The Forbes website recently published an article saying that in some carbon-intensive power generation areas, the carbon dioxide produced by electric vehicles throughout the life cycle is no different from traditional cars. At the Model 3 new car launch earlier this month, Tesla CEO Elon Musk once applauded “sustainable development†and “reduces CO2 emissionsâ€. But in fact, in some areas, the carbon dioxide produced by electric vehicles throughout their life cycle is not much different from traditional internal combustion engines.
Before most of the electricity was generated from clean, renewable resources, the idea that electric cars would save the planet was just empty talk. This view comes from Bernstein Research, which recently conducted research on the automotive market in Hong Kong. According to Bernstein Research, the power generation methods in Hong Kong and the Chinese mainland are carbon-intensive. In other words, coal is mainly used to generate electricity. Electric vehicles not only do not reduce pollution, but also increase pollution.
Bjorn Lomborg, author of The SkepTIcal Environmentalist and Cool it, says a Tesla Model S electric car is In the life cycle of 150,000 kilometers, about 13 tons of carbon dioxide is emitted based on the electricity consumed.
In addition, the production of batteries will generate an additional 14 tons of carbon dioxide, and other production and dismantling processes will produce 7 tons, a total of 34 tons. This is equivalent to the carbon dioxide emitted by the diesel version of the Audi A7 Sportback throughout its life cycle, which is about 35 tons.
Neil Beveridge, an analyst at Bernstein Research, said that because Hong Kong's power generation is carbon-intensive, the carbon dioxide emitted by electric vehicles during the 150,000-kilometer life cycle is equivalent. More than 4.4 tons or 20% of gasoline cars with comparable performance.
In this set of data, Beveridge used to compare with the Model S is the BMW 320i. The BMW 320i is powered by a two-liter engine that is not on the same level as the Tesla Model S, but is a direct competitor to the Model 3.
Beveridge said: "Although electric vehicles may be part of a long-term solution, it currently poses more problems. In areas like Hong Kong, affected by carbon-intensive power generation, electric The amount of carbon dioxide in a car is 20% higher than that of a conventional car."
Musk also said in January that Hong Kong may lead the popularity of electric vehicles around the world. Lomborg also believes that not only Hong Kong is a carbon-intensive power generation method, but also in mainland China. This type of power generation inherently pollutes the environment and encourages electric vehicles to further pollute the environment. Therefore, subsidies for electric vehicles may not be suitable.
