World countries' geothermal production

Here is a graph showing countries' geothermal production for the 2007-2010 period. Some countries are not listed which may be due to the fact that data is difficult to record on each individual's method of electricity production.

The United States come first producing 15200 GWh, followed by The Philippines with 10187 GWh and Indonesia with 7882GWh.
