A new study has found that EVs offset their energy-intensive production and become cleaner than gas cars after just 3 years, according to Duke and Northern Arizona University.
Gas-powered vehicles were also found to cause at 2X as much environmental damage over their lifetimes as EVs, and said the benefits of EVs can be expected to increase in coming decades as clean sources of power, such as solar and wind, are brought onto the grid.
“While there is a bigger carbon footprint in the very short term because of the manufacturing process in creating the batteries for electric vehicles, very quickly you come out ahead in CO2 emissions by year three and then for all of the rest of the vehicle lifetime, you’re far ahead and so cumulatively much lower carbon footprint," said Drew Shindell, an earth science professor at Duke University and study co-author.
“Accelerating the adoption of battery electric vehicles is a key strategy for decarbonizing the transportation sector which will reduce future damages and costs of climate change.”
