The word ‘hydro’ comes from the Greek word for ‘water’. Ancient Romans use hydroelectric energy through turbines for thousands of years. Water mills provide another source for hydroelectric energy.
The first U.S. hydroelectric power plant was built on the Fox River in 1882 in Appleton, Wisconsin. This plant powered two paper mills and one home. Hydroelectric energy comes from flowing water … winter and spring runoff from mountain streams and clear lakes. Water, when it is falling by the force of gravity, can be used to turn turbines and generators that produce electric energy.
