Tackling the Data Centre Energy Crisis with Light-Based Microchips
Eindhoven, Thursday 2 April 2026
With Dutch data centre energy demand projected to double by 2030, a new Eindhoven consortium leverages light-based microchips to drastically cut consumption and meet national sustainability targets.
The Escalating Energy Demands of Artificial Intelligence
The Dutch digital infrastructure is currently grappling with unprecedented energy demands, heavily exacerbated by the rapid proliferation of artificial intelligence [GPT]. Data centres presently account for approximately 5% of the total electricity consumption in the Netherlands [1][3]. However, as machine learning workloads intensify—evidenced by technology giants such as Google reporting up to a 48% increase in greenhouse gas emissions since 2019—this figure is set to surge [1][3]. By 2030, the electricity demand from data centres in the Netherlands is projected to double, reaching 945 terawatt-hours [1][3]. This projection indicates that current baseline consumption levels for these facilities sit at approximately 472.5 terawatt-hours [1][3].
Integrated Photonics as a Strategic Solution
To circumvent the physical limitations of traditional electronics, a strategic consortium initiated the construction of the world’s first industrial photonic chip factory in Eindhoven in early March 2026 [1][3]. This collaborative effort unites the Netherlands Organisation for Applied Scientific Research (TNO), Eindhoven University of Technology, PhotonDelta, SMART Photonics, and the High Tech Campus Eindhoven [1][3]. Their objective is to pioneer the high-volume production of Photonic Integrated Circuits (PICs) [2]. Unlike conventional microchips, PICs utilise light rather than electricity to process data, allowing information to travel without electrical resistance [2]. This fundamental shift enables significantly higher bandwidths with minimal energy loss, making PIC-based optical transceivers highly advantageous for modern hyperscale data centres [2].
European Autonomy and Grid Integration
From a policy perspective, integrated photonics is officially recognised by both the European Union and the Dutch government as a strategic pillar for Europe’s future digital and industrial autonomy [2]. A government-commissioned report, ‘The Route to Future Prosperity’, explicitly highlighted the necessity of high-volume photonic chip production to combat sluggish economic growth and reduce technological dependency on foreign markets [2]. Beyond microchip innovation, structural efficiencies are also being evaluated to mitigate national grid congestion [1][3]. Stijn Grove, Managing Director of the Dutch Data Center Association, has advocated for sharing cloud servers to optimise resource use, noting that consolidating ten companies onto two shared servers can yield enormous energy savings by balancing day and night computational loads [1][3]. Furthermore, connecting these massive facilities directly to the high-voltage grid can relieve the medium-voltage grid, freeing up capacity for residential and commercial expansion [3].
