Considering all of the appliances that the average home uses--microwaves, light bulbs, dishwashers, refrigerators--is it safe to say that all of the electrical energy in a home will be converted to thermal energy inside the home?
If you think about the resistance going through wires, that is converted to heat. The photons from the light will eventually be converted to heat. The refrigerator makes excess heat. Is there anything that doesn't end up as thermal energy?
Answer
Ways I can think of to export energy from a home that do not heat the interior:
Light through windows
Radio energy from transmitters (WiFi, cell phone, radio, power supply noise)
Sound from stereo/TV
Charge in batteries
Hot items carried out (coffee in travel mug)
Pressure in car/bike tires supplied from your pump
Vented hot air from dryer, shower, oven, furnace, water heater
Hair heated by a dryer and still warm when you go outside
Many ways, but a very small proportion of the electrical energy entering
