Why are there no electric planes in the world?
Electric planes need batteries with enough energy per kilogram of battery, or the mass penalty means they simply can’t fly long distances. Despite this, electric aircraft are on the horizon – but you won’t be seeing electric 747s any time soon.
Is it possible to power an airplane without fossil fuels?
It is indeed entirely possible to power an airplane — even a Boeing 747 — with non-fossil fuel. Here are a couple of ways to do that. 1. Biofuels.

Who was the first person to fly an electric plane?
Klaus Ohlmann’s flight in the e-Genius was five times as long as the first electric flight in 1973. Next year, pilots will fly an aircraft around the world that is powered by four electric motors and 11,000 solar cells on its wings.
