What's the Difference Between a Windmill and a Wind

Nov 10, 2020· Wind turbines are used to generate electricity from the spinning of the blades, rather than simply converting that spinning energy into more mechanical work, such as turning a mill or pumping water. "A wind turbine in the United States is around 280 feet (85 meters) tall, whereas the older windmill typically wouldn't top 80 feet (24 meters
