The last state I lived in had a failing grid because of a reliance on wind and solar, the state I'm in now has a failing grid due to wind and solar. The sun doesn't always shine, the wind doesn't always blow, and its all fun and games until your internet doesn't work, the water doesn't run, your AC isn't on in the summer, the heat doesn't work in the winter, and your hospitals start having outages (yes, seriously, its become a weekly occurrence); these are the literal effects I have seen first hand even in the richest places in the US, where policies have tried to accelerate wind and solar while ignoring existing infrastructure like natural gas and nuclear.
