Sustainable Infrastructure: Building Resilient, Low-Carbon Projects

'AI boom triggers 160% data centre power surge'

Artificial intelligence (AI) is rapidly transforming industries from healthcare to finance, but it comes with a massive energy footprint. Data centres, the backbone of AI, consume huge amounts of power, pushing companies like Meta, Google, and Microsoft to find sustainable solutions. The complexity and scale of AI models, particularly training large neural networks, require extraordinary computational power, resulting in substantial carbon emissions. For example, maintaining optimal cooling in data centres alone adds significant energy overhead. This demand is further driven by AI technologies like autonomous vehicles and predictive analytics, which require continuous data processing. The increased energy use means more burning of coal, oil, and natural gas, which leads to higher emissions. With renewable energy not scaling fast enough, fossil fuels are still the main power source for many data centres. This reliance is especially concerning given projections that power demand in data centres will increase by 160% by 2030, with AI’s energy needs growing rapidly. Recent headlines show the scale of the challenge: Meta’s landmark 20-year deal to source nuclear power for its Illinois data centres underlines just how critical nuclear energy has become in meeting AI’s soaring electricity demand. Meanwhile, Google’s agreements to power its data centres with small nuclear reactors and Microsoft’s plans to restart the Three Mile Island plant further highlight how these tech giants are betting big on nuclear to keep AI running without ramping up carbon emissions. AI boom threatens net zero goals Data centres, the backbone of AI-powered systems, are among the most energy-intensive facilities in the world. According to the EU Energy Efficiency Directive (EED), operators must now demonstrate continual energy improvements. This directive aligns with broader regulations like the European Climate Law, which enforces the EU’s target of climate neutrality by 2050. In the UK, schemes like ESOS Phase 3 place additional energy reporting and efficiency requirements on operators. In Europe, three of the largest economies - the UK, Germany, and France - are at the forefront of efforts to decarbonise their economies and transition to net zero. However, the data centres operating within these countries are facing significant challenges in meeting their decarbonisation and sustainability targets. Recent findings from a CFP Energy survey highlight that while the majority of data centres in these countries have a net-zero strategy in place, achieving their targets remains elusive. Net zero strategy adoption • UK: 94% have a net zero strategy, but 22% are not meeting their decarbonisation and sustainability targets.• Germany: 90% have a net zero strategy, but 30% are falling short of their targets.• France: 86% have a net zero strategy, with 14% not hitting their targets. These statistics underscore a critical reality: despite ambitious targets and high adoption rates of net zero strategies, achieving actual decarbonisation is proving to be a major hurdle. This trend is particularly concerning as AI demand is poised to increase significantly. If the cost equation remains imbalanced, we may soon face a situation where net zero targets are discarded in favour of meeting the demands of AI, as is already happening in various parts of the world. The growing reliance on carbon offsetting With the rapid increase in energy demand from AI, many large tech companies, including Microsoft, are turning to carbon credits and voluntary carbon projects as a means to mitigate their environmental impact. This has become crucial for companies that simply cannot reduce their energy consumption with current technologies. For instance, Microsoft recently entered into an agreement with Re-Green, committing to offset its emissions through carbon credit purchases and climate-positive projects. While these measures help compensate for carbon emissions, they highlight a gap in current energy solutions: the technology and power infrastructure are not yet capable of fully supporting the sustainable growth of AI. Mitigating the environmental footprint of AI and data centres CFP Energy, a UK-based provider of energy trading, risk management, and environmental services, says it advocates for: • Sustainable construction — Reducing environmental impact from the outset by using low-embodied-carbon materials in data centre design, which helps cut emissions during both construction and operation. • Advanced cooling systems — Improving energy efficiency through approaches like liquid cooling, which reduce electricity usage while maintaining optimal performance in increasingly power-intensive environments. • Voluntary carbon offsetting — Compensating for unavoidable emissions with verified carbon credits. However, recent disputes - such as the suspension of a Kenyan soil-carbon project involving Netflix and Meta - reveal serious concerns about transparency, community impact, and oversight. These events highlight the need for stronger governance and ethical standards across the voluntary carbon market. • Collaboration — Developing joint solutions with governments, utilities, and technology partners - including renewable energy agreements and efficient hardware - to drive systemic progress and ensure sustainable AI infrastructure at scale. A legislative push towards sustainability The policy environment is rapidly evolving, with regulations like the Digital Operations Resilience Act and the Corporate Sustainability Reporting Directive mandating transparency on emissions and energy efficiency. Operators who fail to adapt risk falling behind, both in compliance and customer retention. Businesses increasingly prioritise sustainability, and carbon-conscious customers are gravitating towards providers with robust strategies for renewable energy adoption and operational efficiency. George Brown, Sustainability Researcher for Data Centres at CFP, comments, “The climate emergency is a clear signal for change, and we need sustainable solutions now. “While AI is driving innovation and is critical to our digital future, it - and the data centres that support it - must align with the environmental imperatives of the 21st century. "Data centres need to operate in a way that supports, rather than undermines, our environmental goals. Despite widespread net zero strategies, many data centres are failing to meet their targets. “At CFP Energy, we believe collaboration is key. Tech companies, governments, and energy providers must work together. Sustainable construction, advanced cooling, and voluntary carbon offsetting are essential. "Carbon credits are a temporary solution, but long-term investments in renewables and efficiency must accelerate. "Regulations are pushing for greater transparency and efficiency, and businesses that don’t adapt risk penalties and losing eco-conscious customers. AI’s growth must align with sustainability, and CFP Energy is committed to leading the transition. "Every stakeholder - governments, businesses, and consumers - must work together to ensure a sustainable digital landscape. Each has a role to play in ensuring that our digital future is also a sustainable one.”

