Another thing is that there's no point in everyone rushing out and buying electric cars when the UK energy mix is like it is, we're still burning **** loads of fossil fuels to generate the power. It makes sense in somewhere like Norway where they're 88% hydro/10% wind. We'll never get anywhere near that level of renewable energy our only hope of getting close to the fantasy of net zero is by building more nuclear power stations and living with the associated risks, the way this country (mis)functions this will be a generation away same as building the power distribution networks we'd need for 100% electric cars.
No rush, but good steady transition as end of life ICE cars are replaced with EV's, as the renewable grid scales up.
Of course we will get to Norway's level, there's already 1.5 x more wind being planned/ constructed by 2030 than we currently have active, and there's even more than that in feasibility stage, and that's only offshore. We have like 20KW currently and have 50GW planned/ in construction for 2030.
They've just lifted the onshore ban, this is much easier and cheaper still, it will open the door further.
There's 70GW of solar planned by 2035, we currently have 10GW.
We currently have like 20GW wind and 10GW solar, and last year that supplied 37% of our demand, if we have that upped to 4x then it's ~150% on todays demand, by 2035. Add in 20% for nuclear and biomass then it's better still. We only used 30% fossil fuels last year, in 2012 it was 75%.
As wind is so cheap, and simple to construct in the UK then even relatively inefficient storage methods will make sense, and become more and more viable. You don't need perfect storage if you have a lot of excess a lot of the time.
We don't need much more nuclear, the less we can get by with the better, as it's extremely expensive, about 4 x the cost of wind and solar per unit. It's not like it's not windy or sunny for 3/4 of the year. When it's not windy, it's typically sunny/ high pressure and vice versa, they offset each other well.
If you store wind power at 25% efficiency, it's the same price as Nuclear. Nuclears getting more expensive, wind and solar are getting cheaper.
Then there's interconnectors, when we have tons of wind, we can ship it off to Ireland, France, Belgium, Denmark, Norway etc, this is all possible already, we already do it and vice versa. Norway can basically use our wind, instead of opening the valves on their hydro, they can work together very well, same with France's nuclear etc.
There's loads more interconnectors planned and in construction, think of it more like a balanced grid between us and the EU, as that's what's happening, as that's what will work best.
The good thing about EV's is they can be charged at night mostly, when other demand is low, but the wind is still blowing at night etc.
