Quoted message said:This weekend I biked the 12 miles to work to see if it could be done.
It took around 1 hour and a half, however, I noticed this is really
not going to save me any money. The reason is the cost to replace my
1000 calories burned will be more than the $3 gas it costs me to get
to work.
I can see the benefits if you are over-weight and need to lose
weight. But someone if just fooling himself if they think they are
saving any money by biking, no?
As others have pointed out, there seem to be some problems with your
numbers. First, biking at 8 mph (from your data) doesn't burn that
many calories. Second, you're omitting all but the gas cost from
running your vehicle. The IRS figures more like 40 cents per mile, or
closer to $5 for your one-way trip. Third, it would be silly to
replace those calories by buying expensive stuff. If it's just
calories you want, eat bread & jelly.
But more important, your rationale is really a rationale for never
exercising at all! By your logic, nobody should ever use their
muscles - they should just lay around in front of a TV (or computer!)
and get some sort of power assist any time they needed to move their
body. Aside from the absurdity, the problem with that strategy is
that you'll likely send your medical bills through the roof. Just one
quadruple bypass will eat up any "savings" from your strategy.
So the point is, your body needs exercise. You can get it by jogging
on a treadmill in your basement, or by lifting heavy weights and
putting them down again, over and over... or you can get your
necessary exercise by doing something practical - getting to work.
Furthermore, if you are smart enough to exercise, you save time by
having your bike commute replace your car commute. Time in a car is
totally wasted, and then basement exercise time is wasted. Get your
exercise on the way to work. Save time overall.
Finally, there's a lot to be said for experiencing the world by being
out in it, instead of seeing it through glass.
