Waves are furious and strong

Waves can lift ships that weigh tonnes, break down solid dams and eat their way into slopes along the coast.

There is a lot of energy in waves and when about 70% of the Earth’s surface is covered by water, there is also a lot of space for them.

Wave energy can be used in wave power plants. This needs large technical machines. These are difficult to build as they must not be too heavy or expensive, but at the same time they must be able to withstand extreme weather.

The amount of energy in a wave is different in different places. There is a lot more energy in the waves in Hawaii than in Hornbæk.

The energy in the waves can be ‘harvested’ a long way out to sea or close to the shore. In Denmark, you have to go a long way out because it only slowly gets deep enough for big waves.

In Denmark, the use of wave energy is only at the research stage.
