I'm a big fan of solar and renewables, but at the same time, in the past there have been massive volcanic eruptions that have blocked out the sun for extended periods of time [1]. So in my mind, the post you were responding to makes a very good point.

I mentioned a few other too and as you say - the clue is in the name - renewables. Coal isn't renewable. The Carboniferous period only gifted us only so much to play with.
There have been some impressive sun blocks in the past but if, say, Yellowstone went off in a doomsday scenario, then we would not be worrying about electricity generation. It is far more likely that we (humanity as a whole) would be back in the stone age but with jolly refined language skills!
If we have all the other renewables available we do stand some sort of a chance of keeping going, despite a cataclysm.
I don't think that banking on coal n that is a good idea.
