Energy is added when the Sun shines on the ocean, evaporating water from the surface that becomes water vapour and eventually forms clouds. This process gives the water a lot of potential energy due to its height.

When the water falls as rain on the mountains and is collected by dams, it is used to drive water turbines and generators to produce hydrolectricity.
