where will we get the juice for all these EVs?

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)

Unicorn farts.
The smart answer would actually be LFTRs, but we can't be allowed to have actual green energy.

Nuclear.

The batteries
Makes you wonder why the politicians keep incentivizing electric cars.....

Point a box fan, powered by a solar shield, in front of a wind turbine. Problem solved.

The libtards haven’t thought that far ahead.

Like most projects pushed by politicians, they'll worry about that later. We'll have an energy crisis, which is what they are hoping for, so they can pass more laws to solve the problem they caused (which will cause more unforeseen consequences, which will require more laws).

If there’s a demand for it someone will supply it
I’m sure the same thing was said about gas when they started mass producing vehicles

Hard to supply it when government bans you from doing so.

Something something buggy whip maker rabble rabble
FTR this is a legit question sidestepped by politicians and the treasonous media but some tards on here act like questioning EV’s (and the sudden push to drag them into usage) is akin to being Amish

Ok. Who will produce the roughly 76 billion kWh per month needed to makeup the shortfall EVs will create? And more importantly, how will they produce it?

Sadly everything is political today. But My question is one that will have to be addressed. We’re going to need at least an extra 76 billion kWh per month for this EV thing to work. It’s going to have to come from somewhere.

I don’t know
I’m not in that business, but it sounds like there’s lots of money to be made so I may look at some good companies to invest in

Wish in one hand and shite in the other and see which one fills up first.

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.
The larger issue is the grid infrastructure, not power generation.
As for the fuel source, natural gas would likely account for the bulk of it.
ETA: Another note for perspective.. the average utility-scale combined cycle gas turbine (CCGT) generator produces around 500 MW. Really big units can push 1,000 MW in some cases, and the larger Entergy gas plants have 1,500-2,000 MW capacities (from multiple generators).
So you’re talking about needing to add in the neighborhood of 3-5 generating units per state.

Well OP is not gonna like that.
