How Much Energy Do Appliances
Use?
Some household
appliances have a bigger appetite for energy than others, and it's helpful to
identify the major culprits. By monitoring what appliances are on at any given
time and keeping an eye on your electric meter, you can track changes in your
household's energy usage. More information on how to read your electric
meter.
