"Numbers suggest saving potential that we do not have"

If 2030 million cars drive electrically, the expansion of green electricity will keep up – or the electricity mix will be dirty again in total? Scientists write a fire letter to the EU – and the carmakers also put their fingers in the wound.

More informationhat is the politicians in the contribution of the electric car for the climate fundamentally offset? Unfortunately yes, a group of six European scientists says in an open letter to the EU Commission. In a position paper, 170 scientists from all over the world had previously criticized that the CO2 savings effects mentioned by the EU were not realistic by switching to e-mobility in the given period. "The numbers suggest a savings potential that we do not have", said Professor Thomas Koch from the Karlsruhe Institute of Technology (KIT) of the German Press Agency. Because the electricity mix was simply calculated incorrectly.
Scientists: Strommix was calculated incorrectly
"The question is not: electric car or burner. The question is: fossil or not", said Koch. In an open letter to the EU Commission, about the "Stuttgarter Zeitung" and "Stuttgart news" (Monday) reported, expressed chef and five other scientists their concerns. Because the EU is currently tightening its CO2 guidelines for the newly approved cars in Europe.With 453.000 sold electric and plug-in vehicles in the first quarter is Europe China with 489.000 electric cars close to the heels. And according to countries, Germany is already the second largest electric car market in the world, with almost 250.000 newly approved electric cars by the end of May. VW is now one of the drivers of development. By 2030, Volkswagen only wants to sell a third of his cars with a gasoline or diesel engine. Mercedes-Benz and BMW aim a share of around 50 percent.

VW boss: Modern diesel is more climate-friendly than an electric vehicle that is loaded with coal stream"
But the corporations do not want to set a fixed date for the end of the burner. The markets and the wishes of the customers are too different, too different the political requirements. In addition, there is also the charging infrastructure that is missing in many countries, also in Europe. And because it is ultimately about climate protection, it is much more important where the electricity for the electric cars actually comes from.
With electricity from coal or oil, he does not see any great sense in the switch to electric drives, said VW boss Herbert Diess at the balance sheet PK. "A modern diesel is more climate -friendly than an electric vehicle that is loaded with coal stream", said BMW boss Oliver Zipse of the "Passauer Neue Presse/Donaukurier" (Monday). He has "great concern", whether there will be enough green electricity.

Experts say that electricity needs will continue to increase with more wind and solar systems
The EU Commission assumes that the electricity will become cleaner with the expansion of wind and solar systems. No, say Koch and his colleagues. Because the electricity requirement will increase even more – and then the whole invoice is no longer correct.The federal government wants to not only have 10 million electric cars on the road by 2030, but also quickly change industry and heating. The electricity requirement in Germany will increase from 56 to 57 gigawatts by 2030, says Koch. In 6000 out of the 8760 hours a year, in addition to green electricity, it will also need more electricity from fossil power plants. This overlooked politics in their debates and invoices, in any case not included. Then the real CO2 emissions could be much higher than estimated by politics – in total even twice as high.
Nuclear current instead of gas, oil and cabbage flow
The scientists all agree that the climate must be protected and the CO2 emissions must be reduced, emphasized Koch emphasized. "For this we also need the electric car." But the guidelines also favored the e-car where the climate is of no use.If green electricity is not supplemented with gas, oil and coal current, but with nuclear power, the invoice would be better off. But that is a political decision by the Germans, said Koch. If today’s combustion engines instead of gasoline and diesel CO2-neutral synthetic fuel, on the other hand, were saved 25 percent CO2. But even there, politics and industry went a different way today. In the interest of the climate, the EU Commission should consider their attitude again before the next step, according to the scientists’ appeal.
