Lighting represents almost 20% of global electricity consumption. This consumption is similar to the amount of electricity generated by nuclear power. The latest IEA estimates show the total savings potential in residential and services lighting at more than 2.4 EJ per year by 2030.

About lighting

To achieve energy savings in lighting, the IEA recommends governments: 

- Phase-out inefficient lighting products as soon as technically feasible and economically viable
- Require and promote improved lighting systems design and management by ensuring that building codes promote the use of natural light and include MEPS for lighting systems
