1. To reduce your A/C costs during the warmer months, use fans and keep those doors, windows, and shades closed during the day to reduce heat coming in.

  2. Instead of overhead lights, use desktop lamps with CFL's.

  3. If possible, wash your clothes in cold water. About 90% of the energy used by washing machines goes to heating the water.

  4. Sealing cracks, gaps, leaks, and adding insulation can save up to 20% on home heating and cooling costs.

  5. Clean or replace all filters in your home once a month. Dirty filters make your system work harder and run longer than necessary.

  6. Use your microwave instead of your stove when cooking! The microwave uses two-thirds less energy than your stove.

  7. To ensure your appliances are running efficiently, defrost your refrigerator and freezer before ice buildup becomes 1/4-inch thick.

  8. Close blinds, shades, and drapes on the sunny side of your home during the day to help keep the house cooler bringing the temperature to a comfortable level.

  9. Don't peek in the oven while baking! Every time you peek, the temperature drops 25° F and requires additional energy to bring the temperature back up.

  10. Open curtains and shades during the day and let in the natural light instead of using lighting.

  11. Control your fixtures with a photocell or a timer to assure dusk-to-dawn only operation of your outdoor lights.

  12. Don't leave your computer on all day long. Only turn on your computer, monitor, printer, and fax machine when you need them.

  13. Set your thermostat as high as comfortably possible in the summer. The smaller the difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be.

  14. Using your ceiling fan will allow you to raise the thermostat setting about 4°F with no reduction in comfort.

  15. Set your thermostat to 78°F in the summer and 68°F in the winter. Every degree of extra heating or cooling will increase energy usage 6% to 8%.

  16. Refrigerators and freezers actually operate most efficiently when full, so keep your refrigerator and freezer as full as possible.

  17. Using dishwashers and clothes washers/dryers at night will keep the house cooler, reduce strain on the power grid during the peak usage hours of 4 PM and 6 PM, and reduce the chance of an emergency!

  18. Don't leave bathroom or kitchen ventilation fans running longer than necessary. They replace inside air with outside.

  19. If your home has single-pane windows, consider replacing them with more energy efficient windows, or adding solar shades or tinting film.

  20. Adjust the thermostat in small degree changes. Your home won't heat or cool faster by cranking it up.

  21. Install a programmable thermostat that will automatically adjust the temperature according to your schedule.

  22. Turn off the lights when they're not in use. Lighting accounts for about 15% of a typical residential utility bill.

  23. Don't leave your mobile phone plugged in overnight, it only takes a couple of hours to charge.

  24. Turn off the oven 10-15 minutes before cooking time runs out. Your food will continue to cook without using the extra electricity.

  25. Avoid placing appliances that give off heat such as lamps or TVs near a thermostat.
