Ok, I didn’t read the article, but..
“You want to have a windmill to run a little community with 200 people...2 stores, a bar and a church...fine. But to run a city of 20,000 people. How stupid are they??”
Sure about that?
“the average turbine generates over 843,000 kWh per month—enough for more than 940 average U.S. homes.”
A typical wind farm includes many turbines.
Obviously, wind speed and energy storage capability affects delivery capacity at any given time.
We have a similar small community not far away. One commercial building and a few homes. There is a single windmill.
