Electric car owners are like vegans. You don’t need to be able to tell one, within 30 seconds they’ll tell you.
Pam tells me that the news today has been saying there's a 30% drop in sales of vegetarian foods with many returning to a meat diet :ROFLMAO:

I like cake
genuinely , my daughter was veggie for a while so was buying random things and a beyond meat burger is actually pretty tasty. There not cheap but done on the bbq like any other burger is ok. Overally tasty as a lot of these fake things are ( overdone with flavours) but also I suffer with high cholesterol despite my small frame ( genetics ) and so I try and eat better too = no burgers sometimes

Leading scientists set out resource challenge of meeting net zero emissions in the UK by 2050


www.nhm.ac.uk

The challenges set out in the letter are:

The metal resource needed to make all cars and vans electric by 2050 and all sales to be purely battery electric by 2035. To replace all UK-based vehicles today with electric vehicles (not including the LGV and HGV fleets), assuming they use the most resource-frugal next-generation NMC 811 batteries, would take 207,900 tonnes cobalt, 264,600 tonnes of lithium carbonate (LCE), at least 7,200 tonnes of neodymium and dysprosium, in addition to 2,362,500 tonnes copper. This represents, just under two times the total annual world cobalt production, nearly the entire world production of neodymium, three quarters the world’s lithium production and 12% of the world’s copper production during 2018. Even ensuring the annual supply of electric vehicles only, from 2035 as pledged, will require the UK to annually import the equivalent of the entire annual cobalt needs of European industry.

The worldwide impact: If this analysis is extrapolated to the currently projected estimate of two billion cars worldwide, based on 2018 figures, annual production would have to increase for neodymium and dysprosium by 70%, whilst cobalt output would need to increase at least three and a half times for the entire period from now until 2050 to satisfy the demand.

Energy cost of metal production: This choice of vehicle comes with an energy cost too. Energy costs for cobalt production are estimated at 7000-8000 kWh for every tonne of metal produced and for copper 9000 kWh/t. The rare-earth energy costs are at least 3350 kWh/t, so for the target of all 31.5 million cars that requires 22.5 TWh of power to produce the new metals for the UK fleet, amounting to 6% of the UK’s current annual electrical usage. Extrapolated to 2 billion cars worldwide, the energy demand for extracting and processing the metals is almost 4 times the total annual UK electrical output

Energy cost of charging electric cars: There are serious implications for the electrical power generation in the UK needed to recharge these vehicles. Using figures published for current EVs (Nissan Leaf, Renault Zoe), driving 252.5 billion miles uses at least 63 TWh of power. This will demand a 20% increase in UK generated electricity.

Challenges of using ‘green energy’ to power electric cars: If wind farms are chosen to generate the power for the projected two billion cars at UK average usage, this requires the equivalent of a further years’ worth of total global copper supply and 10 years’ worth of global neodymium and dysprosium production to build the windfarms.

Solar power is also problematic – it is also resource hungry; all the photovoltaic systems currently on the market are reliant on one or more raw materials classed as “critical” or “near critical” by the EU and/ or US Department of Energy (high purity silicon, indium, tellurium, gallium) because of their natural scarcity or their recovery as minor-by-products of other commodities. With a capacity factor of only ~10%, the UK would require ~72GW of photovoltaic input to fuel the EV fleet; over five times the current installed capacity. If CdTe-type photovoltaic power is used, that would consume over thirty years of current annual tellurium supply.

Both these wind turbine and solar generation options for the added electrical power generation capacity have substantial demands for steel, aluminium, cement and glass

Read something similar a few years ago. You can't make it up!

what an utter load of bollox


" .... what we want to do is take off our roads, cars that don't need to be there. So those people who need to be driving and they include many of your listeners and readers who needs to be driving can do so without being stuck in traffic, actually, by having more people walk, cycle and use public transport, it means less time stuck in traffic and leads to greater productivity." ... in other words anyone who can't afford a compliant motor :mad:

"A report commissioned by Transport for London estimated that 30,000 non-compliant vans currently use the expanded ULEZ area every day. There are currently only 23,803 compliant vans available for across the UK, " :oops::oops:

no way is this tw*t gonna get voted in for another term :mad:

Don't be so sure that turd will be voted in again by his own kind....don't worry about crime just ban cars. Twat.

But not all compliant motors are expensive, my 2011 bag of sh!t Renault Megane 1.6 petrol is ULEZ compliant, it's £1500 on a good day it's lowered got a loud exhaust and makes me laugh each time I ring it's neck for the 3 miles to work. But according to Mr Kahn it's ULEZ compliant and therefor environmentally friendly :ROFLMAO: .
If what they wanted to do was remove cars from city centres as much as possible, then offer incentives like free, safe, clean and reliable public transport, incentives to get a job closer to where you live or ability to move closer to your work etc

Beyond meat isn't looking so clever now 🤣
Never saw the point why make vegan burgers taste and texture like meat when for less money you could actually just eat a regular burger and it would taste better and have more protein ect I'm not sure I know anyone who works for a living (with hands ect) or any one who lives in a colder country who is a vegan I just don't think they supply enough proteins and vitamins without chemically enhancing them
