Converting to EV alone will not help you achieve your climate goals: Analysis

As automakers around the world compete for full electrification to take a positive stance on climate change, a study shows that switching to electric vehicles alone will not meet environmental goals. Based on an article published by Nature Climate Change, switching to large-scale electric vehicles will not help the environment in the way that motorists and consumers want it to.

A team of research engineers from the University of Toronto conducted a study of the United States as a market for studies. The selection was made based on the high vehicle ownership per capita and the high travel rate per capita. The team designed computer models to calculate how many EVs would be needed to keep global average temperature growth at 2 degrees Celsius from previous levels in the industry by 2100. During the process, they calculated a budget called the carbon budget to determine how many EVs would be needed to continue in that budget.

As a result, the U.S. should have about 350 million EVs on the road by 2050 to meet its emissions targets, which is about 90% of all vehicles at the time. The main author of the article, Alexandre Milovanoff, said that the proportion of electric cars on the road today is 0.3%. According to Phys Org, “it is true that sales are growing rapidly, but even the most optimistic forecasts suggest that by 2050 the US fleet will only be in the EVs at around 50%.”

The study also stressed that regardless of the preferences of consumers of electric vehicles, technological barriers such as the development of electric infrastructure will put pressure on the country’s green plans. According to the paper, these 350 million EVs would increase annual electricity demand by 1,730 TWh, which is about 41% compared to current demand. And this can only be achieved through massive investments in infrastructure and new power plants, some of which can again run on fossil fuels. The team also concluded that the technical challenges that could arise from the supply of materials for lithium, manganese and cobalt batteries make this goal quite unrealistic.
