Point-of-use energy monitors allow you to determine which of your appliances are efficient, and which of them aren’t. In addition, whole-house electric energy monitors can conveniently report instantaneous and daily kilowatt-hour consumption via a handy display. Both are excellent tools to help put electric use into perspective and will help you track your overall reduction efforts. However, you probably already have a meter provided by the electric company that can also give you useful information (many will display both instantaneous power and total energy)—you just need to read it.