Xela Energy gains approval for Hursley solar project

Xela Energy (formerly Clean Energy Capital), a UK-based provider of private-wire renewable energy systems for data centres and industrial-scale power consumers, has received full planning permission for a 5MW solar farm that will supply renewable electricity directly to IBM’s Hursley campus near Winchester, England. The project is the first in the UK to connect a data centre to a dedicated solar installation via a private-wire arrangement. The solar farm will be built on agricultural land located close to the Hursley site and will provide traceable renewable energy directly to the IBM campus. By operating independently of the UK’s main electricity grid and without reliance on government subsidies, the project is intended to contribute to national decarbonisation targets, while also helping to reduce strain on grid infrastructure and improve overall energy security. Once operational, the facility is expected to generate nearly 5 million kWh of energy per year. Over its lifetime, this is estimated to reduce CO₂ emissions by 46,000 tonnes - equivalent to planting around 60,000 trees. In addition to powering IBM’s 27,000ft² data centre, which opened in 1977, the project includes landscaping features and dedicated areas to support Biodiversity Net Gain. Xela Energy, which has a growing pipeline of private-wire schemes, describes its approach as land-led rather than consultancy-led - focusing on securing sites near large energy consumers to provide fully funded, dedicated clean energy solutions. The company develops, builds, owns, and operates each installation directly, delivering "low-cost, traceable electricity" to its clients. “This project represents a major milestone in how large power users can decarbonise with certainty, speed, and integrity,” claims Alexander Goodall, founder and CEO of Xela Energy. “It’s a blueprint for how the UK can decarbonise its most energy-intensive industries at scale. If our energy is unsustainable, so is our existence. "That’s why Xela Energy exists: to make clean, cost-effective power available directly at the point of use without waiting for policy, grid reform, or subsidies. Projects like this show we don’t have to choose between economic growth and environmental responsibility, it’s possible to have both.” The Hursley installation is set to begin construction in the coming months. It comes at a time when data centre energy demand is increasing, driven by generative AI and other high-performance computing workloads.

