ADEME global EcoBilan of the electric VS thermal car
published: 20/06/14, 11:27
The ADEME published in November 2013 a comparative global comparison of the electric car vs engines gasoline and diesel ... which joins the long discussions we had on this forum there are already some time.

Electric vehicle comparative life cycle analysis - thermal vehicle
Development according to LCA principles of energy balances, greenhouse gas emissions and other environmental impacts induced by all sectors of electric vehicles and thermal vehicles, segment B VP (multi-purpose city car) and LCV Horizon 2012 and 2020
Summary :
In the face of global challenges such as climate change or energy dependency, but also to local challenges such as improving the quality of city air, the vehicle
electric can be of real interest. Global car manufacturers are starting to implement this new mobility solution and governments are offering incentive schemes for the development of the industry.
In this context, the ADEME commissioned a study to establish a comparison of the environmental assessments of electric vehicles and gasoline and diesel fuel vehicles.
The study carried out is a classic life cycle analysis, supplemented by a perspective of the results on two key topics: local nuisances and critical materials.
The primary data were collected from a Technical Committee bringing together the different stakeholders of electric mobility. This committee is composed
Thirty or so members bring their expertise, provide the data necessary for modeling and validate the hypotheses proposed. The obtained results
are analyzed according to different scenarios in order to qualify their ranges of variability. Finally, to account for the perspectives of technological evolution, two time horizons
are considered: 2012 and 2020.

(...)
An electric vehicle and a diesel consume a total of as much primary energy as each other (a little more for a gasoline car): thus, no energy saving to expect from the electric car. The manufacture of the vehicle represents 20% of the total in the case of diesel, and 37% for the electric one.
And the impact on the climate? Everything depends on the source of electricity
With the German electricity, resulting from more than 40% of the coal, an electric vehicle emits about as much CO2 as a diesel vehicle on 100 000 km, or 10% less if it rolls 150 000km, admitting that There is no need to change the battery in the meantime (which remains doubtful).
The balance sheet is a little better for the electric vehicle in other European countries, given the nature of their electricity. But to find a real difference, you have to come to France. With 76,5% of nuclear power in 2012 (74% in 2020, according to the ADEME scenario), the electric vehicle will emit 55% of CO2 less on 150 000 km. The electric vehicle is therefore only nuclear. But why not renewable energies? Because it is already very difficult to replace existing electricity with renewables, as shown by the German example, without having new uses to cover.
For Friends of the Earth, the nuclear-powered electric car is not an acceptable solution. The risks of nuclear power, the problem of its waste, the impact on uranium-producing countries are absent from the ADEME study.
In addition, the "mobility solution" offered by the electric vehicle does not hold water. According to the basic scenario of ADEME, an electric car is an urban vehicle (given the limited autonomy of the batteries), which travels 150 km in 000 years of life, or 10 km per day traveled by car in town . This is not efficient use and in itself is wasteful. The real solution exists: public transport and active circulation.
On the one hand, there must be shared vehicles, which everyone can use occasionally when a car is really useful: taxis, carsharing. For everyday urban use, public transport and cycling are the only sustainable solution. They allow, without major technological innovation, without risk taking on the environment and health, to reduce the impact of our displacements by an 4 factor in the fast delays required by the ecological transition.
