The tiny kingdom of Bhutan, wedged into a Himalayan crevice between India and China, has experienced unprecedented growth in GDP -- an estimated eight percent between 2011 and 2012 and a projected 12.5 percent between 2012 and 2013, which makes it the world's fourth fastest-growing economy. This growth spurt is almost entirely thanks to the sale of hydropower to India, which accounted for 45 percent of the country’s revenue and 20 percent of its GDP in 2011. Flush with cash, the government plans to build ten new hydropower plants by 2020, bringing its total up to 40.
