For residential homes, most energy consumption is (1) appliances and (2) convenience
The latter is to compare to commercial customers that consume energy as part of their production mix (labor, equipment, energy to run it all). Commercial convenience cooling (for employees), for instance, is only a portion of their consumption, depending on industry. A warehouse with electric fork lifts, for instance, consume a lot of energy overnight recharging.
So what convenience is there at home? Heating, cooling, lighting. Buy good equipment for these and adjust your behavior to use them more sparingly. Otherwise, what appliances are pushing up your overall load? Dishwasher, TV, clothes washer/dryer. Buy good equipment for these. Otherwise, what's left is "vampire" loads. Those things that just sit there using standby energy can add up, so being aware of your "base load" compared to others might be good to identify.
