Nuclear also needs to be paired with gas to meet demand shifts. I'm not sure why nuclear supporters are so oblivous to this fact, they constantly mention 'baseload' but it seems like they may have only a vague understanding of what that actually means. The non-baseload also needs to be generated somehow when people are awake and doing stuff.
So how do we reduce gas use the most, building $X Billion nuclear or $X Billion solar, wind and batteries? The expert consensus is the latter.
