Strictly speaking EV batteries are not a fuel source, they are storage system.
I’ve lost track of the times that I have linked charts showing that the rapid ruse in atmospheric carbon dioxide can be linked to the start of the Industrial Revolution, and that in comparison to mankind’s relatively recent emmisions the contribution of volcanoes is again minuscule. Do you have a peer reviewed link to any papers that prove that this phase of global warming is not caused by the descendants from Maropeng 😂It seems that I have been under the mistaken belief that fossil fuel was not used in anyway to provide electric for EVs?
I agree with recycling etc, but climate change has hardly been caused by mankind as proved by scientists not on a government payroll! We may have contributed in a small way, but are not entirely responsible. After all did mankind promote the ice age, volcanoes, fire pits etc?
However I am happy for those that can afford EVs, the charging stations etc and good luck to them, but wish they would stop this holier than thou preaching. I will stick with my polluting diesel for the foreseeable future.

Where I disagree with Tobes is the idea that mankind has triggered climate change, The climate of our planet has been continually changing over the millenia, our climate is not a stable process, however historically it has had a fairly steady rate of change. Just as I was about to explain Otherclive's response above popped up. We have accelerated the rate of change and that has further destabilised the climates and ecologies abilities to moderate our intervention.
The last issue of offshore oil and gas licences pre 2 May 2024 didn’t succeed, neither did a previous issue of offshore wind licenses either. Industry needs certainty to invest.
And everyone is under the illusion that if we go ev, recycling etc. It will save us. Doubt it. Look at your super powers USA, China, Russia what are they doing, nowt, they won't stop with their fossil fuels. Have to remember we are just a small blot on this planet, and if we go 100% green it still won't save the world.
Back to my OP please.
Son says speed over 60 mph eats the battery. Quite significantly..
But using air con the whole 210 miles didn’t suck too much. Even on my diesel I’ve never really noticed a drop in mpg with ac. I suspect the modern ac is far more efficient than ten years ago. Heating is different.
Mine is residual heat otherwise wasted, his EV has to burn the battery,
The EV technology on the Volvo seems to be pessimistic in its calculations. Less chance of running out!
Here I am interested in long distances with EVs not round town which is clearly a different scenario.
Towing?
Twin or single motor? Sons is single . Unless you want to burn rubber single is ample . If the caravan came with a bank of batteries maybe longer tows may happen .

If you have the time just look on the internet at the changes made by China in the field of renewables and nuclear. Yes they still use too much coal but their carbon dioxide emission levels are now beginning to level out, an essential precondition before a reduction. They started their industrial development later than western nations did, so it’s not unexpected is it for them to want to catch up.

China’s CO2 emissions are set to fall in 2024 and could be facing structural decline, due to record growth in clean energy.
How China Became the World’s Leader on Renewable Energy
China has achieved stunning growth in its installed renewable capacity over the last two decades, far outpacing the rest of the world. But to end its continued dependence on fossil fuels, it must now move ahead with planned reforms to its national electricity system.

Yeah - speed is a huge part of drag, but goes up with the square, not linearly. This is partly why EV have so much focus on aerodynamic design. If you can minimise drag, you get more range from your limited (relative to fossil fuel) energy store.
The press have loved making a big deal about aircon, heating and headlights being significant users of energy. As you have noticed, they really are not. Especially with a well designed and insulated (for noise as well as heat) car, that uses a heat pump for heating the AC use is low. There is a display in the Volvo (Ask your so to show you the range assistant) that shows you the relative cost of driving vs climate control over the last 20,40 or 100 miles. Its just 1 or 2 percent.
Here you hit the nail on the head. In an EV, you can see where almost every Wh goes, and its to the drive train. In an ICE, the basic engine is _soooo_ inefficient by comparison (35% vs 95%) that one or two percent lost to cooling (heating is basically a side effect as you say) is lost in the noise.
Thats the Google bit - and yes, it is pesimistic - esp if you drive gently and stay below the speed limit. If you drive closer to the speed limit it's very accurate.
Of course - round town and local journeys you can basically ignore - after all you have a full range every single morning.
The single still haas a lot of get-up-and-go. the real difference is in towing capacity. In the XC40, the single motor is rated for 1500kg (same as my polestar). The twin is rated as 1800kg.
I am looking at the Polestar 4 as an option for my next, SM is 1500, twin motor 2000kg.
This is where things get interesting, but the tradeoffs get hard. A caravan with battery will be much heavier, but you can save weight on leisure battery and motor mover. But how does it charge, and how far can it help.
There are more and more caravan friendly EV chargers. The new Gridserve Winchester hub will have 4.
We don't make anything from the oil apart from tax revenue. The oil belongs the the oil companies not the UK. Unlike Norway who I believe have kept it all for the state.
Pure semantics. Without the oil or gas there would be no tax income from the companies or those employed by them. The companies profit by their activities which benefits shareholders, including pension and investment funds.
Either way in 2022-23 the Government received £9bn in direct tax revenues from the offshore companies. Not a profit?

