Are electric vehicles really green?

چکیده

Promoting the use of electric vehicles (EVs) is one key governmental initiatives for reducing harmful pollutants and combating climate change. But this best or most effective way to save planet? EVs are touted their eco-friendliness but they really green? I discuss five reasons question ability live up hype. The questionable green linkage includes sourcing (some which non-green); batteries (manufacturing, replacement, disposal); reliance on subsidies (which may be directed at wrong market segment); charging stations (including availability costs); whether alternatives would a better choice effects environment. Electric do exceptionally well toxins, have drawbacks such as limited driving range options, especially renters, who not usually considered when evaluating costs benefits vehicles. Electricity powering cars trucks comes from variety sources, all green. Key sources electricity generation in USA include coal, natural gas, nuclear energy, wind hydropower, solar energy (EIA, 2022a). Although coal clearly green, other also non-green components, will discussed. Coal was second-largest electricity-generating source 21.86 per cent US marketplace 2021. Natural leading generating source, claims 38.44 market. Coal, typically dirtiest varies greatly by state company. states 2021 ranged maximum 90.63 West Virginia minimum 0 Massachusetts, with average 24.38 cent. An example an company mix Michigan's Detroit (DTE) current fuel 8.1 cent, 18.7 gas 8.7 oil 0.2 64.3 (see Table 1 2). Even forecast changes through 2040, less than half total produced renewable (Riles, 2021). Renewable exempt drawbacks. minerals needed panels, turbines, power own environmental issues. extraction materials used renewables infrastructure (such copper, lithium, nickel, manganese, cobalt, graphite, chromium, molybdenum, zinc, silicon, indium, boron, uranium, arsenic, aluminum, gallium, titanium) can damage mining operations these polluted air, land, water surrounding mines. Without major modifications seem high priority within firms), environment continue impacted negatively. Furthermore, it nearly impossible produce carbon-neutral fashion because even has carbon footprint result production installation process. To determine product source's footprint, Life Cycle Assessment carried out. This assessment takes into consideration upstream downstream greenhouse emissions. Upstream emissions those that released during steps production, processing minerals, transportation, construction. Downstream resource afterwards, maintenance, disposal, decommissioning In scenario meets Paris Agreement goals, clean technologies' share demand rises significantly over next two decades 40% copper rare earth elements, 60–70% nickel almost 90% lithium. battery storage already displaced consumer electronics become largest lithium set take stainless steel end-user 2040. ( IEA, 2022, p. 5) many challenges confronting transition focus areas: social. Environmental concerns revolve around categories. First, change relates impact metals revolution Second land impacts minerals. Third management.
