Why is wave power a renewable resource?

Answer 1

Waves are produced by the shearing action of the wind blowing above the surface of the water body. Waves are considered as a renewable source of energy as they are an inexhaustible source of energy and have a high energy density. The energy density of waves close to the shore is about 20 kW/m of shore line whereas the energy density is about 60-80 kW/m off-shore (about 6-10 kms off-shore).

Devices such as the Oscillating Water Column, the Pelamis, the Clam, the Floating buoys are some of the devices that are used to derive energy from the waves.

Answer 2

because you can get waves again and again, so it is renewable

Answer 3

A renewable source is something that won't run out. Ocean waves don't run out, they're always there. E.g there isn't a limited number of waves.

Answer 4

Because by the evaporation/rainfall cycle, it is self-renewing.
