Lowering Your Average Electricity Bill Per Month?
One of the best ways to lower your average electricity bill per month is to run all of your electronics through power strips that you can turn off at night. If the electronics are still plugged into the wall on their own, they will be using electricity all night long -- even if you have turned them off. Power strips have an on/off button that can cut off the charge, and they are not susceptible to this same problem. If a power strip is turned off, there is no current. Doing this can cut your electricity bill by a fifth.
