Good if the bodies last and the engines and it is batteries just needing replaced.

Unless you have a separate connection from the green generator then this statement is always untrue. The National Grid cannot guarantee that green generated electricity goes to customers paying a green tariff, all they can guarantee is that you are paying to put green energy ONTO the National Grid but cannot guarantee that you will be SUPPLIED with green energy.

@J.R.Was that a Toyota Prius hybrid?   Did exactly what it was required to.  Then Vauxhall had  the Ampera. A range extender that many owners love, and they are pretty economical.

 

Note her using right hand on centre screen while stationary.

This is the issue. Right handed people not good at using touch screens or controls with a left hand while driving.

The screen a full stretch to the left, or for those that need te seat back and might have long legs and a normal body but not arms & fingers like a monkey.

Still a lot of the Toyota Prius on the road, especially around this area of England, close to London it makes an ideal commuting car I understand. At one time it seemed to be the company car of choice for to reduce their tax burden as it lower tax penalty for them.

 

The dash on that Vauxhall Ampera is just horrible and is like so many modern cars, incorporating so many controls into its touch screen is just a recipe for disaster as you cannot operate it without looking at it. Its just as dangerous as using a mobile phone hand held while driving, give me conventional switches and knobs any day please.  TBH, some of the controls on the MK3 Superb are now integrated into the screen and I find them so hard to use, as you said, left-handed, go over a stone in the road and your finger misses the touch sensitive button and operates something else instead.👎

Yes, but some were claiming that is good enough still as it meant that someone would be using green energy, so it had the same end result, except that first person paid extra for it? But according to the Sky program, that is not happening all the time as green suppliers are not being used in some cases and instead the grid is firing up gas powered plants etc.

Just watched the whole Sky article and the electricity to the UK / ENGLAND from Morocco.

the Pylon Objectors in the UK, that is very much in SCOTLAND and England.

 

Get the pylons up where needed and where they do not want them just disconnect their electricity.

Can we have the French pylon design as they always looked prettier than uk ones ?

@lol-lol On the same trip, I would expect to get something in the order of around 60mpg so would be pretty similar to his costs for the Tesla, wafting is what the Superb does best, but it would more polluting though.

The planned route is within 1 mile of my house, and I can report that there is quite a bit of local resistance to the pylons. Question, why can't they dig a trench and bury the cable, surely the cables could be protected against corrosion etc?

Heat.

 

It cost a fortune to do this from Dinorwig to the National Grid as Snowdonian national park demanded the cables were buried to not spoil the park.

Insulating ultra high voltage cables to put underground for great lengths would be cost prohibitive. The cables between pylons are bare for heat dissipation?

Probably do similar mpg in the Arkana which shows how Diesels are no longer needed for new cars.

 

Pollution from the diesel going thru tge cities, as he does with Newcasle and Edinburgh I expect the residents will be happy to see, or rather breath the less polluted air.

Think so. Dinorwic has these sheds every kilometers or so to pump air to cool those 2 GW lines. Think they have moved them recently after the near 30 years they have been operating.

 

The Norway and Dennark interconnectors are 1.4 GW, what is the Morocco interconnector size ?

Hmm, well I wouldn't go that far, I can go for anything from 580 to 950 miles on a single tank so would be need to be refuelled on route, so in the event of a power outage, I can keep going or if trapped in bad weather, I could keep my heater on for longer, so swings and roundabouts.

 

Plus of course, the Superb is a bigger car and has way more interior space so makes it a better car for long trips, and as mentioned before, I need that space, being 6ft 4" and so are my 3 sons, and I have exceedingly large feet, size 15, so need lots of feet room in the pedal well area.

The only reason I can think of for a diesel is to tow where the low down torque and the extra weight of a diesel is actual a plus.

 

Fuel tanks are becoming smaller and smaller. My old A4 had something like a 67 litre tank. Saw 980 miles on the range, 1.9 PD engine, noisy but good.

 

With decent hybrid lecky assistance the torque is impressive but system will not allow that assistance to apply for more than a few seconds. No good for towing a rig up Holden/ Telegraph hill which will take a minute or two of sustained torque/power to rise up from the Exe flood plain to the piedmont of Dartmoor.

Unlike some, I don't profess to know everything and I have never been involved with power generation/transmission. If a cable runs hot then its a power loss and is something I would not have expected in the national grid as they need to generate more power to negate the losses.

That makes them not being truthful as putting green energy onto the Grid is absolutely NOT the same as being supplied exclusively with green energy.

 

So many people have little or no understanding of how the Grid works that companies can get away with telling untruths, even some Chartered Electrical Engineers I have worked with don't understand the difference.

 

Apologies if this has already been posted

@Stonekeeper, I'm not sure if it has or not, but I've seen it before and personally I'd rather have something posted many times than not at all in case it has been posted before. 👍

VW accelerates its cost cutting exercise and the move from Germany to China........

 

 

I think VW is going to be the first to pull out of home production, it has been going on in many other industries here in the UK for years a company I used to work for opened up factories in the fer east many years.

Their economic model is just uneconomic. Their production technology overtaken by China and TESLA.  The 21st century is the Asian century.

Europe still has a lead in Aerospace but that is about the last industrial area left to go East.

 

 

This Norwegian garage took apart a submerged M3 battery and it's very interesting to see what goes on inside the failed battery. They concluded they need 2 more modules out of 4 in total, so it was not worth repairing. I'm sure the usable modules will be kept for other vehicle though.

 

Suspected cause for submerged battery failure is due to breather thingy letting water in.  (video starts at that point)


Shame Tesla uses so much glue in their battery and must replace modules, 4 huge modules in this pack. Nissan Leaf, of course one of simplest EV, can easily replace stuff right down to individual cells. (earlier video in this channel had repaired a 2011 Leaf)

The thing is, none that I checked have used the word "supplied" or "supply" when talking about green energy. All are quite straight forward in their wording in what they mean. No one is trying to be untruthful.

It comes from renewable sources like the wind, sun, and sea. The fact they’re renewable means we’ll never run out of them.

We’ll match 100% of the electricity you use with renewable sources, such as UK wind and solar – helping to reduce your home’s carbon footprint

 

Yes, the kWh I take may not have came from renewable sources.

But if for the kWh I used, I paid renewable "green" generation to put it on the grid, then I am, in effect, receiving green electricity.

Think of the grid as as a big bucket. Anything I take from it is put back by green sources.

The more people participate paying green sources, the more incentive for green generation, the more green generators. Demand'n'supply 101.

So why does it matter where that particular kWh came from?

But if they sign more people up for "green tariffs" than the amount of green energy generated that would be fraud?