Allegro argues case for sustainable energy storage

As data centre expansion accelerates to meet the demands of AI, cryptocurrencies, and cloud services, Australia-based developer Allegro Energy is arguing for the relevance and applicability of its long-duration energy storage (LDES) technology in "enabling scalable, sustainable energy solutions tailored to the unique needs of modern data centres." With data centres operating on consistent, high-load profiles, they are uniquely positioned to benefit from a clean power strategy that combines renewable generation with long-duration energy storage. Allegro Energy’s modular, scalable, and environmentally-friendly battery systems, according to the company, "present a solution that overcomes the prohibitive cost, scalability, and sustainability challenges associated with traditional lithium-ion or vanadium-based systems." • Modularity & scalability — Allegro’s LDES systems are designed to grow in parallel with a data centre’s needs, allowing incremental investment and deployment. • Renewable compatibility — The system pairs with solar and wind energy, aiming to help data centres navigate grid volatility and peak pricing while advancing towards net zero carbon targets. • Climate-friendly storage chemistry — The water-based electrolyte technology is not resource-constrained, hoping to offer a low-impact alternative that can be deployed at scale. “The exponential growth of generative AI, cloud computing, and digital services has made energy a critical chokepoint in data infrastructure,” says Thomas Nann, CEO of Allegro Energy. “We believe the future of high-performance computing does not need to come at the cost of the planet. With our technology, data centres can be powered entirely by renewables, supported by reliable, cost-effective long-duration storage.” Allegro Energy’s proprietary, locally manufactured micro-emulsion electrolyte technology eliminates the need for scarce or rare metals, reducing fire risk and allowing for extended storage durations at a lower cost.

Data centre district heating project delivered at QMUL

Schneider Electric, a player in energy management and automation, and its EcoXpert Partner, Advanced Power Technology (APT), have delivered a data centre modernisation project at the Queen Mary University of London (QMUL). Together, the companies have created a platform for heat recovery at the University’s data centre, enabling waste heat from the facility to be connected to a campus-wide district heating network, providing heating and hot water for the buildings and student accommodation nearby. The project both reduces the campus' scope one CO2 emissions - in line with Queen Mary’s sustainability goals - and has also allowed it to reduce the costs of its energy bills. Furthermore, the new energy-efficient data centre has provided the university with increased resiliency and processing power for its on-premises, large-scale research and intensive computing applications, helping it to provision for future expansion. Queen Mary University of London is ranked 94th in the world in the 2025-26 edition of the US News and World Report Best Global Universities rankings, and today has over 32,000 students from more than 170  nationalities and 5,700 staff - with nine Nobel Prize winners among its former staff and students. It says it is committed to conducting "world-leading research" and adheres to the principles of sustainable development across all areas of its operational and academic activities. Its vision is to create and oversee the evolution of a large-scale distributed computing infrastructure needed to maintain the UK’s position as a world leader in particle physics. As such, the university is a participant in the Grid for Particle Physics (GridPP) project, a collaborative effort among particle physicists, computer scientists, and engineers to analyse data generated by high-energy physics experiments, such as those conducted at the world-famous Large Hadron Collider (LHC) at CERN in Switzerland. The size, scale, and importance of this work means that the university must operate and maintain a highly-efficient, on-premises data centre - ensuring it meets the technical requirements of existing and future research developments, especially those requiring High Throughput Computing (HTC) applications. Prior to the modernisation project, Queen Mary’s data centre was experiencing reliability, scalability, and availability issues which required manual, on-site interventions to fix. It was also becoming outdated and its operations were, at times, impacted due to a build-up of heat in its server racks from its inefficient cooling systems. Future research computing may also have been hindered due to the data centre’s hosting limitations. The refresh was, therefore, vital to improve and stabilise day-to-day operations. In addition, its proximity to the campus’ district heating network presented an opportunity for a new solution be designed and implemented to bring the data centre in line with the university’s sustainability goals. Schneider Electric’s data centre, power, and cooling solutions were already installed across Queen Mary’s estate, so when it came to the plans to upgrade its operations, the university directly sought help from Schneider Electric’s partner ecosystem. Schneider Electric’s long-standing EcoXpert Partners, Advanced Power Technology (APT), an independent supplier of critical power and cooling systems, was selected to help Queen Mary meet its modernisation and sustainability goals. Key to the strategy was the integration of components including Schneider Electric’s EcoStruxure Row Data Centre system. It also incorporated APC NetShelter Racks, APC NetBotz environmental monitoring equipment, InRow cooling, and EcoStruxure Data Centre Expert software. The new configuration provided by APT, according to Schneider Electric, delivered a more energy-efficient cooling solution and enabled the heat recovery to support the university’s sustainability strategy – allowing Queen Mary to transfer waste heat and reuse it directly for heating and hot water across various buildings, including student accommodation, via a district heating system. Professor Jonathan Hays, Queen Mary University of London, comments, “The support we've had from APT and Schneider Electric has been unparalleled. Both companies came together to help us develop an exciting and innovative project which would enable us to provision for the future. The biggest impact is that we were able to deliver on what we promised while improving our sustainability. The new data centre is more reliable and efficient than ever and, through the heat recovery, we have significantly reduced our spending on heating and hot water while gaining enhanced reputational benefits from taking a lead on sustainability within our data centre operations.” “The project at Queen Mary demonstrates how digital infrastructure can be a catalyst for net zero, allowing today’s organisations to benefit from the power of advanced computing,” adds Mark Yeeles, Vice President, Secure Power division, Schneider Electric UK & Ireland. “By combining innovative engineering with sustainable data centre solutions, the university has developed an enhanced infrastructure platform that will meet its research computing requirements while supporting its sustainability strategy.” “Schneider Electric’s EcoStruxure Data Centre solutions were essential to help Queen Mary bring together its power, cooling, racks, and management systems, and support the deployment of its high-density IT equipment needed for its research,” claims John Andrew, Technical Sales Manager, APT. “This approach also created a platform to support its sustainability objectives via heat reuse, while enabling the University to act proactively and preventatively to intercept and remediate potential future issues.” For more from Schneider Electric, click here.

