An idling gas engine may be annoyingly loud, but that’s the price you pay for having WAY less torque available at a standstill.

Real answer: power density. Pound for pound, gas still contains more energy than our best batteries. The weight of energy storage is still a massive deal for anything that cannot be tethered to a grid or be in close practical proximity for frequent recharging, from rockets, planes and cars (sometimes) to chainsaws and lawnmowers (sometimes).
Do we ignore fuel distribution costs? How much fuel is required to distribute fuel to the stations? Shipping oil from high-conflict areas?
Electric is stipl very much problematic, with the coal burning. But at least it has a lot of headroom to improve, and can be produced locally.
Oh, and my fucking lungs mate.
Density is relative to efficiency, and electric wins
What i cannot understand is people trying to defend something that is clearly worse,
Googling tells me that:
So the math here says electric gives you (0.97 * 77%) 0.75 MJ/kg output and gas gives you (46 * 30%) 13.8 MJ/kg output. Plus, as someone else said, spent gasoline no longer weighs you down.
I like the idea of electric, and I want to see it replace gas as soon as possible, but fair is fair.
Technically empty batteries weigh less than charged batteries.
Not that the difference is significant enough to tip the scale though.
How do you think about hydrogen cars? They have better fuel density, and hydrogen is renewable.
The argument that I’ve heard is that electric cars aren’t actually cleaner because of the pollution caused by mining the minerals required for the batteries.
I’m sorry but I’m too lazy to dig up links to back up my claim. But you are correct in that electric vehicles pollute far more being produced than combustion engine cars, however the electric vehicles gain that back over it’s lifetime if your charge from mostly non-fossil sources. The figures I have read says that over the lifetime of a car, electrics output 70% less CO2 than combustion cars, and that includes the production of each of the cars.
Thing is that pound of gas is gone, that pound of battery is still there and ready for recharge.
A dead battery is far worse than an empty jerry can, atleast the jerry can is light. Hell there are even some real nice collapsible ones and thats not even accounting for fuel bladders. Electric is useful but it is also rather rigid as well.
A pound of dead battery doesn’t help me when I’m camping 10km from the nearest access to the power grid. (There are actually powerlines not even a kilometre from my favourite campsite, but those are going to be measured in kV, and so aren’t really useful to me.)
Now, if I had enough solar panels in a mobile setup, probably folding out of a trailer, I could make it work, but solar panels are expensive.
But solar panel costs are falling way faster than battery costs.
Sure, but even then there are plenty of cases where a solar panel doesn’t make much sense either. If you’re cutting down a tree in the woods, would you rather grab your gas-powered chainsaw out of your truck and cut down the tree, or grab your solar-powered chainsaw out of your truck, spend minutes setting up solar panels to pick up the small amount of sunlight which makes it to the forest floor, and then cut down the tree?
The point is there will always be a market for ICEs until there are batteries with competitive energy density to gasoline. You don’t see solar- or battery-powered trains or construction/mining equipment because these things need huge amounts of energy to work, energy which can be easily stored in a fairly small fuel tank (which can be quickly topped off when necessary).
Absolutely, just like there’s some things a horse can do that a car just can’t.
I don’t plan on buying a horse or needing to do those things, and I don’t think the vast majority do either.
The end result is that there will still be ICEs in niche applications, but those who know how to operate them and the supply chains that currently make them cheap and dominant will slowly die off.
