Hydrpower

 Hydroelectricity or hydroelectricity refers to the transformation of energy from flowing water to electricity. It is called a source of green energy, since the sun continuously renews the water cycle. Historically, one of the first applications of hydro control, such as grinding rice, has been for mechanical milling. Modern hydroelectric projects today produce power using turbines and generators, where mechanical energy is produced as flowing water spins rotors on turbines. This turbine is attached to an electromagnetic motor, which as the turbine turns generates electricity. The hydropower plants can be divided into three sizes: large (> 30 MW), small (100 kW-30 MW) or micro (< 100 kW). Hydropower is the largest contributor to all renewable energy sources, accounting for 6.7% of the world's electricity generation. Further growth of this mature technology may be possible though cost-effective sites have already been developed in many countries. Hydropower is an abundant, low-cost (where applicable) power source, despite high upfront building costs. It is also a flexible and reliable electricity source compared to other renewable options, as it may be stored for use at a later date. Dammed reservoirs can also assist in flood management, have a safe source of water and can be used for recreational purposes.
