New German Study Shows E-Cars Worsen Global Warming
The German online Business Insider here reports on just how climate (un)friendly electric cars really are. It concludes that e-cars in Germany are “far from being climate-friendly.”
As much of the public already suspects, the electricity coming out of German outlets is still largely produced by fossil fuel plants. And so e-cars indeed leave a large carbon footprint.
Moreover, all the mining of raw materials and the massive amounts of energy needed to produce the batteries in the first place means it takes a very long time before the electric car ends up with a better carbon budget than a comparably sized internal combustion engine.
And never mind other disadvantages such as long charging times, high vehicle purchase price, and low range.
The claim that electric cars on Germany protect the climate is based on a “great miscalculation,” Kiel Institute for the World Economy finds. (PDF)
“Actually exacerbate global warming”
A new study by Ulrich Schmidt, a researcher at the Kiel Institute for the World Economy, concluded that electric cars do not contribute to climate protection, and in fact “actually exacerbate global warming if the current electricity mix is taken as a basis.”
The study found the point when electric mobility can contribute to climate protection is still “far off.”
“Based on false assumptions”
Climate activists like insisting that the future of mobility belongs to electric cars, but the Kiel Institute for the World Economy researcher says that this is not so given Germany’s current power supply mix, which still relies heavily on coal. Claims that electric cars are clean are based on false assumptions, says Schmidt.
Business Insider writes:
As Schmidt points out in his study, a complete switch to e-mobility would increase electricity demand by almost 20 percent in the German automotive sector alone.
This, in turn, would require more electricity generation from fossil fuels. Provided that availability is the same in both cases. This would considerably worsen the climate balance of e-cars.”
Schmidt adds: “Regardless of what you fill up your electric car with; from a macroeconomic perspective, it runs de facto on 100 percent electricity from fossil fuels, nowadays even 100 percent from coal. This means that electric cars do not contribute to climate protection, but actually make global warming worse.”
“40{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117} of fossil fuels in 2020”
This, Schmidt says, will remain true as long as the share of fossil fuels in the electricity mix remains above 20 percent. Business Insider points out that even the “EU Commission estimates that the share of fossil fuels will still be around 40 percent in 2050.”

The very fact that e-Cars are used during the day to get to work and back or go shopping means that their re-charge cycle is in the main over-night when garaged at the owners home and therefore using ‘Off- Peak’ electricity when the Sun don’t shine!
Storage battery to e-car battery involves a Double transformation cost during the charging cycle, over and above the transformation from roof-top solar into the local battery. The actual amount of energy stored during the day by Roof-top solar would move the e-Car just a few miles and the electricity would then not be available to power your TV or Aircon fridge/freezer, hot water, pool pump, you know all those things you don’t run during the day when the sun does shine so that your house battery gets charged!
You need a local battery that is at least 20% LARGER capacity than the e-car’s battery to re-charge it!
If you claim that wind will be used, does that mean every windless night means no e-Car charged so you get a day off?
Look at the stats about wind, the morning and evening are the best times, dead of night is often the time when the wind don’t blow!
This is as bad as the UK claim that they did not use any coal to generate electricity for two entire months. They neglected to say how much EXPENSIVE electricity they imported from the continent which was in the main produced by coal burning power plants.

This study is meaningless, as burning fossil fuels is not, and cannot, cause global warming, hence climate change.

Indeed Al Shelton,
There is a lot more to climate than average global temperature and so called ‘global warming’.
Water, moisture in the air, atmospheric pressure and the interactions of the different atmospheric layers. Add to that ocean currents, solar effects, and the many above water and below water volcanoes and that’s not everything.
It does show that this 30 year distraction (of global warming) and the concentrating on one parameter (Average Global Temperature) gives a meaningless number that keeps changing very very slightly but provides many arguments for people who don’t wish to understand this planet’s climate, or how it is changing.
