Gigantic Tech’s appetite for energy is almost observable on the east coast of Scotland. About 20 km from the sea there is a wind farm where each of the 60 giant turbines has blades about the length of an American football field. The utility companies behind the Moray West project he promissed Once completed, the facility will be capable of generating enough electricity to power 1.3 million homes. This was before Amazon stepped in.
Amazon in January announced has struck a deal to take over half of its 880 megawatts of generating capacity, part of an ongoing effort to satisfy an insatiable thirst for energy. As the world’s biggest companies race to build the infrastructure necessary to enable AI, even Scotland’s remote wind farms are becoming indispensable.
According to research firm Global Data, $79.4 million was spent on up-to-date data center projects in Europe last year. Already in 2024, there are signs of accelerating demand. Microsoft announced a $3.2 billion deal today choose Swedish data centers. Earlier this year, the company also announced it would double its data center footprint in Germany, while committing to a $4.3 billion data center investment in artificial intelligence infrastructure in France. Amazon announced the creation of a network of data centers in Brandenburg as part of a $8.5 billion deal investment in Germany, later consecrating other $17.1 billion for Spain. Google said so spend $1.1 billion for a data center in Finland to support the development of artificial intelligence.
As tech giants rush to build more data centers, there is panic behind the scenes about how to power them. Microsoft, Meta AND Google all plan to reach net zero before 2030, due to the massive logistical burden Amazon has set itself a goal of 2040. In pursuit of this goal, over the last decade, these companies have obtained renewable energy contracts with wind or photovoltaic energy companies. However, all of these projects rely on power grids that are buckling under the increased demand for neat energy. This is forcing tech giants to think about their energy-hungry future and consider how they could operate their own off-grid energy empires.
“There is a recognition that as energy demand increases, the industry will need to find alternative energy sources,” says Colm Shorten, senior director of data center strategy at real estate services firm JLL, explaining that server farms are increasingly looking on-the-wire power sources, whether gas or diesel generators or more pioneering technology such as green hydrogen.
Data centers need power for two main purposes. The first is to power the chips that enable computers to run algorithms or power video games. The second is to frosty the servers to prevent them from overheating and shutting down. Initiatives such as using liquid to frosty chips instead of air are expected to result in modest energy savings. However, forecasts still predict that data center power demand will be as high as double by 2026Thanks in part to the demands of artificial intelligence, according to the International Energy Association.
For the last five years, technology companies have gone on a growing frenzy of purchasing renewable energy contracts, called power purchase agreements (PPAs), which allow data center operators to reserve power from a wind farm or solar installation before the projects are completed. built. There are photovoltaic farms in Denmark paid for by Meta. There are wind farms financed by Google in Norway. Technology companies that were early adopters of these types of agreements have helped fuel Europe’s now booming PPA market, says Christoph Zipf, a spokesman for WindEurope. This month, Microsoft took the biggest hit in the world agreement on renewable energysigning a $10 billion neat energy deal in Europe and the US.
However, renewable energy sources still need to flow through the electricity grid, which is becoming a bottleneck – especially in Europe, where an increasing number of renewable energy producers are trying to connect to meet the demand for the green transition in many sectors. “We will face energy constraints” – Mark Zuckerberg, CEO of Meta predicted on the podcast in April. This year in Davos, OpenAI CEO Sam Altman also warned that the status quo would not give AI the power it needs to thrive. “You can’t achieve this without a breakthrough,” he said at a Bloomberg event.
