Default Wallet weight

One measurement that a lot of people use, is placing their wallet on a scale..

I don't know much about CO2, but I do like to save money.
When I look at my bills for electrical/kwh & fuel oil/gallons, I can tell how well we are doing overall.

For more precision, I try to factor in the local weather data.
Mostly, I use the average temperature data.
Weather Station History : Weather Underground
I can scroll down and click on the [Comma Delimited File] button and download for Excel.
I have found the local(Boston) published 'degree days' info isn't very useful,
since it does not seem to account for the solar gain we get on sunny days.

Using my history data, I know my daily Sanyo use is going to be about 6 to 8 kwh when the average outdoors is near 40 deg F.
When it's cloudy most of the day and 40 dF, I expect to use just under 10 kwh/day. (About 2 USD).

My point is, record some history as a baseline and then you can make changes and see the results pretty quickly..
I know from experience, that if you want good data, make one change at a time..
