Wind Farms Turning a former waste site into a reliable source of renewable energy seems like a great idea—a real “win-win” for energy and the environment. Denmark has done just that with its Middelgrunden Wind Farm on a natural reef east of the Copenhagen harbor. Established in 2000 as the world’s largest offshore wind farm, it consists of 20 turbines with a total rated power of 40 Megawatts. For more than 200 years, the reef had been a dumping site for harbor sludge and other contaminated waste. Today, airline travelers flying into Copenhagen ...
