A group of turbines is called a wind power plant or a wind farm. Wind farms supply electrical energy to the utility grid so it can be widely distributed. Ranging in size and capacity, wind farms can easily be expanded to include additional turbines to meet growing electricity demands.

Locating wind farms takes careful planning. Many wind farms are located on land usually on rounded hills or open plains because there are no obstacles to reduce wind speed. Mountain valleys also work well because they funnel the wind. Some farms are even located off-shore to capitalize on coastal winds.
