This looks like a job for electric aviation

Electric airplanes, like electric cars, currently have the problem of relatively short range, a problem unlikely to be greatly improved until energy density of batteries goes up by an unrealistic amount. Still… some routes seem like they’re be perfect for electric airplanes:

One Point Seven Miles. These islands look pretty windy… this seems like the *perfect* opportunity for electric aviation. Set up some wind turbines, use them to power battery chargers. Plane comes in, does its run, every now and then either charges up or swaps batteries. No need to bring in av gas.
