I use gexa and its about 9cents a kwhr. I have a newer home built 5 years ago, so its pretty energy efficient. There are a couple little things I need to do since I do feel the warm air coming through a crack in the back door, and I am also wanting to put in solar screens. Here are some of the statistics on my system also 2x250w for 7.5 hrs 2x110w VHO for 10 hrs. 2x vortech mp40s, skimmer, ca reactor all run by a reefkeeper. House is kept anywhere between 76 and 78. Ceiling fans are on 24/7 in 3 of the rooms, and the energy cost would be lower but I keep the TV in the bedroom on 24 hrs a day for the cats and I cant sleep when its too quiet in the house, yeah I know I am wierd. My last house was an electricity sponge, I lived in an 800sqft beach house 12 feet off the ground and my monthly electric bill was 500-600 a month. The insulation was nonexistant. I think the key to keeping the electric low is the effective cooling of the house, open floor plans, non carpet flooring, using CFL or LED lights throughout the house, Balanced A/C system(this gets overlooked all the time, where the loads are completely off in the house, should only be a 2-3 degree difference from room to room). My g/fs parents house was built about the same time ours was, they put solar screens on their house, every window just not the sunny side of the house, french shutters and keep their ac at 75 and their bill is lower than mine. Plus she is OCD and cleans 24/7.
