A Guide To Geothermal Energy

Maybe you've been hearing more about geothermal energy lately -- it gets mentioned more in the mix with solar and wind these days, especially when politicians are listing off, quickly as possible, all the forms of renewable energies they can think of. In case you don't know much about it, HuffPost Green has compiled this little FAQ.

What is geothermal energy?

Geothermal energy is a cheap and largely untapped natural energy resource. It's an intriguing sustainable energy source due to its unlimited supply, 24-hour availability and ability to decrease reliance on fossil fuels.

The EPA defines geothermal for us:

Geothermal energy is produced from the constant temperature of the earth. This can be accessed by drilling into the earth and extracting that heat and turning it into usable energy. Geothermal energy is an enormous underused resource that provides clean renewable energy in virtually unlimited supplies.
