Reykjavik Geothermal Power Plant

This is the newest of 5 power plants that Iceland uses to heat, power,
and sustain life in one of the harshest climates on the planet. At
it's peak, this plant will generate about 700 megawatts of fully
renerable energy. That's just over half the 1.21 gigawatts Marty McFly
used to power his Delorian in Back To The Future.
