(CNN) -- True or False: One of geothermal energy's biggest fans is U.S. President George W Bush who has a geothermal system installed in his Texas home
The answer is: TRUE
The President of the United States' Texas ranch is much more environmentally-friendly than his public stance on climate change would suggest. Bush's home, which is heated and cooled by a geothermal heating system, also sports solar panels and is so energy-efficient that it only uses 25% of the energy used by traditional heating and cooling systems.
