Dear Porro, I’ll explain the suicide of electric cars

Last week, when I heard Von der Leyen expound the brilliant European idea of ​​banning petrol and diesel-fueled vehicles from 2035, I didn’t know whether to laugh (in thinking “what a fool”) or cry (in thinking “how badly we are. today we Europeans “).

This is a colossal nonsense which has been reached because he forgot Seneca’s teaching: “We must be careful not to follow, like sheep, the flock of those who precede us, because we don’t go where we have to go, we go where everyone goes” … I wonder, in fact, if our politicians – especially Europe – have lost the ability to inform and think as well as perhaps to connect head and brain (provided the latter is available).

In recent days, the statements by the president of the EU Commission on the death sentence by 2035 of vehicles powered by petrol and diesel have been highlighted by the media, unfortunately sometimes with satisfaction. President von der Leyen would therefore appear sincerely convinced that electric vehicles do not pollute our atmosphere, probably without ever having tried to find out about the matter but limiting himself to catching the numerous fake-News on the subject that plague the ether much more than CO2.

I recall in this regard that the Arpp (Autorité de Règulation Professionnelle de la Publicitè) deontologically considered incorrect and advertising of Renault prohibited which explicitly urged consumers to use an electric car (the Zoe) to reduce air pollution if the electricity for the recharge does not come exclusively from renewable or nuclear resourcesthe. Who knows if Macron is informed.

I also remember that currents of hundreds of Amps circulate in electric and hybrid vehicles generate non-negligible magnetic fields, and which among other things are less and less shielded by the new lightweight materials used for the production of vehicles. Before predicting and / or encouraging a greater diffusion of electric vehicles, it would be ethically correct, and necessary, to understand whether electromagnetic radiation can create dangerous interference, for example with pacemakers or autonomous driving systems. The Deputy Director of the JRC Research Center in Ispra Sustainable Transport Unit believes in this regard that in a scenario with millions of electric cars the magnetic fields generated in parking lots or charging areas could pose dangers to passers-by and residents.

But even leaving out electromagnetic pollution, the effects of which today cannot be reliably assessed, the pollution of a vehicle throughout its life cycle, assumed in 150,000 km as required by European standards, and calculated according to ISO 14040 standards. and 14044, provides the primary energy balance summarized in the following graph.

Electric vehicle

Calculated by me for a technical meeting of the Unae (national association of certification of electrical installers) held in Cagliari. The graph does not exactly coincide with the graph obtained from Ademe (Agence de l’environnement et de la maîtrise de l’énergie, today Agence de la transition écologique) which, however, does not analyze hybrid petrol vehicles and bifuel methane powered vehicles. It does not coincide, but it is very similar: my calculations are slightly more optimistic in favor of electric vehicles.

The conclusion is simple: the ranking of vehicles polluting the environment sees the electric vehicle in first place circulating in Europe with the exception of France and Sweden (EU Electric), followed by the one fueled by methane bifuel and by the hybrid petrol one. This is followed, with less environmental pollution, by the petrol-powered vehicle (which for Ademe pollutes a little more than I estimated on the basis of the Euro-6 certification standards), the electric vehicle circulating exclusively in France (the one circulating in Sweden, not analyzed due to the lack of reliable data on the general production efficiency of electricity, pollutes more than that circulating in France, but less than the hybrid one), and finally the diesel-powered vehicle. Already: the Diesel vehicle is the one that pollutes the least!

In fact, environmental pollution is not “smelled” by placing it in the nose behind the exhaust pipe, but is calculated according to the quantity (and negative quality) of the pollutants produced during the life of the vehicle, from the extraction of the materials necessary for its realization up to its disposal. It is no coincidence that the electric vehicle pollutes more than others in the production and disposal stages, especially due to the batteries and motors, especially when these are permanent magnet, even if it pollutes less during use. But less, not nothing.
