Electric car
The advantages are obvious: zero emissions on the site (as long as it is in electric mode), simpler mechanics (because fewer parts are needed), the number of breakdowns is reduced, which makes car insurance cheaper, Low noise and when recharging are cheaper (1 euro per 100 kilometers).
Liquefied petroleum gas car (LPG)
It is one of the least harmful fuels for the environment, consisting of butane and propane. One of the main advantages that makes it very attractive is its low price, since it costs 50% less than gasoline, so for less than 20 euros you can recharge the deposit. These cars tend to sell hybrids, because they need gasoline to start, which increases their autonomy.
Hydrogen cars
It is also known as a fuel cell car. Its operation is very simple: the car has several tanks and several air intakes (which makes it more aerodynamic) and inside is a small laboratory: the tank is filled with hydrogen that mixes with the oxygen coming in from the outside, and it gives electricity to the car that makes it work, forming as waste water.
