Halving Our Electricity Use from 2005 to 2007 - The Graph

In an earlier comment on this blog, LNeumann has mentioned that "We have already decreased our electricity use from last year...." Here's the proof, taken directly from our last utility bill with the local Hydro company (our next bill should be coming from Bullfrog Power). The most recent data is shown on the left, and the oldest data is on the right in this graph.

Arguably, the Jul-05 and Sep-05 spikes (and the smaller ones in Jan-06 and Mar-06) are exceptions to an overall declining trend in electricity use. As I mentioned previously, we have adjusted the thermostat to reduce summer-time air conditioning. In the winter, our house is heated with a forced-air gas furnace. But with less daylight, electricity savings from using Compact Fluorescent Lights (CFL) may be more noticeable than in the summer. The bottom line is that these and other efforts (such as not using our electric clothes dryer as often, and reducing electricity leaks) are paying off!

Unfortunately, our water use has remained almost unchanged, so we will focus more attention to conserving water in coming months.
