Where did I dismiss renewables due to cost? I'm dismissing them due to inconvenience. For example consider how many solar panels need to be installed to replace a nuclear station, how much area will they cover, how many of them will need to be replaced every day, how a few non-sunny days in a row would render it useless, etc.

Nothing is "inconvenient" for a corporation. All "inconvenient" means is that they have to pay people to do it or put up with it. IOW, a cost.
