I dunno. I see your point, but at the same time there's the opportunity cost to consider. We simply cannot currently generate enough renewable energy to cover all our energy needs, so if you are wasting power that could've been used for something more important, it's a waste regardless of the source of your energy. The more energy society demands, the more likely it becomes that some of it is generated by coal. And does it really matter which electrons are used for what at the end of the day?
