Energy in buildings

4.2 Energy-efficient lighting

In 2017, lighting in buildings in the domestic and services sectors accounted for about 10% of UK electricity use. The domestic sector used approximately 14 TWh and the services sector a further 21 TWh, of which over a third was used in retail premises. As shown earlier in Figure 39, the promotion of low energy lighting has produced a dramatic reductions in electricity use. It is estimated that domestic lighting electricity use fell by about a third between 2002 and 2017 (BEIS, 2018c). This is equivalent to closing a large 600 megawatt power station. There is still plenty of potential for further savings.
