Reply to comment by Surur in Electric world that kicks out fossil fuels will cost less than combustion economy. 30TW of wind and solar PV will take 0.2% of earth's surface. by DisasterousGiraffe

They're made to help the grid during peak hours (4-8 PM), not the entire night. Take a look at the chart.. It charges most of the day and outputs all of it's capacity by 8-9PM with peaks at most 3000 MW.

I am talking about voltage regulation, not supplying amps.

I'm talking about energy production, not voltage regulation. As more people own EV's and charge them at night, what do you think will be used at midnight for energy?

Not much energy as we will be sleeping?

If you are talking about charging cars, you would know they typically charge in the evening, not night, and that if our energy is mainly generated in the day, we could easily incentivise charging in the day also (e.g. by requiring chargers at parking spots).

People charge their EV's after midnight for better TOU rates. Just look at the graph and tell me batteries can supply energy for EV's after midnight.

I don't know about you, but in California utility rates are at least double during the evening compared to off peak hours (after midnight).

And that will obviously follow the availability of energy. If electricity is scarce at midnight then it will be expensive, and if it's most abundant in the day the incentive time will change.
