THEelectric car pollutes more than that a gas or Diesel? False, completely false. Two important scientific studies have dismantled this persistent fake news, demonstrating with data in hand that i electric vehicles They are clearly more ecological considering the entire life cycle.
Two studies, a conclusion
The first study, published by Bloomberg New Energy Finance (Bloommergnef) last March, analyzed Five main car markets (Great Britain, Germany, the United States, China and Japan). The conclusions are unequivocal: the total CO2 emissions in the entire life cycle of an electrical vehicle of medium segment are 27-71% lower Compared to an equivalent car with endothermic engine.
The second study, published by Nelson-Mobilityconfirms this advantage, highlighting that electric vehicles can reduce carbon dioxide emissions up to 80% in regions where electricity comes mainly from renewable sources such as hydroelectric.
The truth about the complete life cycle
It is true, during the production phase An electric car generates multiple emissions – about 6.57 tons of CO2 against 3.74 tons of a thermal car. The battery is responsible for almost half of the initial carbon donation. But this initial disadvantage it is quickly compensated.
After just 30,000-40,000 km traveled, equivalent to 2-3 years of average use, the electric car equal the emissions balance and begins to be more ecological. Considering that the average life of a car exceeds 200,000 km, the advantage becomes impressive in the long term.
The efficiency that changes everything
A petrol car uses only 16-25% of the energy contained in fuel, while an electric vehicle uses up to 91% of the energy stored in the battery. Translated in practical terms: to travel 100 km, an electric SUV consumes equivalent energy to 2.3-5 liters of petrol, while a thermal SUV requires between 6.7 and 21.7 liters.
In France, where electricity is largely produced by nuclear and renewable, driving an electric car means issuing just 120 kg of CO2 every 10,000 km, against the 1,800 kg of a thermal vehicle. A difference of 15 times.
According to Motus-e, in European countries an electric car emits in the entire life cycle between 10 and 21 tons of CO2, while thermal vehicles do not drop below 44 tons. In the United States, the difference is even more marked: 10-23 tons for electrics against 82 tons for petrol ones.
The myth of polluting batteries crumbles
The environmental impact of the production of batteries has already halved Over the past five years, going from about 200 kgco2e/kwh to about 100 kgco2e/kWh. And the trend continues to improve. On the end of life front, current techniques allow you to recover up to 95% of the raw materials present in lithium -ion batteries. Not only that: batteries can have a second life as domestic storage systems, further prolonging their usefulness.
The future is even more green
According to Bloommergnef, by 2030 the electric cars produced in Europe and the United States they will even emit 77-86% of CO2 less Compared to conventional vehicles (and 50% less in China), thanks to the growing penetration of renewable energy in the energy mix.
Not only climate: health, silence and safer guide
The benefits of the electric car go beyond the reduction of CO2. The absence of noise pollution in the city reduces the stress of drivers and residents. A study byYork University It has shown, through electroencephalograms applied to London taxi drivers, that driving electric vehicles significantly lowers stress levels.
This change in driving behavior has a concrete impact: research in collaboration with insurance companies have detected a reduction of rudeness, dangerous behaviors and abrupt accelerations to the driving of electric cars. It is not surprising that the insurance costs on average 24% less for civil liability and 18.5% less for complete coverage.
Convenience hidden in the long term
Despite the highest purchase price, considering all costs (energy, taxes, maintenance, insurance) electric cars are often cheaper in the long run. The top -up costs on average less than 3 euros per 100 km, against over 8 euros in gasoline. In addition, maintenance is cheaper than 20-40% than thermal vehicles, thanks to the lower mechanical complexity: no straps, frictions or pipes subject to rapid wear.
