100 things to save the planet 004
Apr. 22nd, 2012 12:47 pmAccording to tests cited in The Ten-Minute Activist, the most efficient highway speed is 55 miles per hour. That'll save you up to fourteen percent of your gas, if you habitually drive faster than that. Driving more safely—slower acceleration, slower braking—could save you more than thirty percent. And if you expect the car to sit still more than a minute, turn it off; that could save you up to nineteen percent. I don't know where they're getting their numbers on the gas mileage bit, but the rest makes sense. And saving gas saves money as well as CO2 emissions. So, drive safe!
