  • Waves are caused by the wind blowing over the surface of the ocean. In many areas of the world, the wind blows with enough consistency and force to provide continuous waves. There is tremendous energy in the ocean waves. Wave power devices extract energy directly from the surface motion of ocean waves or from pressure fluctuations below the surface.

  • 1. Wave Energy Mary and Ellie (VIP)
  • 2. What is wave energy
    • To protect the environment for future generations it is vital that we move rapidly to a more sustainable lifestyle, reducing carbon emissions of greenhouse gases and consumption of limited resources.  Offshore wave energy has the potential to be one of the most environmentally benign forms of electricity generation with a minimal visual impact from the shore.
  • 3. How wave energy can be harnessed? The tide moves in and out twice a day. As it does it moves massive amounts of water and energy with it. This is a plentiful supply of energy but it is not that easy to convert it into electrical power for every day use.
  • 4. Were does the energy stored in waves come from?
    • The energy of the wave is stored in the movement of the wave. What happens is the energy in the wind gets transferred to the waves and that is how it works !!!!
  • 5. The advantages of wave energy
    • Waves are free and will not run out so the cost is in building the power station.
    • Wave power does not produce greenhouse gases.
    • There are very few safety risks with wave power generation.
  • 6. The disadvantages of wave energy
    • Waves can be big or small so you may not always be able to generate electricity.
    • You need to find a way of transporting the electricity from the sea onto the land.
    • Not many people have tried to generate electricity this way yet so the equipment is expensive.
  • 7. What causes wave energy
    • Waves are caused by the wind blowing over the surface of the ocean. In many areas of the world, the wind blows with enough consistency and force to provide continuous waves. There is tremendous energy in the ocean waves. Wave power devices extract energy directly from the surface motion of ocean waves or from pressure fluctuations below the
