Iceland is a cold country but under its surface there is boiling liquid rock. Iceland managed to live off earths natural energy source and today whole country’s electricity depends on it. Using Geothermal energy as energy source is clean renewable energy source, currently in U.S the project is being developed which would supply U.S for around 10% of its electricity. Iceland basically drilled down hot reservoirs under surface and use the steam that it produces to wind up turbines, which is then transferred into electricity. Geothermal Energy produces no greenhouse gases and is one of the cleanest renewable energy sources.
