Certain doors (particularly older, metal-frame, hollow or thin ones) transmit a lot of warmth out of your home in the winter, and a lot of coolness in the summer. This can be prevented by replacing them with insulated doors.

Older ducts are typically both not insulated and leaky. As a result, large amounts of warmth and/or coolness that your heating and/or cooling systems have worked on escapes before it gets into your home. By replacing your ducts with modern performance systems this loss can be greatly reduced, and the air you have paid so much to have heated and/or cooled will then be retained for use.
Some heating systems do not make efficient use of the fuel they consume, while others use expensive fuels.
Some cooling systems do not make efficient use of the electricity they consume.
Some heaters do not make efficient use of the fuel they consume, while others use expensive fuels.
Some coolers do not make efficient use of the electricity they consume.
Raising the temperature settings of your cooling management controller will cause your cooling system to use less electricity, and is a worthwhile consideration in circumstances where there is little impact to comfort, or where clothing and other adjustments are preferable by the home's occupants.
Hydronic heating systems are among the most efficient in heat distribution.
Electric clothes dryers can be much more expensive to run than gas dryers. This is especially true of older and lower cost models, and the running cost difference is much more significant in homes with large numbers of people and laundry.
Running AC and/or Heat Pump systems using the stable temperature of geothermal sources (such as 20 ft underground) is preferable in certain situations (such as in locales with extreme weather shifts).
