Miller says we waste about 43% of our energy unnecessarily. - Why worry about it? -Do you consider energy conservation and/or efficiency in your house? “ Tired of heating or cooling an empty house while you're away? In about an hour, you can be on your way to a more comfortable home. Depending on the model you select, you can program day and night temperatures and even a setting for every day of the week. You'll be more comfortable with your heating and cooling bill too.
