Question

what is hydroelectricity​

Answer 1

Answer:

Hydroelectricity is electricity made by generators that are pushed by the movement of water. It is usually made with dams that block a river to make a reservoir or collect water that is pumped there. When the water is released, the pressure behind the dam forces the water downpipes that lead to a turbine. This causes the turbine to turn, which turns a generator which makes electricity.

This renewable energy method makes about one sixth of the world's electricity. It produces less pollution than the fires of steam engines do. Some places such as Norway and Quebec get most of their electricity this way.

Answer 2

Answer:

Hydroelectric energy, also called hydroelectric power or hydroelectricity, is a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall—to generate electricity. People have used this force for millennia.
