Save money and the planet by using less and unplugging appliances when not in use. For heating and cooling energy saving tips visit: www.energysavers.gov/seasonal
If PG&E is your utility company, read this page and open the link to the PDF "So Now What" with information on energy use and the cost per appliance.
You can figure out your electrical expenses by the hour, day, week, month, even an entire year. Monitor the quality of your power by displaying Volts, amps, Watts , Watthours, VA , Line Frequency, and Power Factor.
