Mount Redoubt near Anchorage, Alaska looks as if it’s about to erupt. Photos and video of steam and a growing hole on the north side of the mountain remind us of the phenomenal power underneath the Earth’s crust. It’s looking likely that the volcano will blow, as heat and earthquake activity increase. The last blast took place in 1990, and an eruption in 1989 sent an ash cloud 150 miles.
The geothermal energy in this volcano must be tremendous, and it isn’t too far fetched to think about harnessing this power for energy. Recently a geothermal plant has been developed in Kilauea, Hawaii, and the Bonneville Power Administration estimates that there’s a 16,000 megawatt potential for the Newberry Caldera in Oregon.
