Geothermal Power

Geothermal Power

Geothermal electricity is electricity generated from geothermal energy. Technologies in use include dry steam power plants, flash steam power plants and binary cycle power plants. Geothermal electricity generation is currently used in 24 countries, while geothermal heating is in use in 70 countries.

Estimates of the electricity generating potential of geothermal energy vary from 35 to 2,000 GW. Current worldwide installed capacity is 10,715 megawatts (MW), with the largest capacity in the United States (3,086 MW), Philippines, and Indonesia. India has announced a plan to develop the country's first geothermal power facility in Chhattisgarh.

Geothermal power is considered to be sustainable because the heat extraction is small compared with the Earth's heat content. The emission intensity of existing geothermal electric plants is on average 122 kg of CO
2 per megawatt-hour (MW·h) of electricity, about one-eighth of a conventional coal-fired plant.

Famous quotes containing the word power:

    If your friend has displeased you, you shall not sit down to consider it, for he has already lost all memory of the passage, and has doubled his power to serve you, and, ere you can rise up again, will burden you with blessings.
    Ralph Waldo Emerson (1803–1882)
