"U.K. power generation can genuinely displace fossil fuels as the backbone supply. "

We have a bit to go.

Fossil fuels will be needed as long as we use wind to generate electricity because unreliable wind needs reliable gas backup.

The oil bit is transport, not power generation.
With enough wind turbines that can be displaced, but requires a different form of propulsion.
The other absolutely crucial part of the puzzle that the graph doesn't show is the impact of revolutionizing energy efficiency.
Switching from oil to electricity to power transport shrinks the vertical magnitude of the yellow band fourfold due to maths and science.
That's for the same distance driven.
75% or more of the yellow band is waste heat, that's the bit that's killing the environmental case for using oil for transport.
Electrification by and large eliminates the waste heat portion.
Exactly the same energy efficiency argument applies to gas consumption for home or commercial heating.
A heat pump requires a fraction of the energy input to achieve the same heat output as a gas boiler.
This is the COP value for the heat pump, usually between 3 and 5.
If the COP is 4, the energy input is one quarter that of burning stuff to produce heat.
The heat pump works by extracting heat from the ground or the atmosphere, so essentially does exactly the opposite of dumping waste heat into it.
The solution to energy challenges is to use technology.
Whatever approach you take, that technology is electrically powered.

I see some people mention that EV isn't as fun as ICE. Surely that depends on what you're comparing it against?

I can only go by my own examples/experience, but I swapped a 330i for a Model 3 Performance, and the Model 3 is no less fun relative to the 330i. I've lost some engagement (noise, paddle shift etc), but I've gained power/acceleration. I drive my wife's Mini Cooper S, I used to love nailing it down a country road, now I don't like it. The steering wheel is too big, the steering isn't sharp enough, and it has little frontend grip. It gets my wife to work and back and she likes it.

For many of us, we're buying cars that have to strike a reasonable balance between performance, handling, fun, functionality, efficiency and cost.

I'm sure that when you compare EV's to their ICE equivalents, surely there's very little difference in how 'fun' they are? Most people don't even care.

I've said this before, but if you're driving something like a BMW M3 or a GR Yaris, there's a reason you've specifically bought those models, and you're probably right. I don't think think there's an EV out there that really encapsulates the experience you get from those. Sadly, many of us can't afford to run an M3, or shoe-horn a GR Yaris into our family lifestyles, even though we want to.

Yup. Lots to do. The key is that due to the geography and geology of the U.K. we are one of the few developed nations that has a relatively clear path to achieving the replacement of fossil fuels as the core energy backbone.
Yes we're just missing a soltion for energy storage, either green hydrogen, or batteries.

Or better still, 2 way chargers so we can all choose to allocate 10-20% of our EVs for home energy storage (average house uses 10kwh/day, which is about 16% of an EVs capacity), so we have our own grid smoothing device parked on our drive.
Storage is hugely inefficient which is why the best way to store nat gas is to leave it in the ground. biggrin

We are very unlikely to fill the U.K. with tonnes of battery packs in fields but rather utilise a blended solution based on trade. Excess generation just gets sold, firstly to domestic consumers who have batteries they're paying a monthly fee to just have on the driveway doing nothing. Then it's down a pipe to the mainland where it will ultimately be bought by someone down the far end who has a shortfall. The key is how to then deal with when we have a domestic shortfall due to periods of low to no wind. First is that you build over capacity of generation. It's better to have too much and have to export it for foreign currency than it is to have just the right amount but regularly needing to import. Secondly, you haul back from the continent what you sent over the previous month as part of your international grid solution.

The concept of taking temporarily excess electricity and losing half of it splitting desalinated water into hydrogen, then losing more during storage and then a big slug lost when converting it back to electricity just doesn't make sense economically which is why Britain hasn't rushed down that rabbit hole. We also have nat gas offshore where it can be militarily defended and also blocked which makes it the smarter fallback solution. Only the truly desperate nations will have to head down crazy paths like having to try and store GH or worse, needing to synthesise long chain hydrocarbon blends using laundered carbon credits (and of course, we'll be happy to sell them the carbon that they need as we will have an excess from the scrubbing of the gas power stationsbiggrin).

Agreed. Even California, storming ahead has only 10GW/40GWh of battery storage. Or 1 hour UK demand.

