If that's a similar % of your cost/mile then it's not equivalent since the ICE needs around 4x as much energy/mile

- the ICE AC is powered by a petrol generator and the EV one is direct electric

Also I guess there's compromise fixing AC compressor to engine revs vs responding directly to AC load

So I don't know what really matters to other people, but minimising upfront cost maybe isn't such a bad approach

Sure - and more incentives for people who can't charge on own elec connection.

I just roughly checked my EV costs per mile over 2 yrs and they are depreciation: 40p, install charger: 2p (cost over 10 years), off peak elec: 2p, some long trip fast charging: 2p, servicing 3p

It seems not hard: charge all cars the same rate - wouldn't need to be so high now but could increase over time

"deathtrap" - wishful thinking?

Amazon is helping fund a $300 million build of a ballroom for the White House.

Independent bookstores are donating to food banks and organizations that help with food insecurity.

They are not the same.

This is making heat pumps a harder sell: additional renewables infrastructure costs added to electricity bill which have effect of reducing the gas price more than elec!

I live in a rural area & most folk have no problem using EVs. In nearest town would be harder for some in older houses with onstreet parking but we now have at least a dozen 230v chargers in carparks

My bladder has about a third of the range of my EV

Has anyone got a ballpark figure of how much of our elec bill goes to crown estate for offshore windfarm rental?

Recently, we switched out the old wood stove in our house for an electric one.

✅️ Heats room quickly
✅️ Not killing my neighbours
✅️ Still hygge
✅️ No ashes to clean

Win, win, win, win 🏆

Is it because thats how long it takes to talk mcsweeny round from wanting to make it labour policy asap?

... or has children who are british citizens and who receive some benefits - did I understand that correctly, british citizens being supported by the state leading to their parents being deported?

So mostly based on my school history lessons?

very good

Do you think the old Leaf batteries have worried people unduly? According to the OBDII info on my EV with battery cooling the SOH was still 100% at 4 years old, and the real range in use seems to agree with that too.

Well yes, of course they've rejected capitalism, how else are you going to change anything

In Wales, Cornwall, Edinburgh, London and so many places when most 30mph roads were changed to 20mph, people injured or killed by motor vehicles reduced by 20%+. With minimal change to journey times and £2bn saving in insurance costs it's a huge win. bit.ly/4gIBPlJ

NEW: Biofuels globally emit more than the fossil fuels they replace, our latest study shows.

The first-of-a-kind study looks at global biofuels production today and the potential impacts of government biofuel targets.

Don't know how much reminding I need but same on this tag on my trousers

Where I live the roads are slowly collapsing already with HGV use

The axle load increase he'd like would increase road wear by 40% - wear-wise we'd be better off with more journeys instead. That's not ideal of course so maybe the vehicle designers could work on this a bit more?

Don't threaten us with a good time, Daily Express.

Ah, there's always an annex isn't there!

Surely you're OK as a meat containing animal?

When I tried to estimate land efficiency of biofuel transport compared with PV+EV it was worse than your beef figure, it looked to me like horses might be a better biofueled form of transport than combustion engines

There's a slight difference in that you don't eat beef for energy - but fair to point out inefficiency compared with say poultry as source of animal protein.
With vehicles the result of carrying a load a distance is the same with electric motor or combustion engine
