On an unrelated topic, what’s with all the “save energy during the eclipse” because of a decrease in solar energy on the grid?
I get that actual system operators will be facing a decrease and increase in solar power in a way they haven’t before, and that it will follow a path across the whole country, which means they’ll have to pay attention. What I don’t get is why this is a huge issue. Are there no cloudy days to contend with? No nights?

Am I missing something?
