Intermittency Of Renewables?… Not So Much

51. You really have to start backing up what you say

"Remember, there are 200+ million registered light duty passenger vehicles in the US and at any given time and they are parked 20+ hours per day. You can play with the amount of available power at different penetrations of EVs and differing levels of participation to see what you come up with. For purposes of electric policy, as I recall, if 5% of an electric fleet is participating, any stability problems associated with a distributed generation grid is largely eliminated."

Ok, 5% of 460 million vehicles is 13 million...assume they all are top of the line 85 kwh Teslas that could cycle 4 times in a 20 hour period...that is 4.4 billion kwh.

Our nation uses 3,800 billion kwh a day.

So please explain to me how an energy sink that represents far less than 1% of our daily use makes this statement true:

"For purposes of electric policy, as I recall, if 5% of an electric fleet is participating, any stability problems associated with a distributed generation grid is largely eliminated."

You can't.

Heck, if you assume the entire vehicle fleet is electric, it still represents 2% of our energy use.

I don't think you have any idea of the scale of our electrical system...or any idea of how inefficient battery storage is. But you keep selling the snake oil.
