For the past few decades, some doctors and anti-wind energy activists have used pseudoscience to suggest that wind turbine noise causes a slew of different health problems ranging from tinnitus and insomnia to birth defects and death.The bad news is that the capacity factors for wind power facilities are not very high. An unquestionable leader in wind power technology is Denmark – it’s a very windy country, and most of its wind power comes from off-shore wind farms. The best of those attain the capacity factor as high as 50%, and for all installations it reaches about 40%. Wind farms are also getting bigger. The largest wind farm in North America, Alta Wind Energy Center in California, which is the third largest in the world, will be small in comparison with the proposed 3-GW Chokecherry-Sierra Madre Wind Project in the U.S. or the proposed expansion of China’s 6-GW Gansu wind farm to a staggering 20-GW by 2020.According to Cedric Philibert, a renewable-energy expert at the International Energy Agency (IEA), conventional wind turbines in European waters could generate 2600–6000 TWhr per year, or 80–180% of current EU demand – but only at a cost of €55–70/MWhr.