But a distrusted collection of batteries in homes and cars can go a long way. V2G is long overdue.

It'll go some of the way. Private owners of batteries will be very easy to dupe into being under paid for letting a utility company use their infrastructure to maximise profit while avoiding capex. biggrin

The real key is whether it goes into someone's car battery or house battery or sent overseas the efficiency comes from just selling it asap for whatever price a buyer at the time will offer rather than spending £billions building mega batteries or fairy gas tanks to try and store it.

A domestic House will probably be able to disconnect from the Grid and live of their cars quite easily once the slight issue of the householder not being the owner of the battery in the car gets resolved. I suspect the greater burden lies in delivering a constant supply to heavy industry, something that fossil fuels do seamlessly but is harder with renewables.

The GR Yaris if a damn good car, and I've love to have one, but surely something like a Model 3 Performance would be able to live with it?
Not in the circumstances described. Not a chance. Traffic lights and straight lines my money would be on the EV but that isn't why you buy a GRY.

I'm not so sure, 4WD, super fast traction control, active brake bias adjustment (yes they really do that) and good weight balance make performance EV's surprisingly good even in the situation you describe. I've driven my EV in the wet on track and while I didn't see any Yaris's I was overtaking M4's pretty easily.

It's possible to really hussle a Model 3 along. It's quite grippy. I've had the back end squirm slightly on corner exit when really pushing on and it was quite progressive.

Something properly agile like a Clio 200 or Yaris GR would definitely be quicker round some tight and twisty corners.

In the same way as a Clio 200 or Yaris GR would do the same to most road cars like 335i BMWs or Merc E350s.

I tried other EVs, namely the Kona and Niro (older models) and they felt like pretty ordinary SUVs to drive, albeit with 7 secs to 60mph.

But the Model 3 felt closest to a fast BMW to me with the low driving position with legs nearly out straight. Not dissimilar to the M2 that i had a couple of years ago.

But it's no hot hatch that's for sure.

It would be interesting to find out. Why do you think the Yaris has inherently better traction?

Of course it is, But the paragraph I was replying to said

" No one can now not understand why replacing both oil and gas as the primary energy fuels is simply not even up for debate as there is no defence to leaving the U.K. economy and the financial security of its people unnecessarily exposed to the global pricing of oil and gas. "

IE Energy not electricity. Even with 100% non fossil electricity we would still be exposed tp global oil and gas prices.

Less so if we can also run our cars and our domestic heating on non-fossil electricity.

Talking of EV's, can anyone explain to me why it appears that half of the model 3s listed on eBay have been write offs in the past?

Have to say, if I was looking for a car and had somewhere to charge it a £20K non crashed Tesla Model 3 would be high on the list.

Yeah, this is why the Tesla Model 3 has really been the only EV that I have seriously considered as a potential replacement for my current 3 series, because its a normal saloon and I know would do the same job quite well. The RWD variant particularly seems a good choice. I understand that with a few tweaks Tesla Model 3s are also doing very well in club motorsport events. I know in his recent review, Harry Metcalfe was quite impressed how the facelifted Model 3 went down his favourite Cotswold B road.

Some of the smaller EVs also I find appealing, like the Mini, Fiat 500, Corsa, 208 etc. I suspect they're quite a bit of fun. The Top Gear lads seem to have a blast when they reviewed a Corsa, Mini and Honda E a couple of years back.

I think there’s definitely been an issue with insurance companies writing them off for far less damage than you’d expect, along with a shortage of parts which meant huge delays in repairs and hire car costs. This has fed into high insurance costs.

Whether this remains an ongoing issue I don’t know.

I am. There are very few road cars on the planet that can match the Yaris in the circumstances under discussion.

As I said, straight lines, power wins. On the ubiquitous damp B road, more powerful cars than yours won't keep up.

I don't consider myself a track expert but I know enough about cars to know that power matters a lot more on circuits with plenty of straights. The GRY tops out at about 140 so there are stacks of cars that would be faster on those circuits. Lots of corners and hardly any straights different story.

It's no more than the old story of horses for courses not one car being better than another overall.

Deluded EV owners chasing Toyotas and Caterhams through bends and understeering off the road. Happens all the time. Give 'em five seconds 0-60 and they think they're driving a Red Bull. wink
