This is bizarre. You're an expert because you've had solar water heating for 20+ years? Claim that in Asia and see how loud a laugh you get.
I'm suffering from confirmation bias but you can find a whole bunch of experts to back you up?
That IS confirmation bias, you picking and choosing which experts support you. During the Covid days, you could find a doctor that would sign a letter whatever you wanted for $100. But what were the medical associations saying?
When you get into the UN climate stuff you have thousands of experts in science and social sciences representing hundreds of countries all whittled down to one plan. I bet some of them have solar water heaters as well.
Dissolved, abraded more likely?
In tunnels, small particles also float away in the air...... And the rest washed away:

And there's lots of synthetic compounds mixed with rubber in the treads....
Average mileage per annum in UK is 8000. what's the savings then. Note my car is 15 years old and running fine so personally its already the cheapest transport out there so I've just not done the sums on newer models that depreciate like a brick.
And here is the interesting conundrum. If you are commuting and not lucky (so most people) you are spending a lot of time stuck in traffic or not even getting close to the speed limit. Is 2 tonnes of anything a sensible choice for this sort of driving. You want all the self driving aids, but you do not need a big car that needs lots of power (whatever the source). So a 2 car household should have one small light commuter and one full size car IF we are being logical surely?
Not any produce you eat directly. Crops can be used for ethanol or other biological reasons.
I read the quoted article. Mentions dust and dirt, not rubber particles. If there were rubber bits from the tires, why is there not a coating on not just the roadway but also on internal door frames, signage etc.
What do you think is the weight loss of a tire during the lifetime of use?
Have you ever seen a very old tire, that has been sitting around? Did it have cracks in it?
That would work if they could keep the runoff from areas fertilized with it from getting into other crops or groundwater.
It seems like someone good at math could calculate the rough volume of tire lost in a lifetime going from 11/32" tread depth to 3/32". Toyota Camry, tread width of 7.7" and diameter of 27.3". Figure on the low side 60% of that area is tread.
This site seems to have some information on tyre wear (and where the "dust" goes)

Significant time stuck in traffic favors EV's, no miles on the gas car but the engine is still idling and producing emissions. But yes, commuting cars should be smaller. If I lived in Europe where the drivers are generally better in my experience I would drive a very small commuter car.
Yes, 8k per year does reduce the benefit, although UK fuel prices are higher than US so the savings per mile goes up again. Assuming a 28 mpg gas car the per-year fuel price in the UK is around $1970, while the electricity (at UK home prices) is around $724 per year when using the low end of the Tesla's efficiency, so there you are still saving over 1200 per year.
People just need to be made better aware of the math - EV's are already cheaper than most new gas cars, especially right now that EV prices are getting more competitive and gas car prices have gone through some massive inflation.
Hi,
let's not forget, that -at least in germany- prices are driven artificially up.
We have very high energy costs here, because of various taxes and rates adding to the actual costs of kWh-generation (around 0.35€/kWh, while the average cost of a kWh at the stock exchange settles at 0.04€/kWh)
And though the price per kWh sunk considerably due to the renewable energies, the actual customers retail price is rising and rising.
Another example are the service costs.
My Renault dealer (got a ZOE) charges 100€/h for working on ICVs and 120€/h for working on EVs!!
They claim, that working on EVs requires special knowledge.
So yeah, that's right, but it also requires much less knowledge than for a ICV.
Think about those hundreds of parts and subassemblies like fuel injectors, clutches, pumps etc. that are not required any more.
Actually the service prices per hour should be less for EVs.
The receipt at the end is indeed cheaper, but just because so many hours of work time less.
But it should be even 20% or mor percent less!
Third example regards charging losses.
Charging my ZOE I have to add app. 20% of charging losses, due to the inefficient charger technology they implemented.
And it seems that most other manufacturers aren't much better in this regard.
Technology would easily allow to build chargers with only 5% or less loss.
Still though 'fuel consumption' costs me less than 5€/100km compared to >10€/100km for the Fiat Punto 1.4 I had before I went electric ... and won't ever go back

One plan? Really? All the nations on the planet are working to one plan, using the same implementation strategy?
The agreement is that we need to do something. That something should be done to get to net zero by 2050, that we need to end using fossil fuels domestically and commercially if we are to achieve it.
Nations have their own ideas and priorities, their own implementation strategy, their own experts. Who all disagree on how. Nuclear and GMOs being two such areas.
And it all has to be fitted in around 'events' like a war in Ukraine and a pandemic and individual nations domestic policy. All of that mediated through the interests of industry, activists and ultimately politicians who want to be elected next time round.
None of this is going to run smoothly.
As a case in point, after Fukushima Germany abandoned all nuclear because of popular demand. They had to reopen coal fired power stations and create at least one new open cast mine to feed it. They been banking on using Russian gas longer term...
Another. The EU has been strong on environmental issues, and a few weeks of farmer protests has seen chunks of it abandoned, including some measures to help reduce the co2 footprint of farming.
We've had an EV for the last four years, bought new. Now that we're retired, we don't do a lot of mileage - it's done about 20,000 miles. It's still on its first set of tyres. In other words, the tyres are lasting just as well as the tyres on any of the combustion cars we ever owned - probably better in fact. It's utterly ridiculous to suggest that non-existent excess tyre dust from our car has created more pollution than the emissions that would have been generated by 20,000 miles of a combusion engine. The lobbyists who generate these BS stories must be laughing.
Then take that weight and the miles driven per day to get how much dust that could produce. Pick a city like New York to multiply that by the cars and trucks per day.
The other approach would just to calculate the volume of tire wear per day times the number of tires per day.
Pretty sure the conclusion would be most of the tire loss is through sublimation not dust.
It was a friend who ran the Westinghouse tire wear facility some years back who first told me how tires wear. My question was what does breathing that do to your lungs? In a tunnel the auto exhaust mandates ventilation. Would that mandate change if all vehicles were electric? (Hint…No! But don’t tell Fox News, they would claim more ventilation is needed or some such nonsense, even though their argument is based on power generation and distribution!)

Exactly - like the Merc EQXX development car (see post 83) -- new, lightweight battery, lighter car, very low Cd, they concentrated on overall efficiency - getting over 1000km off of one charge.
I think you're willfully misconstruing his statement a bit. Had he said "one report" it would have been more obvious. Presumably he's referring to the UN's IPCC report on climate change, which is one massive report from over a thousand scientists and reviewed and approved by 195 countries. Obviously country by country responses to climate change are different - every country has different circumstances, and quite a few of them are as***** dictatorships that aren't doing jack about climate change, but they still all agreed as to the severity of climate change, which is the point- that there isn't some significant chunk of scientists saying, "oh maybe it isn't happening" or "maybe we don't need to do anything about it".
One area that needs to be tackled asap is Tesla's attacks on Right to Repair. Laws being tested in the US right now hopefully will produce the desired outcome of forcing third parties to be allowed to repair every aspect of Tesla's cars. For now they are fighting it and until we have RtR, Teslas will be stupidly expensive to repair. This will certainly continue to depress the attractiveness of used copies. As a side note I've seen Tesla's getting torn apart for repairs and of course many of us have watched the Sandy Munroe teardown videos and it's apparent to me as a shade tree mechanic that Tesla's are actually very easy to work on, and I could see a scenario where entire frame replacements would take a manageable length of time.
