Of all the electrical energy used in a home, is there any portion that won't eventually become thermal energy in the home? 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?
 A: My electric heat-pump removes more sensible heat from my house than it adds into it - and the electric bill comes to the house. So perhaps the answer should be no.
The point is the temperature of my house, may not be proportional to how much electricity we use that day. 
A: 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
A: How about this also: you use electricity at home for heating, cooking etc to maintain the life of people and pets in the house. Then they go outside and perform mechanical work on something, e.g., at the gym.
For example, consider the reaction of ethanol burning (without worrying about details) 
$C_2H_5OH + O_2 = CO_2 + H_2O$ + energy
Now imagine somebody cooking moonshine alcohol at home, combining [electrical] energy, water, and carbon dioxide. In principle this should be possible, the reaction is reversible. Next this individual consumes the product and goes outside to work out, or do some other great things involving some mechanical work. This would be the case of using electricity at home that does not end up as heat at home.
More seriously, we could consider other chemical reactions that can be carried out at home using electrical energy, that would produce some "fuel" for a human being (or his pet, his car, his toy helicopter etc) that would be able to use it for doing mechanical work outside of the house.
