Why scrap a cheap power source for a marxist concept that simply will not work?
Electricity is Marxist? Now there is a new one for me. I never read Das Kapital - perhaps I should.
Electricity is a pretty ideal way to power a vehicle for all kinds of technical reasons. That is why the rail companies think it a good idea to string out tens of thousands of miles of very expensive copper cable around the World. For an aircraft, electrically powered fans would be almost certainly simpler, cheaper, lighter and safer than current turbofans.
The problem is when you have to move away from a wired supply. The storage of electricity at a density anywhere near comparable with hydrocarbon fuel is looking increasingly like an intractable problem. Generations of major investment has upped power density by a factor of about 5 from classical lead-acid batteries. A further increase of a factor of 50 is needed when in fact we seem already to be into a curve of diminishing returns. Forget the politics - that is the reason we may never see a practical all-electric aircraft.
