Geothermal - Energy of the Future?

Geothermal energy has been around a long time. Systems today are much improved. New technologies have improved on many of the shortcomings of the past. New systems are very efficient now. Heat exchangers are sophisticated, efficient, and long lasting. The fans and fluid pumps used now are quiet and have long service lives. Some ground loops are made of high density polyethylene and have a life expectency of 200 years, and are warranted for 50 years. Geothermal systems have few moving parts, are low maintenance and give many years of trouble free service. Geothermal could be the energy of the future.
