Cut Your Cape Cod Energy Bill: 10 Moves That Work

Most of what drives high energy bills in a Cape house — air leaks, humidity, and appliances running longer than they should — can be attacked this week with a screwdriver and an afternoon. Here are ten proven ways to lower energy bills Cape Cod homeowners can handle without calling a contractor. Even us.

10 Moves to Lower Energy Bills on Cape Cod

1. Program a thermostat setback. Drop the temperature at night and when the house is empty — a schedule beats willpower. If you heat with a heat pump, keep setbacks small; they recover slowly.
2. Check your water heater. Set it to 120°F. Hotter wastes standby energy around the clock and raises scald risk.
3. Seal the obvious leaks. Add door sweeps, weatherstrip the attic hatch, and install foam gaskets behind outlet and switch plates on exterior walls.
4. Clean the dryer vent. Lint means longer cycles and a fire hazard. Confirm the outside flapper opens freely while the dryer runs.
5. Put bath fans on timers. Twenty minutes after a shower, then off. A fan left running all day exhausts air you already paid to heat or cool.
6. Dehumidify instead of over-cooling. Cape summer discomfort is often humidity, not heat. A dehumidifier set near 50 percent lets you raise the AC a few degrees and feel just as comfortable.
7. Finish the LED swap. Hunt the holdouts: exterior floods, basement fixtures, closets, the range hood. The longest-running bulbs matter most.
8. Kill phantom loads. TVs, consoles, and cable boxes draw power around the clock. One switched power strip per media center shuts them all off at once.
9. Work your window coverings. Close curtains at night in winter to slow heat loss through the glass; close them on the sunny side on summer afternoons.
10. Book a Mass Save assessment. The no-cost home energy assessment pinpoints your house's specific weak spots, and rebates and incentives change regularly — check the current offerings.

Pro Tip from the Field

On the next windy day, hold a lit incense stick near your attic hatch, recessed lights, and the basement sill where foundation meets framing. Where the smoke trail bends, air is moving. In most Cape homes the attic hatch is the single biggest hole — weatherstrip the lip and add latches that pull it down tight, because an insulated hatch that doesn't seal still leaks.
