The 18GW number comes from a report from the National Grid. The range was 6 to 18 GW if 100% of cars go electric by 2050. 6GW if charging is well managed and most charging is done off-peak and 18GW if charging is completely unmanaged. With the recent statement that future chargers will have off-peak charging programmed as the default it seems the UK is choosing the well managed option.
Where does the extra electricity come from? Maybe the UK just continues their current trend. UK energy consumption has been steadily falling since the mid-00's. By continuing to make other sectors of their economy more efficient they steady create excess capacity that can be used to charge EVs.
Or maybe nothing gets more efficient and we take the middle cause of 12 GW which is 20% of the current 60 GW. The UK would need to add 20% peak capacity over 28 years. That seems doable.

Agreed.
The 18 GW estimate however is just a guess. In reality it could be more.
I also doubt trucking and delivery vehicles are included in that number.
More than likely not.
The chart you posted is interesting. If I recall correctly. They started outsourcing more and more to Asia and India around that time.
Commercial
Online sales reduce the need for brick and mortar stores and Outsourcing business personnel reduces the need for office buildings.
Residential
Reduced or lost commercial and industrial jobs cause people to tighten the purse strings and conserve. Led lighting and more efficient appliances also helped to reduce.
Industrial
A reduction in electric use would seem obvious to see when one doesn’t produce as many products as in the past.
Well anyway, that’s what I see.
Then you need to add everything else to the electrical load that would be normally provided by other means of energy.
A near total electric society will consume more power than less.
In my opinion...
