Types of Renewable Energy Resources

Wind Power

 is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electricity, windmills for mechanical power, windpumps for water pumping or drainage, or sails to propel ships.

Wind power, as an alternative to fossil fuels, is plentiful, renewable, widely distributed, clean, and produces no greenhouse gas emissions during operation. A large wind farm may consist of several hundred individual wind turbines which are connected to the electric power transmission network. 

Solar Power

is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power(CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into electric current using the photoelectric effect.^[1]

Hydro Power

is power that is derived from the force or energy of moving water, which may be harnessed for useful purposes. Prior to the development of electric power, hydropower was used for irrigation, and operation of various machines, such aswatermills, textile machines, sawmills, dock cranes, and domestic lifts.

Geothermal Power

Technologies in use include dry steam power plants, flash steam power plants and binary cycle power plants. Geothermal electricity generation is currently used in 24 countries^[1] while geothermal heating is in use in 70 countries.^[2]

Bio fuel

is a type of fuel which is in some way derived from biomass. The term covers solid biomass, liquid fuels and various biogases.^[1]Biofuels are gaining increased public and scientific attention, driven by factors such as oil price spikes, the need for increased energy security, concern over greenhouse gas emissions from fossil fuels, and government subsidies.
