| 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. |

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. | |

| ▲ | tialaramex 36 minutes ago | parent [-] | | 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! |

| 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. |

| ▲ | robocat an hour ago | parent [-] | | 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. | | |
| ▲ | titzer 18 minutes ago | parent [-] | | 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. |
