Energy Savings Guides
Guide Energy Audit Checklist Inspect your home for air leaks around windows/doors, check insulation levels in the attic, inspect HVAC equipment, and review lighting. Identifying these issues is the first step to major savings.
Guide Solar ROI Recap Installing solar panels can drastically reduce or eliminate electricity bills. While upfront costs are high, federal tax credits and state incentives can reduce the payback period to 5-9 years, with decades of free energy thereafter.
Guide LED Conversion Savings Calculator Replacing just 15 inefficient incandescent bulbs with LEDs can save you about $50 per year. LEDs use up to 90% less energy and last up to 25 times longer than traditional incandescent bulbs.
Frequently Asked Questions
What is a phantom load?
A phantom load, or standby power, is the energy consumed by electronics and appliances even when they are turned off but still plugged in. This can account for up to 10% of residential energy use.
How much can I save with a programmable thermostat?
By setting your thermostat back 7°-10°F for 8 hours a day from its normal setting, you can save as much as 10% a year on heating and cooling.
Are Energy Star appliances really worth the cost?
Yes. While they may have a higher upfront cost, Energy Star appliances use 10-50% less energy than standard models, which translates to significant savings on your utility bills over the life of the appliance.
Why should I lower my water heater temperature?
Water heating accounts for about 18% of the energy consumed in your home. Lowering the temperature from 140°F to 120°F not only saves energy but also slows mineral buildup and corrosion in your water heater and pipes.
What is the most cost-effective energy saving improvement?
Air sealing and adding insulation are typically the most cost-effective ways to improve energy efficiency and comfort, often yielding savings of 10-20% on heating and cooling bills.
