There are a few factors that have to be considered here.
What temperature someone is comfortable with.
Is the major portion of your home bathed in the sun or the shade.
Construction of the home.
Even the company who is supplying the power to your home.
But based on the figures that were given by a previous poster, there was only a difference from the highest figure to the lowest of $23 dollar.
Maybe it's me but a $23 amount is not going to keep me up at night.
