Geothermal power in Alaska February 28, 2008

Filed under: alternative, energy, environment — terra @ 7:00 am

Alaska has tapped into geothermal power. At a plant just north of Fairbanks, the water coming through a geyser is only 185 degrees, but it turns out that it’s hot enough to power a geothermal plant and “generates electricity, it heats the resort’s buildings, maintains a greenhouse and keeps an ice museum frozen year-round.” 

Heat stored beneath the Earth’s surface holds 50,000 times the energy of all the oil and gas in the world combined. If it could be harnessed, it would be an ideal source of base-load power: Geothermal is cleaner than fossil fuels, and more reliable than alternative sources like tidal, wind, wave and solar.

Unlike oil, which is not renewable, geothermal is predictable, renewable, and inexpensive. Unlike a coal plant, which takes a long time to build (and blow the tops off mountains), this geothermal plant was constructed and producing energy at 5 cents per kwh in less than 5 years. What are we waiting for?!
