Iceland may have fallen in the hole when the global recession hit, but the country could be soon emerging with one of the world’s largest energy sources. Iceland’s biggest energy company, Landsvirkjun, is planning on constructing the world’s longest underwater electric cable so that the country can sell its vast geothermal and volcanic energy to the rest of Europe. The sub-sea cable, if built, will have the potential to deliver as many as five terawatt-hours (5 billion kilowatt-hours) annually to the continent – this would be enough to power 1.25 million homes with clean energy.
