So what's so good about waves?

Waves are a natural way of sourcing energy, so we do not harm our environment or world when we are using electricity - for example; watching TV, charging devices, or even storing food in the fridge. They are a sustainable and renewable source, as the waves' energy is harvested, and then they flow back where they originally came from, creating more waves once more. Also, unlike other sources such as wind-power, this way of generating energy is available 24 hours a day, and every day.


How are the waves turned to energy?

The wave energy converter will convert the kinetic and potential energy in a wave to electrical energy. There are different versions of wave energy converters and they are positioned to face the opposite direction of the waves so they can catch and harness the energy. To sum up how some work, water pressurizes air when it enters through one opening of a tube, before the wave pulls away, and the pressure can be used to source energy. Another method is using a turbine that spins using the water coming in.

But how are waves made?

Waves are made when wind hits the surface of the water, causing friction, and that creates a ripple and swell in the water. This swell increases as water particles in the wave rotate, and forms a wave. The size and power of waves are influenced by the power of the wind, how long the wind has been blowing and how far the wave has travelled. Therefore, the best tidal power (wave energy) is harnessed when it is windy, and where the sea or ocean is large.
