TU Wien Study: AI Data Centers Must Become Flexible Power Users
An international research team led by TU Wien has published a study in the journal Joule warning that the rapid expansion of AI data centers could lead to a resurgence of fossil fuel power plants unless data centers become flexible electricity consumers. The study recommends shifting AI training to times of abundant renewable energy, new contracts with guaranteed base power and curtailable additional power (at most 35 hours per year), and better data on data center power consumption. The team highlights that 39% of planned US gas power capacity by end of 2025 is meant for data centers, citing xAI's use of mobile gas turbines in Mississippi without proper permits. They propose binding agreements to protect local populations from grid expansion costs. This contrasts with Nvidia CEO Jensen Huang's statements that fossil fuels will be used more in the coming years. The article also mentions Meta's new Enterprise Platform, which sells AI models, agents, and compute, to diversify beyond advertising.
The study highlights a critical challenge for AI infrastructure: the risk of fossil fuel resurgence due to data center power demand. This directly impacts the tech infrastructure layer relevant to AdTech, as AI processing needs grow. The findings could influence how data centers are powered and located, affecting cloud costs and sustainability for ad tech platforms.

Electricity Is Becoming AI's Main Bottleneck
This Substack deep dive argues that in 2026 the AI industry's primary constraint is shifting from chips to power. Citing the IEA’s April 2026 report, the author notes global data-centre electricity demand grew 17% in 2025 and demand from AI-focused facilities grew 50%. The IEA projects data-centre consumption will rise from 485 TWh in 2025 to about 950 TWh by 2030. The piece outlines why capital alone cannot deliver the required gigawatts, how power pricing and contracts (including behind-the-meter deals) affect project economics, and the implications for turbine makers, power producers, site selection, and investors over the next three years.
AI Labs Adopt Onsite Gas Power to Bypass Grid
SemiAnalysis examines how AI datacenter operators are increasingly deploying onsite gas generation to avoid multiyear grid interconnection delays. The report traces a rapid move from grid dependence to Bring Your Own Generation (BYOG) strategies—led by xAI’s truck‑mounted turbines—to enable faster time‑to‑power. It documents large orders (e.g., an OpenAI/Oracle 2.3 GW Texas plant), broad supplier participation (GE Vernova, Siemens Energy, Doosan Enerbility, Wärtsilä, Boom Supersonic, Bloom Energy, Caterpillar, and others), and three main generator families (aeroderivative/industrial gas turbines, reciprocating engines, and solid‑oxide fuel cells). The analysis covers tradeoffs—capex, lead times, ramp rates, redundancy/overbuild needs, permitting, supply‑chain bottlenecks (turbine blades/cores)—and emerging commercial models such as bridge power and Energy‑as‑a‑Service. The market is characterized by acute supplier booking, rising lead times, and material impacts on datacenter economics and deployment timelines.
AI Data Centers' Water Use Could Drop with Renewables
The rapid expansion of AI capabilities is intensifying competition for local water resources near data centers, as traditional air cooling is insufficient for high-performance AI processors, driving up direct water demand. The International Energy Agency estimates global data center water consumption at around 560 billion liters annually, with projections from Cornell University suggesting US data centers alone could exceed one trillion liters per year by 2030. A shift from coal and gas power to solar and wind could reduce AI infrastructure water footprint by up to 86%, as these renewables require no cooling water for operation. Hardware innovations, such as Nvidia's processors that function at higher temperatures, and closed-loop or immersion cooling systems reduce evaporative losses. Software optimizations and strategic location choices also help mitigate water impact. However, experts warn of a rebound effect: improved efficiency may lead to broader usage and offset absolute resource savings, necessitating accompanying software concepts and regulatory measures.
