The Scottish Greens have confirmed they will force a vote at Holyrood on a moratorium on new data centre construction in Scotland. The move puts the Scottish Government in an uncomfortable position: caught between its green credentials and its economic ambitions at precisely the moment global investment in AI infrastructure is accelerating faster than at any point in computing history.
The case for a pause is not without merit. Data centres are energy-hungry. A large hyperscale facility can consume as much electricity as a small city, and Scotland's renewable grid, while impressive, is not unlimited. According to figures from National Grid ESO, data centre electricity demand across the UK is projected to more than double by 2030, with Scotland earmarked as a preferred location by several major operators precisely because of its cooler climate and cleaner power supply. The Greens' concern is real. The question is whether a moratorium is the right response to it.
Here is the counterargument, and it matters enormously for Scottish businesses and communities. Modern AI server farms do not simply consume energy, they produce vast quantities of waste heat as a by-product. That heat, currently vented into the atmosphere at facilities around the world, can warm homes, hospitals, schools, and greenhouses at near-zero marginal cost. Stockholm has been doing it for years. Copenhagen too. Helsinki's data centre waste heat now serves tens of thousands of residents through district heating networks. Scotland, with its cold climate, surplus renewable generation, and acres of available land, is arguably the most naturally suited location in Europe to build this circular economy of power, compute, and community heat. A moratorium does not pause that opportunity; it hands it to Ireland, Norway, or the Netherlands.
Scottish Enterprise has identified digital infrastructure as a priority sector for inward investment, and the Scottish Government's own National Strategy for Economic Transformation explicitly targets high-value, low-carbon industries. Research from the Fraser of Allander Institute has consistently flagged inward investment attraction as one of the key levers available to Scotland outside of full fiscal autonomy. Blocking data centre construction sends a signal to the global operators currently evaluating Scottish sites: go elsewhere. That signal, once sent, is difficult to retract.
The smarter legislative path is conditional approvals, not a blanket moratorium. Require waste-heat integration as a planning condition. Set energy efficiency thresholds. Mandate Power Usage Effectiveness ratings at or below industry best practice. These are tools that exist, that work, and that allow Scotland to attract the investment while capturing the community benefit. The Greens are right that unregulated data centre sprawl is a problem. But the answer to a planning and energy policy gap is better planning and energy policy, not a door slammed shut on one of the few industries that could simultaneously heat Scottish homes and fund the next generation of Scottish tech jobs.
For Edinburgh and the Central Belt, where most proposed Scottish data centre sites are concentrated, this vote matters directly. The capital already has a credible cluster of tech employers and a genuine pipeline of digital infrastructure projects. A moratorium does not protect that ecosystem, it freezes it. Scottish SMEs that depend on cloud infrastructure, AI tooling, and digital services built and hosted close to home have a stake in this outcome that goes well beyond abstract policy debate.
