According to the Federal Motor Transport Authority, there are now around 1.4 million purely electric cars on the roads in Germany. A calculation by E.ON data experts based on this shows that This number of electric cars saves around 1.1 billion liters of fossil fuel per year compared to the same number of combustion cars. This corresponds to around 7.4 million bathtubs filled with diesel and petrol. By using electric power instead of petrol or diesel, significant amounts of greenhouse gases are also avoided: around 3.4 million tons of CO2 per year are saved by e-cars on German roads if they are charged with electricity from renewable energy sources. When charged with the German electricity mix, this amounts to around 2.5 million tons of CO2 per year. Thanks to the energy transition and the constant expansion of renewable energy plants, the proportion of green electricity in the electricity mix is constantly increasing.
And this is how the E.ON data experts calculated it: The data from the Federal Motor Transport Authority was used for the number of cars in Germany as of January 1, 2024 and for the annual mileage. The consumption of an average combustion car and BEV was taken from the ADAC. The data was used to calculate how much CO2 emissions and how many liters of fossil fuel battery electric cars save, assuming that every registered electric car replaces a combustion engine. The CO2 emissions were calculated by using the kilometer-dependent emissions for diesel and petrol (source: ADAC), the CO2 emissions of the German electricity mix (source: Energy Brainpool) and the annual mileage of the KBA.
