Vacation Impact on Energy Consumption

We left for vacation on the 14th of May. Prior to our departure we configured the house for low energy consumption by unplugging all transformers, chargers, and other non-essential (to us), electronic equipment. In the office the only thing running is the modem, router, and the solar system logging machine. Our two Tivos are still busily recording our favorite shows. Our two refrigerators are running as well. TVs, VCRs, radios, and all other equipment that usually sits gobbling energy waiting for the chance for us to wake them up are unplugged. As a result, the first day away our house generated 117 percent of the energy it used. We sold 13 kwh back to the utility. You can clearly see the spike in the percent of energy generated in the chart below:
