I fear a pending nuclear disaster as old reactors are kept online to fulfill the power demands of an ill thought out policy!
Its all very well talking about Electric/Hydrogen cars to replace petrol, but energy supply has to go hand in hand with that policy. They're talking about increasing the number of charging stations, but nobody is talking about the power stations!

A upswell of renewable and backup energy generation will be taking place over the next decade
Ahh batteries, where the world will be picked clean of its rare metals only for it to be stockpiled by the rich and Chinese to create a false shortage and ensure price inflation.

EVs will be short lived as the world slowly realises they are a con and the batteries are not sustainable. Hydrogen is more likely to be the long term solution. I agree we need to get rid of ICEs, and quickly, but EVs are not the correct alternative!

Nissan Leaf has just completed the longest autonomous self drive of 230 miles in the UK. Marking a step forward to driverless vehicles being allowed in the UK

If they develop the hardware and software to adequate safety standards, then your self driving car will cost as much as a fighter jet! So they are either unaffordable or unsafe, either way a bad idea!
You can’t put electricity into a jerry can, carry it, and pour it in.
I thought it was comical that hundreds of thousands of cars running out.
The haters dont seem to recognise that when an EV is stood still it hardly using juice, motors aren't drawing any power.
heating systems work well, with instant heat, there is no waiting for the engine to warm up before warmth arrives. Like an ICE you would cycle the heating on/off. Also the heated seats, which is a very common feature with EVs are very frugal in energy for a nice warm backside.
Just one of the many luddite myths to try and justify, perpetuate ICE vehicles
We’re assuming it can be fully charged before the commuter dash. If at all. They won’t be allbe stuck on the roads...they could just be stuck at where ever the failed charge point is.
This is what will happen if we see a big uptake of electric source heating for homes and businesses.
A study showed that 20% uptake in heatpumps created a 14% increase in grid demand. On the assumption they are heatpumos operating in their normal mode (not in extra heat mode which uses significantly more electricity). Assume gas boilers are banned and eco incentives we could scale that uptake to 80% resulting in a 56% national increase in household electricity consumption!
And thats a increase and before plugging in the car or switching on the hob to fry an egg! What if it’s colder than usual? Climate change as you well know doesn’t mean it’s going to be warmer, we’ll see more regular temperatures extremes. So, it’s -5 degrees outside, the humid air has caused the air source heatpump to freeze up its evaporator fins so it has to switch to extra heat mode, which can be between 3 and 12kw depending on the size of the unit (mines 9Kw plus 2.5kw for the compressor). So let’s say that conservatively a heatpump in extra/auxiliary/emergency heat mode needs four times its usual power...400%. And let’s say 15% of household suffer this problem, that’s 15% using 400% which together means and total electric increase is now 60%
Plug some real number in here now...current average heat pump size is 1.7kw, current peak at 20% uptake creates a measure use increase of 7.5GW, at 80% it’s going to be 30GW on a cold day that can go up to 48GW...this is increase just for heating only remember. UK currently peaks just above 50GW, so we’re looking at 80GW, and beyond 98GW on a cold day! Our current outright ‘reliable’ maximum capacity is about 75GW which is not achievable as not all powerstations are able to be 100% online.
So as it is we don’t have enough ‘leccy to heat our homes if we turn off the gas and ban oil. Then we have to add transport and industry into it all....and of course, extra air conditioning for the hotter summers
I agree that the UK needs to up its grid capacity. All houses with south facing should be allowed to have Solar fitted. More turbines, God forbid -some nuclear, maybe better to buy from the French and let them have the headache of decommissioning.

Local history hat on: First fitted to a vehicle by a dude from down the Wrekin (who is also credited for the first electric self-propelled vehicle).

You forget its because they were stopped for hours, in some cases 10+, your not gonna try and claim a current generation EV will get anywhere near that with the heating on even flicking it on and off?
you seem to be totally blinkered to EV, ignore their limitations of the technology and facts about how bad they are for the environment. I don't think anyone will argue that in a few decades they will be the way to go, the problem is the current level of technology isn't at the stage of feasibly replacing petrol and diesel.
The scenario that given as an example is so rare its not even worth the concern. Some are using the farthest fetched doom scenarios to justify their hatred of EVs.
Ive never been stuck for more than an hour in all my 40 years of driving.
Yes the technology is now available. Ive proven to myself I can use a low end EV, do 100 miles every day and not be impeded at all. Savings galore in running, emissions, servicing
