About this data
- Energy intensity falls as energy is used more efficiently, and as the economy shifts from heavy industry towards services, which use less energy for each pound of output. Part of the UK's fall reflects goods that were once made in the UK being imported instead.
- Primary energy is the energy in fuels before they are converted or used: coal, oil and gas as they are extracted or imported, and the electricity generated by wind, solar, hydro and nuclear power. It excludes fuels used as raw materials, such as oil for making plastics.
