Yep, agree with all of that.
>Because EVs are here to save the car industry not the planet.
Especially this.
I've already made the point that EVs are almost like Rai Stones - an immobile indicator of wealth.
By buying a load more solar panels from China? :D
I'm talking about electrical transmission losses. The worst-case is for high-current, domestic loads, where about 15% of the power from the electrical power generator is lost. Add in another approx. 15% for charging and discharging the EV battery, and it's not so good.
>200Wh/km of wall socket power is about 60MJ per 100km
You forgot the above losses.
>A mostly-ff mix EV starts to look good here.
Not at all. By your (very optimistic) calculations, they are about the same. You'll never pay off the CO2 debt of manufacturing the EV battery, let alone start averting the climate catastrophe!
>Really to reduce emissions quickly in urban or suburban areas we need more vehicles that look like a Zev, an Aptera, suzuki samba, a golf cart or a bicycle etc. and fewer that resemble a tesla or a monster truck (as well as more rail based vehicles).
Very true. Weird that all of the currently-pushed solutions involve large and expensive EVs that barely do any good.
The sleight of hand is in the definition of "emissions".
If you mean CO2 - then no, not really. If you are powering your EV with a fossil-fuel powered grid, then the transmission and battery losses make up for the small gain in power plant efficiency over an ICE (as I already said). The CO2 argument for an EV only works when the grid has a substantial "green generation" component.
If you mean "emissions that are immediately bad for people" - it depends who you are talking about. EVs replace tailpipe emissions at the point of use with centralised emissions, both at the point of manufacture, and at the point of charging power generation (which will most likely be in a Western country with well-controlled emissions). As a cyclist, I have to admit it's nice not to breathe in tailpipe fumes. I try not to worry too much about all the damage being done by EV manufacture far far away from me.
Really? I look forward to heating my home with electricity this winter. All of those headlines of European countries facing blackouts, and record-high electricity prices, must be misinformation.
>China won’t go to Congo to “buy the state” and uses the Congo’s resources without the approval of the other members.
That's more or less how it works at the moment, and no-one cares. Why do you think a cartel of EV mineral producers would care, as it would contain approximately 0 Western countries?
The well-to-wheels analysis for an EV powered by a largely fossil-fuelled power grid is not good. Transmission and battery losses wipe out most of the (quite small) gains.
>a state like Utah in the US an ev becomes greener after the equivalent of few tens of gas tanks
Would love to see the source for that. Last time I checked, with a relatively "green" grid (something that almost everywhere in the US is a long way from achieving), the CO2 crossover point for an EV is at 20,000+ miles.
As such, EVs are very successful. They part people with large sums of money to keep economies moving, and limit how far they can travel, reducing CO2 emissions in the process.
In a way, they are like Rai Stones - expensive, immobile tokens of wealth.
Why? The OPEC cartel has the express purpose of controlling one particular commodity, to further their own political and economic ends.
>Russia aren’t included Why would they not be? Russia has the fourth-largest reserves of Nickel.
What would that number look like, if there were no EV mandate? After all, the first link you presented shows that the second-highest reason to buy an EV, at 34%, is "Rising penalty on ICE".
>dead set against them at any cost is dropping.
I'm dead set against owning one, but my choices will become ever-narrower (and, in time, practically zero).
Let's not pretend this is a free choice.
Regulations mandate features that would otherwise not necessarily be desirable, or purely economical. Let's not pretend otherwise, including EVs.
"Legacy auto will be caught short by the EV revolution!"
B*llox. EVs will be mandated, we will like them, and some will profit hugely.

Why are you surprised? China in particular has enormous reserves of coal (or at least, reportedly). How do you think all of that cheap but energy-intensive stuff we buy from China gets made?
