Tobberone

I absolutely agree, but that wasn’t what you brought up in regards to electric cars. As for the stuff you bring up besides the lithium, EVs eat more tires, but for the rest of it, the rest can be said about fossil cars as well.

Yes, you are right, cars are bad, but if you need a car, electric is better. And unfortunately, not all places are planned to be livable without a car. And that part isn’t the fault of the car driver.

I’m not saying it is nothing, but the environmental cost of 1 car battery has to be compared to the environmental damage of 1 tonne of gasoline/year it is replacing. So 500 kg of batteries or 10-15 tonnes of gasoline for a typical car…

I’d rather that than landfill, though. Today the tree tops, tomorrow the stars, as they say:)

I honestly thought it would be bigger. Having said that, we (as in the municipality i work for) currently have 40-60 MWh sand batteries in production. The first, small and hot, one is currently charging to go into production when it gets colder. The bigger and colder battery is slated to start charging the next season.

“And you can store it for long periods, not just two hours or four hours like lithium-ion batteries, but potentially for days and maybe even weeks.”

I’m guessing here, but “for days and maybe even weeks” must be because the battery is above ground? With good insulation seasonal storage is very much in the cards.

A day care in another Swedish municipality use about 1/5 of the “normal” energy for heating thanks to a sand battery. As in 15-18 kwh/m2/year as opposed to 70 kwh/m2/year as is the current upper limit for new buildings in Sweden.

I would think that the graph would be rather different had it been “last kilometer”? I’d expect to see electricity at the bottom there.