New energy agreement for nLighten’s UK data centres

nLighten, a provider of sustainable edge data centre services operating across the UK, Germany, France, and the Netherlands, has entered into a new renewable energy supply agreement with UK-based provider Conrad Energy, covering all of nLighten’s edge data centre locations across the UK. Unlike traditional supply contracts, the agreement enables nLighten to monitor its renewable energy consumption with granularity – down to the asset level and on an hourly basis. The partnership, which initially started in April 2024 with the delivery of renewable power, was enhanced in January 2025 with the introduction of detailed tracking and reporting capabilities. Previously, nLighten’s UK energy procurement was based on market-driven purchases supplemented by annual Guarantees of Origin. Conrad Energy has progressively onboarded all nLighten UK meters, consolidating what was previously a fragmented energy procurement approach. Each month, nLighten receives a breakdown of its renewable energy supply from Conrad Energy. This includes asset-level insights into the share of wind, solar, and biomass sources contributing to the energy mix. The data allows nLighten to track its renewable coverage over time and calculate avoided CO₂ emissions based on the actual generation profile. “This collaboration goes beyond what most energy suppliers currently offer in the UK,” claims Francesco Marasco, VP of Energy Operations & Sustainability at nLighten. “Not only can we align our procurement with real-time pricing, but we now also have full transparency over how – and where – our renewable energy is being generated. It’s another step towards building the most sustainable edge data centre platform in Europe.” This model builds on learnings from a similar agreement nLighten established in Spain with Shell. However, the Conrad Energy agreement takes transparency a step further by providing visibility down to individual generation assets, not just the source. “We’re proud to support nLighten’s efforts to lead the way in data centre sustainability,” says Tim Foster, Director of Energy for Business at Conrad Energy. “By combining flexible supply structures with granular data visibility, we’re helping digital infrastructure operators align more closely with today’s energy realities and decarbonisation goals.” For more from nLighten, click here.
