Introduction
The world currently relies heavily on fossil fuels like coal, oil, and natural gas for its energy. These fuels are non-renewable; because they are extracted from finite resources that will eventually drop, becoming too expensive or too environmentally damaging to retrieve. In comparison, the renewable energy resources like wind and solar energy are constantly replenished and will never run out.

Sunlight is a major source for several renewable energies. The solar energy can be used for generating electricity, lighting and heating of both domestic and commercial purposes. The Sun’s heat steers the wind and these variations can be captured for energy generation with wind turbines. Again, sun and wind together causes the phenomenon of rain, which when flows downhill into rivers can be captures as hydroelectricity. The biomass obtained from the organic matter can be used to produce electricity, chemicals or fuels through the bioenergy. Hydrogen doesn’t occur as a gas in the environment. However, when separated from its compounds they can be burned as a fuel to produce electricity.

The internal heat of the Earth known as the geothermal energy can be used for electric power generation, and also the heating and cooling of buildings. The gravitational pull of the moon and the sun upon the Earth creates energy…
