By my simplistic calculations electric is about 15x worse than a turbine/Jet-A.
When Harbor air was talking about electric beavers and otters I did a few multiplies and divides to see what reality looks like today when comparing a PT6 to electric and what it could look like as batteries seem to be doubling in efficiency every 9 years or so. Assuming (yeah right) thats a linear trend its 35+ years to break even and maybe 10 years away from short haul. Now I'm not sure the 8% per year is accurate but that's the longish term trend. None of that takes into account battery charging/swapping/safety etc. which are huge issues.
