Ready for the electric future?

A total of 681,410 electric cars were registered in 2021. This means that the percentage of new vehicle registrations involving electric cars has more than doubled since 2020. This increase also means that an increasing number of charging facilities, such as wallboxes in the private sector, are being installed and registered with the grid operator.

From a number of 5 to 10 electric vehicles, intelligent control of the charging processes is necessary in most cases to avoid unnecessary expansion of the existing grid connection or increased power charges to grid operators.

In 2020, electric cars reduced CO2 emissions in Germany already by a good 160,000 tons if the current electricity mix of 471 g CO2/kWh (2018, German Federal Environment Agency) is used to calculate the CO2 emissions. And this figure could even have been doubled if cars were charged exclusively with green electricity – at least that is the conclusion of an evaluation conducted by the energy company E.ON which compared the CO2 emissions produced by cars with combustion engines with those produced by electric cars. But since wind and solar-based renewable energy generation naturally fluctuates, more or less electricity generated from coal and gas inevitably ends up in electric car batteries depending on the time of day, which makes it not exclusively green.
