'Electric car only greener than car on petrol after 700,000 kilometers'
Electric cars are better for the environment than cars on petrol, but the turning point is much higher than expected. This is shown by calculations by a professor from the University of Liège.
In doing so, the professor assumed the current state of electricity production, which only for a small part comes about in a 'green' way. The production of electric cars and their batteries has also been included. Read also
At the moment, an electric car of 60 kilowatt hours (kWh) consuming 20 kilowatt hours per 100 kilometers would have to cover exactly 697,612 km before it is greener than an average petrol car that consumes six liters per 100 kilometers. This is what the Autogids.be website reports.
The calculation was carried out by Professor Damien Ernst, specialist in energy issues at the University of Liège, at the request of the RTBF program Auto Mobile. The professor has used scientific literature to determine the different variables.
We mention a few elements: the energy it takes to make the batteries: 18,696 kg of CO2. The European average of CO2 emissions per kWh: 11 kg CO2 / 100 km and the CO2 emissions of the petrol vehicle: 13.68 kg CO2 / 100 km.
This ultimately leads to this distance of almost 700,000 kilometers before the electric car is more environmentally friendly than a car with a petrol engine. However, when the electricity is 100% 'green', the electric car is already less than 30,000 to 40,000 kilometers cleaner than an average petrol car.
