Start with a baseline
Run the free home energy audit with your square footage, state, and household size. You’ll get an estimated annual cost and a realistic savings range before you spend on equipment.
Habits that cost nothing
- Raise cooling setpoints and lower heating setpoints by 2–3°F when you’re away.
- Wash clothes in cold water and only run full dishwasher loads.
- Unplug or power-strip “vampire” devices in home offices and entertainment centers.
Upgrades worth pricing out
Attic insulation, smart thermostats, and heat pumps often qualify for utility or federal rebates — check your state program before you buy.
Thinking bigger: passive standard
If you are remodeling or building new, see our guide on what a passive house standard means for typical energy use, certification metrics, and realistic bill ranges versus a conventional home.
