Modern wind turbines have from one to four metal blades that operate at much higher rotor-tip speeds than windmills. Each blade is twisted like an airplane propeller.

Wind Energy | MIT Climate Portal

Wind energy is unique in how easily it can share land with other uses. In the U.S., around 90% of wind turbines are built on cropland or rangeland for grazing animals, most of it actively used. 9 In this sense, wind energy "takes up" hardly any land at all. Wind turbines can also be built offshore, sharing space with fishing and shipping.
