only that it’s available and plentiful. Electricity generated by burning fossil fuels such as coal‚ oil and natural gas‚ emits carbon dioxide‚ nitrogen oxides and sulfur oxides -- gases scientists believe contribute to climate change. Solar thermal (heat) energy is a carbon-free‚ renewable alternative to the power we generate with fossil fuels like coal and gas. This isn’t a thing of the future‚ either. Between 1984 and 1991‚ the United States built nine such plants in California’s Mojave Desert

We all see the sun light every day‚ once you step outside on a hot day you fell its power and how destructive and life giving it is. Solar energy is the energy of the future‚ the main problem we have is making sure it is efficient and cheap. It seems that it would be simple to capture the sun’s rays and make electricity‚ but the material that “captures” the rays is very expensive due to it having to be a really pure material; if we use materials that are not as “pure” the electric current can’t go
Free Sun Light Electron
Solar Energy In 1839 Alexander Edmond Becquerel discovered the photovoltaic effect which explains how electricity can be generated from sunlight. He claimed that an electrode submerged in a conductive solution would create an electric current. ‘However even after much research and development subsequent to the discovery‚ photovoltaic power continued to be very inefficient a solar cell were used mainly for the purposes of measuring light. Solar energy is radiant light and

Advantages of Solar Energy in India Solar energy provides cost effective solutions to energy problems where there is no electricity at all. Some of the advantages of solar energy which makes it all the more suitable for India are as follows: No Pollution : Solar energy is environment friendly. Solar energy is non-polluting‚ clean‚ reliable and renewable source of electricity. It does not pollute the air by releasing harmful gases like carbon dioxide‚ nitrogen oxide and sulphur oxide. Solar energy does not

Cause/Effect: Solar Energy Solar radiation is an energy resource many times larger than mankind’s energy needs. Mankind has been able to capture/harness this energy resource‚ but only on a limited scale. Mankind has found that the use of the sun was quite useful. They used it to grow and dry crops‚ dry clothing‚ produce heat‚ and for light. The sun is a sphere‚ on the inside of the sun there is a continuous process of fusion in which hydrogen nuclei combine to from helium nuclei. There is less

Advantages Solar cells provide cost effective solutions to energy problems in places where there is no mains electricity. Solar cells are also totally silent and non-polluting. As they have no moving parts they require little maintenance and have a long lifetime. Compared to other renewable sources they also possess many advantages; wind and water power rely on turbines which are noisy‚ expensive and liable to breaking down. Rooftop power is a good way of supplying energy to a growing community
