On average, an electric car consumes about 20 to 25kWh of electricity per 100 kilometers. Also it is important to note that the electricity consumption depends on the charging method. When an electric car is charged from a household outlet, electricity consumption is generally higher than when using a faster charging technology such as a wallbox or fast charging system.
The average footprint for 1kWh power produced in EU causes a carbon footprint of around 250 -300 gram. CO2. Switzerland, Sweden and France have have some of the lowest footprints for electricity generation in Europa due to their reliance on nuclear power and hydropower, with emissions of around 14 and 41 grams of CO2 per kWh respectively. Countries which heavily rely on coal for electricity generation like Poland and Estonia have a much higher carbon footprint per kWh with emissions of around 700 – 800 grams per kWh.
