  • Hydroelectricity is electricity generated by hydropower, typically the production of electrical power through the use of the gravitational force of falling or flowing water. Traditionally, it has been the most widely used form of renewable energy. Once a hydroelectric complex is constructed, the project produces no direct waste, and has a considerably lower output level of the greenhouse gas carbon dioxide (CO 2 ) than comparable fossil-fuel-powered energy plants. Most hydroelectric power comes from the potential energy of dam water driving a water turbine and generator. The energy extracted from the water depends on the volume and on the difference in height between the source and the water's outflow. The amount of potential energy in water is proportional to the height difference. This form of energy may create less detrimental effects to the environment. However, damming of water has been shown to have its own negative effects.
