The United Kingdom Generates Less Electricity per Person Than in the 1970s

Electricity generation per person in the United Kingdom rose through the 20th century to a peak of about 6,700 kWh per person in 2003, then declined by roughly one-third to about 4,200 kWh in the most recent year - levels lower than those seen in the late 1960s. This reversal runs counter to the global pattern, where per‑person generation has increased by more than 50% this century. Part of the fall reflects changing trade in power: net electricity imports grew from around 1% of demand in 2010 to about 9% in 2025, but overall domestic consumption has nevertheless fallen.

The usual explanation - deindustrialization - is only part of the story. Industrial electricity use has fallen by about a quarter since 2005 (larger on a per‑person basis), but residential and commercial consumption have declined by similar amounts, so shifts between sectors do not fully explain the drop. Improvements in energy efficiency have played a major role, driven by measures such as the switch from incandescent to LED lighting and tighter appliance efficiency standards, reducing demand alongside structural economic change.
