Electricity Generation

The force of moving water is very powerful, and a hydroplant uses that force to generate electricity. Hydroplants are built near moving bodies of water such as rivers. Man-made facilities such as dams create moving water. The dams are built on reservoirs or lakes and have gates that can be opened or closed to control the water flowing over them.

The energy from hydropower changes as it flows through a hydroplant. The falling water begins as gravitational energy, and then converts to mechanical energy as the force of the water turns the turbine.

The generator connected to the turbine rotates, changing the mechanical energy to electrical energy. The transformers convert the electricity to usable voltage levels. The electricity is then sent through the transmission lines to distribution stations.

The use of hydropower is economical, helps conserve our fossil fuels, and is a clean, environmentally friendly source of energy.
