In home energy usage:
Fans: 2 ceiling fans on 24/7, approximately 48 W/hr = 35 kW/mo.
Lights: The majority of my time at home, approximately 7 hours today, was spent in my office and bedroom, with an average of 4 CFLs on at those times, for a total of 52 W/hr. (c. 37 kW/mo.)
A/C: does not run often. It's set at 76 degrees. I live in a ground floor condo. I estimate 200 kW/mo.
Hot water: 400 kW/mo. per the sticker on the side.
Microwave: I used the microwave for 7 minutes today.
FPL shows that I average 528 kW/hrs per month over the last four months. That's a daily use of 17.5 kW/hrs. This is approximately half the energy use of the average American household.
FPL, my power company, uses power from several sources:
52% natural gas
19% nuclear
15% purchased power
8% oil
6% coal
I drove approximately 30 miles today: 15 miles each way to and from FGCU, with one person in the car.
I drive approximately 9,000 miles every year, with an average of 24 miles per gallon, for a total gasoline use of 375 gallons per year. According to fueleconomy.gov, my car puts out 5.2 tons of CO2 a year.
For the most part, my choices are those of convenience. If it's not convenient for me to make sustainable choices, then I am going to make unsustainable ones. I try to conserve fuel for economic reasons only. I believe the environmental impact of my driving to and from work, school, and the grocery store is negligible when compared to, say, a Boeing 747 that dumps its emissions directly into the upper atmosphere.
