We just got our first bill for this place. Its for a period of 21 days & came to $96.20. This seemed excessive to me seems its only 21 days worth. So I called up to ask if it was an estimate or they took a proper reading (we have a dog).
She assured me it was a proper reading & went over the bill.
Went over what we use etc.

Normal/average size fridge
Normal average size (not a flat screen or plasma) TV, which is on all day most days (its off now though LOL)
And the PC which is on 24 hours. It goes into sleep mode but its never actually turned off properly.

We use the aircon sparingly.

Going off what I told her are our average day to day useage. its the computer chewing up the bill. I found that really interesting. DH has always told me that it costs the same to run the PC as it does to run a alarm clock. How wrong is he! She worked out that our average daily costs was about $3.50 a day. The PC would be about a $1.90 a day of that!

So I said so its not the air con, she said nope, looking at this bill if we use the aircon in the way I described ( a few hours in the evening at most & not everyday) then its defiantly the PC chewing it up. She worked out on average it would be accountable for about $170 of bill for a 90 day billing period! That is insane!

So people, if you are like us & just leave it on. Turn it off!