This is at variance https://energyandcleanair.org/publi...nues-as-more-provinces-jump-on-the-bandwagon/
Someone somewhere isn’t telling all🙀
As ever both are valid in their respective information. My link did not ignore the construction of coal power stations and recognised that the central government needs to wrestle control from the provinces. Last bullet point on page 1 of the Carbon brief link. But they are cleaner stations and CG are looking on them as I back ups to the clean energy sources, which are moving on apace. There will then be a natural redundancy of old coal stations, followed hopefully by the newer ones. CG are also moving towards a national grid too, and nuclear installations are progressing.
So like any complex question there are numerous ways to view the solution.

If you say so.
£9bn is a pittance compared to what we would have got if the government of the day hadn't just licenced/given it away.
Norway has a huge positive sovereign wealth fund, we have debt instead.
Last year there was a 47% increase in the charging points, albeit with some regional disparities. But encouraging progress.

This excuse for not recycling and moving to renewables and low impact pollution processes in the UK is often to justify lethargy.
With such diverse processes across the globe, it's easy to claim an individual's activity won't make a difference, and that is largely true, but it's when all the little bits are put together, collective change both in the pollution results and in the mindsets of others can be seen.
Unfortunately for us, the people who are likely to benefit most from our small contributions now, will be our descendants. But equally our descendants are likely to suffer more if we don't change our bad habits.
Is that other peoples or your own?I am not aware that I have any bad habits except perhaps drinking too much beer.
Four months on I had an update from my son yesterday on the running costs and performance of his Volvo XC40 Recharge Dual Motor.
Harrogate to Bagshot Surrey needed two stops for charging . Total time 5 hours.
Bagshot to Cirencester required a third charge.
This journey illustrates the importance of planning an EV journey in advance. He was working all day in North Yorkshire friday , no time to charge at home, hence the two stops.
The first bank of superchargers at Chesterfield, had one broken ,one in use , he had the third 15 mins charge but at a very slow rate. Charger issue.
Just off M1/M40 junc, 20 mins
Final charge near me yesterday 25 mins took him to 80% £45.
This trip overall cost £100.It will cost him the same for the return journey!
Seems the average supercharger costs 89p per kWh.
His normal practice over the last four months has been home charging 90% .Office 10% (foc)
Home costs 7.9p per kWh.
If he had been fully charged prior to departure only one brief stop required. But the traffic and temperature were against him, lights on heater.
It seems the cost at a commercial supercharger is more than 10x than home! This makes the journey, this time , more expensive than an ICE. If HMG really want us all green by 2030 they really need to vastly improve the accessibility and costs of EV superchargers.
Overall the Volvo is well built , comfortable , very quick, but the range is no where near that stated. Nothing new there. Most ICEs don’t achieve the makers boast🤪
The lesson . Pre journey planning and domestic charging is essential.
Commercial super chargers are very expensive and clearly not well maintained and lacking in numbers.

Not forgetting the downtime spent recharging the vehicle which is a cost to the company.
It seems clear now that rapid charging, mid-journey, is marginally more expensive than petrol/diesel for an equivalent sized car. If this cost equivalence doesn't change, or EV ranges improve so that mid-journey charging isn't needed, then the full switch to EVs will never happen.
My fear is that government will achieve the switch by racking up fuel duty to ensure petrol/diesel is always more expensive than mid-journey charging.

I don't think marginally is the correct term when taking into account downtime. Not sure if I have done the maths correct, but someone earning about £30k a year, the cost to the company for 20 minutes down time could be about £4.76? Two or more stops a day over a 5 day week could impact the bottom line?
