"Environmentalists in uproar as Iceland pays the price for green energy push
Europe's largest wilderness is paying the price of Iceland's decision to market cheap, "green", renewable electricity to the world, as a massive new smelter nears completion.
Across a pool of oily water deep inside a rocky cavern carved into a mountain, two steel pipes stretch up into a black void. They rise as high as the Empire State Building. Within weeks these pipes will be connected to enormous turbines and some 40km (25 miles) away, the waters of a 57 sq km reservoir will be released.
An hour's drive along the new asphalt road, which winds across a windswept plateau, you reach what was once one of the most isolated parts of an isolated country: Kárahnjúkar. The monochromatic scenery of black rock and white snow, under grey skies, was once dominated by a deep fissure in the earth - a canyon carved by the waters from Europe's largest glacier. Now that flow has dried to a trickle and this incredible natural feature is blocked by the massive concrete wall of a new dam.
For those building the Kárahnjúkar dam this marks an exciting new stage in the country's development. "The hydroelectric resources of Iceland are stranded here in the middle of the Atlantic Ocean," says Sigurdur Arnalds, an engineer from the national power company, Landsvirkjun.
"We cannot sell the power to other countries because we are isolated here. The sole purpose of this is to sell electrical power to foreign industries, in this case it's aluminium to Alcoa. If you look at it globally this is clean energy."
