Can we power electric cars?
There were 240.0 billion car miles driven in the UK in 2013. That’s 386.2 billion car kilometres. [source]
If electric motoring costs 0.34 kWh per kilometre (from your 4 year old link), then that requires (386.2 × 0.34 =) 131.3 TWh of extra electrical energy.
Total electricity generation was 359 TWh in 2013. [source]
So switching to all electric cars would required the UK to increase electricity generation by 37%, according to the article you linked. If we all drove Teslas, which achieve 0.24 kWh/km, then generation would only need to increase by 26%.

Who is “you”? What is this 4-yr-old link?
Is this post part of a longer thread? If it is, I can’t see the rest of the thread. I’m looking at the following URL: http://blog.firetree.net/2015/02/04/can-we-power-electric-cars/

Which model of Tesla do you mean? Do you have a source for the figure 0.24 kWh/km? Your linking to sources is excellent when you do it, but it’s sporadic.
