Its literally impossible. By impossible I mean...impossible. There will likely not be even 1 new nuclear powerplant brought online by 2032. It took them 15 years just to CONSTRUCT the last reactor at Vogel in GA and it just recently got done. Get a new plant approved, permitted, surveyed, designed and built is likely a 20 plus year process due to Liberals like you and government red tape. Thats assuming you can EVER find a place to build one at all due to "Not in my backyard" attitudes...ESPECIALLY in blue states or anywhere near liberals. Again. Liberals are the problem...who could have ever guessed?



Nope. Not gonna happen period. I will settle for protecting the existing grid from attack. We need to get on that, yesterday.

I could maybe believe 2/3 of us cars being hybrids by then, but never pure EVs. The US is just too large and driving distances too vast to rely on transportation that requires constant recharging. Even if the US embarked on a crash program to build charging station, there is no way to build enough stations along the millions of miles of us highways and roads.
And ask the people in LA and Malibu just how practical EVs are right now.

I haven't done any long distance towing with my F-250 (7.3 gasser) yet so I'm curious to see what the differences are from my old 6.7 diesel. I'll find out in June.

I towed my center console to FT Lauderdale last spring and I think my mileage dropped from 16-14. My previous F150 with 5.0 got 16mpg w/o towing and like 12 with towing.

Energy is energy it doesn’t matter if it’s coming from a battery or stored in the distilled fluid from dino corpses. If your hypothetical ICE truck is consuming enough energy to only get 8 mpg then you’re going to be consuming the same energy sourced by a battery. That’s just an accounting problem in physics. Pulling big loads is going to require a really big battery. The tool for the job as you say!

And EVs actually impose an efficiency loss due to the resistance imparted by long transmission lines. If the energy is being generated hundreds of miles away, you lose the available energy with every single mile of wire.

I'll be interested to see whether you see the dramatic drop in fuel mileage I saw with my gasser.

I expect to see a drop, the question is how much.

I had an Excursion with the big V-10, I pulled our travel trailer and boat with it at various time. That V-10 would pass almost anything on the road while towing except a gas station.

Hey test that steering wheel lock position for me when you get a chance please! Apparently the wheel lock only engages when FORD is upside down?

@kiddiedoc is actually right on this one. The grid has gotten pretty good at managing transmission losses. That is why long transmission lines are such high voltages, to minimize the current flow which in turn minimizes the ohmic line losses.

And all of that heat generated by our ICE engines is waste heat and thus energy loss.

Does your steering wheel lock only engage when the wheel is rotated 180 degrees. IE the FORD on the wheel is upside down.

The other was do you get a seatbelt warning nanny for the passenger but blow that off. It’s against the law and I’m pretty sure any truck with a GVWR of 10000 lbs is exempt. I’ve read comments from owners of all three brands that they have no passenger seatbelt nanny.

Also read your manual if you want to turn off the driver nanny. You can actually do that.

I don’t get the seatbelt warning for the passenger side. I’ll check out the steering wheel lock.

ICEs in cars run somewhere between 20-40% efficiency (conversion of energy to power), while the remainder is lost primarily as heat. A small additional energy waste occurs with the transmission. Electric motors run around 85-90% efficiency.

Modern electrical transmission is quite efficient...90%+.

The biggest variable in overall efficiency/environmental impact actually occurs at the level of energy production. Coal is certainly the most wasteful and damaging, making EVs and ICEs nearly a wash, if electricity for charging is largely produced by it. Any cleaner form of production would heavily favor the EVs.

After some digging, I believe roughly 80% of electricity production in Tennessee is from nuclear, natural gas, and hydroelectric plants, leaving roughly 20% from coal, a number which continues to decline.

The biggest concern on BEVs I think is load on the grid. Especially with this datacenter and AI push. We need more nuke now

Ultimately I think hydrogen fuel cell is the final step.
