A Small Electric SUV Produces 52% Fewer Life Cycle Greenhouse Gas Emissions than a Comparable Gasoline Vehicle
(www.energy.gov)
The emissions from the EV are largely because we've not yet gotten fossil fuels out of electric generation.
The same drop in energy needs applies to the EV too, along with sharply reduced emissions associated with manufacturing it.
Nope, that's not how physics works. SUVs are insanely inefficient. A box on wheels. 11MPG vs 50. Likewise, all electric vehicles have more mass than their engine equivalents. And that mass is constant. Aerodynamic shit cars are simple piles of metal that ingest a chemical and produce range. Not even getting into the human and environmental cost of battery production.
Gas propulsion cars need to die, no question. Only because their fuel is finite and there are much better options now. However, there is no easy Apple keynote solution. It is complex and sometimes doesn't make sense.
