What they don’t tell you is that they need to drill 300 feet deep in the bedrock for each windmill and that they also take fuel to operate. When they die - 10 years(?)- they don’t do anything to them but let them rot. They completely disrupt and destroy parts of the ecosystem all around including millions of seabirds.
Ten years is the max. I was associated (Pilot car) with a project in WV. Those were replaced after seven.
