> We found that battery electric cars generate half the emissions of the average comparable gasoline car, even when pollution from battery manufacturing is accounted for.
Yes, EV's have higher energy and emissions numbers embedded in their manufacturing, but that gets more than offset by the much lower emissions of fuel. Breakeven is the first 6-18 months, depending on battery size and emissions makeup of your local grid. Even in "coal-powered car" country.
> EVs are powered by electricity, which is generally a cleaner energy source than gasoline. Battery electric cars make up for their higher manufacturing emissions within eighteen months of driving — shorter range models can offset the extra emissions within 6 months — and continue to outperform gasoline cars until the end of their lives.
As for waste, there is battery recycling, but the more interesting part is second-life storage use. Battery may not have the energy density required for transportation, but you can still use them fine as a cheap powerwall-like product. Cheap because the cost of the batteries was already paid for by the first owner of the car.
