Energy generated by using wind, tides, solar, geothermal heat, and biomass including farm and animal waste as well as human excreta is known as non-conventional energy. All these sources are renewable or inexhaustible and do not cause environmental pollution. More over they do not require heavy expenditure.

Wind Energy : Wind power is harnessed by setting up a windmill which is used for pumping water, grinding grain and generating electricity.

Thermal Power : onventional Energy. Conventional energysources includes oil, gas and coal. Theseconventional sources are usually fossil fuels. Their use leads to increased greenhouse gas emissions and other environmental damage

Solar Power : Sun is the source of all energy on the earth. It is most abundant, inexhaustible and universal source of energy


Nuclear power : Nuclear energy is the energy in the nucleus, or core, of an atom. Atoms are tiny units that make up all matter in the universe. Energy is what holds the nucleus together. There is a huge amount of power in an atoms dense nucleus

Hydro electricity  : Hydroelectricity is the term referring to electricity generated by hydropower; the production of electrical power through the use of the gravitational force of falling or flowing water. It is the most widely used form of renewable energy

Bio mass plant : Biomass refers to all plant material and animal excreta when considered as an energy source. Some important kinds of biomass are inferior wood, urban waste, bagasse, farm animal and human waste
