Not sure what the point is of the graph. Transport is only part of the problem? I agree. Our grid continues to get cleaner and I think as the grid gets cleaner it helps most of the other sectors.

A lot of that "renewables" is hydro, and hydro is being actively dismantled, not expanded.

The problem is that when the grid gets 10% cleaner, but we add 50% to the load to support EV's, that's not progress. Take a grid with 1G watt, and runs 40% carbon, and 60% everything else. That's 400MW of carbon, 600MW of everything else. Reduce carbon by 10% and we are at 300MW and 700WM. Multiply both by 1.5 and you now have 450WM of carbon and 1050MW of everything else. That's more net carbon consumption.

As it is, most EV's charge at night when supply is mostly coal and natural gas. Adding more of them isn't reducing carbon fuel consumption, even with the grid getting "cleaner". Time of use is never discussed, but it matters.

The fact that many states are seeing brownouts and curtailment on hot days is a good indicator that there isn't enough supply already. Until they invent nighttime solar or make the wind blow 24/7, and make that happen everywhere so we all have good access to that power, it's going to be a problem. Adequate Battery storage is a long ways off, and competes for the scarce and environmentally damaging resources that is making EV's possible.

When they use clean energy.

2021 article U.S. was at 23% coal. EV still seems to win vs ICE when it comes to CO2 over the life of the vehicle, even when the grid is almost all coal.

Last night in California, arguably the green power capitol of the country, natural gas supply was 4 times more of the generation than renewables at 8:00 PM last night. 24.5Gw vs 6.1Gw. At 1:00 AM when some claim is the best time to charge, the ratio is nearly identical at 16.6/4.7.

Not all locations have solar or wind. Those CO2 over the lifespan formulas are useless when not taking into account time of day and actual location patterns. Absolutely garbage results really. No more useful than saying the average income in the US is $54K, so all policies and decisions about government taxes and subsequent resource allocation for every person in every location is calculated on that figure.

Thanks for saying that, it's a thing I'll never understand, hydro runs 24/7 with almost zero risk and it's full renewable, plus providing water reserve during summers for people and agriculture, yet still at least here, the guys complaining about cars smog and traffic while promoting 'green' evs are the same doing sit-ins screaming dumb slogans versus dams environmental flow mini plants construction (0.5/1 GW, small things), that use existing reservoirs and water that has to be provided to the valley river by law (and common sense)...
we're talking about a small turbine in a room like this one for every dam that has a normal hydro plant.. why not?!



yet huge spaces in the same zone for solar plants still rated at 0.5/1 gw that work only during the day are really good!

I thought this was very interesting technology

Koenigsegg Gemera's 600bhp camless engine works

By doing away with the camshaft and replacing it with a compact actuator above each tappet, the Freevalve system allows each valve to be individually controlled. They can be lifted as much or as little as the engine management dictates, for as long or as little as required, as early or as late in the cycle as required. Or not at all. And each can act differently from its neighbor.

I discovered an engine startup in the UK at the beginning of this year and now for the life of me I can't recover the web page. But to summarize, its a different form of an internal combustion engine that is some 80% efficient and runs on nearly any type of combustible fuel. It would be a great design for a electrical generator in my wet-dream serial hybrid I discussed above. In fact the designer (company) is proving it in large generator use cases.

When one considers the loss of transporting electricity over the power grid and into the BEV storage battery, a serial hybrid can be is just as efficient with the right engine powering the generator. Fossil fuel just makes for better on-board energy storage. It's energy density is ideal when safety and refueling points of view are considered.

The modern EV drivetrain is excellent and I'd say the electric motor, which is as old as ICE, really has not much room to gain either. The EV advancement really is the battery energy density vs. cost and longevity quest and charging infrastructure. I just don't think the magic battery we've been hearing about for the past 20 years is going to materialize any time soon and put into practice under the umbrella of affordability. The answer to me is make electricity on board with a better ICE that's not burdened with a mechanical connection to the drive wheels.

The problem is Govenment is now involved with dictating the architecture, and any form of ICE is clearly off the table. That's what happens when humans think they can control the Earth's climate; they get all stupid and believe in themselves as God-like.

I am really impressed with the manufacturing and efficiency gains of Tesla’s hairpin motor over the old winding method.

Amazing how the Brits have already forgotten that it was draconian EU rules that forced Brexit. Guess this time they are looking for a real butt whooping.

It's good that Brits,Hungary,Poland,Italy and some others now are challenging the authoritarian and unaccountable commands from the E. U bods, one presenting ongoing legal challenges
The whole shebang needs to be dis band ed and its not long before that day will come freeing Bel gium in particular from its over taxed tyranny.

Electric vehicles are known to perform sub-optimally in cold weather -- i.e. that's a loss of range and power. A new study has found similar adverse effects when EVs are subjected to scorching temperatures.

Auto blog Carscoops first reported that data science company Recurrent tested several EVs to "analyze the relationship between batteries and their range." Recurrent's data found that if temperatures rise over 100 degrees Fahrenheit, then the ranges of EVs diminish.

K Line, the operator of the car carrier ship involved in a serious North Sea fire casualty, has revealed there were 498 electric vehicles (EVs) on board.

The massive roll-on, roll-off ship ablaze off the Dutch coast is transporting 500 electric vehicles. The ship's total cargo is around 3,800 vehicles, some of which are BMWs and Mercedes.

The figure is far higher than first estimated and appears to raise the likelihood that a lithium-ion battery in an EV either caused the blaze on the ship (built 2013) or added to its severity.

According to K Line, there were 3,783 vehicles on board, all of them new, including the 498 EVs.

The consignment, loaded in Germany, was heading to the Far East via the Suez Canal.

I think one of the EV's battery packs spontaneously combusted...

Ford shares are down hard early in the Friday session, after the automaker said its push into electric vehicles could lose it $4.5 billion this year. To put it briefly, it looks like the price war started by Elon Musk and Tesla in the world of EVs has done damage to the competition...
