Fuel (diesel, specifically) in the UK is getting towards $10/gallon, so not surprising really!
2 comments

Fuel in the UK is £1.58 a litre (£1.48 at one garage I passed today, £1.61 at another, some garages are certainly profiteering)

In 2022 is was £1.89 a litre and spent most of the year over £1.60 a litre

Adjusted for inflation that would be most of the year at £1.85, and a high of £2.18 a litre

From 2011 to 2014 petrol was about £1.30 a litre. Adjusted for inflation terms that's £1.80-£2 a litre -- far less than current "highs".

The average UK car does 8000 miles and about 45mpg (uk gallons), or about 10 miles per litre. It thus costs 800 litres, or £1,260 a year.

Last year petrol was £1.35 a litre, and thus £184 a year less for the average car.

Fuel is insanely cheap in the UK in historic terms, just not as cheap as it was last year.

Why are you choosing the 2022 energy crises as your baseline? Not only your choice was arbitary but you managed to choose the year fuel was at its highest as a reaction to the war in Ukraine.

That price was not representative or typical, it was a spike. You can see it here.

Yes well people like to complain, and people have a short memory. If it were really a massive problem you would see a lot more smaller cars, rather than Range Rovers and BMWs.

We will see exactly the same thing again in a few years when people are 'shocked' that prices are rising again. And then expect the government to step in, even though on the interim they've bought a massive car on PCP rather than take some personal responsibility and buy a car that they can afford when inevitably something goes wrong.

Eh, last year I was paying the equivalent of £0.38 per liter over here in the States ($2 a gallon gas, $3.30 or so for diesel).

"Insanely cheap" for the UK to feels really strange for those of us way over here who tend to forget how good we have it.

> tend to forget how good we have it

That is an interesting perspective. We do not forget how good we have it, because we choose not to put high taxes on gasoline and diesel. Do drivers in the UK tend to forget that taxes are more than half the retail price they pay at the pump? Sometimes way over half. That is a policy decision.

In the US, roads are paid for by other taxes instead. Property taxes for local roads, and general fund monies (income, sales, and inflation) for highways. Unfortunately that hides the real cost of using the roads, and makes it harder for people to make good choices. This seems unlikely to change though.
I think it is a complicated issue. People who do not drive still benefit from having a road going to their house. Either for deliveries, or for emergency vehicles, or whatever personal transportation they do end up using. So we want to spread the cost around a bit so everyone is paying something, in a perfect world as close as possible to how much they benefit from it.

I imagine it also varies somewhat across the US. Locally, our city does not use property taxes for road maintenance, we have a pavement fee which is billed through the utilities system (same one that handles water & sewer, for example). Plus gas tax from the state. It could be argued that the distinction between the pavement fee and property taxes is subtle, though.

Depending on where this crisis goes, it’ll be interesting to see what effect it has.

America seems to have a lot of large vehicles that use a lot of fuel. The UK less so.

The tax will have played a part in this (how much?).

I hope we can get the kinks worked out. Even in many 'blue' states, we have created a situation where the road maintenance tax paid by EV owners is twice or more what the typical ICEV driver is paying. I sort of expected that in 'red' states, since punishing EV owners is a political priority, but we see that same crap in Oregon & Washington, for example.
Most of us laugh at the high taxes and prices in California, not realizing that their prices are reasonable, perhaps even cheap compared to overseas.
A lot of fast chargers are over $1 per kwh so unless you have access to home charging there isn't much room for savings.
At some stage I wonder if the UK will need to regulate the charger industry. The price gouging is wild in places. If we look at the energy content of petrol, a litre of gas contains about 9kwh of energy, or at average pump prices 1.58/9 = ~18 pence a kwh.

For sure, EVs are far more efficient at converting a kwh of energy into forward motion, but if we assume 35 mpg (9.25 miles/litre) for the gas car, we need about 970wh to travel 1 mile. A modern EV can manage a mile on ~260wh, almost a quarter of the gas requirement.

There are public charging networks in the UK averaging 92p/kwh - we know we need much less energy to move the more efficient EV, but even with this adjustment fuel cost per mile looks like:

petrol at UK average today: 17p/mi

Electric at very expensive public charger: ~24p/mi !!

At many chargers, there are no savings at all. For comparisons sake, that 92p kwh would be just 28.6p on the most expensive domestic electricity supply, and charging at home would be ~8p per mile on the worst possible tariffs.

I've probably done some bad math somewhere here, but I think the broad picture is correct.

