1. Start With a Home Energy Audit
A professional home energy audit is the cornerstone of any effective energy-saving plan. A certified auditor will examine your home from attic to basement, testing for air leaks, inspecting insulation levels, and evaluating major systems. The audit results in a report identifying improvement opportunities that can make the biggest impact on your bills and comfort.
- Why get an audit? Spot high-impact fixes and avoid wasted money on unnecessary upgrades.
- Cost-saving tip: Many local utilities offer audits at a reduced rate or even free.
- Tax credit: The Inflation Reduction Act covers 30% of the audit cost, up to $150, making it more affordable to get started.
2. Seal Air Leaks and Improve Insulation
One of the most effective and affordable ways to save energy is by sealing gaps and boosting insulation. Drafts around windows, doors, attics, and foundations account for substantial heat loss in winter and cooling loss in summer. Properly installed insulation keeps conditioned air where it belongs, reducing demand on heating and cooling systems.
- Common air leak locations: attic hatch, window frames, baseboards, electrical outlets, recessed lighting, and exterior doors.
- Insulation upgrades: Consider blown-in cellulose or fiberglass in attics and walls, rigid foam around foundations, and high-R-value options for new construction or major retrofits.
- Weatherstripping and caulking are quick DIY fixes that pay back fast.
3. Upgrade Your Heating and Cooling Systems
Heating and cooling account for nearly half of typical residential energy use. Investing in efficient equipment can yield ongoing savings year after year.
- Replace old HVAC units: Look for ENERGY STAR-rated furnaces, heat pumps, air conditioners, and boilers meeting high efficiency standards.
- Programmable and smart thermostats: Automate temperature setbacks to prevent energy waste when you’re away or asleep.
- Efficient ductwork: Sealing and insulating ducts prevents conditioned air from escaping into unconditioned spaces.
- Tax credits: The Energy Efficiency Home Improvement Credit covers 30% of costs (up to $600 per item, with an annual limit of $1,200). Eligible upgrades include central air, high-efficiency water heaters, and heat pumps—some heat-pump systems qualify for a $2,000 yearly credit.
4. Switch to Efficient Lighting
Lighting can represent up to 15% of your electricity use. Swapping out old incandescent bulbs for LEDs or CFLs instantly reduces consumption, lasts longer, and improves light quality.
- LED bulbs: Use at least 75% less energy and last 25 times longer than traditional bulbs.
- Lighting controls: Add dimmers, timers, and motion sensors to ensure lights are only on when needed.

5. Harness the Power of Smart Home Technology
Smart home devices allow you to monitor and control energy use remotely, automate schedules, and receive instant feedback on consumption.
- Smart plugs and outlets: Cut power to unused devices automatically.
- Smart power strips: Eliminate ‘phantom’ loads from electronics that draw power even when off.
- Wi-Fi-enabled thermostats: Adjust heating/cooling from your phone and analyze usage trends for further optimization.
Some devices even integrate with utility demand-response programs, netting you financial incentives for participating.
6. Opt for ENERGY STAR Appliances
When appliances wear out, replacing them with modern, ENERGY STAR-certified models ensures you get top performance with significantly lower energy consumption.
- Top energy savers: Refrigerators, dishwashers, clothes washers/dryers, and freezers.
- Special features: Many new appliances offer load-sensing, eco-wash, and steam cycles that use less water and electricity.
- Look for the yellow EnergyGuide label to compare estimated operating costs across models.
7. Tackle Water Heating Efficiency
Water heating is another major home energy expense. Adopting efficient fixtures and appliances, as well as considering alternative water heating technologies, can drive significant reductions.
- Low-flow fixtures: Install WaterSense-labeled showerheads and faucets to cut hot water use.
- Water heater upgrades: Opt for high-efficiency tankless units, heat pump water heaters, or well-insulated conventional tanks.
- Solar water heating: Harness the sun’s power and cut hot water costs by up to 50%. Panels can be added to roof or ground, with systems sized for your household’s needs.
- Recirculation systems: Move hot water quickly to fixtures, reducing waste while you wait for showers to heat up (these systems cost under $400).
- Insulate pipes: Prevent heat loss in hot water lines running through unconditioned spaces.
8. Embrace Clean Energy: Solar and Beyond
Switching to solar panels or other renewable energy options can shrink utility bills and increase your home’s sustainability. System prices have dropped dramatically in recent years, while tax incentives remain strong.
- Rooftop solar: System size (and price) depends on your home’s energy use and sun exposure. Expect costs from $3,000 to $30,000 before incentives, with typical payback periods of 7–12 years.
- Storage batteries: Adding battery backups enables energy usage during outages or peak times for greater flexibility.
- Other renewables: Some homes may also utilize small wind turbines, geothermal heat pumps, or fuel cells.
- Tax credits: The Residential Clean Energy Credit covers 30% of the cost of qualified clean energy additions (solar, wind, geothermal, fuel cells, storage technologies).
9. Deep Energy Retrofits and Their Impact
For homeowners seeking dramatic results, deep energy retrofits go beyond single-system upgrades with comprehensive, whole-home approaches. These projects combine multiple strategies: high-level insulation, air sealing, triple-pane windows, advanced HVAC, water heaters, lighting, ENERGY STAR appliances, and often solar panels.
- Typical savings range from 31% to 74% in site energy use—often more, depending on measures taken.
- Average carbon emissions reduction is around 54%, with some homes achieving up to 80%.
- Final performance depends on choices like fuel switching (gas to electric), house size, and family habits.
- Weatherization alone may save 10–15%, but deep retrofits can cut usage by 70% or more.
Example projects:
- Passive-house level upgrades: thick insulation, advanced windows, heat pump/solar hot water, and solar PV led to 75% less energy use.
