General Discussion Area / Re: MPs want to bring forward sale of fossil fuel vehicle ban to 2032

UK currently uses about 53Gwh of electricity per day.
We use about 1,559,000 barrels of oil per day where around 70% (USA percentage) is used by motor vehicles and there are on average 1,700kwh of energy in a barrel of oil. So in this new era of electric cars we will be using 1,559,000 x 0.7 x 1,700,000Wh = 1,855,000,000,000wh or 1855Gwh with our current peak generating capacity of about 60Gwh, so current generating capacity is 1/31 of what is going to be required in 25 years time, so nothing to see here, no problems with coping with the extra demand, oh no.
In 25 years time almost all fossil fueled cars will have be remanufactured into beans cans. With UK's impressively fast planning and infrastructure building record and power companies being reluctant to invest in new generating capacity, everything should be just fine here, so nothing to worry about.
Whilst I agree with your general point, you're several orders of magnitude out somewhere. The two obvious errors are that "motor vehicles" includes busses and lorries, and AIUI the govt is only talking about passenger cars. And the second is that battery vehicles should be significantly better at using the energy than an internal combustion engine is. But that still doesn't account for the differences to the figures I worked out :
Lets look at something else. https://www.licencebureau.co.uk/wp-content/uploads/road-use-statistics.pdf
Page 8 says cars accounted for 244.4 billion vehicle miles in 2014. That's 670 million per day, or almost 28 million per hour (on average).
The Leaf and Tessla battery/range figures indicate you can expect to get about 3 miles per kWh of battery charge
This means that if/once all cars were electric/battery, the grid would have to supply an average of an extra 9.3 Million kW every hour. The difference between night time and daytime energy generation in the UK is currently about 10GW, but if you restrict charging to between 8pm and 8am then you're going to need to generate an extra 18.6 GW during that time. So you still have to find 8.6GW of extra capacity from somewhere.

Basically 3 extra Hinkley point C's coming online from 2040 onwards will do it. Is the planning permission in place yet?
