(Preamble requires some mention of eco-friendliness...)

Q: Which country produces the most geothermal energy?
F: Iceland.
A: The USA.

Ludicrous though it sounds, America produces more Gigawatts in geothermal energy than anywhere else. San Francisco has the largest 'dry steam bed' in the world, which chucks out about a gigawatt.

25% of Iceland's electricity comes from geothermal, and 74% from hydroelectric. The remaining 1% oil dependency goes on their ships, which they're soon to replace with hydrogen engines. They're so cool.

The energy is so inexpensive that in the wintertime, some sidewalks in Reykjavík and Akureyri are heated.

[quote[When Ingolfur Arnarson sighted land on the voyage which would make him the first settler in Iceland, he threw the pillars of his high seat overboard and relied on the gods to direct him to where he should settle. His slaves found them washed ashore in a bay where "smoke" rose out of the ground. Therefore they called it Reykjavik -"Smoky Bay". But the smoke after which Iceland's capital is named was not the result of a fire, but was rather steam rising from hot springs.[/quote]

Randomly enough the Philippines is the second largest producer of Geothermal Energy in the world. They're hoping that by 2008 (or possibly 2010) they will overtake the US as the largest producer.

From that last link, it looks like the USA are going to give them a run for their money!
Quote:
Under the American Jobs Creation Act of 2004, geothermal power companies are allowed to claim a "production tax credit" of 1.8 cents per kWh on electricity produced from geothermal resources. Finally, the limited environmental damage associated with geothermic energy pushed several states into mandating its use. As a result, a recent forecast of the US Department of Energy projects the addition of geothermal installations with generating capacity totaling 6.8 gigawatts by 2025, a 50% jump from today's levels in the USA alone.

According to Snopes, Dubya's home in Texas uses "an efficient geothermal heating and cooling system [...] a system which uses roughly a quarter of the energy of a conventional heater".

Furthermore:

Water used by the house is reclaimed, treated and reused


Al Gore on the other hand:

Quote:
[Gore's] residence consumes electricity at a rate of about 12 times the average for a typical house in Nashville.
