A: The average propane consumption per year for whole-house heating is estimated to be between 1200 and 1500 gallons per year for a 2,200 square foot home. However, the amount of propane a household uses varies depending on its specific uses in the household.
Household electricity use: 6,000 kWh per household per year for 3 residents average per household. So the household use per capita is 2,000 kWh or about of per capita electricity from all applications. Household Natural Gas use: 400 therms per household x 30 give 12,000 kWh equivalent electricity.Since much of the electricity is generated by natural gas, it is not totally unreasonable to compare these two in kilowatt hours.eduction of Total Household Energy Use. We are now down to about 8,000 kWh from gas and 1,800 kWh from electricity for a total of 9,800 kWh total of GHG producing household usage, down from the initial 18,000 kWh.
