Thanks to its position on a volatile section of the Mid-Atlantic ridge, Iceland is a world leader in the the use of geothermal energy, and of the six geothermal power plants in Iceland, Hellisheiði (pronounced “het-li-shay-thee”) is the newest and largest. Fully operational since 2010, it sits on the mossy slopes of the Hengill volcano in the south-west of the country; a green and placid-looking landscape that belies the turbulent geological activity rumbling beneath it.
