Driving the Speed Limit
May 20, 2008 Awareness, Conservation No CommentsNot long ago, I wrote a letter to my local newspaper about the household financial benefits of driving the speed limit (as opposed to speeding). Unfortunately, the word limit for the newspaper’s letters to the editor forced me to focus only on the “drive the speed limit – save money” equation. Obviously, there are also energy efficiency benefits (and therefore environmental benefits) that can be gained from driving the speed limit (or, if you’re like my former esteemed boss, Dr. Ed Dalton, driving below the speed limit!). Anyway, I thought it would be fun to share my letter to the editor as this week’s blog installment. Here goes . . .
“Driving into Salt Lake City this morning, I decided to try an experiment. I decided to drive right at the posted speed limit the whole way in (imagine that!) and count both how often I passed other cars and how often I got passed. Between Exit 99 and the Redwood Road Overpass [a distance of approximately 22 miles], I was passed 36 times, while my little Corolla passed one semi, one UTA bus, and one guy fixing a flat.
Now, lest you perceive this letter as a self-righteous diatribe, allow me to confess that I am just like many of you who set the cruise control between 80 and 83 until just before 5600 West, and then reset the cruise just a smidgen below 75 for the rest of freeway trip in.
So where am I going with this? Are high gas prices killing you like they’re killing me? I’m guessing the answer is yes. So here’s a little friendly advice from a recovering speedaholic: If you’re averaging between 5 to 10 mph over the speed limit from Tooele to Salt Lake City, lowering your speed to the posted speed limit will likely save you between 5 and 8 gallons of gas a month, or at current gasoline prices between $17 and $28 a month, depending on the size and type of vehicle you’re driving. And if my math is right, it’ll put about 6 minutes onto your commute roundtrip, or about 6 minutes per day less time to watch YouTube. For more tips, visit www.fueleconomy.gov.”
As always, your comments are welcomed. A few thoughts for your consideration:
If you’re a high school teacher, if you have students of driving age, and if you integrate energy into your instruction, do you see any opportunities for students to conduct this type of energy efficiency-related analysis or experiment? It’s actually quite fun to do, and the result (I am now truly committed to driving the speed limit on the highway) is awesome! As we say in our Think! Energy program, think!, talk! (like writing a letter to the editor), and take action! (like changing a bad energy habit).
There is other information at www.fueleconomy.gov that could give you ideas for learning activities. One thing that I think would be fascinating would be to compare several different “commute to work” transportation alternatives in terms of gasoline usage and energy cost. For example, you could compare public transportation (bus, subway, etc.), carpooling (2, 3, or more carpoolers), driving by yourself to work (speeding, driving the speed limit), telecommuting twice a week, and telecommuting four times a week. The result would be a matrix of energy costs that would be quite interesting. It would also be fascinating to create some type of carbon footprint measurement of the alternatives.
When it comes down to it, energy efficiency is all about personal responsibility. So if we really want to do something about high energy costs, let’s individually Take Action!
