The IEA estimates that global data centre electricity consumption in 2022 was 240-340 TWh, or around 1-1.3% of global final electricity demand. This excludes energy used for cryptocurrency mining, which was estimated to be around 110 TWh in 2022.
To date, most policy efforts have focused on the energy used for cooling and lighting within data centres, as well as the use of renewable energy and export of waste heat. Developing policy to address ICT energy use is more difficult. There is a lack of suitable metrics, a lack of the data required for metrics, and the data centre environment is very complex and highly dynamic.
EDNA’s workstream on data centres addresses these issues, and more information will be posted here as the workstream develops over time.
EDNA’s Total Energy Model models the energy consumption of data centres – this work is continuously evolving.
