摘要
In October 2020,China announced plans to stop manufacturing and selling non-hybrid gas-powered vehicles by 2035[1].Proposed bans on sales of all new gas-powered cars were also recently announced by California in the United States(by 2035)[2],India(by 2030)[3],and many countries in the European Union(various dates)[3].Enacted to curb climate change,such restrictions seem likely to boost the prospects for electric vehicles(EVs),which are increasingly seen as the most viable alternative to gas-powered vehicles.
