For most of the values, I looked at the labels on my appliances. My minifridge, for example, listed the current and voltage as 1.4A and 115 V, so I could then calculate the power used from there. I also found an extremely handy site from the government, Estimating Appliance and Home Electronic Energy Use, which lists the average power for most appliances. For calculating the energy I used on the elliptical at the gym, I did some research and found this article on Slate.com, where it states that "On average, a treadmill uses between 600 and 700 watts of energy....But even at maximum resistance, [ellipticals] require six to seven times less energy than treadmills." I'm sure that there were some things I forgot to record in my list of times that I used electricity, but I think this goes to show how much we don't even think about the amount of energy we use everyday.

Personal daily energy consumption log (approximate)
I calculated the energy consumption for all usage that I had some control over - turning on lights, doing laundry, etc. I didn't factor in energy consumption for times that I was out of my room (in the dining halls, in class, in the library), so increasing my calculations by around 100 Watts would probably be more accurate.
