Sharon - I think your hydro bill is probably accurate to the amount you are using. We all know hydro costs have had excessive increases. Especially in peak times. I have had bills @ $300 a month and now they are about $90 a month. I'm single and not a big hydro user if I pay attention. Not using my air conditioning. How many fridges do you have? Freezers? Air conditioning? Dehumidifier? Pool? Hot tub? Its hard to keep hydro costs down.
