Solar panels don't have zero environmental cost, I'd be surprised if making them solar powered is a net environmental win, especially when you have to build the charging infrastructure anyway, just in case the weather is not suitable for charging.
- icebraining 7y agoThe extra solar panels installed on the grid to feed those carts don't have zero environment cost either, though. And neither do the batteries required to hold that energy until the carts are plugged-in, which would likely be at dusk/night, when they're not in use. (Grid solar -> grid battery -> cart battery) involves more losses than just (cart solar -> cart battery).
