> Petroleum for transportation currently accounts for 27% of US energy usage
> 25% * 27% = 7% more electricity
There is no relation between amount of petroleum used and amount of electricity generated in the data provided by you. All you can say is we need the equivalent amount of 7% extra of total energy used today. You did not provide any data about how much of total energy used is electricity . If electricity is 7% of total energy usage, then we need 100% extra to charge all the cars.

There is.
> All you can say is we need the equivalent amount of 7% extra of total energy used today.
No.
We know how many BTU equivalent are used for electricity generation vs gasoline for transportation. And how much BTU equivalent is needed to power electric cars.
> TLDR: your math is wrong.
It probably is. Looks like transportation is 36% not 27% - that comes out to ~9% instead of ~7%.
> We know how many BTU equivalent are used for electricity generation vs gasoline for transportation. And how much BTU equivalent is needed to power electric cars.
Show us the data.
> There is.
There is literally no relation.
"Cars use 27% of total energy in US. And 25% of 27% is equal to 7% of electricity generated." HOW??
Unless you show us data on how much %age of total energy usage is electricity, there is no relation between the two!
According to some sources, electricity accounts for about 20% of total energy usage. So with your numbers, we would need extra 6.75% of total energy used. 6.75% of 20% is an extra 33.5% of electricity.
37.8q BTU electricity (~37% or ~18% depending on how you count loss).
27.5q BTU transportation (~27% OR ~36% depending on how you count loss).
You're assuming that ~60% of NEW electric generation will come from fossil fuels. We won't have a ~60% loss in electric generation from solar & wind - which is currently ~90% of NEW generation. In 5 years, coal & natural gas will likely drop to ~0% of NEW generation.
So you admit your original conclusion of "we only need 25% * 27% = 7% more electricity." is wrong?
If you take energy use used for transport (27.47), multiply it by 25% (because it's more efficient), you get 6.87. That's 18% of how much we generate in electricity today (37.75), not 7%.
What kind of linty clothes are you guys wearing? I have had usb-c phones for what seems like forever now.. Never had any issues or had to clean it even once.
Imagine your child taken away from you just on the basis of some assumptions. This makes my blood boil. I have never had murderous thoughts even when I have been wronged really bad. I just forget and move on with life. But I don't think I can do that if my child is taken from me for something I didn't do. I'll definitely go postal. Land of "Freedom".
I wish there was a viable alternative to everything Google (search, youtube, android, maps to name a few). I can't wait for Elon to buy Google and end this BS.
I think there is (for search at least, I may be biased), the question is are we ready to pay for it, or we expect the same business model as Google's (ad-tech) to somehow produce a better product for its users?
> Tesla, for example, is much more automated in many areas
By out-sourcing jobs to China.
> According to new figures released by the CPCA, Giga Shanghai was responsible for the production of 710,865 vehicles in 2022. And given Tesla sold 1,313,851 cars last year, that means 54.1 percent came from the Chinese plant
The closest I've seen to Tesla using more automation was just Musk spouting off random bullshit. Actual deep dives have shown that the automation tesla was trying to do isn't ready and they spent as long or longer fixing every car, often meaning they had lower output and more human involvement than competitors.
By what metric? The numbers I've seen indicates the opposite, although against European peers. But I don't know how reliable the numbers are, as the real data is probably a trade secret. The differences were really small however, and you might be able to slice them differently for a different result.
