Global warming -- Check my math/reasoning please.

It’s not the efficiency of the least-efficient plant that matters. It’s the efficiency of the marginal plant. These may or may not be the same thing. One can imagine a nation that still keeps an old, inefficient plant on their grid because it would cost even more to decommission it, but which would use plants of a more modern, efficient design if it became necessary to add more capacity.

I never looked at it from that angle. Thanks!
