Lighting accounts for about 20% of global building electricity consumption (approximately 7 EJ in 2013). The latest IEA scenarios show the total electricity savings potential in building lighting by 2030 could be equivalent to all the electricity consumed in Africa in 2013. (Sources: ETP 2015, WEO 2015 and IEA World Energy Statistics and Balances 2014)
To achieve energy savings in lighting, the IEA recommends that 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 encourage the use of natural light and include minimum energy performance standards (MEPS) for lighting systems.
