The Surge in Big Tech's Clean Energy Demand Has Arrived

From the eastern shores of Scotland, the vast energy consumption of Big Tech can almost be seen. Located about 12 miles offshore is a wind farm, featuring 60 massive turbines, each with blades as long as a U.S. football field. The utility firms responsible for the Moray West project had initially claimed it would produce sufficient electricity to supply 1.3 million households upon its completion. However, this was before Amazon got involved.

In January, Amazon revealed that it had secured a deal for over half of the 880 megawatts produced by the site, as part of its continuous efforts to meet its ever-growing energy needs. As global corporations vie to establish the infrastructure required for artificial intelligence, wind farms in secluded Scottish locations are proving to be essential.

Last year, Europe witnessed an expenditure of $79.4 million on fresh data center initiatives, as reported by the research entity Global Data. The year 2024 is already showcasing a surge in demand. Microsoft today disclosed a substantial investment of $3.2 billion in data centers located in Sweden. Additionally, earlier this year, the tech giant revealed plans to expand its data center capacity in Germany and committed to investing $4.3 billion in AI infrastructure data centers in France. Amazon has unveiled a plan for a series of data centers in Brandenburg, Germany, as a part of an $8.5 billion investment in the country, and later announced an investment of $17.1 billion in Spain. Meanwhile, Google has committed $1.1 billion to expand its Finnish data center, aiming to bolster AI development.

As major technology corporations accelerate their efforts to construct additional data centers, there's an underlying sense of urgency about securing the necessary energy to power them. Companies like Microsoft, Meta, and Google have set ambitious goals to achieve net zero emissions before 2030, while Amazon, known for its extensive logistics network, aims for 2040. To reach these objectives, they have spent the last ten years aggressively acquiring renewable energy agreements from wind and solar power providers. However, these initiatives depend on electricity grids that are struggling to meet the rising demand for clean energy. This challenge is prompting these tech behemoths to rethink their energy-heavy future strategies, including the possibility of creating independent power networks, essentially bypassing traditional power grids.

Colm Shorten, the senior director of data center strategy at JLL, a real estate services firm, acknowledges the growing need for alternative energy sources as power requirements surge. He notes that data centers are progressively exploring direct access to energy, be it through gas or diesel generators, or cutting-edge solutions like green hydrogen.

Data centers rely on electricity for two main reasons. Firstly, it's needed to fuel the processors that facilitate the functioning of computer algorithms or video games. Secondly, it's essential for maintaining server temperatures to prevent them from overheating and malfunctioning. Efforts like employing liquid cooling methods for processors rather than air cooling are anticipated to achieve slight reductions in energy consumption. However, projections from the International Energy Association suggest that by 2026, the energy requirements of data centers could potentially double, largely due to the increasing needs of artificial intelligence technologies.

Over the last five years, technology firms have been aggressively acquiring renewable energy contracts, known as power purchase agreements (PPAs). These agreements allow operators of data centers to secure electricity from sources like wind or solar farms before these projects are even constructed. In Denmark, solar farms have been financed by Meta, while in Norway, wind farms have received funding from Google. Tech companies were among the first to engage in such agreements, playing a significant role in boosting the now flourishing PPA market in Europe, according to Christoph Zipf, a spokesperson for WindEurope. Recently, Microsoft finalized the largest renewable energy transaction ever, with a $10 billion agreement for clean energy spanning Europe and the United States.

However, even as renewable energy sources grow, the existing electrical grid is turning into a significant obstacle. This is particularly true in Europe, where an influx of renewable energy providers are attempting to integrate into the grid to meet the increasing demand for green energy across various industries. Meta's CEO, Mark Zuckerberg, voiced concerns about impending energy shortages during a podcast in April, stating, "We're going to face energy limitations." Similarly, at a gathering in Davos, OpenAI's CEO, Sam Altman, highlighted the challenge of supplying sufficient power to support the progression of artificial intelligence. He emphasized at a Bloomberg function, "Achieving our goals is impossible without some form of innovation."

Grid managers are essentially echoing a unified message. Eirgrid, Ireland's government-run power supplier, pointed to grid difficulties as the reason for enacting what amounted to a temporary halt on new data centers in Dublin two years ago. Following suit, when Amsterdam's local government implemented a comparable stoppage, the Dutch Data Center Association, a trade organization, responded critically. In a declaration, they mentioned, "The existing grid congestion in North Holland is hindering the expansion of the data center industry."

Data centers are increasingly locating in more noticeable areas of Europe, causing potential unrest among smaller communities that feel the impact of their presence. Simon Hinterholzer, a researcher at the Borderstep Institute for Innovation and Sustainability in Germany, has noted a shift in this trend, especially in Germany. "Previously, Frankfurt was the prime location for the construction of new data centers," he observed. "However, this trend has seen a dramatic shift in the past couple of years." He highlights the development of a 300-megawatt data center in the quaint town of Wustermark and points to Amazon's recent expansion into Brandenburg, a region next to Berlin, where over 70 wind turbines were erected last year.

As the demand for long-term solutions grows, there's an increasing push for data centers to become self-sufficient. Ricardo Abad, the founder of Quark, a data center, points out, "AI projects are expanding rapidly, now requiring up to 1 gigawatt of power—a demand that conventional power grids can't meet." Quark is in the process of developing a new facility in Spain with a partner, which will produce its own electricity using solar and wind energy on-site. While these initiatives are technically still connected to the power grid, allowing them to sell any surplus energy, they possess the capability to function autonomously, according to Abad.

In the same year that Dublin declared limitations on data center operations, Amazon inaugurated its biggest solar farm to date, covering the rooftop and parking area of its distribution center in Seville, Spain. Meanwhile, Google's European lead for data center site selection strategy has shown enthusiasm for incorporating renewable energy sources directly at its upcoming server locations. Both Microsoft and Meta have refuted involvement in projects that operate completely independently of the electrical grid. However, in Dublin, Microsoft is in the process of constructing a data center that will include its own reserve gas-powered facility, ensuring the center's operations can continue uninterrupted, even in the event of being disconnected from the main power grid.

Major technology companies are actively seeking innovative clean energy technologies, even those that are still in the conceptual or developmental phases. Kilian Wagner, a specialist in sustainable digital infrastructures with Bitkom, a German digital organization, emphasizes the importance of future technologies such as state-of-the-art nuclear reactors, renewable energy sources, and energy storage systems in achieving sustainability goals. Sam Altman of OpenAI has invested in Helion Energy, a U.S.-based nuclear fusion enterprise. This company has committed to supplying Microsoft with 50 megawatts of power from its inaugural fusion power plant once it's operational. In the United States, Microsoft has been exploring the use of hydrogen fuel cells as a zero-emission alternative for power backup, highlighting their potential benefits.

The implications of data centers disconnecting from the traditional power grid remain uncertain for the general populace. If major technology companies decide to independently pursue renewable energy, they might significantly advance in finding the next sustainable power solution. However, until such a breakthrough occurs, they are reliant on the existing electrical grid.
