Hydroelectric power (HEP)

Renewable energy developments include hydroelectric power and wind turbines. In a hydroelectric scheme, moving water drives turbines to generate electricity. Wind turbines use the movement of air.

Hydroelectric power (HEP) uses rivers to generate electricity. A dam holds back water to create a reservoir, which can flood extensive areas of rainforest. Submerged trees die, so forest is lost even where it has not first been felled.
