Cooking, well water, clothes drying, central AC: My max has been $70 and that was due to having to constantly run a dehumidifier from recent basement flooding, it is normally under $60. CFLs only got put in last month. Of course it is just me and my wife so if you have children it will go up a little (but certainly not double-triple!). I don't live in a cheap electricity area either.
I'll give people that heat with it credit, but that's about it. Curious what mine is going to be come winter because I am planning on moving over to an electric heat pump.
I can only get in the $60 range during the winter. Honestly, it really depends the type of environment you live in. I've got extreme heat and humidity to contend with in the Spring, Summer and Fall. 100-110+ degree weather, and humid to boot. If I weren't to have air conditioning running, my house would be sweltering and humid. Not only would this be extremely uncomfortable, but it's not all that great for the longevity of the house. Open a window and all you're doing is letting hot air in. In the winter, however, the weather does get cold (down to around 40 degrees most years), but I would turn on the heat far less than I turn on the air during the summer. The house would get down to around 60 degrees without heat, so not that bad. Besides, I can use blankets in the cold. There's only so much I can take off in the heat.
Everything in my house is electric. I've taken to washing larger loads clothes in cold water, showering in colder water, drying on a rack what I can, and combining loads for the dryer. I do run an electric mower, but it doesn't use up too much power (and saves me costs in other ways). I run overhead fans when I'm at home so I can set the A/C to a higher degree. I unplug devices when not in use. Lights are always off in unused areas of my home.
Still, my electricity bill was $133 last month. Why? The A/C. It takes a lot of work for the A/C to keep the house at around 80 degrees, even with efficient windows and thermal curtains. This is drastically reduced from what it was last year, so the changes I made did make a difference. But it is very, very difficult for some people to get the type of kWh that gets bandied about these forums as an aspirational consumption of power.
Now, if I still lived in Hawaii, my kWh cost rate would be astronomical, but my bill would be lower. No A/C, no heating, a tap water temperature that is sufficient for bathing, etc.
