I am sure there will be continual advancements in solar panel efficiencies and lowering of cost per watt. Solar is practical for powering most things.
We will always need to fire up the coal, oil, natural gas, nuclear, or hydro for smelting aluminum etc. From: Carl Peterson Sent: Friday, August 23, 2019 11:00 AM To: AnimalFarm Microwave Users Group Subject: Re: [AFMUG] Reselling Electricity Their must have been some other assumptions. Total usage is something like 10tw and average wind energy available under 100m is somewhere around 250tw. Obviously you could never capture all that energy.

Is there any chance that the increased wind caused by the windmills has led to an influx of mountain lions because their prey is easier to stalk? Somebody should look into this.

The wind from the windmills blows away the smell of predators which causes the mice and birds to come out. Its the mice and birds that attract the cats.
