Shaping Europe’s digital future

Green cloud and green data centres

The Commission is exploring measures to improve the energy efficiency and circular economy performance in cloud computing and data centres.

Digital technologies can offer green solutions to different sectors of the economy. Equally important is the ‘greening’ of the digital sector itself.

It has been estimated that digital technologies account for between 5 to 9% of global electricity consumption. This is likely to increase with digitisation and emerging technologies such as artificial intelligence, the Internet of Things and blockchain. This may lead to problematic increase of greenhouse gas emissions if no proper action is taken.

The European Commission conducted a study on Energy-efficient Cloud Computing Technologies and Policies for an Eco-friendly Cloud Market addressing the issue of growing energy consumption due to the expansion of cloud services in Europe.

Possible scenarios for the development of energy demand of data centers

The topic of energy-efficient cloud computing has become a priority for the EU. Data centres need to become more energy efficient, reuse waste energy such as heat, and use more renewable energy sources, with a view to becoming carbon-neutral by 2030.

To meet this goal, the Commission will rely on a mix of existing instruments, reviews of existing legislation and new initiatives.

Existing instruments include:

The Commission is also linking energy efficient data centres to policy and funding initiatives, notably through:

The Commission is currently conducting a study to address the lack of commonly accepted definitions and methods to assess the energy-efficiency, climate-neutrality and overall sustainability of data centres: 'Greening cloud computing and electronic communications services and networks: towards climate neutrality by 2050'.

Survey on synergies between data centres and energy systems

A new study about Data Centre and Energy Systems Synergies (DCESS) will analyse how local energy systems can use the waste heat and water generated from data centre operations. The contractors carrying out the study are now approaching stakeholders for feedback and other input.
