Can Be Used For :

• Heat buildings, directly, through passive solar buildings

• Heat and cool air through use of solar chimneys

• Solar air conditioning

Wind Power :

• Fastest growing of renewable energy technologies

• Provide less than 0.5 percent of global energy

• Used by Windmills

Water Power :

• Hydroelectric energy is a term usually reserved for large-scale hydroelectric dams.

• Damnless hydro systems derive kinetic energy from rivers and oceans without using a dam.

Liquid Biofuel:

• Liquid biofuel is usually either a bioalcohol such as ethanol fuel or a bio-oil such as biodiesel and straight vegetable oil.

•Biodiesel can be used in modern diesel vehicles with little or no modification to the engine and can be made from waste and virgin vegetable and animal oil and fats (lipids).

Solid Biomass :

•Solid biomass is mostly commonly usually used directly as a combustible fuel, producing 10-20 MJ/kg of heat.

•Its forms and sources include wood fuel, the biogenic portion of municipal solid waste, or the unused portion of field crops.

Geothermal Energy:

•Geothermal energy is energy obtained by tapping the heat of the earth itself, usually from kilometers deep into the Earth's crust.

•Three types of power plants are used to generate power from geothermal energy: dry steam, flash, and binary.
