Hydroelectricity - GCSE Physics Definition

Reviewed by: Caroline Carroll

Published

Hydroelectricity is a form of renewable energy that generates electricity by harnessing the kinetic energy of flowing water. It involves using a dam to control water flow from a river or reservoir, which then spins a turbine connected to a generator, converting mechanical energy into electrical energy. This method is highly efficient and does not produce direct carbon emissions once a hydroelectric dam is built, making it an environmentally friendly option. Although, the process of creating such dams can produce greenhouse gases and could damage local environments and habitats.
