It isn't meaningless. The average terrace residence is 8 kWh. Note kWh, not kW. Your EV would double that. It is double your energy bill. You don't seem to grasp that. And the cables have to be armoured. Then think about trip hazard. And one other thing, a trivial point I know, but a 100A supply these days nominally 230V, not 240V. A kwh is 1kilowatt per hour. A 24kw supply can supply 24kw every second, 24kwh is just 24kw continuously for an hour. (23kw if you prefer, changes nothing) I have no idea why you find this complicated. Yes of course charging your car will increase your energy bill as will filling it up with petrol.  This is a cable cover, they already exist, they are widely used, they do not present a trip hazard, they do not require armoured cable inside them. I kW is a rate. And the cable cover isn't even the correct colours. Or size. |

Get in touch with the manufacturer then, I believe Screwfix sell them or. www.theworkplacedepot.co.uk/cable-protectorsOh and stop posting irrelevant crap or I'll start ignoring you again. |

Far from yesterdays news. This should be a bloody major concern those who try and makeout that they care for the enviroment. So far not 1% of litheum or cobalt has been extracted from these ticking timebombs. And you still have failed to address the ECO damage caused by cobalt extraction and mining. And yet you claim to care for the enviroment what a strange warped logic you portray. . A dead lithium battery does nothing at all. It is the attempt at extracting lithium that cause fires. And as i linked new methods are being tested as we speak (Good old science) I have addressed the environmental damage from cobalt and lithium mining twice now, I will add it to my stuck record answers. My answer was that: While open mining for cobalt harms the local environment (Just as does oil extraction, coal extraction, copper extraction etc etc ad infinitum) this local environmental damage is far less critical than the global damage being done by increased AGW. Do you care about anything? You'll notice I've stopped asking you about the 12million tons of EV batteries you said were dumped, we both know you made that up and you have made no attempt to prove different, so I've moved on. As per usual you are the one being absurd. And as for science you have done no research on the matter whatsover and just doggedly cling on to the same old mantra..And as for the tons of batteries that are thrown into the landfill why should I repeatedly have to give you the links when you yourself dodge just one question put to you by others. |

Like hell he does. |

At last a decent question. The UK currently imports around 10% of its energy. Nothing wrong with that we import 46% of our food without concern. However as demand rises across Europe from EV charging this will become a challenge. Energy usage has been dropping year on year since about 1980 due to low energy products and this will continue. So dealing with the shortfall involves a multi strategy response. I have mentioned a few things like smart energy, overnight charging when supply is the same but demand lower, etc. Its quite interesting reading, but I'm pretty certain you are not that interested in the answers. Pacifico highlighted the idea of drawing back unused energy from EV batteries, but this is more to do with smoothing out supply and demand as e move towards more renewables, rather than filling any shortfalls. I have given you decent questions. There are several reasons for energy use has changed over the years. Much of that has been the demise of industrial plants. Part of it too, is energy efficiency. I did a lot of work on that and got business from it particularly in the water industry. Get the efficiency up to 95% and the project is yours. I also designed and manufactured paper mill projects. These were unity factor systems to get the best system efficiency. Real answers in my case. |

I would love to see an EV attempt this...
Faster acceleration in an EV and other than that it was just a good strong pickup truck suspension system. You are a scientist aren't you? Because no prick would ever trust one to do a real job...They can't even tow a decent size trailor whithout a mobile powerstation that's why |

This is supposedly the strongest EV for towing....What a bloody joke. The Hummer EV tips the scales at 4.5 tons, making it the heaviest consumer vehicle in the GM stable. The Ultium battery pack has roughly 210 kWh of capacity, making it the biggest pack on the market. Significant curb weight limits driving range despite the giant battery pack. Range is impressive, but there's a catch When GMC announced the Hummer EV more than a year ago, it led with impressive stats: 1,000 horsepower and more than 350 miles of range. GM has since hedged the range figure, with a slightly lower figure of 329 miles after submitting testing data to the EPA. That data also notes the usable capacity of the Ultium battery is right around 210 kWh, which is far larger than any other pack we've seen so far. Given the immense capacity of the battery pack, why is the Hummer EV's range — and the 47 mpg-e combined rating that C&D calculated from the test results — relatively low? The answer is in the Hummer's curb weight. www.edmunds.com/car-news/2022-gmc-hummer-ev-range-battery-pack-and-weight-revealed.html |

"Energy usage has been dropping year on year since about 1980 due to low energy products and this will continue".
How will our electrical energy usage continue to drop when all our heating and transportation demands switch to relying on the national grid rather than petrol stations and gas mains?

Who is liable if someone trips and breaks their leg? The person who tripped. If something is not designated a trip hazard then you cannot claim it caused you to trip. Even in this safety mad world you still have to look where you are going and any rise less than 20mm is not considered a trip hazard. By who? "Staffordshire County Council does not permit any cable to be placed across the public highway. A power cable trailing across a footway is a potential trip hazard (this includes using a cable protector or ramp) for disabled and vulnerable people. If someone tripped and injured themselves, you could be prosecuted and there may be liability under civil law." |

I thought I'd implied that, apologies if I didn't. Its also currently illegal to have a boom wire over the pavement. Re trip hazard height. The pavement trip hazard height is 1 inch (25mm) and it is just as important to show this as clearly as possible. To win compensation for your injuries, you must be able to show that the pavement trip hazard height was more than one inch in depth or height. www.accidentclaimsadvice.org.uk/pavement-trip-hazard-height/#:~:text=The%20pavement%20trip%20hazard%20height%20is%201%20inch%20and%20it,inch%20in%20depth%20or%20height. |
