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.
Traditional faucets use three times the amount of water that newer, aerating faucets use.
Traditional shower heads can use three times the amount of water that newer shower heads use.
In addition to the protection they provide, storm windows and doors provide a significant additional thermal barrier and halt air leaks.
Most electronic equipment draws small amounts of power, even when they are in the 'off' state. Unfortunately, when many devices are in such a state, for 24 hours for every day in the year, the amount of power consumed is actually very significant.
Crawlspaces are prone to moisture-related problems and are hard to inspect and maintain. Air seal, insulate, and install vapor barrier on crawlspace floor.
Some freezers lose much of the coolness they make and do not make efficient use of the electricity they consume. This is especially true of older models, and important in homes with large numbers of people.
Significant amounts of warmth in winter and coolness in summer escapes up the chimney. The damper prevents these losses when closed.
Keep direct sunlight from shining into rooms and you'll not only keep everyone cooler, you'll also lower your utility bill.
