I realize that they're probably not common in the UK, but remote start is very common for ICE cars in the colder states

going out with an ice-scraper and a bit of pre-planning is more environmentally friendly. We don't have below 0 conditions that often in the uk.

Re 7 according to Gridwatch right now we are generating 40% of our demand by solar and wind. This number would be bigger if every wind asset was already connected to the grid.

Even if we accept the ridiculous use of ethanol in petrol or palm oil in diesel, 90% of the fuel used is fossil fuel.

I haven’t been checking regularly but there have been many times this year when renewables have made up 90% of demand. National Grid expect to have periods of 100% renewables by next year

Once storage is built at scale then this will be exponentially increased


40% is great but to turn that around just as the piss take did - that's 60% not great. I agree - 60% is an improvement on 100% not great,
but it is only an improvement .. EV users are still part of the problem

And how do the figures look if everyone switches from ICE to EV tomorrow.

in sweden it is fairly common, has been since electric locks etc

old school is fire on a shovel to get the machine warm enough to have fuel, oil and water that moves
first time we saw that was in scotland, we had a bit of a panic and scampered to "help" with the vehicle fire

even if it is a local tradition in cold places, it seems a bit edgy for my tastes

if the diesel is gloopy, choose the right ski wax makes sense to me

So are you suggesting that this is pointless? I'm not sure what you mean.

The facts are the facts, people do lots of stuff that is unnecessary; holidays, driving, buying loads of old shit etc.

To my mind anything that reduces the CO2 produced by any of them is a good thing.

I'd prefer that air travel was taxed properly, but it isn't. I therefore support any measure that makes it less damaging, we are within reach of commercial electric flight, sustainable aviation fuel (yeah I know) has been proven to save 36% of CO2 emissions on a NY to London flight:

https://corporate.virginatlantic.com/gb/en/media/press-releases/virgin-atlantic-flight100-saved-95-tonnes-of-co2.html

I live next door to a guy that is a pyromaniac, he has a huge bonfire every weekend, I don't know what he burns but really? It's mental, but as far as I know there's no law against it, and I'm not going to go down there and thump him.

Stuff should be mandated, just like ULEZ which has made a HUGE difference in London even though there are a huge number of people that oppose it:

https://www.theguardian.com/environment/2023/dec/28/london-ulez-averts-more-air-pollution-than-that-caused-by-capitals-airports-report-shows

More stuff needs to be mandated, government needs to mean what it says on insulation, and they need to be brave on charging polluters for their emissions.

I am concerned that some people will believe that if they make this one change in their lives, then they can carry on with everything else guilt free and point at others for the crisis we are facing. When people do not acknowledge that some of the power their vehicle is using still comes from fossil fuels, or ignore that they buy goods that are transported using diesel, if they don't understand that driving much less would also reduce emissions, that perhaps they should make an effort to drive less too, then it shows a naivety that tends to make me tune out about anything else they say on the subject.

But yes, generally any reduction is CO2 is a good thing. And yes, people do unnecessary emission make things - we all do. So yes this is part of the solution, but as I have said before I also think rewarding people who opt to use less could also be a useful tool.

So no, I don't think it is pointless, I just think we need to be honest about how good it is. There is a long way to go.

Early adopters are great, they pave the way for the rest of us. We need solutions for everyone though. So people are not penalised if they dont have a personal parking space to home charge from. Or own their own roof to general power off of etc. I want to see more EV public transport. etc.

I think all of us agree about needing to use more solar, wind and other really sustainable power, about long term insulation and less polluting vehicles etc. We probably disagree about how we get there and what we should do now.

Nicky, I totally agree with you that we all need to look at what we can do to pollute less as individuals and that the biggest polluters need more education. We don't drive anything like as much as we used to, and use a hybrid car as we weren't ready to go the whole way to electric,, nor could we get the sort of car we needed in electric. Investing in solar on the roof is a big investment, even if you own your own roof, and adding heat pump is going to add an awful lot more if you also have to have your house completely insulated.

As far as burning, I agree Tahir that your neighbour sounds a bit of a pyromaniac, but I think burning wood has its place. If we lose power, we can manage very well with candles and a wood fire; remember we went through the rolling power cuts of the 3 day week in the early 1970s. Using locally cut wood does use some fossil fuel, but with more electric chainsaws coming in, even that is reducing, so it is just electrifying the stage from wood through bringing it to be cut, cutting and splitting, and local delivery that needs electrifying. If the wood is left uncut it has other consequences such as loss of bird and insect life and a lot of the biodiversity loss in the UK is put down to lack of woodland management. I know this may be against some peoples ideas, but it is true. Open areas in woodland, glades, coppice areas etc. and particularly woodland edges are the richest in wildlife.

https://www.carsguide.com.au/car-news/the-electric-car-breakthrough-weve-all-been-waiting-for-gwm-is-close-to-developing-solid

sketchy on the detail. But it reminds me of what I have always said, that if people make a solid-state announcement like Toyota. e.g. we have solid-state but you won't see it for 4 years, then they are full of crap.
GWM is saying they have it and they will manufacture it in basically 6 months, that might not come true, but no one needs 4 years to do what they know how to do.

Interesting but I wouldn't call an increase in weight of 20kg 'miniscule'. Especially if the battery ever has to be changed (not very likely except long term I know) it could be the difference between manual and a hoist.

if only some of them work, ice has little argument it can make about range and longevity

if any of some can make the price attractive, tis another step forward

While remote start for ICE cars isn't rare here, it's not truly common either.
The reasons it's of consequence with EVs is that getting the car's cabin to the desired temp while still plugged in maintains more of the battery's potential range.

The trouble with wishing for the world to come around and congratulate you for using less and consuming less is primarily one of incentives. Why should they? And if they do, what shall they reward you with? More material goods or more money to buy more material goods?

(Yes, I agree that subsidizing low impact lifestyles could actually increase the adoption of them, but it's not exactly going to create a roaring national economy if it's successful, so what politician has incentive?)
