We still get paper bills, which I won't get out and do the maths on.
All-Electric house with Solar water heating. Typically, bills run around $300 to almost $1000 through the Summer, running the A/C around 16-20hrs a day at 80°. It is an old system (30yrs), but the replacement would take at least 15 years to recoup the expenditure, and probably not even last that long (LOL).
Electricity comes in about 25c/kWh here at present, was 28c/kWh when we still had our "Carbon Tax."
(Which, while a highly political topic, didn't make companies think twice about pollution, they only jacked up their prices to compensate. The Government also spent at least 50% of the income on "welfare" payments to those who couldn't afford the additional cost of living).
Thankfully, the cheaper rates and rather mild Summer for us this year mean that the power bill shouldn't be as much of a shock. I'm estimating around $700-800 this time around.
Several appliances also contribute greatly to this usage:
~ 42" Panasonic Plasma TV (2007). These use around 400w/hr
~ Older F&P freezer (nearly 1000kWh yearly)
~ File/Web server (Pentium-4, "roomheater," 3 hard drives), uses around 100w/hr.
~ Assorted other computers, some lights (not really), Miele washer {always warm/hot washes)
