That means that about 120–175 wind turbines are required to replace a single generating unit.
How many windmills do we need?
That turns into about 3.3 terawatts (TW) of wind generation capacity. The average wind turbine installed in the USA in 2018 was 2.6 megawatts (MW) in capacity. If we were just going to install that scale of wind turbine, that means we would need about 1.26 million of them.
