Why Investors Back Sustainable Data Centres

The AI boom is sparking a modern-day resource rush, with data centres emerging as the backbone of a digital gold mine. This surge mirrors historic investment frenzies where those who secure and refine the essential resources, in this case energy and infrastructure, define the next era of growth.

For investors, data centres represent a high-value frontier at the intersection of AI, energy efficiency, and innovation. However, success requires more than expansion, with those prioritising resilient, scalable, energy-smart solutions best positioned to strike gold in the long run.

Turning The Power Struggle Into An Opportunity For Data Centres

In the early 2000s, data centre placement relied primarily on access to high-speed optical connections and proximity to the community it served. Today, the defining constraint is energy availability, fuelled by the rise of AI, the use of more power-hungry chips, and the shift between cloud and edge computing.

According to Goldman Sachs, global data centre demand is predicted to increase 165% to 122 GW by 2030. Meanwhile, McKinsey is more bullish and projects global data centre capacity to rise by 300%, to 219 GW in 2030.

Evidently, there is a lot of uncertainty around data centre growth and the truth will lie somewhere in the middle. What is clear, however, is that data centres need a lot of power. In the US, the Department of Energy forecasts that data centres will account for 6.7% – 12% of total U.S. electricity usage by 2028, up from 4.4% in 2023. In Goldman Sachs’ estimates, this growth could more than double US data centre’s carbon dioxide emissions.

Recent news of DeepSeek compound the uncertainty around data centre growth and associated power demand. The Chinese start-up launched a model that required substantially less training and fewer chips than its competitors, while achieving similar performance.

It is unclear at this moment, whether DeepSeek’s breakthrough will moderate data centre demand or if the efficiency gains will be simply offset by higher demand growth – a phenomenon known as the “Jevons Paradox”.

But what is clear is that data centres are a modern-day gold rush, with annual capital spending on data centres estimated at around $300 billion. In the US, tech giants announced the Stargate project, which intends to invest $500 billion in AI infrastructure over the next four years.

In Europe, von der Leyen responded by announcing €50 billion for its European AI Champions Initiative at the Paris AI Summit. And, President Emmanuel Macro unveiled €109 billion in private AI investment in France.

With the growing power demands and the critical need for uninterrupted supply, innovative and clean energy solutions for data centres have become an urgent priority. Supporting emerging entrepreneurs and clean-tech start-ups in this space is essential to ensuring the long-term viability of today’s digital infrastructure.

Where To Stake Your Claim In Data Centres

As a matter of fact, emerging technologies are playing a crucial role to unlock sustainability in data centres, with some of the most promising solutions spanning energy storage, heat recovery systems, microgrids, alternative generation methods, and AI-driven energy optimisation.

Among these, supercapacitors stand out as one of the most transformative technologies for data centre energy management. Unlike traditional battery storage, they offer ultra-fast charging and discharging cycles to meet the need for uninterrupted power supply for AI-driven workloads. Through their optimized power delivery, fast response time, and ability to handle high loads, supercapacitors address the shortcomings of conventional batteries and can enhance computing power by up to 40%.

To supply data centres with renewable energy 24/7, back-up battery energy systems in combination with supercapacitors are still important, as they help to balance the fluctuations of renewable energy.

Alongside these, innovative technologies in heat recovery systems enable data centres to recycle and redistribute excess heat, either for internal efficiency improvements or for district heating applications.

Off-grid power solutions are also gaining traction to supply data centres. Ocean energy offers a renewable option for continuous base load generation and more and more data centres are entering direct Power Purchase Agreements with renewable energy generators. By handling large amounts of data, AI is poised to transform the energy system, from real-time verification of renewable energy use to the intelligent management of grids.

Striking Gold In Data Centres

For investors, the time to act is now. The convergence of AI growth, sustainability requirements, and energy constraints makes the data centre sector one of the most critical and promising areas for investment. With estimates suggesting there is up to $10 trillion of global economic value up for grabs, those who can provide innovative solutions stand to gain significantly.

As data centre demand continues to rise, we must ensure that the projects of tomorrow are built on a foundation of sustainability. The companies poised for success will be those that recognise the need for strategic innovation today.

The next five years will define data centres and the digital infrastructure landscape for decades to come, so its time investors start to seize the opportunity.
