| − | [http://www.renewableenergytechinfo.com Renewable Energy] is energy produced from resources that are regenerative or for all practical purposes cannot be depleted. Sources such the sun's rays and the wind, cannot be exhausted and for that reason called renewable. They cause fewer emissions and are avalable locally. Their use can, with a large extent, reduce chemical, radioactive and thermal pollution. They are a viable source of clean and limitless energy. These are the non-conventional sources of energy. The majority of the renewable sources of energy are fairly non-polluting and considered clean with the exception of biomass, a renewable source, is a major polluter indoors.

| − | Sources of renewable energy or non-conventional energy will be the sun, wind, agricultural residue, firewood and animal dung. Energy generated from the sun is known as solar energy. Energy derived from water is named hydroelectricity. Biomass is firewood, animal dung, biodegradable waste from cities and crop residue. It becomes a source of energy when it's burnt. Geothermal energy is energy derived from hot, dry rocks, magma, hot water springs and natural geysers. Ocean thermal is energy based on waves and tidal waves.

| − | In terms of renewable energy, the most powerful and useful will be the sun. The sun is accessible from sunrise to sunset and produces an unimaginable amount of energy each and everyday. What solar collectors do is always to harness the energy from the sun in the form of radiation to become usable forms of energy for example heat and electricity, Cells in particular converts solar energy into electricity. With technology being so advanced, solar cells are taken to a new level. There are recreational vehicles, cell phones and cars.

| − | Solar heating systems count on a source of bright light, a surface or liquid that will absorb light along with a storage device for the resulting heat generated. A greenhouse is a useful one of this effect. Solar heat is definitely the cheapest and most practical form of renewable energy in the world. Some practical uses are hot water heaters, ovens, cookers and warming.

| − | From times long, sometime ago, sailing ships been dependent on the energy of the wind depict oceans. Likewise wind energy seemed to be used to work windmills for pumping water. Today, wind power is being used as a clean source of electricity around the world. Wind farms, since they are often called can provide enough electricity for thousands of homes at a time. The power of wind is used to show turbines, which in turn is linked to an electrical generator as well as the gearbox inside the generator converts the vitality of the spinning turbine into electricity.
