The only thing that's really improved is old node yields, but that's already a sunk cost. Each node continues to get more and more expensive which is why fewer and fewer companies can afford get chips made for them in that process. Leading edge stuff will almost always go to the most cutting edge node, which typically has lower yields. If you're trying to claim that reticle sizing has anything to do with it, that's not the case. Reticle sizing has stayed pretty much the same, wafer sizing is still basically the same. Semiwiki and semianalysis are great resources if you'd like to learn more

Reduce the market enough and make the regulatory burden high enough, and many companies will just say F it and stop making ICE altogether, while gubamint officials with their sweetheart back room deals for doing so will still gaslight everyone and say "wE nEvEr baNnEd AnyTHinG." This is the stage we're in now. Various levels of government are not "helping" anybody, they're helping themselves every step of the way.

Can be as good as 5% losses to as much as 15%, and depends a lot on cable length, wiring gauge, type of charger, rate, temperature, etc.

If people want to talk about how much energy is wasted when charging, refining crude is not an energy free operation either. As a start, about 24% of a standard 42 gallon barrel of crude is lost during refining. There are other energy costs like drilling, shipping, shipping the gasoline, electricity to pump the gasoline etc..
This is not to say it is more or less efficient. But if you want to point out energy loss when charging, you need to look at the energy expended to pump gas. It becomes a pretty complicated endeavor, so MPG and MPGe are used. |

All the effort to answer questions only to have that person vanish regarding their own questions being answered.
I once put this effort in on here. No more, personally. I've learned that changing people's minds is past difficult. Years of being called a nutter because I don't tow the popular, OFFICIAL, opinion. Welp, how'd all that turn out? I'll tell ya how...I was right. If you think about the word "useful" do you really want a personal attachment? So now I just shite post 97.2% of the time. But please carry on. Good info.

Basic physics. Heavier vehicles consume more energy, and that comes out in calculations such as these when you run through the math. The reason for the dishonesty is because then EV's wouldn't sell at all, and they wouldn't be able to gaslight people about how they're saving the environment when they're really not. To charge a 100 kWh battery, the grid itself has to consume 250-300 kWh worth of energy to produce that, and they pretend that's not the case with the MPGe number and hope you don't notice. ICE/hybrids are the most energy efficient vehicles on the road due to both the hybrid engines which are typically Atkinson cycle and hitting 40% peak thermal efficiency which matches the what the grid delivers, while not lugging around extremely heavy 1000+ lb battery packs everywhere they go. What you say about fuel production is true, and similar costs apply to battery production through mining hundreds of thousands of pounds of earth per battery, transporting that, refining it, processing it, etc. It's getting into the weeds and becomes impossible to calculate. Insiders who truly know the costs probably aren't allowed to tell.

Just to be clear, I am not endorsing EV or bashing ICE. Just pointing out that people are using energy loss as an argument against EVs and ignoring the energy loss for ICE, and why the complicated calculations for true energy usage necessitate MPG and MPGe as the benchmarks. IMO, EV is a great concept and one day it will make sense for all forms of road transportation. But in the near term, there are some significant growing pains. Lastly, both the rabid EV and ICE proponents obfuscate, manipulate statistics, and flat out lie. Then there are the people in the middle, like us, who have to live with the decisions. p.s. EVs will never replace the visceral feeling of a big boar V8, or a high revving V12, at WOT. |

Lastly, putting works in someone's mouth, yelling (yeah I know it is words but you get my point), and basically reducing the discussion to attacking/defending, is the reason people no longer have polite debates. So, well done, you have successfully driven me away from this conversation. You can continue to yell your opinion into a self reinforcing vacuum. |
