Usually 1500-1600 with bedroom AC,s on at night. I,m here alone now most nights and this month was 1100. I put in the energy saving light bulbs and leave one on when I go out at night. Just bought an led tv which uses much less power. I will be installing roof insulation and ventilation before next summer, it will be interesting to see the difference then. Clearly at lot of you are running big AC,s all day and paying the price for that. I would definitely look at roof ventilation and insulation if were me. Even things like draft excluders under your doors can help keep the cold in.
