Electrifying growth

Rapid growth in data center electricity consumption, but with big differences among EU members

For the European Union, data center electricity consumption is estimated at slightly below 100 TWh in 2022, almost 4% of total EU electricity demand, and is expected to reach almost 150 TWh by 2026.^[1] More interesting still, we are already seeing plenty of variation among EU members, as the right side of the chart shows. Ireland and Denmark already had a far larger share of data centers in national electricity usage then, say, Germany, and the gap with other members is expected to grow further.^[2]

Up until now, Northern European member countries have had the triple advantage of digitalization friendly policies, ample supplies of cheap renewable energy and a cold climate. The latter reduces the need for costly and energy-intensive cooling of data centers. With the growth in off-shore wind production, these advantages enabled innovative clusters to emerge. While demand for digital services is growing rapidly, rapid improvements in energy efficiency in data centers and data transmission networks have moderated the need for additional electricity capacity growth. More subtly, these countries – along with a few others, such as Sweden and Estonia – have put in place digital management systems to efficiently match electricity generation and consumption. To fulfil the potential of intermittent renewable energy sources requires real-time data at various points in the electric grid. And once agglomeration and innovation start in some particular place for whatever reason, positive feedback loops tend to emerge.

Can other members, especially in Southern Europe, catch up? Potentially yes, not least given the rapid fall in the costs of solar generation.^[3] Spain, in particular, has plenty of potential, not just due to having a lot of sun, but also plenty of relatively cheap space to build data centers in less populated areas.^[4] To unlock this potential, however, it will need to put in place not just physical but also technical, legal and commercial "infrastructure" – not an easy task in a politically polarized country. One way or the other, renewables are already reshaping Europe’s economic geography, beyond Europe’s old industrial belts. Investors better pay attention.
