Like most people my home energy bils and my fuel costs have risen rapidly and An EV becomes more tempting with petrol at £1.80 per litre
However, looking at my energy bill I pay 7.37 pence per KWH for gas and 29.4 pence per KWH for electricity. so four times as much. Now sort of that I understand as some UK power stations burn natural gas and you pay for the power station plus transmission losses higher than gas line to your house , or you are paying for recent wind farm investment costs not yet written off.
Now in the UK petrol at £1.80 per litre about 50% is tax so a litre is around 90 pence pre-tax, - the correct economic way of measuring it. I think petrol has 8.8 KWH per litre so buying petrol I pay 10 pence per KWH versus 29 pence for my home electric.
Obviously, the losses in an EV are very, very low vs an IC engine but if I assume 35% wheel efficiency for my IC car the cost of petrol is 28p per KWH at the wheels - i.e virtually the same as electric charging cost at home for an EV.
I know that isa very crude calculation and, and not surprisingly, the UK government is planning to switch car fuel taxes to some sort of milage based tax on al cars including EV's. At £26B fuel tax per year they can’t afford not to.
Am I doing something wrong with my calculations or is the real cost of EV home charging in UK basically the same as tee real cost of fuel for an IC car?
