Hydroelectricity works by harnessing the potential energy of flowing water. Gravity pulls water downstream, where it meets and turns the blades of a hydroelectric turbine. The turbine shaft turns the generator rotor, and that creates electricity in the same manner as with other electrical generators. While large hydroelectric plants that are part of a larger dam structure are common in the popular imagination, there are hydroelectric plants that use straight river flow and do not involve dams. Other models that are micro-generators and use ordinary streams to generate power.
