Tips and How-Tos
Focus first on the appliances you use most often, then improve the setting, schedule, airflow, loading, or maintenance that affects their work.
Make one useful change at a time
Start with a recent bill and identify what changed during the billing period: hotter weather, more people at home, longer operating hours, a new appliance, or equipment that needs attention. Pick one realistic adjustment and observe the next comparable period.
Protect comfort and safety
Energy saving should not compromise food storage, ventilation, electrical safety, medical needs, or the manufacturer's operating guidance. Switch off or unplug equipment only when it is safe and practical to do so.
