For the past billing cycle, I used 5.96 therms per day. Last year I
used 6.81 per day. Average temp was 37 F both years. I have replaced
half of the windows in our mid '30's home. I think this helped. I
will replace the others this year and see if I can lower usage more.

I'm curious how I compare with others in my natural gas usage.

I used 120 therms in the past 30 days (about 4 therms per day).
HOW MANY THERMS DID YOU USE LAST MONTH?

I do realize that there are _many_ factors that affect usage but there is
only one number for your final usage. That's what I'd like to compare.
