3.  The first commercial power plant was built in 1911 in Italy  The first down hole heat exchanger was created in 1930  Binary Cycle developed in 1967 in Russia  Supplies approx 0.3% of the global electricity demand

4.  Worldwide commercial plants produce approx 10 GW of power ◦ Direct geothermal heating contributes an extra 28 GW  5 countries produce more than 15% of their electricity from geothermal sources ◦ Iceland, Philippines, El Salvador, Costa Rica, & Kenya  Plants use 3.5 square km per GW of electrical production versus 32 for coal  Environmentally safe ◦ No production of green house gasses

5.  Pipes are buried anywhere from 6-300ft underground  3.5-5 times more efficient than most fossil fuel furnaces  Polyethylene pipes used will last up to 50 years
