In reality, I don't think Boris's plan will ever happen! Lets face it, what happened to his plans of a bridge between Ireland and Scotland!! he even got stuck on a zip wire over the Thames!!

Diesel has had it though, well and truly. It’s already being priced out to go into major cities. And it will become less and less attractive. I think those values will continue to plummet.


Observation: I would need to visit the city many many times to cover the cost of a£25,000 electric runaround. Although I fancy one anyway.

Let’s not forget peeps, this is for ten years time, so buying your last diesel in 9 Years and 364 days with a 10 year life
will see you thru to 2040

Long after I am pushing up daisies. Filters are in fact so good that in certain circumstances, when the ambient air is already polluted, a diesel car will tend to extract more particles from the air than it emits. Emissions Analytics worked with........etc etc

That is why things are being phased in and not done abruptly Wink

New diesel sales is declining rapidly. So in ten ears time there will be very few one year old models about.

We can all think of a scenario where it still makes sense, and where we don’t are. Heck i am driving a petrol guzzler with terrible fuel economy. And likewise i can drive a heck of a lot of miles with the cost difference versus a new more economical model.

But it will change over time. Just like today with the current changes it made more sense to buy a second hand petrol V8 versus the diesel version. Those didn’t come in overnight either 👍

I’m pretty sure that was a question of balance, something broke at a main grid junction point for a millisecond , and the balance was lost thus causing an automatic shut down to protect the systems.


That’s a part truth with the loss of frequency, the loss of frequency is a byproduct of loosing capacity drawing down the frequency... also the initial fault lasted 15 minutes before a restart could be called, then 45 minutes to get the power generation back up to service levels (demand).

What happened?

Just before 5pm, a technical issue at RWE’s Little Barford gas-fired power station caused it to go offline, resulting in the loss of 324MW of generation capacity. A few minutes later, Orsted’s Hornsea offshore wind farm also went offline, with a loss of up to 812MW.

The UK electricity demand at the time was 28,995MW, so the combined loss of up to 1,136MW of capacity represented just under 4% of demand at the time. As a result, the grid frequency (which is normally 50 Hz) dropped to below 48.9Hz (the lower acceptable limit is 49.5Hz). This resulted in automatic disconnection of some electricity demand to prevent the frequency falling further still.

This Still shows capacity is near demand with little ceiling, it’s common for power stations to trip or need to be pulled off line for servicing or fault repairs, so if we are so we have no reserve capacity.

Interconnector supply from EU equates to approx 5% or 2GW- as this was already in the chain it wouldn’t have helped keep the national grid up. More power generation is being shut down each year than growth of on demand power generation... again you can’t rely on renewables especially as the one ‘on demand’ renewable Bio mass is now slated to be phased out due to its CO2 emissions. Also Europe is in the same situation, moving from coal, gas and nuclear to renewables... if we have problems they likely will... no country is doing the right thing, they are all blindly going green and not keeping enough on demand [instant o] base load.

The maths just doesn’t stack up... just look at Australia, you would have thought with all the massive wind and solar projects over the last 20 years taking advantage of all that sun and wind would have be great but they have decommissioned most of the coal generation now leaving the system failing regularly with many brown outs and blackouts... that’s why Tesla’s stepped up to build the mega battery storage unit, they will need a lot more to sort their power issues even with most housing having solar on their roofs!

Will be interesting to see how this pans out and who will be right, but I for one will have my own solar generation and massive Li battery reserve so I can run off grid and charge my own car when the tech means it’s feasible (cost, range and life of battery) in 5- 10 yrs time. I won’t be waiting for governments to make the right decisions when they blindly follow the hardest green rhetoric.

Many moons ago I remember flowing an oil well (about 96% water) straight up the riser through the choke then straight through the gratings to sea until it had kicked off and could then be diverted to the separation train.

We got an attaboy award for our efforts from the company rep as we managed to get the thing flowing again, environmental concerns weren't so much respected in those days. Pon 1 for a litre of oil these days.

This article explains it: https://www.drax.com/energy-policy/britains-blackout/#chapter-4

As far as I can understand it, it was nothing to do with lack of capacity but more about a chain reaction of events that were badly handled by the way the systems are/were designed.

The article states it was nothing to do with the "unreliability" of wind farms. In fact, it implies the wind generation was reliable and the gas turbine was what cut out...

