New method to display the cost of electricity use

Hi everybody,

Just wanted to let you know that our team devised another method to display the cost of electricity use in campus buildings. This is intended to help those who don't grasp the true meaning of MMBTU consumption understand the relationship between OU's electrcity consumption and each building's efficiency/consumption habits.

Assuming OU's current electrical rate is $.04/kWh (as provided by Ron Chapman), I multiplied the kWh totals for each building (on South Green at least) by $.04 to get the total amount spent in the FY(06-07).

Next, to show how each building's electrical efficiency and use habits affect the cost, I divided the total amount of money spent for each building by its GROSS square footage to illustrate $$ spent/SQFT in the 06-07 fiscal year. This seemed to correspond wonderfully with the MMBTU's / SQFT I wrote about the other day.

If you have any suggestions on how this method could be improved or modified, please let me know.
