Determine the land area needed to develop a wind farm of 50-MW capacity using 2-MW wind turbines with 60 m blade length. Assume that sufficient wind resource is available to operate the turbines at rated power and the turbines must be spaced by seven times the blade length to avoid wake and turbulence.
