I've been trying to figure out any kind of actual, real, intelligent justification for NOT diversifying our power generation capabilities as a nation. You know, trying to find the 'why' behind all the vitriol Republicans aim toward renewables. The advantages that come from advancing technology and spreading out the generation of electricity through as many channels as possible are enormous. And the disadvantages are .... well as far as I can tell there literally are NO disadvantages.
So unfortunately, I believe the only logical conclusion is the one you've drawn. What a sad reality.
