Problems with wind turbines.
According to the Department of Energy, wind turbines generate electricity when the wind moves the fan blades, which are connected to an electric generator via a central shaft. As the blades turn, they turn the generator, creating an electri...
One often overlooked issue with wind turbines is they interfere with radar. That interference affects the accuracy of flight traffic control systems, weather services and defense operations, especially as wind farms become more common. One way to address this problem is to build turbine blades out of more radar-friendly materials.But winter also comes with a problem: freezing weather.
