I live about 6.5 miles from work. My car gets about 20 mpg city (and it’s city driving). So, I am considering biking to work and back a couple times a week when the weather is nice. This is Michigan, so I figure, y’know, about 6 times a year.
All jokes aside, I am presented with the following list of pros vs cons:
Use less gas
Must take a shower upon arriving at work.
Must take a shower upon arrival home (optional to the extent that I might not be doing anything else that night).
I guess I’m wondering if the greenness I gain by riding the bike (using less gas and oil) is offset by the additional water usage (and the energy necessary to heat it). Assume a 5 minute shower at 2.5GPM. At my house I have a gas water heater, about 60% efficient. I have no idea what they have at work, possibly a boiler or something.
