Common sense.  Lights on houses and factories don't shine with sunshine and dim on a cloudy day.  One word:  batteries.
Common sense.  If the windmills were as loud as jets flying around, ... you connect the dots.

I've been at the base of a windmill, surrounded by dozens of them.
The "constant sound of jets flying around in the sky" is a totally bull sh*t statement.  No sound remotely similar to even a single engine airplane can be heard.  
And that easily disproved lie is all I needed to read.  
Argue your case and convince people that your way is better.  If you lie and cheat, you're done.
