heating systems have been designed such that they harvest heating energy from the sun. The same principles have been applied in air conditioning, space cooling and heating and in solar vehicles. There has been generation of electricity from solar energy that enables lighting and other functions.

With the constantly growing advancements in technology and industrialization, there will be increased discovery in the applications of solar energy. Solar energy can pretty much be important in everything it is just that we do not know how to apply it.

Solar energy has been used widely across the world and its importance has been realized. Solar energy is inexhaustible and renewable. Solar energy will never get depleted at any point in life and that is why it is an important source of energy in the world. The applications of solar energy continually use energy that is renewable without much struggle.

Solar energy is free of expenses because it is naturally acquired. The only costs incurred are those related to the applications and structuring. However, the cost of these equipment is lower compared to the cost of using other sources of energy.

Solar energy does not cause any form of environmental pollution. The process of generating solar energy does not involve any chemicals or products that may cause the pollution of the environment. It is a clean form of energy and its use promotes environmental cleanliness.

Due to the ease of availability of solar energy, it can be used in both rural and urban areas. In rural areas, people are usually challenged because installation of electricity is a problem but with the use of solar energy, most people have an access to electricity and saves on the cost.

Disadvantages of Solar Energy:

In as much as solar energy is important and advantageous, there are some factors that render it disadvantageous. One of those factors is the limitation to daytime use. Solar energy can only be maximized during the day because the sun shines at daytime. Also, the equipment used to harvest solar energy are expensive and delicate. Thee equipment include panels, solar collectors and solar cells. All these equipment are very delicate and require much care to avoid damaging them because the replacement costs are high.

Solar energy require large spaces to collect enough energy for use in various solar applications. The collection of solar energy has to cover a large area through the use of large solar panels, solar collectors and cells so that more adequate energy can be collected.

Solar energy is dependent on the sun and cannot be deployed where there is minimal sunshine. This means that solar energy is limited to areas with ample amounts of sun energy. During seasons like winter, the use of solar energy is totally impossible and therefore other forms of energy have to be sought.

Solar energy can never be an independent source of energy in the world. It is basically an alternative source of energy upon convenience i.e., during summer, specifically during the day. In your summer house you can opt to use solar energy and then use electricity during the rest of the seasons. For those countries who do not experience seasonal changes in climate, it is very convenient and it can be an independent source of energy for them.

The use of solar energy is specific to devices that do not consume large amounts of current e.g., in calculators.

Solar energy is an important source of energy. Advancements in technology has led to innovations of applications of solar energy that are of great help to human beings. It has been a great era of modern society whereby solar energy has been appreciated through its applications. The uses of solar energy are similar to those of other sources of energy. Everything has its pros and cons and solar energy is no different. The pros of solar energy outweigh the cons and that is why its use has been maintained over the years. However, the limitations of solar energy should not be ignored. These limitations are somehow disrupting the expansion of solar energy use in the world. It is important that solar energy is used widely as a form of energy because of its environmental-friendly characteristic. Other forms of energy especially fuels highly pollute the environment. Not only does saving the environment a priority in using solar energy but also the fact that solar energy is free, renewable and inexhaustible. What a great deal?

Solar Energy: Advantages and Disadvantages

Green technologies are dominating the global community’s discussion of sustainable energy generation. Renewable energy sources, with solar energy being one of the most feasible and affordable, are being supported and invested into by governments to instigate a new environment-friendly technology for sustainable energy (Iravani et al., 2017). One of the advantages of solar energy is its capacity to meet the demands of the whole world. As Figure 1 demonstrates, solar energy is dominating other sources of non-hydro renewable power in terms of capacity.

Besides, the Earth’s territory exposed to solar irradiation is extensive, with particular areas being the most potentially favorable for generating the most solar power. As Figure 2 demonstrates, these areas are marked with black dots.

The abundance of technologies available from solar energy generation allows for developing diverse approaches to sustainable power production. For example, photovoltaic solar energy technology is designed to utilize the capacity of a photovoltaic cell to generate electricity. Figure 3 demonstrates the principle of this technology, which is non-harmful to the environment.

As for the possible disadvantages of solar energy, one of them is the necessity to invest in the invention, development, and implementation of new technologies, which are currently lacking. In addition, the inconsistent distribution of solar irradiance across different continents might impose insufficiency in the solar energy supply.

Future Outlook

Solar energy has the potential to occupy a solid place in green technology due to its availability, affordability, and the advancement of research related to the alternative use of solar power for energy generation. One of the most significant contributions the use of solar power is likely to make is reducing climate change impact due to fossil fuel use (Creutzig et al., 2017). Moreover, the concept of solar cities seems to be realistic and feasible. This idea holds that urban areas might be transferred to complete use of renewable solar energy for electricity to eliminate the use of conventional plants (Byrne et al., 2017). Thus, solar energy is a promising alternative power source capable of shifting humanity toward green technology.
