carbon footprint : 83,6g Co2e/km
--> 45% batteries

energy chain :

gasoline cars :
- Extraction of gas/petrol
- Transport (by boat mainly)
- Refining

ELECTRIC cars :
- Extraction of uranium ore / hydroelectricity / energy mix +

- Transport to nuclear power plant (boat, plane or truck) =

- Turbine -

-Transport (high/low tension) =

THERMAL CARS

- 30% of greenhouse gas emission from transports, more than half of it is thermal cars
- oil production and extraction method not good either

ELECTRIC CARS

- No gas emission when driving
- Emission from electricity production
- Still way better than thermal ones per km
