BCG: How to Feed AI's Energy Appetite Sustainably

The explosive growth of Generative AI (GenAI) is not only transforming industries but also significantly influencing global energy consumption.

This rapid development brings a critical challenge in the increasing demand for energy, which could potentially conflict with the global climate change objectives.

A detailed from Boston Consulting Group (BCG) delves into the intersection of GenAI growth and the energy transition, highlighting the need for careful navigation by business leaders to balance these trends.

AI's energy appetite

Within the United States, GenAI development has led to an alarming spike in energy use, particularly evident in data centres where electricity demand is forecasted to increase by 15% to 20% annually.

By 2030, this could account for a staggering 100 to 130 gigawatt hours, enough to power two-thirds of all US households.

Such rapid growth puts a considerable strain on existing power structures, bringing concerns over potential shortages in reliable energy supplies.

Data centres, the homes of AI, are expected to account for more than 60% of this additional power demand.

This unveils a critical bottleneck: while AI advances at breakneck speed, the energy infrastructure lags, struggling to match the pace.

For instance, constructing new transmission lines can take over a decade, far slower than the rapid scaling needed by AI heavyweights.

Innovative responses to AI's energy consumption

Forward-thinking AI corporations are investing in research and development of smaller, less energy-intensive models that do not compromise on performance.

At the same time, they are enhancing data centre designs to improve efficiency and reduce energy wastage.

Yet, their initiative extends beyond just refining their architectural blueprints; many are partaking in alliances with energy firms, working towards smarter grid management and holistic solutions that amplify overall energetic efficiency.

Such collaborations are beneficial for both sectors – energy companies find a way to scale up capabilities to meet the burgeoning demand while AI firms ensure the sustainability of their rapid growth.

Energy suppliers themselves are also compelled to innovate, needing to deploy capital swiftly to keep up with the AI sector's explosive growth.

This urgency, however, opens doors for potentially transformative long-term contracts and cooperative technology ventures that could redefine the industry landscape.

Pursuing sustainable energy alternatives

The tech world is showing increasing interest in nuclear power as a green energy source for AI operations, viewing it as a potentially stable and scalable solution.

A notable example is Microsoft's 20-year deal with Constellation Energy to reboot operations at the Three Mile Island nuclear plant, an initiative valued at US$1.6bn.

Simultaneously, tech giants like Google and Amazon are investing in small modular reactors (SMRs), which provide a scalable, cleaner energy alternative.

This burgeoning interest in nuclear technology could position AI companies not just as energy consumers but as pivotal players in energy innovation, or even as energy producers.

By pioneering advancements in renewable sources and nuclear solutions, these firms can actively contribute to environmental sustainability.

“We can’t ignore the risks around nuclear, but it gives us a line of sight to a scalable solution to deliver more baseload power - and green power at that,” says Maurice Berns, Chair of BCG's Centre for Energy Impact.

A shared vision for sustainable innovation

The report from BCG proposes a future energy framework that is autonomous, decentralised and promotes minimal waste.

Ironically, the very AI technologies contributing to today’s heightened energy demands could be key to powering sustainable systems of tomorrow. However, reaching this equilibrium demands strategic initiatives.

BCG urges companies to optimise current electricity usage to alleviate impending shortages while investing in long-term, sustainable energy solutions.

Critical to this are partnerships between the energy and AI industries, fostering a collaborative spirit essential for tackling these challenges and propelling technological and ecological advancements together.

By setting their sights on shared goals, both sectors can forge a path towards a future that’s both technologically advanced and environmentally responsible.
