This site gives a good insight to the UK national grid showing electricity demand and where it is coming from:-
http://www.gridwatch.templar.co.uk/
Current demand is about 35 GW (GW = gigawatts = 10 to the power 9 watts = 1 thousand million watts = 1 billion watts)
The major suppliers currently, in round numbers, are :-
Gas 28%, 10GW
Wind 28%, 10GW (High because we are being battered by storm Ciara)
Nuclear 17%, 6GW
Coal 6%, 2GW
If 60 billion kilowatt hours per year will be needed for electric cars the extra continuous generating capacity needed will be 60,000 billion watt hours divided by 8,760 (24x365 = 8,760) which is 6.85GW.
Assumptions:- 1 billion = 1,000 million in Simons post. I have got my sums right!
