Electricity generated by the flow of falling water, for example, dams. It is considered a Green Power, as this process does not emit carbon dioxide or nitrogen oxide.

Electricity generated using moving water

Harnessing energy from moving water e.g. rivers. Large scale hydro projects disrupt the environment and displace Iocal peoples; however, small scale or micro-hydro projects are a renewable and sustainable form of energy. Hydropower has been used for centuries for many mechanical tasks like grinding grain in mills, sawing wood, pumping water, and performing other labor-saving activities. In the 19th century, with the understanding of how to produce electric current from electro-magnetic principles, waterwheels began turning generators to produce electricity. Hydropower systems use the kinetic (motion) energy in flowing water to produce electricity or mechanical energy.
