If you step outside on a hot, sunny day, you’ll experience the power of the sun's heat and the light. That's solar energy. Solar energy is one of many renewable energy sources we can use. Renewableenergy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat which are renewable (naturally replaced). The more we use renewable energy, the more webenefit the environment, strengthen our energy security, create jobs locally, and help improve our economy. Sun is an important part of these energy sources. In fact, even though it might have somenegative effects, it is among the world's cleanest forms of energy.
Solar energy is renewable. We never have to worry about running out of sunlight or using it all up. The sun is a consistent powersource meaning it's always going to be there every day. Solar energy benefits the environment. Solar energy creates absolutely no pollution. This is perhaps the most important advantage that makes solarenergy so much more practical than oil. Oil burning releases harmful greenhouses gases, carcinogens and carbon dioxide into our precious air. Solar panels are extremely reliable. Solar cells make nonoise while collecting energy. There are no other renewable energy sources that are completely silent. In the long run, solar electricity is cheaper than buying it from the power company. Is very clearthat solar energy does not just benefit the environment but it also benefits your pocket.
There are many more advantages than disadvantages of solar energy, yet it is important to be familiarizedwith them too. One of the main disadvantages is the initial cost of the equipment used to get the suns energy. Though, you will save much more in a long term of time. A solar energy installation requiresa large area for the system to be efficient in providing a source of electricity. This may be a disadvantage in areas where space is short. Pollution can be a disadvantage to solar panels, as...
