Single Family Home Energy Consumption
Globally, energy consumed by single-family households was 3,550 Terawatt hour (tWh) as compared to the total energy consumed by all industry at 20,917 tWh. Single-family household energy consumed in the United States annually was 1,176 tWh, 1,096 tWh in Europe, and 355.61 tWh in China.
The above figures were presented in tWh unit instead of TBD unit as there was no available conversion factor found for TBD units. When looking for ways to express the answer in TBD units, we looked at various online converters, as well as articles and reports about measuring energy consumption. While there were no precompiled statistics pertaining to the requested information, we have estimated the figures using available statistics from various reports, database, and news articles. Below you will find detailed calculations, estimations, methodologies, and assumptions made to derive the figures.
UNITED STATES' SINGLE-FAMILY HOUSEHOLD ENERGY CONSUMPTION
According to EIA, the average annual energy consumption for a U.S. residential household was 10,766 kilowatt-hours (kWh) in 2016. The US consumption was more than 3 times higher than the global average of 3,353 kWh. In 2017, the total housing units in the US totaled 136.57 million and a report from the Federal Reserve Bank revealed that since the year 1990 up to present, single-family units accounted for 80% of the total housing units.
This means that the US single-family energy consumption was estimated to be 1,176tWh in 2017.

1 Kilowatt hour [kWh] = 0.000 000 001 Terawatt hours [TWh]
EUROPE'S SINGLE-FAMILY HOUSEHOLD ENERGY CONSUMPTION
In Europe, "the households or residential sector represented 25.4% of final energy consumption or 17.4% of gross inland energy consumption" as of 2016. According to EuroStat database, gross inland consumption of energy in Europe was measured 1,627 million tonnes of oil equivalent (Mtoe). Europe's housing status was classified into three — detached (single-family), semi-detached and flats. Detached households consisted of 33.3%, while families living in flats represents 42% of the population.
Total household energy consumption in Europe
Europe's single-house home energy consumption
= 283.10 Mtoe * 33.3%
= 94.27 Mtoe [1,096 tWh]
1 Mtoe = 11630000000 kWh
CHINA'S SINGLE-FAMILY HOUSEHOLD ENERGY CONSUMPTION
According to the ACEEE 2016 survey for Chinese households, "there is a notable gap in residential electricity consumption between urban and rural areas. The electricity consumption of urban households is about 1.4 times that of rural households, with the absolute value of 1,888 kWh/household/year and 1,371 kWh/household/year, respectively." The average residential electricity consumption between urban and rural areas was 1,630 kWh/household/year. A separate statistics reported that almost half (50%) of the total population in China lives in a high-rise residential building. In here, we assumed that the remaining 50% accounts for single-family households.
As of 2016, the average number of people living in one household in China was 3.11. If the latest total population in the country was at 1.357 billion, then the estimated number of household is:
Number of Chinese households
Estimated single-family household
= 436,334,405 * 50% = 218,167,203
China's single-family energy consumption
= 218,167,203 * 1,630 kWh
= 355.61 billion kWh [355.61 tWh]
GLOBAL SINGLE-FAMILY HOUSEHOLD ENERGY CONSUMPTION
According to the latest data available from Enerdata, the average kWh per household globally was 3,353. From UN report released in 2017, world's average number of people per household from 202 countries was 3.91. Current world population is measured at 7.6 billion.
Estimated total household worldwide
World's total household energy consumption
= 1.94 billion * 3,353 kWh = 6.52 trillion kWh
While there are no available statistics for % of single-family worldwide, and in order to estimate global single-family household energy consumption, we took the average percentage share of the 3 regions (US = 80%, China = 50%, and Europe = 33.3%). The average % of these 3 regions is 54.43%.
World's single-family home energy consumption
= 6.52 trillion kWh * 54.43%
= 3.55 trillion kWh [3,550 tWh]
Among the three regions, the United States has the highest energy consumption in the single-family household segment with consumption recorded at 1,176 tWh. Globally, energy consumed by single-family households was estimated to be 3,550 tWh. Europe's households account for more than 17% of the total gross inland energy consumption in the EU region. The Chinese single-family household's average energy consumption is 1,630 kWh/household per year.
