Wind turbine is a kind of turbine that uses wind energy as power. An Aerospace Research Institute in willbrahan, Massachusetts, has developed a wind turbine that costs half as much to generate electricity as a conventional turbine.

Wind turbines, the new design generates the same amount of electricity as traditional wind turbines, but the blades are only half the diameter of the latter. Smaller blade sizes and other factors allow new turbines to cluster more closely than traditional turbines, increasing power production per acre of land.
