owww... that's painful... at current electric and fuel prices, you're going to go from £1000/year to £2200/year if you switch to electricity... Approximations...Just looked at our power bills the other day as the contract is up for renewal. Spoiler alert, rates are going up.
Bit of a rough thought experiment/estimation. I am sure there are loads of mitigating factors in all of this and the numbers are only indicators at best.
We have a gas central heating/hot water boiler. Modern combi thing. Two of us in a three bed semi. Very frugal and sparing with the heating. The thermostat is never set higher than 18. I like a decent shower, that is the only indulgence really. We have a log burner which probably gets used two dozen days per year.
Annual use to Jan 2021:
Electric 2793 KWH
Gas 9765 KWH
I work from home due to the current carry on and don't drive as much as I used to. Probably fill the car every three to four weeks.
16 times per year at 50 litres at 9.6kwh per litre is 7680 Kwh
For an electric equivalent roughly:
Divide by two due to electric motor efficiency. 85% vs 40%
3840 KWH
So if we have to decarbonise my electric demand goes up from 2793 to 16398kwh. Nearly six times as much.
I suppose storage heaters could be employed at night when there is no demand so and so could the charging of the replacement electric vehicle, but if everyone is doing the same the power and cheap off peak electricity may not be there like it is at the moment.
I guess they need to start building something.
Now atm there's maybe cheap tarrifs, but you can bet your last bootstrap that with the strike price agreed for Hinkley Point C, and the rising demand due to cars, the price of electric is going up, not down.
It's a crazy thought... we don't generate enough electricity as it is, and yet if we follow the EV trends, we're going to need to generate 5 times as much as present!
