Researchers are calling for the conversion of all cars on the roads to electric … Know the reason

New research has revealed that nearly every car on the road must be electric to meet the United Nations’ climate targets, as engineers fear that many countries are unlikely to reach the target of 90% of electric cars by 2050, while in some countries, including In the United States, electric cars currently account for only 0.3% of the cars on the road.

According to the British metro website, in the United Kingdom, the number is slightly higher – reaching 3.1% in 2019 and is expected to rise to 6% in 2020.While current projections indicate a rise in the popularity of electric cars, experts say it is not enough to sustain the increase in Global average temperatures to less than 2 ° C above pre-industrial levels by 2100.

The University of Torontos College of Applied Sciences and Engineering has built computer models to estimate the number of electric cars needed by a large auto-dependent country such as the United States. United Nations targets, lead author Alexander Milovanov, a PhD student at the University of Toronto, said: “A lot of people think the transformation is on a scale Extensive to electric vehicles will mostly solve climate problems in the passenger car sector, while I think the best way to look at it is that electric cars are necessary, but not sufficient on their own. “

“We chose the United States because they have big and heavy cars, in addition to a high per capita ownership rate and a high per capita travel rate,” Milovanov added. “There is also a lot of high-quality data available, so we felt it would give us the clearest answers,” and the team found that the states United would need about 350 million electric cars on the road by 2050, or 90 percent.

“To put that into perspective, the overall percentage of electric cars on the road in the United States is now about 0.3%,” Milovanov said. “It is true that sales are growing rapidly, but even the most optimistic projections indicate that by 2050. , The United States fleet will be only about 50% electric vehicles. “

Daniel Posen said: “We found a new way to convert this goal into a carbon budget for American passenger cars, and then we determined the number of electric vehicles needed to stay within that budget, and the researchers said,” It turns out that it is a lot, and reliance on electric vehicles will also perform The demand for electricity increases, with the need to build new power stations and infrastructure.

Instead of relying on privately owned electric cars, the newspaper proposes a massive investment in public transportation and redesigning cities to allow more bike or foot trips. Professor Heather MacLean added: “Electric cars really reduce emissions, but they don’t get us out of having to do. With the things we already know we need to do, we need to rethink our behaviors, the design of our cities, and even aspects of our culture, and everyone should take responsibility for this.
