So I got my kill-a-watt yesterday.
I have plugged the necessary data in (I think) for my spreadsheet:
Brammofan's Energy Efficiency Spread-sheet-o-maticI got the rate information (column J) from the utility's website, rather than from my bill, so that may change if I get home, find the bill, and it shows something different.
I used about $0.25 worth of electricity getting to work and back yesterday. Had I driven my Honda Pilot, I would have consumed a little over a gallon of gas. Saved about $2.42 in direct energy costs.
According to the green calculator on the Brammo site, my car puts out about 20.4 pounds of CO2 emissions every day, versus the 3.3 pounds of CO2 it takes to recharge my battery from my utility's coal-fired power plant. So I saved about 17 pounds of CO2 from the atmosphere by riding.
Pretty cool.
