I find your statement confusing, if we can't cope with the electricity demand now, leading us to import more and to built more power stations, how are we going to cope in any future when the demand is higher. The increase of sales in EV's was such that 1 in 10 vehicles sold in the UK are electric and that will only go up. There is a estimtaed 975,000 electric cars on the road in the UK and 590,000 plug-in hybrids and that figure will only go up.
As for additional power stations being eco friendly, or nuclear, I don't think those two words sit together very well as many would rightfully argue nuclear is hardly eco unless you wish to split hairs by stating just 'in the generation of electricity'. Plus this current government, that can only hope to be rid of soon, isn't committed to eco as they wouldn't be be building gas fired ones that had no carbon capture.
EVs need to be charged off peak and most of them are..... if anything EVs HELP the grid by breaking the back of the duck curve. in the future hopefully they can help even more by owners donating a percentage of their battery when plugged in in peak times to smooth out even more with the carrot of even cheaper off peak charging.
you dont need to take my word for it...... just dont believe the gutter press either. multiple people from the national grid have said intelligent charging of EVs simply is not a concern for the grid, why people believe sh..e in our media over the actual people who run the grid just boggles me.
That said...........we need more renewable. my preference would be more wind and every house roof having solar, and carpark awnings and industrial buildings...... then my preference would be solar on lakes as well as tidal.
even then maybe we need some nuclear as well......... not perfect but sometimes perfection is the enemy of the good.
i am generally not a huge fan of on shore solar farms *however* if done correctly there are some crops which are complementary to solar farms and they have been shown to help natural habitat as well, so perhaps even they are ok as well.
as for importing diry energy. last year France had problems with their nuclear stock and some of our interconnects were damaged as well. AFAIK both these issues are now fixed, but for sure, as well as more renewable generation we do need more interconnects.
hell there are wind turbines sat unable to produce properly because the national grid cant connect them properly. There is a lot of work to be done.... but using hydrogen which is WAY more inefficient than just using the electricity in a battery EV is just making things even worse. (as in needing - from memory please dont hold me to this 6kwh of electricity to give 1kwh of thrust in a Hydrogen powered car, vs 1/4 of that for a battery powered EV). (and the electricity still needs to be generated for both vehicles before that point)
ultimately EVs are not green. IF you want to be green walk, or cycle..... but they are greenER than any other car.
btw i am far from perfect. i should cut down my meat and i am going on holiday to spain in August, my carbon footprint is much larger than it needs to be. but the thing with EVs (if you can charge from home) is for the vast majority of people who can charge at home its reducing your footprint with hardly any hardship or downsides.
IF i couldnt charge at home i would not buy an EV......... but equally i would not buy a brand new ICE car either...... There are so many really nice ICE cars that I could buy 2nd hand now that it makes far more sense to buy one of those, and hope that in 5 years when i come to upgrade again charging an EV has improved.
There is nothing wrong with driving an ICE car imo...... it is buying brand new ones that i personally think is a bit daft. (i do wonder how many of these people living on the 15th story flat or what ever that the media likes to portray as why they cant buy a brand new EV, so have to buy a brand new diesel instead actually exist anyway........ To each their own and all that but if i lived in such a block of flats if it were me i would buy a cheap 2nd hand car anyway and save the money)
