Who cares about motor efficiency when you can only take 10% as much fuel. At the end of the day, cost is the only metric that matters.

The cost of EV energy (to the driver) is about half that of the cost of gas energy. And that's if you buy electricity at charging stations [1].

If you charge at home it gets less. If you have solar at home it approaches zero.

Yes, the cost of the car itself is a factor, but even there prices are dropping all the time.

>> when you can only take 10% as much fuel

effeciency makes all the difference when we discuss % of fuel. 90% of 100 mj is the same as 30% of 300 mj. So already the "fuel" can be 66% less. Generally though the raw amount of mj isn't a very important number. A better measure (which takes effeciency, and tank size into account) is "range". But even that is somewhat meaningless. At some point range is "enough". For daily commutes that may be 50 miles. For long-distance it might be 500 miles.

In only a very few cases would a pickup with 2000 mile range be more useful than one with 1000 mile range.

Plus you can also factor in maintenance costs. The cost of ownership of an ev, from a service and maintenance point of view is a lot lower.

[1] ymmv somewhat. Although electricity prices vary a lot, so do gas prices. The 50% saving (at worst) is a pretty good rule of thumb though.

Indeed, solar panels and EVs are the way of the self-sufficient rugged individualist. It's an amazing PR and marketing coup to make it the other way around and presented as something for "liberal weaklings" etc.

If there is such a marketing, then people relate to it because EVs are not suited for handling unpredictable situation. You got stuck in a ditch in the middle of nowhere at night, you loss all of your battery getting out of it, and now you are stuck. So you can't take it to unforgiving places.

EVs are great for boring commute that is it. I don't see it changing any time soon.

Right, the set of people who actually pump their own oil out of the ground, refine it into something you can put in a modern vehicle engine and drive around on that is likely zero, but the set of people who own panels and storage so they can fill their EV includes my team lead, who is just some guy on a pretty average salary living on a modern housing estate.

The bio-fuel people at least make some kind of sense compared to fossil fuel "survivalists" - but again they're portrayed as just tree huggers!

Before the Iran war, I did a back of the envelope calculation for the price of gas of your average ICE for a certain fixed range vs. the price of electricity an average EV uses for the same range. This was under the assumption that you buy electricity at a random charging station that you don't have a contract with.

Based on these average values I used, EVs fared slightly worse.

This was not factoring in costs of purchase or repairs etc. And all averages were taken off the internet so everything had to be taken with more than a grain of salt. But the outcome was nowhere near your statement of EV energy costing about half of the cost of gas for the driver.

I've only had an EV 3 months now, but it'll never see a charging station.

I pay around $.12/kw and get 4 miles per kw. So my "energy" costs are $.03/mile. I have a Mazda cx50 as well, it gets about 20-22mpg, with the gas prices here in Seattle that's around $.30/mile. Even where gas is cheaper that's still $.20/mile. Literally 10x the cost to run a gas car vs an EV.

I'm honestly shocked at how many people have EVs and rely on charging stations. I mean, I think it's a low number, but the fact that it's more than zero is shocking to me.

> buy electricity at a random charging station

Well there's your problem. Try doing the same calculation with the average residential electricity cost. Most car use is for commutes after all, so most people can just charge their EV in their driveway every night.

Destination charging and rapid charging are notoriously expensive. It's a luxury product intended for a once-a-year road trip. It is not even remotely representative of your average charging cost. Street-side charging is slightly less excessive, but you're still paying a serious premium.

reply
> so most people can just charge their EV in their driveway every night.

That does presume that those "most people" have a driveway where they can do charging. I.e., all apartment dwellers with cars in parking lots/garages (excluding those few that may have installed electrical plugs at each parking spot) are cut off, as are city dwellers without driveways who park on the street (or in another garage, again without electric hookups for charging).

Yes, eventually those garages and parking lots will likely include some form of "car charging" infrastructure, but until that happens, "most" is not as big of a percentage as that word makes it appear.

We just bought our first (used) EV, and charging stations are the Wild West right now. Any random station you pull up to might charge close to the local cost of electricity, or some wild sky-high amount. And hopefully they’ll tell you what that is before you have to swipe your card. There the economics can swing towards gas cars depending on how absurd your local charging station prices are. For people filling their tank every couple days because of a 2 hour commute or something an EV may still not make sense financially. But if you’re putting in under 40 miles and have even a modest 120v 12 amp circuit you can plug into at home (e.g. a dedicated washing machine circuit) you’ll likely only need a charging station on rare occasions such as a road trip. As a matter of fact I am writing this from our first EV road trip. The inconvenience has been comparatively minor and our “fuel” costs should end up being about half of what they would have been in our hybrid SUV.

Doing the equation regularly would be interesting.

There are some other parameters to consider too. Stopping for fuel is not something I enjoyed. I can charge at home. You won’t have to stop to refuel in an EV unless you’re going a long way. If you’re going a long way the stop will be longer. Much worse.

You won’t service an EV much, that’s nice.

The silence is bliss.

Were you using DC fast charging stations or level 2? Fast charging is about 2x the price.

My xpeng g9 goes about 570km in summer. Less in winter, like 480 maybe. Longest range ICE i had was a mercedes wagon that went 1050km on one tank of gas.

Filling the wagon today would cost me like 170 euro. Filling my xpeng happens overnight and is about 7-9 euro depending on grid pricing.

> cost is the only metric that matters.

Negative externalities like pollution and climate change are not even priced in. Even if they were priced in, there are non-monetary factors that we could consider once in a while, but the conversation tends back to dollars.

reply
Many countries have high fuel taxes that approximate pricing in the negative externalities.

Assuming you think price as a signal is the solution to dealing with those externalities, it doesn't matter what caused the price to be high.

reply
Fuel taxes are "in theory" the mechanism to price these in, but today, they are not, and how this money eventually has the opposite effect! Revenue from fuel taxes is usually funneled to more transportation infrastructure (> 80% to road construction in the US, only 15% to mass transit). The vast (and ironic!) indirect effect is more cars, more car miles, and more consumption--a long-term, indirect subsidy to fuel and auto industries. Approximately zero goes to regulation enforcement (like emissions inspections and other enforcement), which is funded by usage fees and general income taxes.

The commenters above, is the answer to your question. Based on their discussion, there are metrics besides cost that matter to them.

Not everyone is you.
