Here’s one estimate of the cost of converting internal combustion vehicles to an all electric fleet.  Certainly, it’s a single datum, but it’s a useful one as an outer bound, plausibility estimate.  Nicola Sturgeon is Scotland’s First Minister, and she wants to replace all of Scotland’s internal combustion vehicles with electrically powered vehicles by 2032, which lends irony to the outer bound datum.  Great Britain’s green energy aficionados want to replace all of Great Britain’s internal combustion vehicles with electric ones by 2040.

Professor Jack Ponton of Edinburgh University has rudely run the numbers [emphasis in the original].

If you want to do this with wind turbines, you are talking about 16,000 more wind turbines, four times as many as we have at the moment, and I’ve estimated that would occupy some 90,000 square kilometres, which is approximately the size of Scotland.

Hmm….
