Non-conventional sources of power

Power generated by using wind, solar, biomass, tidal & geothermal heat 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.

Types of sources 

    1) Wind power

    2) Solar power

    3) Biomass power

    4) Tidal wave power

    5) Geo thermal power

1) Wind Power 

Wind power describes the process by which wind is used to generate electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. A generator can convert mechanical power into electricity.

2) Solar Power

Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics, indirectly using concentrated solar power, or a combination. Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam.

3) Biomass Power

Biomass power is carbon neutral electricity generated from renewable organic waste that would otherwise be dumped in landfills, openly burned, or left as fodder for forest fires. When burned, the energy in biomass is released as heat. Most biopower plants use direct-fired combustion systems. They burn biomass directly to produce high-pressure steam that drives a turbine generator to make electricity.

4) Tidal Wave power

Tidal wave power or tidal energy is the form of hydropower that converts the energy obtained from tides into useful forms of power, mainly electricity. Although not yet widely used, tidal energy has potential for future electricity generation. Tides are much more predictable than the wind and the sun.

5) Geothermal Power

Geothermal power is a form of renewable energy that taps into the heat emanating from the earth's core.geothermal power plant work by piping hot steam from underground reservoirs directly into turbines from geothermal reservoirs, which power the generators to provide electricity. ... The steam produced powers the turbines. The steam is cooled and condenses into water, where it is pumped back into the ground through the injection well.
