It is a huge engineering challenge, and one which may usher in a new age of geothermal power production. Supercritical water can generate up to ten times more power than conventional geothermal sources. Follow the volcanoesThe embarrassment of geothermal riches on offer in Iceland is unusual, but by no means unique. Mexico and New Zealand trail at a little over 1,000 MW each, and Iceland (665 MW) comes in seventh behind Italy (916 MW). Iceland makes creative use of its unusual geology, with geothermal power used to maintain spas.
