Overall, wind farms cost in the area of $1,000 per kW of capacity, so a wind farm consisting of seven 1.8-MW turbines runs about $12.6 million.
It can be plugged into the public grid, or used to supplement the power of a particular building or complex. Each Wind Tree is expected to cost â¬29,500 (US$36,500), but could pay for itself in a few years.The real advantage here is that cities could install âgrovesâ of Wind Trees at ground level to harvest power. The neat design could help avoid the public opposition that wind farms sometimes cause.t can be plugged into the public grid, or used to supplement the power of a particular building or complex.
