Global investment in data-centres is set to hit about $580 billion in 2025, surpassing the spend on new oil-supply development by roughly $40 billion, according to the IEA — and the question now is: how much of that growth will be powered by renewables? TechCrunch+1
Key takeaways
-
Massive spending push: The estimated $580 billion figure for data-centre investments in 2025 underlines the scale of infrastructure being deployed to support generative AI, cloud and edge computing workloads.
-
Renewables as default: The IEA expects that the majority of new data-centre power supply over the next decade will come from renewables, whether or not countries accelerate decarbonisation.
-
Solar favoured: Data-centre developers are increasingly favouring solar projects because of faster permitting, declining unit costs, and proximity to load, especially when co-located near large facilities.
-
Grid pressure & geography: Many new facilities are being built near cities or large population centres, placing strain on local grids, transmission corridors and water/cooling infrastructure.
Street view
The update signals a structural tail-wind for companies in the renewable-energy and data-centre infrastructure ecosystem. Investors may view the shift toward renewables as a mid-/long-term value driver — because as AI workloads scale, energy costs and sourcing become material to operating margins and ESG positioning. That said, execution risk remains — build-out timelines, grid permits, and local policy can introduce delays or cost surprises.
Catalysts / what’s next
-
Renewable sourcing deals: Look for announcements by major cloud/AI players securing long-term power-purchase agreements (PPAs) with solar/wind for upcoming data-centre expansions.
-
Data-centre siting & build-out: The timing and geography of where new data-centres are built will impact the renewable-penetration rates — regions with abundant solar/wind will lead.
-
Policy and regulatory updates: Data-centre operators increasingly need to align with environmental and grid-interconnection rules; regulatory tailwinds (e.g., tax credits for renewables) will matter.
-
Technology & efficiency gains: Innovations in cooling, power-conversion, workload scheduling (especially for AI) may reduce overall energy load and accelerate the renewable shift.
-
Financial disclosures & metrics: Watch for operators reporting “percentage of renewable supply” or “carbon intensity” of new facilities — investors will quantify how green their expansions are.
