Electric cars also have impacts arising from the manufacturing of the vehicle.[46][47] Since battery packs are heavy, manufacturers work to lighten the rest of the vehicle. As a result, electric car components contain many lightweight materials that require a lot of energy to produce and process, such as aluminium and carbon-fiber-reinforced polymers. Electric motors and batteries add to the energy of electric-car manufacture.[48] There are two kinds of motors used by electric cars: permanent magnet motors (like the one found in the Tesla Model 3), and induction motors (like the one found on the Tesla Model S). Induction motors do not use magnets, but permanent magnet motors do. The magnets found in permanent magnet motors used in electric vehicles contain rare-earth metals which are used to increase the power output of these motors.
In a study released in 2012, a group of MIT researchers calculated that global mining of two rare-earth metals, neodymium and dysprosium, would need to increase 700% and 2600%, respectively, over the next 25 years to keep pace with various green-tech plans.[49] Substitute strategies introduce trade-offs in efficiency and cost.[48] The same MIT study noted that the materials used in batteries are harmful to the environment.[50] The mining and processing of metals such as lithium, copper, and nickel requires much energy and it can release toxic compounds. In developing countries with weak legislation and/or enforcement thereof, mineral exploitation can increase risks further. As such, the local population may be exposed to toxic substances through air and groundwater contamination. New battery technologies may be needed to resolve those problems. Potential battery technologies that could one day replace Li-ion batteries are the aluminum-ion battery and the sodium-ion battery, but for the moment recycling of these is not any better than the recycling of li-ion batteries. Li-ion batteries recycling is rarely done in developing and developed countries.[48] In fact, in 2017, only just 5% of lithium-ion batteries were actually recycled in the EU.[51]
The in bold is why they want electric cars I guarantee politicians already know if this starts where to invest! It's always about the money and never about the environment!
A report published in June 2011, prepared by Ricardo in collaboration with experts from the UK's Low Carbon Vehicle Partnership, found that hybrid electric cars, plug-in hybrids and all-electric cars generate more carbon emissions during their production than current conventional vehicles, but still have a lower overall carbon footprint over the full life cycle. The higher carbon footprint during production of electric drive vehicles is due mainly to the production of batteries. As an example, 43% of production emissions for a mid-size electric car are generated from the battery production, while for standard mid-sized gasoline internal combustion engine vehicle, around 75% of the embedded carbon emissions during production comes from the steel used in the vehicle glider.[52] The following table summarizes key results of this study for four powertrain technologies:
