Being at a meeting yesterday attended inter alia by Greg Clark MP, in which he spoke about future infrastructure, I took the opportunity to ask him about the future of the grid if we all go electric - I suggested it'd need to be three or four times bigger than now along with new power stations.
He spoke about that we'd need a "smart grid", which could suck the juice out of the batteries of our electric cars when we get home, and that they'd then be recharged later in the evening. After the meeting I asked him whether anyone had done the sums on that and he said they had, although I got no detail. He also said, after I asked him, that he was very familiar with "Renewable Energy without the Hot Air".
Pity that TNP and whichever Mike worked for the Grid (?) were not there, as I don't know enough about the topic to argue much more.

That's never stopped you in the past? ;-)
The surprising bit is that you realise you know nothing about that but know everything about our future outside the EU? Or simply don't care as much about that as fulfilling your own personal anti-EU crusade (at any cost to all of us)?

Well its one of the narratives being spun by the renewable lobby.
(its the Other Mike you want)
And its bollocks of course.
Peak demand is cold winter days, and if you car has been on charge overnight, its out and about during the day and evening.
Its not available for grid backup.
When I first got involved the problems of 'what happens when the sun don't shine and the wind ain't blowing' were hand waved away with the meme 'the wind is always blowing somewhere'
The evaluation of the truth of that meme was the whole reason to create Gridwatch.
Even David (Mackay) had only got as far as addressing enbergy density, not intermittency.
The ex oil droum chaps at Euan Mearns blog are doing the best maths on that - probably in the world.
Way better than the national grid publishes. I am sure in private they know the score but it's more than the jobs worth...
The problem is simple. We can potentilally smooth out diurnal demand varaitins with cheap heat stoiratge - ghouse built for exzample with massive warm water tanks under the house that can store off peak heat pumped heat ccan in theory keep the house warm till the mext night - its not a huge cost on a new house. Dine ob an industrial scale for offices and warehouses and so on its a reasonbable reduyce of poeak demend and might ecven get you through a cold snap.
What it wont do is get you through winter. ' It can't. Instead of being baffled with the 'think of a number' bullshit you need to asses the longer term grid demands.
This is especially relevant with solar because winter sunlight is only around 10% of summer sun.

The problem is that the significant gap in renewable energy is a 6 month one in winter, with solar, and a weak to two weeks with wind.
Currently we are running with around 15GW of wiond capacity vthat has never actually generated more than 10GW as far as I know.
So lets take 10GW for a week, as the battery requirement.
I make that the combined output of 16 million cars all flattening their
100kwh batteries to replace the wind that isnt there.
Now think about the 10GW of solar, for 6 months requirements..
THis is all known to be virtue signalling nonsense. The question is why are we being lied to?
Cui Bono?
I think anyine who isn't so completely brainwashed that they can't tell propaganda from information, has, watching Brexit over the last two weeks,. begun to get an inkling of exactly who is telling the lies, just how much they are lying and how extremely dangerous and powerful they are.
And it isn't Nigel Farage.
Lying at a political level is simply how business is done.

Do you not think though that nobody will allow the grid to uncharge their vehicles? Just unplug when charged.
After all what is the point of a car where you cannot drive it at some times even if you want to?
The point is that the change to Electric stuff, if indeed this is the way things will be done needs to be managed so demand does not exceed supply surely? Brian

Or not plug it in when you get home - wait until later.

"Uncharging " would be at the discretion of the car owner and he/she would be paid a premium price. But it seems a hairbrained idea to me.
