Your in the usual ill advised cuckoo dreamland. There are dozens of reasons ev can NOT work for a high % of the nation. And the vast majority of cars would be plugged in around 6pm, the amount of charge required is not the overwhelming problem it is the fact a colossal load will be placed on the grid at the peak demand time, YES the peak demand time! The national grid and your local network is light years away from being able to provide this capacity be it for 1 minute or 8 hours, the grid has not got anywhere near the capacity, end off! It’s irrelevant that sometimes all things being good and perfect there will be some spare capacity. If it’s not available 100% of the time it’s still useless. Very often the grid is at or near capacity in winter at around 5-7pm and that’s now! A high pressure weather system makes wind power redundant and solar is none existent leaving just mainly (dirty) gas and some nuclear and some coal essentially. This happens every winter fairly regularly. Add to it any substantial amount of ev’s it’s way OTT and candles out. Still got huge local network issues to overcome and the fact the vast majority of cars are nowhere near a power source of anywhere near the required capacity. NO streetlight could provide anywhere near the demand.
The argument is currently so crap it’s embarrassing. A perfect example of thick politicians and sheep following them.

I think it's best to agree to disagree as no one knows really what the future holds.
It doesn't really matter what the opinion is as to whether it will work or not, the only consolation will be that the naysayers can say 'I told you'.
Lets hope there are some with far more knowledge than us mere mortals on here working on it....

Gas turbines are 35 - 60 % efficient depending on type. Diesel engine is 35-45% efficient and coal power stations are around 41% efficient so pretty irrelevant and your forgetting that is at source. The electricity has to be transformed up and distributed through large networks, transformed down numerous times, put through a charger into s battery then put through an inverter to a motor to proved mechanical power, every step of that journey has losses which will result in the original efficiency being utterly irrelevant. Be lucky if the final efficiency us much more than 20% and I put my money in diesel being far more efficient overall and petrol too.matthen wrote: ↑Sat Mar 30, 2024 8:02 am Doesn't matter how the gas is made - the plants are 50% efficient: considerably better than an ICE is.
And there will be an ever increasing number of days/hours where we’ll have excess power available, thanks to the silly amount of wind turbines we seem to have installed - perfect for dumping into a car battery.

So if we can't all charge our cars up at the same time, the system is useless? You remember what happened when everyone tried to fill up their petrol cars at the same time? No fuel anywhere, and weeks to recover the supplies.4251 wrote: ↑Sat Mar 30, 2024 9:10 am4251 wrote: ↑Sat Mar 30, 2024 9:05 ammatthen wrote: ↑Fri Mar 29, 2024 5:19 pm
You'd be wrong then. There is plenty of power available overnight, and to access the best tariffs you let the provider decide when to start charging your car.
Sure, if everyone plugged in a car (from empty) at half past 5, the grid would fall over. But: the average person does 18 miles a day. That's approximately 6kWh of charge a night. Call it 7kWh to account for loses.
So, they'll be running the chargers for less than 1hr. Spread between 10 and 6 AM, where we typically have 30 MW or more of generation capacity sat idle, it'll generate no more noise than the countries electric showers do.
The maths has been done. The problems will be at motorway services on bank holidays. That is easy to address with an on demand gas plant (size of a shipping container).

People won't all plug their cars in at 6PM, because they will be charged £££ to do so (and because there is no need to).
On street parkers will need to charge less than once a fortnight on average. New power sources are connected to the grid all the time. Transformers are being upgraded all the time. The problems you see as insurmountable will be dealt with either with a carrot or a stick - and most people will find electric cars more comfortable and convenient than ICE ones.
We all love petrol engines, but the world is moving on: and the sooner we remove our dependencies from tin pot dictatorships the better.
Also, if there isn't the power to charge the nation's cars, there certainly isn't the power to generate green hydrogen or synthetic unleaded - because the processes are far less energy efficient and require more power than charging the cars directly.
