If we over react we get an unstable grid which is incredibly fragile and doesn't work in the winter. Just look at Germany today. The only country to voluntarily de-electrify itself.
My understanding is that they have actually added brown-coal capacity to their grid. The problem wasn't a fear of climate change, but of another Fukushima type event. They have been ramping up wind, and they have fairly reliable wind, but wind patterns can shift too.
