OnZero Signs Deal to Supply AI Waste Heat to Helsinki
OnZero Finland Oy, a subsidiary of Vienna-based OnZero Alpha Holdings GmbH, has signed a contract with Helsinki energy utility Helen Oy to feed recovered waste heat from AI computing into the city's district heating network. The planned 'AI Heat Factory' is expected to supply up to 525,000 MWh per year, covering the heating needs of about 70,000 apartments. OnZero's liquid-cooled architecture can recover up to 99 percent of waste heat and uses no evaporative water cooling on site. Helen has relied on data center waste heat since 2010 and plans to stop combustion-based energy generation by 2040. Helsinki would become OnZero's largest facility, after existing plants in Kemijärvi and Kerava have already delivered roughly 30,700 MWh of heat.
AI data center infrastructure with waste heat reuse is relevant to the broader tech industry, but this specific regional energy contract has limited direct impact on AdTech/MarTech.

Global Data Center Backlash Threatens AI Infrastructure Investments
Public opposition to data center construction is spreading from the U.S. to Europe and Asia, raising risks for investors. In Europe, over 70 projects were rejected or restricted in early 2026, with significant pushback in Scotland, Denmark, Spain, and the U.K. In South Korea, local residents are protesting data centers near homes, prompting proposed consent requirements and review systems. This backlash has delayed or canceled around $42 billion in European data center investments, compared to $77 billion in the U.S. Industry leaders acknowledge growing community scrutiny but see it as manageable, although costs may rise due to project delays. The AI boom continues, but communities now have significant power to derail large-scale plans.
AI slowdown not 'end of world' for data centers: Digital Realty CEO
Digital Realty CEO Andrew Power asserts that an AI development slowdown, pledged by major AI players Anthropic, OpenAI, and xAI, is not catastrophic for data center real estate. He argues that broader digital transformation and cloud computing growth remain strong demand drivers. The article notes that AI could account for 70% of global data center capacity demand by 2030, requiring nearly $7 trillion in capital outlay according to McKinsey. While stocks of data center REITs like Digital Realty and Equinix slumped, Power emphasizes that the company's funding model and $20 billion development pipeline position it well. JLL's Andrew Batson highlights that future data center growth lies in inference (adoption of AI tools), not just training new models, with only 1 in 4 Americans using AI daily.
Data Center Pushback Could Boost Dividend REITs
The article discusses how community and political backlash against AI data center construction could benefit existing data center REITs. Protests and potential legislation restricting new builds may limit supply, increasing the value of existing facilities. Analysts from Mizuho, Wells Fargo, and Green Street suggest that established REITs like Equinix and Digital Realty, with large land banks and development pipelines, are well-positioned. The article highlights three data center REITs: Digital Realty Trust, Equinix, and Iron Mountain, noting their strong year-to-date performance and dividend yields. PwC projects annual data center spending to rise to $1.8 trillion by 2050, while a recent NBC News poll shows 69% opposition to local data center construction. The piece concludes that while restrictions could slow growth, they also enhance the value of existing capacity.
