How does tidal energy work?
Tidal energy, also referred to as tidal power, is the energy obtained from the rise and fall of tides. As the tides rise and fall, a massive amount of water moves toward and then away from shore. Turbines that are placed in the path of this moving water spin as the water passes by. These spinning turbines are connected to generators that create electricity.
What is the source of tide energy?
Tidal energy’s source is a result of the effects of the sun and moon’s gravitational fields, combined with our planet’s rotation around its axis, which results in low and high tides. With this in mind, the power source of tidal energy is potentially renewable, whether we are talking about tidal barrages, stream generators, or the more recent technology, dynamic tidal power (DTP). Compared to nuclear reserves and fossil fuels, the sun and moon’s gravitational fields, as well as the Earth’s rotation around its axis, will not cease to exist any time soon.

How does a tidal power plant affect the environment?
As we know it, these facilities generate electricity with the use of tidal barrages that rely on ocean level manipulation, thus potentially having the same environmental effects as hydroelectric dams. Also, the turbine frames may potentially disrupt the natural movement of marine animals, and the construction of the whole plant may also disturb migration of fish. Nevertheless, technological solutions are now being developed to resolve these issues.

What are the red structures that sit perpendicular to the waves?
Attenuators – These bright red structures consist of a series of linked segments that sit perpendicular to the waves. They flex with the motion of the waves, harvesting the energy before it is sent to hydraulic pumps where conversion occurs. The Pelamis is a fine example; off the coast of Scotland, the snake-like structure takes advantage of the bigger waves further out at sea.
How does wind energy work?
How Wave Energy Works. The wind blows across the ocean, releasing kinetic energy into the surface layer to create waves. The stronger the wind, the higher the rigorous vertical motion of the waves, creating greater amounts of kinetic energy. The waves behave like a conveyor belt, carrying the energy along their surface to the shore.
What is a wave generator?
Wave Energy Generators (WEG) are power plants that, due to their nature, need to be close to the shoreline. Some locals and visitors fear they are an eyesore that spoils an otherwise beautiful panorama.
