America’s high-carbon electricity grid is short- circuiting efforts to give consumers climate-friendly, electric-vehicle options.

Depending on where you live, generating the electricity to charge an electric car can produce more greenhouse gas pollution than driving a fuel-efficient gasoline-powered car.

The good news is that Americans have lots of choices to reduce the carbon footprint from their daily driving.

Anywhere in the country, an electric car is much better for the climate than the average- mileage vehicle.

But in many states, popular high-mileage hybrid and conventional gas powered cars are climate-friendlier alternatives to electric cars today, and new fuel economy standards should lead to even more climate-friendly options in the coming few years.
