Computers and small servers sold in the EU are subject to ecodesign rules, as outlined in Regulation (EU) No 617/2013. They cap estimated annual energy consumption based on a product's average use pattern. They also include requirements for the efficiency of the internal power supply and power management.
Enterprise servers and data storage products are covered by Ecodesign Regulation (EU) 2019/424. Computer displays are also not covered, as they will be included in the revised regulation for electronic displays.
Switching to products that comply with ecodesign requirements will lead to electricity savings of up to 16.3 TWh by 2020, equivalent to cost savings for European citizens of up to EUR 2.6 billion.
