Make waves and get the tide rolling on marine energy

Why support Marine Energy?

Marine energy involves harnessing the energy from the sea – including waves, tidal streams and tidal range – to generate clean, sustainable electricity.

Marine energy gives us the opportunity to:

  • Generate clean energy
  • Take action on climate change
  • Create jobs and skills in coastal communities
  • Play a part in the Green Recovery
  • Support a Welsh home grown industry

We want to demonstrate to politicians and decision makers that marine energy is supported by the public and that they should support it too.

Wave Energy

Waves are formed by winds blowing over the surface of the sea. The resultant movement of water carries kinetic energy which can be harnessed by wave energy devices. The best wave resources occur in areas where strong winds have travelled over long distances.

Tidal Energy

Since tides are predictable and reliable, with tide times varying according to location, tidal energy can offer a near continuous power supply. There are two main types of tidal energy:- tidal stream and tidal range.

Tidal stream energy makes use of the kinetic energy of moving water to power turbines. Tides never stop, with water moving first one way, then the other, the world over. Tidal stream technologies capture the kinetic energy of the currents flowing in and out of the tidal areas.

Tidal range energy makes use of the potential energy in the difference in height (or head) between high and low tides. Artificial tidal barrages or lagoons may be constructed to capture the tidal range.

Floating Offshore Wind (FLOW)

FLOW projects involve turbines mounted on floating structures tethered to the seabed. This means electricity can be generated in water depths where fixed-foundation turbines are not feasible but the wind speed is usually higher and more constant.
