That’s an interesting statistic. Is there a ready reference to that?
And how about the cost benefit ratio of these wind mills?
Late reply - I do not have a link to that stat. I read it somewhere in the past - and as an electrical contractor who has installed many residential scale solar to medium scale utility solar systems - that info stuck in my mind. I did some math a few years back and that stat seemed realistic.
This website - https://weatherguardwind.com/how-much-does-wind-turbine-cost-worth-it/ - has some good info.
