Sorry but your facts are not correct if you yhink there is lots of spare capacity and that the grid is string enough to withstand the rise in demand for charging cars. MY17 D5 1st Edition Namib Orange
MY15 D4 HSE Kaikoura Stone
MY12 D4 HSE Nara Bronze Sold and gone
MY11 D4 HSE Stornaway Grey Sold and gone
D3 S spec Silver Sold and gone
Tow bar, full length roof bars, side steps, tow bar storage unit, surround camers.

If everyone knew what the state of our electrical networks had become you would all cringe. Russell is correct in what his saying I’m afraid. It’s now policy on our local DNO to leave faults on the cables and only repair if customers go off supply.
It’s now policy to back feed into a known fault and let it burn itself out until someone goes off supply. You can not go to any linkbox without there being fuses/links installed due to ongoing faults.
The network has never been in such a poor state of repair.
Why?
It’s all down to the foreign investors wanting the largest profit possible.
Many of the cables are 1930 cables, which are honestly in a better state than the 1970 cables, but are running at full capacity already. You can not just keep adding lengths to existing cables thinking it will all work.
In highly populated towns the cables have so many joints on them that you have to dig long trenches to find a suitable section of cable to branch joint a new service on to it for say a new charging point.
If we then need multiple charging points in the street I’m not sure it’s going to be physically possible in certain areas.
Everything is achievable but not without a lot of the infrastructure being changed at a very large cost.

Is this similar to what took the power off line in South America recently?

If sections of the M4 have a permanent speed limit below 70 mph should it be downgraded from a Motorway ?? .

The M4 around Port Talbot has had a 50mph limit for as long as I can remember ...around Newport, as the western M25, you'd be lucky to do over 50 most days. 21 year LR veteran > D2 GS 2003 > D3 S 2006 > D3 HSE 2009 > D4 HSE 2013 > D4 HSE 2015 > D5 HSE 2018 > DS HSE R-Dynamic P300e 2021

Well, I know nothing about the national grid, nor the science behind EVs. Neither, IMO, do any of us truly know the impact of human activity on the environment. as a colleague once said to me (a scientist at a pharma company) "It's a very arrogant person who believes that the human race is able to take on Mother Nature and alter her course"
But, answer me this. If EVs are so clean, who accounts for the pollution in generating the electricity? It has to come from somewhere. Renewables are still scarce and also come with an envirnmental impact of manufacturing the kit in the first place.
Who accounts for all the pollution caused by the production of Lithium batteries? Mining, transport, manufacturing and ultimately recycling.
Are EVs any less polluting to manufacture than a petrol or diesel car?
I don't pretend to know the answers but having specific limits to improve air quality in a specific area does seem rather futile to me.

If a reduction in maximum permitted speed from 70 mph to 50 mph produces an improvement in air quality, then we might assume that a reduction from 50 mph to 30 mph will also produce a similar improvement, and so on.

Surely not! Every Government since Thatcher has told us how privatisation increases investment, blah, blah etc. Surely these fine people wouldn't have been lying to us all these years... Visiting from rrsport.co.uk

Electric cars will break the current DNO network one of the reasons being the diversity applied at the network design stage which in the network design document assumes a load of around 4KVA per property depending on the type of heating (gas / electric) used.
It's not rocket science to see that with the push for a reduction in the use of fossil fuels and greater use of electric that 4KVA will be insufficient to meet the demand needed in all homes even before taking into account what is needed for charging the 2, 3 or more cars most households have
Had to call the DNO out to a service head fault recently and was talking to the 2 lads about the electric car charging loads that came out to sort it. The previous evening there had been a power outage locally which was down to a cable burn out because of an overload on one of the phases which needed a full replacement of the cable with roads closed and generators supplying temporary power to a number of homes and businesses while it was done, they were saying that the whole area would struggle with the extra loads of car charging as the network cabling was well undersized and this fault was likely to occur more often.
The problem is most network cabling was installed 60 - 90 years ago long before the electrical gadget revolution so any extra capacity built in at design has long since been used up "Never keep up with the Joneses. Drag'em down to your level. It's cheaper".

In addition, induction hobs to replace fossil fuels, electric heating etc...i agree the electricity network cant cope and renewable are only so good, in themselves shunting environmental impact - we need to find a new way

Isn't there a scheduling issue with network loads? If one has an EV, charging overnight when the rest of the house is "switched off" would seem sensible. I like the Tesla idea of PV on the roof charging a battery box which is then used to charge the car initially, the rest of the car's battery being filled by overnight network charging.
If people want to run their ovens, power showers, devices, and charge the car at the same time, then there needs to be investment. That will come with bigger bills.
Of course, we need to sort the power source too. Renewables can do a lot - we have a huge wind and tidal potential for an island such as ours. But it needs, you guessed it, major investment. Visiting from rrsport.co.uk

I don't get this reduction in speed to improve air quality.
Surely if you are going slower you are longer in the area and in a lower gear so giving more revs and exhaust emissions, am I right ?
