Utility-bill lessons

Post by shawn » Thu Nov 09, 2006 5:25 pm

I've shown my students single bills from the electric and gas utilities, showing graphs of monthly usage. What I'd like to do now is to gather a set of diverse bills from different types of customers. What I have now are my bills from 1991 when I had electric heat, the bill peaking in the winter, and my current electric bills, use peaking in the summer. My gas bill is quite boring, using about a therm a month steadily for cooking.
I'd like to see some bills before and after insulating, auditing, adding a room, or switching to fluorescent light bulbs. Anybody have anything?
If you'd like to see the bills I've mentioned, hit reply or send me a pm/email.
