What is the order of the mass of fuels, heaviest to lightest?

Explanation:
The main idea is how the propulsion system’s mass varies with the energy storage and engine design. A large battery pack in an electric setup adds a lot of weight, so Electric petrol is the heaviest. Diesel engines are heavier than petrol engines due to their sturdier construction and higher compression requirements, placing Petrol as lighter than Diesel. So the order from heaviest to lightest is Electric petrol, then Diesel, then Petrol.
