My dad graduated high school in 1929, I learned a lot of tips from him, and have discovered many myself.

1.  Insulation is about dead air space.  Stacking newspapers is a good way to get rid of old papers and create a fire hazard. Throw them out and insulate your attic space to R39 up, R49 is better.  Insulate your crawl space. Always think "dead air". If you have windows, they are "cold" radiators.  Dad used to put a layer of sheet plastic outside to create a dead air space. I have double glazed windows ( had to replace anyway) and they help some, but  are not that efficient. What is efficient is a good interior window covering. I used honeycomb cell shades that cover the entire window opening ( and let in light) with three layers of honeycomb fabric cells. I have these on all my windows and the effect on my bill has been great.  I use small space heaters in rooms where I spend time, rather than heat the entire house. 

2.  Turn the lights off when you are not using them. I had that one beat into my head (LOL).

3. Don't run hot water needlessly and  use water restrictors.

4. Layer clothing.

5. Heat with gas if possible, electric heat is the LEAST  efficient of all methods.

6.  Get an economical car and don't leadfoot it. I got a speeding ticket a few months ago and now that I have been reminded, my gas mileage has improved 25%.

7. If you have a firelplace, don't heat with it. Waste of money. Get a EPA approved fireplace insert and it will pay back in two years. Mine burns three logs all night instead of three logs in two hours, and puts out so much heat I have to open a window sometimes. Don't burn wet wood.

8. I keep my bedroom cool, my dog and blankets keep me warm.

9. Go around your house and look for air leaks, under and around doors and windows, through floors ( insulation below will help a lot), and at all electrical outlets ( you can buy  foam gaskets to stop the constant stream of air from older switch and plug outlets.  You will be amazed at how much cold air comes into your house through them.  A trick is to pull the cover, and if you see dark dust on the areas covered by the plastic cover, that means a stream of air has been blowing through depositing dust.

10. Throw out your old fashioned incandescent light bulbs and get compact fluorescents. The 1-3 dollars a month you save means $20-$50 yearly, and they now make fluorescents that have nice color  that mimics daylight (SP35 or SPX35) and they no longer flicker.  

11.  Always think about how hot air escapes and cold air enters. Does your kitchen hood have a working damper?
