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.
