#TIDAL TURBINE GENERATOR#

They could cause collision damage, like wind turbines, however, with marine life, but the blades tend to move slowly so it isnвЂ™t that much of a concern. Tidal turbines are large, but they create relatively little disruption to the ecosystem around them. However, waterвЂ™s high density also means that tidal turbines need to be much stronger than wind turbines, making them more expensive to manufacture. Tidal turbines are able to produce much more electricity than wind power plants, mainly because water is much denser than air.

#TIDAL TURBINE GENERATOR#

The waterвЂ™s current pushes the blades of the turbine, which is connected to a generator that creates electricity. Tidal turbines are very similar to wind turbines, except they are below the waterвЂ™s surface instead of above or on land. There are three main ways to harness the energy created by tides and currents in a body of water: tidal turbines, tidal barrages, and tidal fences. Tides hold an incredible amount of energy, so much so that the National Renewable Energy Laboratory has estimated that the ocean has the potential to provide one-third of the electricity needed in the United States. Tidal power is only practical for large, commercial-scale projects. Tidal power is a clean and renewable energy source - it emits no greenhouse gases as it produces electricity. Tides fluctuate thanks to the gravitational pull of the sun and moon. The larger the tidal range, or the height difference between sea level at high and low tide, the more power can be produced. Tidal energy is a form of hydropower that works by harnessing the kinetic energy created from the rise and fall of ocean tides and currents, also called tidal flows, and turns it into usable electricity.
