Green Data Center Market to Reach USD 90.38 Billion by 2035 as AI Density Accelerates Liquid Cooling, Power Efficiency and Retrofit Spending

The global green data center market is projected to rise from USD 26.71 billion in 2025 to USD 90.38 billion by 2035, a 12.96% CAGR, as AI-related power and cooling needs drive investment. Direct-to-chip liquid cooling is forecast to grow from USD 2.41 billion to USD 17.33 billion, while retrofit spending is expected to increase from USD 5.21 billion to USD 18.41 billion over the same period. North America held 41.4% of the 2025 market; the article also notes grid and water constraints as drivers of efficiency upgrades.

Analysis

The investable mechanism is not the report’s headline CAGR; it is whether cooling and power equipment can be delivered and commissioned fast enough to convert constrained grid capacity into sellable compute. That favors integrated power/thermal vendors such as Eaton (ETN), Vertiv (VRT) and Schneider Electric (SU), while raising execution risk for buyers dependent on retrofits. Eaton’s Boyd Thermal deal broadens its offer, but integration and cross-selling—not market forecasts—must validate the thesis. Traditional HVAC firms may participate, but air-cooling exposure alone is less direct to the densest AI deployments.

The second-order effect is a rebound: better efficiency can lower facility overhead per unit of compute yet enable more total racks, so absolute electricity demand and grid bottlenecks may still rise. This supports power infrastructure and firm generation, but the Google–NextEra nuclear plan remains conditional on approvals and is not near-term capacity. Microsoft’s water claim concerns future sites, with deployment only expected from late 2027; it is not evidence of current fleet-wide savings.

Treat the market-size estimates as promotional third-party forecasts, not order guidance. Category overlap and retrofit timing could overstate addressable revenue. Immediate reaction may reward AI infrastructure names, but the 1–3 month test is order growth, backlog conversion and guidance; the 6–18 month test is delivered projects and proof that liquid-cooling adoption translates into margins and cash flow.

Key Decisions for Investors

• Prefer a staged, conditional long in ETN and VRT over buying the broad “green data center” theme: add only if subsequent results show data-center orders/backlog converting to revenue without deterioration in margins or cash conversion. Falsify on weaker orders, delayed delivery or negative guidance revisions.
• Track SU alongside ETN/VRT for integrated power-and-cooling exposure; do not infer near-term earnings from the report’s 2035 projections. Verify segment-level data-center sales and project lead times before sizing.
• Treat NEE as a longer-dated, event-driven watch rather than a near-term AI-power proxy: reassess only after regulatory milestones for the Duane Arnold restart and credible timing/capacity updates. Failure to secure approvals weakens the optionality.
• Monitor MSFT’s water-efficient design claims as a potential permitting and site-selection advantage from 2027 onward, but require operating-site evidence before assigning a material cost or valuation premium.
