Nothing so far electric has come anywhere close to the energy density of kerosene, and given how important it is for planes to be as lightweight as humanly possible, expect kerosene to remain in use for many decades to come. Unless, of course, a revolution occurs in battery technology that makes them more energy dense than kerosene.
