I don't even know how much my bill is total cause my wife pays the bills. I will check next month. But what I wanted to add, is that my entire house is electric. I don't have anything on gas. I use a computer tower plus two laptops, Flat screen tv, electric stove, microwave, toaster, dryer and standar bulbs around the house. And now I will add an electric heater. I guess one would say I'm pushing it. But really all I'm adding to what is normal for me is the 400w light.

When people mention microwave wattage, one has to keep in mind the amount of time a microwave is in use. Being on display does not count. So you can't compare a mic with a light that you may leave on for 18hours a day.
