Electricity mix and battery as the most important criteria
The electricity mix is one, if not all the decisive criterion when comparing the types of drive. The second: the Battery of the electric car. It is not only the most expensive but also the most environmentally harmful component of the vehicle. Most of the time it’s one Lithium-ion battery, its most important ingredient controversial because of its dismantling is. Production also requires a lot of energy and therefore causes a lot of CO2. And there it makes a difference whether a battery made in China will (like most) or in Germany, with a significantly lower proportion of electricity from coal.
ICCT: E-cars are clearly the cleanest
Study: Up to two thirds less CO2 through e-cars
A study by the Technical University of Eindhoven in 2020 also saw the Stromer clearly ahead. She went from one longer battery life and for the first time by 75 instead as often before from 175 kilograms of CO2 equivalent per kilowatt hour of battery capacity. A Tesla Model 3 came up 65 percent less CO2 than a comparable Mercedes C 220 d. Already after 30,000 kilometers be that The disadvantage of the energy-intensive production of the electric car was leveled outaccording to the Dutch researchers.
