Hydropower

It is an energy source obtained from water flows or drops. Electricity is generated by allowing water to fall by gravity so that, as it passes through a turbine, it drives an electric generator.

It is considered a renewable energy source that depends on rainfall occurring in the upper sections of rivers before reaching the dams.

A distinction can be made between hydropower, which comes from large dams, and small hydropower, which is produced from small water drops and has an installed capacity of up to 10 MW.

Advantages

It is renewable, as the water used is returned to the riverbed.
It is a local energy source, which helps avoid imports from other countries.
It produces no pollution, as it generates no heat or harmful emissions.
It allows water to be stored for irrigation and other emergency uses.
Dams regulate river flow, preventing flooding in the lower sections of the river.
