Hummers More Green Than Hybrids?


You may have heard of the urban rumors that argue Hummers have less of an environmental impact than hybrids because of toxic batteries used in hybrids. So are hybrids more damaging to the environment than Hummers?

The answer is a definitive no.

You can disprove most of the false claims by doing a bit of math. Regarding the hybrid battery, let’s say a Hummer is driven 200,000 miles in its lifetime. Its EPA rating is 14 miles per gallon in the city and 18 miles per gallon on the highway. Let’s be real generous and assume it is driven only on the highway at a reasonable speed, yielding the maximum mileage. Divide 200,000 by 18, and you’re talking 11,111 gallons of gas.

Next let’s calculate the Btus in that amount of gasoline and convert them to kilowatt-hours. Gasoline has between 115,000 and 125,000 Btus per gallon, so the Hummer would burn through about 1.3 billion Btus over those 200,000 miles. Since there are 3,412 Btus in a kilowatt-hour (kWh) of energy, this would convert to almost 400,000 kilowatt-hours, which, at the rock-bottom price of five cents per kilowatt-hour, would be about $20,000, or almost as much as the price of a Prius. If the energy to make the hybrid battery came from fuel oil, which has around 140,000 Btus per gallon, it would take an estimated 9,524 gallons of oil to match the Hummer’s 1.3 billion Btus. At $2 a gallon, that’s also about $20,000.
