World’s biggest geothermal power plants

Geothermal electric plants will be our future source of electrical power the flows 24 hours a day and 7 days a week. There are a number of different ways of producing electricity from the earth's heat in these plants dry steam, flash steam and the most modern method binary cycle.
The following is a list of the largest geothermal plants currently in production, more details can be found in the article in the Energy Business Review.

1. The Geyser Geothermal Complex 1,517 MW, California.
2. Larderello Geothermal Complex 769MW, Italy
3. Cerro Pieto Geothermal Power Station 720MW, Mexico
4. Makban Geothermal Complex 4580MW, Philippines
5. Hellisheidi Geothermal Power Plant 303MW (40MW thermal energy), Iceland
6. Tiwi Geothermal Complex 289MW, Philippines
7. Malitbog Geothermal Power Station 232.5MW, Luzon Island
8. Wayang Windu Geothermal Power Plant 227MW Indonesia
9. Darajat Power Station 259MW Indonesia.

The thing to keep in mind is unlike hydroelectricity, which also has significant environmental impacts, geothermal plants are constantly expanding their capacity. Whereas hydro dams have diminished capacity over time and are prone to climate change impacts such as flash floods and drought.
