Yeah I don't trust their accuracy at all.

Last winter my gas heater was out of commission for about a month. I plugged in 3 oil filled electric radiant heaters. I had guests at the time so I kept the temperature up higher than usual in areas of the house which I normally keep cooler. It all worked out great.

The next power bill showed that most of my power usage was "lighting." Uh huh.
