Wind doesn’t really have an infinite supply either, like I’ve already said there’s plenty of places that don’t get windmill useful wind ever, and even in places that do the wind periodically goes away. And as for nukes spent fuel if we weren’t so silly we could get rid of it easily. People don’t like nuke plants because moron hippies can’t hear the word “nuclear” without thinking of “bomb”, they get built in countries that don’t let idiot hippies make decisions. One of the great ironies of the world is that the only country to ever be nuked gets nearly twice as much (by percentage) of its electricity from nuke plants as the country that nuked them.
The world will produce the same amount of wind next year and the year after until the Lord returns. All of our current electrical needs could be provided by capturing a tiny percent of what blows across this country. Study the supply of fissionable material and you'll be surprised at how little there is.
Public opinion counts and people don't like nukes but they love windpower.
