Greenhouse Gas Emissions of Electric Vehicles
In a recent post, we refreshed the notion of why driving an electric car is a better choice for the environment, even in areas that rely on fossil fuels for most of their electricity generation: in one word, efficiency. An electric vehicle is 3-4 times better at converting energy to miles driven compared to a combustion engine. In New England, the average electric car emits 73% less carbon dioxide (CO2) than a gasoline car on a per-mile basis. The emission reductions are even greater in the Massachusetts communities – and soon Rhode Island communities – that have adopted the model of green municipal aggregation.
Furthermore, a recent European study has concluded that electric cars are a better option for climate in 95% of the world already on a lifecycle basis, which includes manufacturing and end-of-life processes. While battery production certainly has environmental impact, there is a growing number of applications to give batteries a second life, turning a conundrum into opportunity, further reducing waste.
