Ever since 1973 oil crises, many countries have justifiably maintained an abiding interest in renewable energy sources and as a result many renewable energy programs were developed. Since then, research and development in the field were more promising and reliable. Main advantage of renewable energy is that its main ingredient is renewable and it plays crucial role in meeting environmental standards by combating global warming and other threats. At the current rate of energy consumption, the limited reserves of coal, oil, and gas may last only for 197, 40, and 56 years respectively.
The principle types of renewable energies available today are:
Solar energy
Hydro power
Wind power
Biomass energy
Municipal waste
Industrial waste
Wave energy
Tidal power
Geo thermal energy
