Water can be used to drive directly.

The water in the rises and falls because of waves on the surface.
Wave machines use the energy in this movement to drive electrical generators.

Huge amounts of water move in and out of river mouths each day because of the .
A tidal barrage is a built over a river estuary to make use of the kinetic energy in the moving water.
The barrage contains electricity , which are driven by the water rushing through tubes in the barrage.

Hydroelectric power
Hydroelectric power stations use the kinetic energy in moving .
Often, the water comes from behind a dam built across a river valley.
The water high up behind the contains gravitational potential energy.
This is to kinetic energy as the water rushes down through tubes inside the dam.
The moving water drives generators.