You said there are already more charging stations than petrol stations, but this isn’t enough by a long way... each petrol station has 4 or more pumps and each fill up takes a max of 15 mins even with shopping, a car needs at least 45 minutes on a fast charger to get any reasonable range, a 5 minute fill up in a IC car adds an average of 300 miles, not ~100 miles for 45 minutes... just do the maths,


You can't charge a petrol car at home though... most EV owners charge at home, the maths does add up Smile

ur20v wrote:

there needs to be millions more charging stations just to cope with longer journeys, this doesn’t help someone living in a block of flats or a terraced street with each household having roughly 2 cars the numbers and technology restrictions are massive. Also there are millions of households that work ‘from home’ so charging at work isn’t an answer either.


Most journeys are short and with ranges of 300 miles in EV's, most people won't need to stop to charge, a 40 min stop to get another 150 miles of range is going to be the exception to the rule.

Many new blocks of flats are having EV charging put in place already (my brother in law's a sparky and they've been fitting the charge points for the past 2 years or so).

There's a way to go with infrastructure still, for sure, but there's another 8 years before the laws come in and even then it's only on new cars, so it's going to be a gradual change over the next 2 decades realistically.

In just one decade of advancement we've gone from ranges of, I dunno, 100 miles or less, up to 300, in 10 more years we could well be seeing ranges in excess of what a big petrol or diesel tank can do today.

Charge times will also likely drop (they will do as the battery pack sizes go up anyway as you can dump more load into a greater number of cells).

Some EV manufacturers are already bringing out cars with *smaller* batteries as they reckon most consumers never use the bigger range (Honda's new "E" is an example of this).

Honestly, I don't think there's too much of a risk here tbh, the infrastructures made huge leaps in the last few years and you can literally charge an EV anywhere there's a plug socket Smile

We do have a bus service, but 4 per day!! We do have two 'local' railway stations, Pewsey and Westbury, but they are both at least 10 miles away. We only had one car until March this year so when I travelled home from the station (when I was working in London) a taxi from the station was £25 per trip! I was living away from home Monday to Friday but still it was costing me £50 a week to get to and from the station!


Public transport is crap and needs to be improved, that's for sure.

Even where I am with good/cheap public transport (costs me less than a pound to get 40 miles), it's still much slower than using my car.

There's some other fun stuff which helps this though, back in 2019 when I used to be able to go into the office, I'd sometimes use a combination of the train and an electric scooter which you can fold up and carry. Shaved a big chunk off my journey and meant I can go for a pint after work without worrying about having to drive, result! Smile

Again, I know this doesn't work for everyone, but some "electric vehicles" can be a fun way to travel too and there's lots of options to suit different people Smile

Of course the management at National Grid will state that there is no capacity issue - if they admitted otherwise they would be admitting incompetence.

Ask the guys that really know - the guys that actually work for the grid, on the grid.

Those that think there is no issue should see the yo, yo voltage that NG deliver to me - just as well anything I have here that is voltage sensitive is fed via a UPS.

Mrs C would have ordered an EV if it were not for the cost (we both drove a Peugeot 2008 EV & were impressed). The EV would be ideal for nearly 100& of her motoring & a chunk of mine.

Lets face it, there will never be enough charging points for everyone, not even slow ones using standard 13a sockets.

Compromise with a mix of power sources, better public transport. more working from home, working closer to home etc and there will no longer be the need to be 100% green (or whatever you want to call it).

And that is the good thing about Policy. With it becoming the norm the cost will come down. Well at least relatively. As actual costs of all cars have gone up and up and up.

The UK isn’t alone in pursuing this, Manufacturers and other industry will follow suit.

What I can't understand is why there's very little talk about hydrogen fuel cells. They are way better than electric batteries in so many ways, yet they have been largely overlooked.

There's a lot of discussion going on about the reasons why batteries are being used rather than hydrogen fuel cells, I could write an essay here on the topic!
Unfortunately it all comes down to a seriously flawed human perspective. Remember back in the 80's there were two types of video format, Betamax and VHS? Which ended up being the forerunner and why?

My guess - batteries can be recharged at home whereas you cannot really create hydrogen at home. So when there is no infrastruture in place batteries look "easier" to roll out.

If hydrogen could be made cheaply then I am sure it would be the only game in town. But when it costs so much compared to petrol (let alone diesel or electricity) not a chance. However, I seem to recall that one of the Scottish islands has such a surplus of wind energy they installed a hydrogen making plant, that in effect is free to run. 2010 Range Rover TDV8 Baltic Blue Autobiography (2011 MY) - SOLD Sad
