I’ve not driven one but forced into buying one through work.

Thanks to tax breaks it’s a no brainier, I do approximately 30k a year so ordered a Tesla m3 Performance blind. Never driven one, life’s more fun when you take risks (like going bareback in Thailand)

Will be doing a 2000 mile trip to Italy in the summer, I don’t see a 30 minute break every 270 miles as an issue.

If electric cars are "clean" and will save the world when all car companies have been forced to only make them.
By this time we will all be on 500kw chargers or possibly a 1000kw for a really fast charge, so where will all the electrickery come from. Late last year the Nat Grid people were talking about power cuts if we had a bad winter.
We have not got enough older type power stations, the clean stuff only works on windy or sunny days, so we will struggle to keep the lights and internet going on a cold winter.
We have still not agreed who will build any nuclear power stations yet or who the hell might build them .... China ???
with no answers for these option, I don't think the 100% electric cars will be going very far each morning.
Whole country gets up (not the ones withelectric alarm clocks, put the kettle on ups (or should it be UPS), no tea or coffee. Go to the garage for the car, ( or plural if spouse and sprogs all go out to get the car). All flat!
Go back to send a message to work, ups no email no internet at all.
All go back to bed and self isolate, just like in the COVID 19 days!
Seriously I can't see any chance of us all going electric any time soon!

COME BACK DRAX ........ OH dear we blue it up!!!

Admittedly copied from EV discussion forum

You see it looks a bit like this:

31.7m cars
Average Miles 7,134/annum
Total Miles 226,148 million
Average EV efficiency 0.3kWh/mile
Total Power Required 67,844 GWh

Total UK Elec 2018 333,900 GWh
Total UK Elec 2005 406,682 GWh
Reduction: 72,782 GWh

Typical night time drop 15GWh equivalent to 43,800GWh per Annum for 8-hour night.

So the drop since 2005 is more than the total required for EVs and the night time sag is 2/3rds of EV requirements.

Comparisons to Total Capacity leave plenty to spare. Peak to Average is 17GW available 20 hours per day.

So it’s only about a 20% increase and less than we did before. No coal as banned from end of 2024 and only 3% now. We will keep building renewable output and EVs will continue to get cleaner.
