It seems like your message got cut off. However, if you're discussing the average energy consumption of an American household, the figure "1.04 x 10^4" could refer to energy usage measured in kilowatt-hours (kWh), which equates to 10,400 kWh per year.
If that is indeed what you were referring to, this average can vary based on factors such as the size of the household, climate, and energy efficiency of appliances and systems in use.
If you have a more specific question or additional information to provide, please let me know!
