'''Hydroelectric power''' is a means of providing [[electricity]] from the forces of moving [[water]], and is the leading renewable [[energy]] source in the world. Hydropower plants account for about 24% of the world's power supply. <ref>http://people.howstuffworks.com/hydropower-plant.htm</ref> Hydroelectric power is seen both in large [[dam | dams]] and in "[[small hydro]]" projects that are much smaller in scale, and might serve just one commmunity. Larger hydroplants use dams to hold back water, creating a large [[reservoir]] of water, which is [[potential energy]]. The water becomes [[kinetic energy]] when a gate is opened, allowing the water to flow down and turn the blades of a [[turbine]], creating energy.
