Another point for nuclear, it actually works when it's not sunny and windy. Hot still days in the summer when everyone wants AC? No wind power. Terrible winter days that are super windy with no sun? Still no wind power because the wind is now too strong and will hurt the turbines, and no sun. Where's the heat coming from? Renewable sources are great, but the amount of storage they would need to be practical as a primary source of electricity is a bit prohibitive.
