Chile has one of the longest coastlines in South America, making it a prime spot for wave energy. It has the world's driest desert, making it well suited for solar thermal. And it has 36 active volcanoes, making it a good candidate for geothermal. But the country has turned to a more destructive homegrown source of power: hydroelectricity. The $4 billion HidroAysen Project would construct five dams along the glacier-fed Baker and Pascua Rivers in remote Patagonia.rnTransporting electricity from the unpeopled wilderness to cities and industry in the north would require a continuous clearcut more than 300 feet wide and 1,500 miles long, some of it across national parkland.
