There are many alternative energy sources for aviation, but the most promising ones are electric propulsion and solar power.
Electric propulsion is the most efficient way to use energy for aircraft, as it converts all of its energy into thrust. Solar power is also a very efficient way to power an aircraft, as the sun provides an abundance of energy that can be harnessed and used to power an aircraft.
