Very Cool: Geothermal Energy Works, No Drought, No Damage


From SPECTRA (by way of Forbes):

Geothermal energy comes from a mixture of water and steam under pressure drawn from nearly 2km beneath the earth. The pressure and heat separates water vapor from water when it rises to the surface which turns the turbines and produces electricity. ...

Hydroelectric energy generators can run at as little as 58% of their installed capacity.

Geothermal, however, consistently delivers almost full capacity. Geothermal sources currently account for one-third of Kenya’s installed capacity but provide more than half of the energy generated due to their high energy yield and stability against weather variations.

Kenya is looking to produce enough geothermal power by 2030, that as many as 150 million homes could be powered. That would require about 5,000 megawatts (MW) of geothermal energy. According to the Geothermal Energy Association in the United States, scientists say 42 million MW of power flow from the Earth’s interior, and will continue to do so for billions of years.

Twenty countries already use geothermal energy. The U.S. has 104 operating plants in nine states with a capacity of 3,700 MW. It's the leading geothermal energy producer in the world.

Do you think geothermal energy could supply power for the entire United States?
