Tips for an Energy Efficient Home

  • Proper insulation is critical to reducing the cost of heating. Check your insulation to ensure all gaps are caulked to prevent warm air from escaping. Does your attic need more insulation?  Using a programmable thermostat is another way to decrease energy use by reducing consumption in the evening and when absent from the home.
  • Calculate your energy usage through the website, ENERGY STAR Home Energy Yardstick. Learn about energy efficient products and other home energy tips at Energy Star. To reduce your energy bills, look for the ENERGY STAR label when purchasing appliances. 
  • Switch out traditional light bulbs for energy efficient bulbs. Check out this comparison completed by Earth Gauge (PDF) to see the amount of energy saved by making the switch.
  • A beautiful, relatively inexpensive way of reducing energy consumptions and emissions is through alternative landscaping. Planting the right tree in the right place can help save up to 20% on energy costs. Find out where to plant your next tree to maximize your benefits by visiting the interactive website Energy-Saving Trees. Reduce total lawn area to avoid extensive chemical use and maintenance.
