Using underwater turbines to power our cities
Posted on April, 17th 2014.
An underwater version of wind turbines, tidal turbines turn marine currents into electricity, offering a new source of carbon-free and renewable energy with significant potential.In Twenty Thousand Leagues Under the Sea, Jules Vernes ponders the incredible potential of the oceans and the possibility of using marine resources to produce electricity. Did he ever imagine that, two and a half centuries later, people would be building huge turbines under the sea?
Among the many ways of producing electricity, tidal turbines offer several advantages: electricity production can be estimated accurately because, although the power generated by marine currents is intermittent, it is extremely easy to predict. Equivalent-capacity tidal turbines are also smaller than wind turbines, and the output of a tidal turbine is much greater due to the density of water.
Tidal turbines: a promising new source of carbon-free, renewable energy.
