Why Renewable Energy

1.1 Why Renewable Energy?

Electricity is necessity for day to day in our life. There are two ways of electricity generation either by non-conventional or conventional energy sources. Present day’s electrical energy is produced by the conventional energy resources like coal, diesel, and nuclear energy etc. The main drawback of these energy sources are it produce waste material like ash in thermal power station, nuclear radiation waste in nuclear power station and taking care of this wastage is very expensive and dangerous to the environment. This nuclear radiation waste is also very harmful to human being. The conventional energy resources are reducing day by day. Soon it will be completely dissolves from the earth so we have to search

There are many non-conventional energy resources like solar, wind, geothermal, tidal, etc. the tidal energy has drawbacks like it can only enforced on sea shores. While geothermal energy needs very lager step to extract heat from earth. Solar and wind are easily available in all condition. The non-conventional energy resources like solar, wind can be good alternative sources and they are reliable, pollution free and economical. Why renewable energy for India, because of the following the

The sun forms its energy through thermonuclear reactions that converts hydrogen to helium. This process creates electromagnetic radiation and heat energy. The electromagnetic radiation (in addition to infra-red light, visible light and ultra-violet radiation) streams out into space in all directions. The sun is a primary source of unlimited energy, most of which is wasted but produces us with hundreds of megawatts of power, keeps us pleasant and grows all our feed. Every day the sun showers earth with several million times as much energy as we used. To top it off, solar energy is safe, pollution-free power on and in which living things have bloomed since they first arose on earth. The history of solar energy is as old as humankind. In the last two centuries, we started using Sun's energy directly to produce electricity. In 1838, French scientist Alexandre Becquerel Edmond discovered that particular material produced little amount of electric current when exposed to light. It was not until 1946 that the photovoltaic cells (PV Cells) were patented by Sven Ason Berglund. 1954 has been stated the modern age of solar technology. This happened when the Bell Laboratories, while experimenting with semiconductors, discovered that the use of silicon could be more effective. It was a complete development, silicon set to function with certain impurities was actually extremely sensitive to light. In the 1954 the development of the Bell
