There is a fun podcast on this: https://www.bbc.co.uk/programmes/b092rbc0
The electric car bit is in the middle.
I think you'll like it as it does the whole stats thing.
The national grid paper is here:

Undoubtedly there are challenges, but the general feel, I get, is that none are insurmountable and the discussion is being driven by extremes.
On the rail what are the percentages of. 7% of rail out of goods from that port? Goods overall in the UK? I have no feel for this at all. It strikes me that Rail is very good in specific cases based on the goods and the locations, but not as flexible. |
The port rail thing is local to me & was in the news about more goods going by rail , so I read up on figures .The 7% by rail is total goods movements over the country as a whole , & road transport still does nearly 90% of it all .
With the EV charging , I have read up several of the FES being issued , & the most noticeable thing is they avoid the real issues .They will say things like the total yearly generation capacity is nearly enough for the average mileage done by some percentage of the motoring public .And if everybody has their smart meters to just charge when there is spare grid capacity , then it will not need a huge increase in generating capacity .
But the actual fact is , without a large increase in generation , if just 5% of the motoring public plug in at the same time in the Winter months , then the grid goes down , & will not restart without the load being removed .
