yeah, i dont think quoting energy generation needed to power elctric aircraft will work the way you think it will..
using the current cars for example. big 5 seat family saloon, uses on average 10Ltrs to travel 100km, petrol has 9kw per litre. so, to go 100Km you need to use 90Kw of petrol.
my 5 seat family SUV, electric vehicle, uses an average of 20kw of electricity to go the same 100km..
90 compared to 20.... compare the carbon produced in making 90Kw from petrol, Vs the carbon produced to make just 20kw for the EV... or the carbon produced to make just 20 kw from solar, wind, hydro?
How many Kw's will be needed to move a small aircraft 100Km compared to Avgas/Avtur/Mogas? if mogas can only provide 9kw per litre?
