Set your water heater's maximum temperature to 120°F

You can reduce your water heating costs by simply lowering the thermostat setting on your water heater. For each 10°F reduction in water temperature, you can save between 3–5% in energy costs. The recommended temperature for optimal savings is 120°F. Reducing your water temperature also slows mineral buildup and corrosion in your water heater and pipes; this helps your water heater last longer and operate at maximum efficiency.

Safety Concerns: Water heaters set at 140°F pose risks of scalding and burns, especially for children. Lowering the temperature can, however, create more risk for Legionnaires Disease. Search online for details if this is a concern.

Attend a Powerware Party

At these small group gatherings, you will become more “power-aware” through activities, demonstrations of energy saving devices, and discussions about how to save energy and money at home. Contact us at greenhomes@frederickcountymd.gov for more information. 

Read your power meter monthly and submit kWh (kilowatt-hour) usage to your utility

You’ve probably noticed that your electric meter is not read every month; for those months between meter readings, an estimate is calculated. Not having actual monthly readings will make it hard to determine whether or not you are saving energy compared to the previous month or year. You will have a more accurate picture for tracking your energy usage and savings when you have actual, not estimated, data.

You can read your own meter each month and use the phone (call 1.800.255.3443 and say “meter reading”) or visit the Potomac Edison website to submit your information. Instructions for reading and reporting your electricity usage appear on your monthly billing statement.

Try out an online home energy analyzer

Try one of these tools to help you estimate how your household uses energy:

Potomac Edison’s Home Energy Center Online Analyzer: This web-based self-service option presents you with home efficiency and conservation recommendations for managing your energy costs. Upon completion, you have the option of receiving a reward of four CFLs!

The Energy Guide: provides a Fast Track and an In Depth Analysis of your energy use, providing you with pinpointed recommendations on what to do to begin saving energy now. You can also calculate how much money you can save by replacing appliances.

ENERGY STAR® Yardstick: If you have five minutes and your last 12 months of utility bills, use the ENERGY STAR® Home Energy Yardstick to compare your home’s energy efficiency to similar homes across the country and get recommendations for energy-saving home improvements from ENERGY STAR®. You will also need to enter some basic information about your home (such as zip code, age, square footage, and number of occupants). If you don’t have your bills, contact your utility for a 12-month summary.

Track your household’s electricity usage

Tracking your monthly energy consumption of kWh used and the dollar amount spent can help you have a better understanding of how you use energy and show your savings, as you work to make your home more energy efficient. A simple spreadsheet may be all you need to track your electricity usage patterns and costs.

Better yet, use the online tool, WattzOn, to enter your utility data, plot usage, and calculate savings from one year to the next. The Green Homes Challenge has its own WattzOn Group that you can join. Have the square footage of your home and utility bill statements or data ready when you register. The WattzOn tool aggregates savings for the Green Homes Challenge group members; this helps us evaluate the effectiveness of the Power Saver Challenge. We encourage you to try it!
