Combustion appliances burn fuel for heating, water heating or cooking. These fuels should be properly vented to the outside for safety reasons, and it is advisable for the associated systems to be serviced and tested at least annually.

Outdoor lighting is often used for security purposes, to illuminate the presence of unauthorized persons. To avoid the use of energy to light areas unnecessarily, it is likely advantageous to use motion detectors to turn on lights only when there is movement.
Some water heaters lose much of the heat they consume. This is especially true of older and lower cost models, and important in homes with large numbers of people.
Some washers do not make efficient use of electricity and hot water. This is especially true of older models.
Some dryers do not make efficient use of the energy they consume. This is especially true of older models, and in homes with large numbers of people and laundry.
As with many electrical devices, certain electronic air cleaner/filters consume unnecessary amounts of electricity; it is usually advantageous to purchase energy efficient electronic air cleaner/filters when a replacement is necessary.
Certain windows (particularly older, metal-frame, single pane 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 multipaned and insulated frame windows.
With too little wall insulation, a lot of warmth escapes your home through your exterior walls in the winter, and a lot of coolness escapes in the summer. This can be prevented by putting insulation in the hollow spaces in the exterior walls of your house.
Solar pool covers minimize water evaporation and significantly reduce heat loss, while capturing significant heat from sunshine. Pools with solar covers will both raise the temperature of the pool themselves (often by tens of degrees), and retain the energy of any pool heater in use (thereby saving on any associated heating costs).
Although some manufacturers set water heater thermostats at 140° F, most households usually only need them set at 120° F. Setting the thermostat at a lower temperature threshold can save substantial amounts of energy.
