They’re working on new technology

New generator technology

Your usage of “kWh per month” makes my head hurt.

Simplifying the math.. 75 kWh x 4.5 charges x 276 million vehicles = 129,375,000 kW = 129,375 MW.

Total utility-scale electrical generation capacity is 1,117,475 MW per the EIA with another 27,724 MW in small-scale solar generation.

In other words, we would need a ~10% increase to add an additional 130,000 MW generating capacity. Realistically you need more than that, because I assume the EIA data is peak capacity.

To put it into perspective, we added 260,000 MW of natural gas plus another 170,000 MW in renewable generating capacity between 2000 and 2020. So the generating capacity we added in the past 20 years is 3x more than what would be required by your math. Which means it’s definitely possible.

I’m sure the same thing was said about gas when they started mass producing vehicles


Gas was essentially a waste product prior to the automotive revolution.

Not much electricity capacity is sitting idle these days.

My son is 14 and smart. We were talking about picking a career so in demand they will still allow white males to do in the future.

One of my top suggestions was a career that involved making and moving electricity.

So you’re talking about needing to add in the neighborhood of 3-5 generating units per state.


Solid post with some great info. I do have some questions

1. Do we not get most of our natural gas from fracking? Like 2/3rd of it? To meet the extra demand that will require a lot of new fracking. Do you think the powers that be will allow it?

2. Getting approval for new power plants, is next to impossible. Environmentalists fight new power plants with endless lawsuits. Will there be the political will from the left to allow the construction of roughly 150 to 250 new power plants nationwide?

Nuclear would be the smart answer, but nobody wants nuclear. Energy prices will still be subject to oil prices, which means costs of EV recharging is going to fluctuate. It’s also going to cause just as much consumption of oil.

I inquired about Tesla solar roofing on the house we are building next year. Turns out it’s not available in the Baton Rouge area. It’s not even available in most of the country.

And I’m not putting those ugly panels on my roof. I have standards.

People are thinking about this and throwing billions at the energy sector right now. It’s never been easier for me to get capital for generation or infrastructure projects.

In 2019 there were only 229m licensed drivers in the US, LINK. Pretty big oversight in your breakdown assuming every registered car is driven an average of 1100 and whatever miles per month.

Maybe one day you’ll grow up and be a man. Until then you’re just a little boy. Deal with it kid.

They will figure that out later ……..

Two biggest EV issues :

Where will they get the lithium necessary ; and
How will they produce the energy necessary to charge the batteries

Thr thread about electric vehicles got me thinking. How much power will be required for all these electric cars? Here’s what I’ve found.

1. A standard EV battery requires 30 kWh per 100 miles LINK

2. A standard EVs range on a full charge is 250 miles. LINK

3. Thus, the average EV requires roughly 75 kWh for a full charge.

4. There are currently 276 million vehicles in the US. LINK

5. It will require a total of 20,700,000,000 kWh to charge that amount of vehicles once.

6. The most recent DOT statistics show men of all ages driving an average of 1,400 miles per month, and women driving an average of 850 miles per month. That averages out to 1,125 miles per month. LINK

7. Using these averages, we see the average EV will require 4.5 charges per month. That translates to a national total of 93,150,000,000 kWh per month.

8. In 2020, net generation of electricity from utility-scale generators in the United States was about 4,009 billion kilowatthours (kWh) (or about 4 trillion kWh). Divide that by 12 and you get 333,333,333,333 kWh generated in the US per month. LINK

9. Electricity consumption in the United States was about 3.8 trillion kilowatthours (kWh) in 2020. Divide that by 12 and you get a monthly average of 316,666,666,667 kWh usage. LINK

10. So right now we usually have roughly 17 billion in surplus kWh produced each month. But if we convert to all electric as many want us to do in the decade, it will require over 93 billion kWh per month. How will we fill this shortfall??


(And I did not even begin to consider the power requirements the over 2 million semi trucks will require)


And this is for one car per family?
Many in my neighborhood have 4 cars per family. I know one family that has 6. True they won't charge everyday but what would occur if 2 per family charged each evening/night?
