In February, it peaked at $190.00. It also hit -20 here for a week straight, and the two basement bedrooms were running 1500 space heaters balls out. (Even with the natural gas furnace, the basement gets chilly)
We were also running 4 computers full-time, and I had only replaced my 32" Sony CRT television with a 42" Hitachi Plasma the month before. Everybody had that big TV on all the time, it seemed, tuned to Discovery HD night and day.
I've since dropped the bill down to $145.00/month, by switching more of the inside lights to CFL units with less wattage and heat, forcing the computers to go into Standby/Hibernate/OFF if they're not being used, disabling the Instant-On function of the Plasma TV, and setting both fridges to a slightly higher temp.
I had a home energy audit done last month, and the utility rep gave me more ideas to get the bill down.
This month should be even better, I've limited the A/C use by using room and ceiling fans, and put up a clothesline outside - that should keep the clothes dryer from spinning the kilowatt-hour meter. I've been grilling out on the deck vs. using the stove and oven. In the hottest days of July so far, my wife and I use just the Dell notebook for email and Internet, leaving the big IBM space heaters upstairs turned off.
Next, I'm finishing the CFL conversion, and running a separate AC line from my experimental 2KvA solar/telco battery/inverter system to my office computer desk. Depending on how well that works, I may get more discount telco batteries and solar panels.
