I can't believe how high some folks are paying for utilities. I had high bills for the hatchery. But, after dropping some $ on improvements, my utility bill for the house and the hatchery are now $200/month. That's for all the junk in the house and all the lights, filters, blowers, heating, and cooling for 125 tanks.
It took some work. I double insulated the attics, replaced all windows with double pane insulated low-E windows, injected expanding foam insulation between every wall stud, replaced all doors with insulated doors, and went to full flourescents. I don't use individual heaters. I heat the building instead. Now, even in the dead of winter, the furnace only kicks on a couple of times a day. And, only for about 15 minutes each time it does cut on.
Once we switch to passive heating, we're expecting to cut the bill by half again. And, after going to photovoltaics and the wind generator, we're expecting to drop the bill to only 10% of the original usage (as required by law). A friend of mine redid his CA home the same way. His electric bill for the year in 2008 was $43. That's after all the credits he received for selling excess power back to the grid.
