@ke7yxz Larger grids are good for evening out supply/demand, but building new transmission lines is very hard in the US. Some coverage of the issue:

And you can't average out the evening surge power demand. Batteries are getting cheaper but they're still $$$. Charging EVs during the day could help, especially for cars that sit around most of the day. But unfortunately it doesn't work for trucks in use during the day.
