The impact of the electric car, in comparison with the gas car, was measured taking into account the duration of use of the vehicle.
The 2016 CIRAIG study (French only) indicates that after 150 000 km, the impacts:
It is important to note, the impact of mining minerals is 25% higher when building electric cars in comparison to the gasoline equivalent. This is partly due to the manufacturing of the battery, which requires the extraction of rare metals.
The batteries of electric vehicles demonstrate a long life: 200 000 to 500 000 km. Manufacturers generally offer a warranty of 8 years / 160,000 km.
At the battery end of life, it can be reused for energy storage purposes. In the long term, the technology is rapidly evolving for the recycling of different minerals found in the battery (including graphite, lithium, cobalt) to manufacture new batteries in a circular economy. For instance, Recyclage Lithion, in Quebec, has made important breakthroughs and is expected to be in operation shortly.
Here in Quebec, 99.7% of our electricity is produced from renewable energy sources that produce no greenhouse gas emissions. This makes recharging your vehicle eco friendly especially compared to other places where electricity is produced from fossil fuels. It should be noted that at the global level, the trends show a decarbonisation of energy sources from year to year, therefore, the balance sheet should improve in this direction.
