Lesson Description:
Areas of the country that have an available coastline but are limited in other renewable resources can use the oceans to produce energy. We are familiar with the large hydroelectric dams that dot our nation, creating large reservoirs and flooding millions of acres of land. By turning to the restless seas we can find a source of energy that is not affected by clouds and the scarcity of wind. By using ocean power we can increase our need for power without having to deplete our existing non-renewable resources.

Ocean power is divided into three categories: wave energy, tidal energy, and ocean thermal energy conversion (OTEC) systems. It is estimated that two- to three-million megawatts of power could be produced on our world’s coastlines.

GEF's Ocean Power Activities Include:

• How can you put the energy of ocean tides to work?
• How does an OTEC plant work?
• Can water boil at room temperatures?
• Build a wave energy device.
