Answer:
Hydropower (from Greek: ὕδωρ, "water"), also known as water power, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the kinetic energy of water into electrical or mechanical energy. Hydropower is a form of sustainable energy production.
