The Best Ways to Use Renewable Energy

Tidal Power (11/13)

The Rance tidal power plant uses the massive difference between low and high tide of the Atlantic. It is located on the estuary of the Rance River, in Bretagne, France. Special two-way turbines produce a maximum of 240 Megawatt (MW), about 4 percent of all energy consumed in the Bretagne. The plant, run by the French utility EDF, is the biggest in the world. A projected tidal power plant in South Korea could produce up to 250 MW. In most coastal areas, however, tidal power is not strong enough to efficiently produce energy. (Photo: EDF Médiathèque)
