1. Battery production, like any production, has an environmental impact - but the motivation for battery-electric vehicles is to eliminate local environmental impact (e.g. urban centres). If all of the pollution happens at a single source then it's easier to contain, reduce, and eventually eliminate. 2. Diesel fuels are still very dirty - and the reliability of petrol engines is not a big-enough problem to justify switching to diesel engines - and ICE cars have far more moving parts compared to BEVs than just the engine. 3. Tesla did look into fast battery-swap stations that can swap a battery in less time than it takes to fill a gas tank - they stopped further development due to a lack of consumer interest: users are perfectly happy to charge at home overnight, when the car's aren't being driven anyway, and when electricity is often cheaper at night. As more use-cases switch to electric there will be an impetus to adopt battery-swapping, but it remains an option. 4. 24-hour solar is possible with energy-storage, which is what Tesla is looking into, but again, the point of BEVs is to first eliminate local pollution, then make it easier to eliminate energy source pollution thanks to the fungibility of electricity and centralisation of pollution sources.