The market should sort this out by itself, not saying regulators shouldn’t watch closely, but competition should be enough to do its thing. Cartel formation especially should be watched for vigilantly.
dpeends on the car. My Zoe does 4.8 miles per kwhr, my old car does 35 miles per gallon (or 7.6 miles per litre) petrol is currently £1.6 a litre.

Which is 21p per mile, for my petrol car

at 98p a kwhr its 20p per mile.

but in practice the electric car is 3 pence a mile for me (average car charging price for me is 15p a kwhr)

> dpeends on the car

Of course, thats why I've been clear all my assumptions are for 260wh/mi, which I think is a very fair middle ground figure to compare to a 35mpg car - one can pick far more fuel efficient gas cars for this comparison too, the possibilities are endless.

I think your numbers still illustrate the same point though; if you can't charge at home, an EV is not necessarily cheaper to fuel, and the gap between the public charger price and the cost to a private consumer with home charging is still far too big. 98p vs 15p is staggering.

oh yeah sorry it was meant to illustrate your point, that some of those fast chargers are massive piss takes.
Given that the majority of people in the uk have or can have access to home charging it's not a major problem

https://www.racfoundation.org/research/mobility/still-standi...

Wales – 75% of households have – or could have – off-street parking and EV charging England – 68% Scotland – 63%

In London, sure, most homes don't have off-street parking and ev charging, but then only half the households in London have a car

https://content.tfl.gov.uk/travel-in-london-2024-car-ownersh...

I think you're somewhat underselling the problem.

Even in Wales, 25% can't. This isn't a figure you can ignore.

And that's a hypothetical, it relies on landlords playing ball etc. then there's the social issues. On the north of England we have lots of terraces built for mill workers, these aren't owned by the richest on society. So then you're in the situation of charging the poorest more for transport. And these are necessarily on towns with good transport links (think 1 bus and hour).

Many of those "can't" won't have cars. 20% of households in Wales have no car.

Now clearly that 25% and 20% won't overlap exactly, but they will overlap a lot

When 80% of cars in the UK are electric and 20% are those households who rely on public streets to store their belongings for 23 hours a day, then sure that will be a problem

Given that there's only about 2 million electric cars in the UK, yet 18 million homes which can charge electric cars, that's a long way off.

But compared to the US home charging via a mains outlet is much more viable because it's 240v vs 110v. If you plug you car overnight you'll typically have enough charge to last you the next day.
This isn't as big an advantage as you might think, as a huge number of US homes have 240v sockets to power the clothes dryer:

> https://getneocharge.com/a/blog/identifying-your-240v-dryer-...

Almost everyone I know with an EV charging at home just reused the 240v dryer socket to avoid paying for a dedicated fast charger. It's often cheaper too to have an electrician fit a new 240v socket instead of the dedicated charger as well.

Home chargers with dedicated sockets is three phase 400v actually over here in the EU and every single home, and even relatively new apartments have that because of induction stoves.
> every single home

Let me guess, you live in Germany? :)

Three phase power is definitely not 100% in the EU. Not even in Germany, though adoption does tend to be higher than neighboring countries.

And FWIW, I find that my induction cooktop works wonderfully on plain old 240V 40A, so I do not think it is a requirement to get three-phase for that ;-).

I've been doing level 1 charging for the past 3 years or so. It is fine even in cold Calgary (albeit in an unheated garage)

Unless you are regularly doing upwards of 150 km/ day, it's fine.

The US is 240V. We split it into two 120V legs for some sockets, and not for others. Some people do choose to get by on 120V, true, but they are the minority. Usually people who do not drive often.
Most homes in US built after 1980s(?) have electrical panels with 240V.

It's used for dryer, stove etc.

Most? You mean all. 240V [0] as been the standard in the US basically since electrification started in the late 19th century. 120V has for all practical purposes never been a thing, it has always been an artifact of split-phase 240V. A deliberate choice to offer two voltages to every consumer.

[0] Okay, technically 240V did not become official until around 1967, but the split-phase design was there from the beginning. They capped it at 240V to stop the creeping up that had been going on in the earlier part of the century. This is why you still have a lot of people (not all of them old enough to have been alive in 1967, oddly enough) that refer to 240V as 220.

In tge early days they did sometimes wire 120 only houses. That was mostly done before WWII
Sure, but that is the exception proving the rule. Not quite urban legend, you can find people on mikeholt.com who have actually seen one in the wild. Usually because of some shenanigans the local power company pulled to directly connect more houses by giving each one a phase of a three-phase feed.
