Harmful for the climate and the environment? Again and again cars with internal combustion engines come under criticism. Instead of Diesel and gasoline engines the future belongs to the electric car; Tesla instead of a Mercedes. But the voices of these theses? A researcher of the Institute for world economy in Kiel, indicates error in the calculation of many current studies. These attest to the E-car is a positive climate balance, which is not true completely.
Ulrich Schmidt is a research Director and Professor at the University of Kiel. In a paper he claims that the E-car gives 73 percent more greenhouse gases than modern Diesel cars. Thus, it contradicts recent studies by the Fraunhofer Institute and the Heidelberg Institute for energy and environmental research. Both of these facilities attest to the E-car at the current electricity mix in Germany to a much more positive climate balance. Compared to conventional combustion engine E to cars according to them, 15 to 30 percent of the emissions.electric cars produce more greenhouse gases: This is the reason
Schmidt had been overlooked in the calculation of both studies a key point: "it does not allow conclusions on the climate balance, because the increased electricity demand associated with an Expansion of electric mobility, not taken into account." That is to say: The more E-cars on the roads are on the go, the more power you need. This in turn means: more electricity must be generated. And this comes less from renewable energy because of fossil fuels. "Without electric mobility, the increased power is not needed and one could use the Expansion of renewable energies to the reduction of fossil fuels, particularly coal," the researchers safe.
the increased energy Added to this is necessary in the production of electric cars. This should be taken into account when calculating the climate impact of electric cars, of course, so Schmidt.
according to the statements of Schmidt's, is not wearing the E-car in an energy mix with 100 percent of the fossil energy carriers to climate protection. Rather, they accelerate the global warming. This applies at least as long as the share of fossil fuels in the energy mix is about 20 percent. "According to the estimates of the EU Commission, the share of fossil fuels will be in the year 2050 at around 40 percent.
A scenario in which the electric mobility of the climate can contribute to protecting, rather than damaging the climate further, so far away," is the conclusion of the scientist. Only when the energy transition is well advanced, and the power was almost exclusively generated from renewable energies, was Schmidt, according to the E-car more environmentally friendly than modern Diesel vehicles."
