Electricity accounts for nearly one-third of global TFEC in the
buildings sector. Electricity consumption per household is used
as an indicator to suggest trends in the efficiency of electricity use
at the global and regional levels; however, this does not isolate
the effect of improved efficiency from the effect of changes in
demand for electricity services.
Globally, electricity consumption per household did not change
significantly between 2000 and 2014 – improvements averaged
0.5% annually over this period. 32 ( p See Figure 44.) However,
trends varied by region. In North America, Europe and the
Pacific, electricity consumption per household rose between
2000 and 2010, followed by a decline by 2014, associated in
part with improved energy efficiency. 33 In the Commonwealth
of Independent States (CIS) and Latin America, electricity
consumption per household remained relatively unchanged over
the period. In contrast, Africa and Asia saw a gradual increase
in electricity consumption per household, and the Middle East
experienced almost 50% growth. 34
“Electricity intensity” is often used as an indicator of energy
efficiency in the service sector i . The trends in the service sectors of
Europe, the CIS, North America, Asia and the Pacific have shown
declining electricity intensity since 2010 (and earlier in some
regions). The Middle East stands apart, demonstrating a notable
increase in electricity intensity in the service sector between
2000 and 2010, although it has levelled off in subsequent years.
Africa’s electricity intensity in the service sector declined steadily,
over the 14-year period. However, as with energy intensity in
general, trends in this sector are likely to be the product of a
complex set of factors, such as structural changes in economies
and relative energy access, in addition to the availability and use
of more-efficient technology. 35 ( p See Figure 45.)
Appliances and equipment (e.g., computers, fans, motors, etc.)
saw a steady increase in final energy demand from 1990 to 2014
and are becoming large energy end-users. 36 The increase is
due largely to a rapid increase in the total number of electricityusing
products per household, especially televisions and other
information and communication technologies. 37
On average in OECD countries, clothes dryers, refrigerators and
freezers consumed about two-thirds as much energy in 2014
as in 1990. In North America, the efficiency of air conditioners,
refrigerators and freezers improved rapidly between 1980 and
2010 and has stagnated in subsequent years. 38 In the United
i The electricity intensity of the service sector is defined as the ratio of the electricity consumption of the sector over its value added, measured in constant
purchasing power parities.
