You only have to see the steam billowing from Iceland's naturally heated 'Blue Lagoon' to realise the potential geothermal energy has to provide more than enough heat in even the coldest of places.The 'Land of Fire and Ice' sits atop a plume of magma that lends itself perfectly to the exploitation of geothermal heat. This rather neglected renewable energy source has huge potential, and not just in Iceland. New technologies and growing demand makes geothermal power a possibility all across the world. At the moment, only 5% of global production potential is realised and the sector is growing by 10% each year.
