Commercial energy use includes the consumption of the service sector. It is highly connected to population growth (as services tend to population serving). Commercial energy use is driven by electrical, heating, and cooling of buildings and other structures, though traffic lights, water, and sewer systems are also included in this category.[110]

The EIA expects commercial energy use to expand by an annual 1.5% globally. Energy use will grow more quickly in developing nations, as OECD states expect much slower population growth and faster adoption of energy efficiency measures.[111]
