Solar Energy
The energy derived directly or indirectly from the sun in the form of the solar radiation is termed as solar energy. Solar energy is a renewable source of energy i.e. it can be used again and again. Moreover the use of solar energy is an eco friendly process that is why it is an excellent alternative to fossil fuels now a day.
Sun is the source of the unlimited solar energy. More than half of the energy supplied by the sun to the earth is wasted but still we receive millions of kilowatts of power, which is required to keep us warm, and it helps us to cultivate our food.
Solar energy plays a vital function in producing a clean, reliable energy for the future point of view.
Now a day solar energy is vitally converted into electrical energy. Electrical energy is frequently generated by the burning of fossil fuels like coal, natural gas, and oil. By the combustion process of these fossil fuels a number of gases are released such as carbon dioxide, sulfur dioxide, and nitrogen oxide, these are responsible for the increment in the atmospheric pollution.
Every year there is production of 6 billion tons of carbon, just by the combustion of fossil fuels. Renewable source of energy, like solar energy, wind energy can facilitate to attain the rising energy demands and in the same time it will also help to reduce the pollution and to prevent the loose of the environment and public health.
Here are some reasons which make it clear that why the use of the solar energy is best for both i.e. for whole world as well as for an individual.
- Solar energy is a renewable source of energy i.e. it can be used again and again to fulfill the demand of energy required. According to the opinion of a number of scientists and industry experts, it is estimated that renewable energy sources, such as win energy hydropower energy and solar, can fulfill the energy demand of half of the world in the coming 50 years, yet seeing that the energy requirement is continuously increasing.
- Clean energy: In the case of solar energy if we calculate the emissions throughout the manufacturing, then the photovoltaic generation will generates less than 15 percent of the carbon dioxide from a conservative coal-fired power system. The use of solar energy is the best option to replace the use of traditional fossil fuel energy sources. Because solar energy use help to prevent the discharge of pollutants into the environment.
- Solar energy requires smaller amount natural resources as compare to the conventional energy sources. The use of solar energy from sunlight can replace the use of stored and non renewable source of energy in natural resources like coal, natural gas, and petroleum. According to the estimation of the energy industry researchers the amount of area necessary for photovoltaic (PV) cells to generate sufficient electricity so as to get together all U.S. power requirements is less than 60,000 square kilometers.
- If we all use to prefer the use of solar energy in place of non renewable source of energy like energy of fossils thus in such case we can decrease the emissions of CO2 by 4.3 million tons per year, which is comparable of removing 850,000 cars from the road.
