dstaley need some help proving CFL's are more efficient than incandescent:
I'm doing some research on how much money one can save by switching to CFL's in their home. I used my test group, an array of several incandescent bulbs ranging from 40watts to 60watts, and tracked their energy usage using my electricity meter outside my home. Thing is, I'm not quite sure what to do with this number.
I have an older meter, the one with the spinning disk. I tracked how long it took for the disk to spin while only the incandescent lights were on. It took 30.2 seconds to spin around once. I made sure that the only thing that could possibly be drawing energy were those lights. The Kh factor for my meter is 7.2.
Now, I have no clue what to do with this information. I'd like to see how much energy running incandescent lights take compared to CFL's, and how much money I would save by switching to CFL's.
