From what my son says a windmill is good for 8-10 years and you'll need 800 windmills to replace a reactor so do the math. Have you ever seen a windmill catch on fire? It's quite normal and it's a complete write-off. Not only that but they ruin the horizon where you could looks for miles.
Well that's progress Mark and not so free energy. the only good thing is when they catch on fire we could have a hell of a we-nee roast. and BBQ a few birds that pass by.
