Total annual power consumption in the US with the current number of EVs is about 3.93 trillion KWh.

If demand were evenly distributed throughout the year (it's not, which makes the challenge bigger) we would be using about 10,767. GWh per day.
Total utility battery storage available is about 7.8 GWh.

We currently have storage capacity for .07% of our daily needs. That 7/100ths of a percent of a day's storage.
How many days storage do we need to cover the times when the sun isn't shining and the wind isn't blowing? Two days? A week? What will that look like when we're at 100% EVs? Ready for more rolling blackouts?
Just to get one day of storage at our current consumption rate we need to expand storage to 1,429 TIMES what we currently have. Where are all those batteries going to come from, the Energizer Bunny?
Keep in mind, that's with no additional EVs and that doesn't even address how many turbines and solar panels we'll need.
I suspect you could cover the entire state of Texas with panels and turbines and still not be generating enough power.
