The operation of windmills also create more pollution due to the gas turbines being idled to produce power when the wind dies.
Fifteen, twenty years ago my local liberal newspaper decided to ‘do their part’ and put a windmill up at one of their regional offices - done to much fanfare and pride.
Six months later - after repairs and adjustments - the experiment ended quietly with not a mention in the paper. A friend who wrote for the paper asked me how much money I thought they were saving a month with their ‘free energy’.
I don’t remember my exact guess but it was many of dollars less than I actually thought based on the fact the question was being asked and the way it was asked. I low balled my guess and was way off. The truth was less - much less - less than a dollar a month. A few cents. And yeah because the paper owned their own presses they had people who could calculate the ‘savings’. The green windmill was quietly taken down with no public notice.
