Electric vehicles, broadly speaking, consume the same amount of energy as would be used to refine the fuel to drive an equivalent petrol or diesel vehicle a similar distance. So little or no net increase in electricity demand. As more and more of our electricity comes from renewable sources, electric vehicles will be genuinely ‘green’ and sustainable.
Firstly the total ‘energy’ use of a refinery to refine one gallon of fuel isn’t the same thing as total ‘electricity’ use.
While the fact is that gallon of fuel contains a lot more energy than the energy used to produce it.The end result being a lower retail unit price than electricity.IE around 10p per kwh at 9 mpg including road fuel taxation.That fuel consumption/cost figure also proving the lie that a truck supposedly only needs 2 kwh per mile. 
While we all know that this is all about creating a captive market for the expensive dangerous nuclear generation industry.While it’s equally obvious that they aren’t going to cap the oil/gas fields or shut down oil refining because that would mean the end of the civil aviation industry for just one example.Not to mention economic suicide for oil producers and the end of all oil and gas revenues including the UK’s.
On that note at best the whole thing is a scam to make the UK motorist dependent on expensive nuclear electricity and middle men EV suppliers.While our own oil is exported to be used elsewhere and by the aviation and chemicals industries.All dressed up under the bs ‘Green’ agenda.A bit like Nicola bleedin Sturgeon shouting about CO2 and climate change on one hand while shouting about wanting Scotland’s share of North Sea oil revenues and Scottish oil industry development on the other.
