This photo is the steel reinforcement of the base of a wind turbine, you will still have to add between 21,000 and 28,000 cubic feet of concrete, which is a weight of nearly 2000 tons!
Once the wind turbine is dismantled, this base will forever be buried in the ground.
Then, of course, there is the sheer amount of space needed for pinwheels compared to a more rational and useful form of energy – like nuclear plants.
Nuclear plant: Approximately 1-4 square miles (640-2,560 acres)
Wind farm: Approximately 120-300 square miles (76,800-192,000 acres)
