Geothermal capacity

Geothermal energy
Geothermal power generation is a well established and relatively mature form of commercial renewable energy. One of its important characteristics is a high load factor, which means that each MW of capacity produces significantly more electricity during a year than a MW of wind or solar capacity

Geothermal capacity grew by 2.6% (290 MW) in 2012, to reach 11.4 GW. Most of the new capacity was added in the US (147 MW). Outside the US there were significant additions to capacity in Indonesia (130 MW) and Nicargua (72 MW). In Mexico the decommissioning of an old plant took 75 MW out of service.

Geothermal power runs at a much higher load factor than wind or solar (its source is continuous rather than intermittent), so geothermal produces significantly more electricity per MW of capacity. However the geological conditions required for geothermal power mean that development has been concentrated in a relatively small number of countries.

The US has the largest geothermal capacity, now just under 3.4 GW (29.6% of the world total), followed by the Philippines (2.0 GW), Indonesia (1.3 GW) and Mexico (0.8 GW).
