In Iceland, geothermal wells drilled in the three-kilometer volcano, which can provide an endless supply of Iceland environmentally clean electricity. From the deep well at two miles, they were drilled in active volcanic crater Krafla, will extract a supercritical water (a condition in which the difference between the liquid disappears and the gas phase). If they can 'tame' the liquid, that is, if it does not blow up their wells or not dissolve the steel pipe, and turn it into electricity, Iceland is ten times increase the amount of energy they take from the earth. The island - a big volcano, formed millions of years ago. Geological Evolution has made Iceland a good place to collect geothermal energy. Porous rock absorbs hundreds of millimeters of precipitation each year, and stirs them into the underground depths. Altavista has much experience in this field. Use this energy is not hard question is only as drill and bring the hot liquid to the surface to power.

Then, if the plant is working, as usual: steam turns a turbine, which drives a generator. More than 50 countries using geothermal energy, pretty much everywhere where magma and water stykayutsya within a few kilometers on the surface. Iceland takes 14th place in the world by the presence of geothermal resources, but at the same time, is the largest producer of energy per capita. Last fall, Iceland entered into a deep economic crisis. Now Icelanders save on everything, including energy. Many countries are now beginning to use renewable energy sources - mainly solar and wind - because they want to reduce the consumption of coal and oil. Iceland also started to introduce environmental technology, starting with the oil crisis of the 1970s, when it advanced people realize that their dependence on imported energy was weak point. After a decade and $ 22 million investment, the Icelandic Deep Drilling Project in the next month must successfully using supercritical water.
