Alaska is getting geothermal. Modern estimates indicate that at least 25% of Alaska’s energy needs could be drawn from geothermal sources, including one active volcano, Mount Spurr. Accordingly, Alaska has begun surveys of the volcano and is leasing surrounding area to geothermal ventures.
If geothermal sources around the US were fully tapped, they could provide about 25% of the entire nation’s energy needs! Geothermal sources include hot springs and volcanoes, heat is extracted for use in creating steam to run electric generators. How exactly this is done, I’d like to know myself.
Some estimates claim 80% of the USA’s geothermal sources have yet to be discovered. (source)
