Iceland is another country enjoying great success with renewables. Nearly 100 percent of the country's electricity is now provided by geothermal and hydroelectric plants. In fact, Iceland generates the most clean electricity per person on Earth -- nearly nine time the European Union average. Iceland has taken a refreshingly straightforward approach to alternative energy by piping geothermal heat, via water, directly into 87 percent of homes.
It's estimated that using geothermal heat, instead of oil, has saved roughly eight billion dollars from 1970 to 2000, and lowered the country's carbon emissions by more than one third.
Albania and Paraguay have also converted almost entirely to renewable hydropower. Albania is home to eight major river systems, and Paraguay gets almost 100 percent of its electricity from the Itaipu Dam, nominated as one of the seven wonders of the modern world by the American Society of Civil Engineers.
