Cleaner Electricity Grids Mean Electric Vehicles Are Really Making a Difference
The amount of heat-trapping pollution that’s released every time Bill Williams drives his electric sedan a mile down a road here has fallen by about a quarter in the three years since he bought it.
Williams’ car hasn’t changed, but the electricity that powers it has. In Tennessee, power once generated overwhelmingly by coal has given way to more nuclear and natural gas power. With the rising number of plug-in models available in the US, many at increasingly affordable prices, and with electricity getting greener, the climate benefits of electric cars are growing.
