Current energy prices have given a boost to a long-used but often marginal form of energy: hot water. Specifically, hot water beneath the earth's surface. Geothermal. And several countries are moving to take advantage of whatever geothermal energy they may have. Leader in the field is Iceland, of course. Should have been named Steamland. Most homes there are heated by geothermally heated water.
Leader in the American geothermal field is Ormat, a publicly-owned company with almost 270,000 acres under lease. Most of this land is in the western U.S. Ormat went public last month, selling three million shares. The firm's based in Rano. Not that geothermal looks like that big a gamble right now.
You clever reader, you've been following along on the map and noted that most of this geothermal is found along the Pacific Ocean's infamous earthquake and fault-line zone that also produces all those Ring-of-Fire volcanoes.
Two more items of note: the world's most famous geothermal zone is NOT being developed. That would be Yellowstone National Park. One well just outside the park began to take water from the Mammoth Hot Springs underground resevoir there and was shut down.
