Power Shortages Threaten U.S. AI Advancements
The future of artificial intelligence (AI) in the United States is increasingly uncertain, as looming domestic power shortages could impede progress in this crucial sector. Analysts at Goldman Sachs highlight the emerging reality that a reliable and robust power supply will likely prove to be as essential as advanced technology in the AI race.
In a report, Goldman Sachs analyst Hongcen Wei emphasizes that while many focus on the competition for chips from companies like NVIDIA Corp. and Advanced Micro Devices Inc., the availability of electrical power may ultimately become a decisive factor in who leads this technology frontier.
Current Landscape of U.S. AI Infrastructure
The United States currently leads the world in AI infrastructure, holding approximately 44% of global data center capacity, equivalent to over 50 gigawatts (GW). This capability surpasses the combined capacities of several advanced nations, including China and members of the European Union.
As of now, data centers account for 6% of total U.S. electricity consumption, with projections estimating this could escalate to 11% by 2030. However, this increasing demand coincides with a time when the energy grid is already under significant strain.
Challenges Facing U.S. Power Supply
The effective spare power capacity within the U.S. has decreased notably, dropping from 26% five years ago to a precarious 19% today—approaching the critical threshold of 15% that indicates tight energy supply. This reduction poses a severe risk for future developments, particularly as eight out of thirteen regional power markets have reached or dipped below these levels.
Goldman Sachs estimates that even under conservative growth projections, spare capacity across most regions will likely fall below 15% by 2030, creating significant constraints for future data center projects. In fact, if the growth of AI infrastructure accelerates—as certain analysts predict—the situation could become even more dire.
China's Strategic Advantage
In stark contrast to the challenges faced by the U.S., China is preparing to meet its AI demands head-on. The country, which is home to the world's second-largest data center network, boasts a considerable spare power capacity and is actively planning to expand its energy supply through a mix of renewable sources, coal, natural gas, and nuclear energy.
By 2030, projections indicate that China could possess effective spare capacity equating to around 400 GW—far exceeding the anticipated global demand for data center power, estimated at about 120 GW. This massive scale of development will provide China with a strategic advantage to facilitate rapid expansion in the data center space, supporting its growing AI industry.
Why the U.S. is Struggling
Goldman Sachs attributes the tightening of the U.S. energy grid to three main factors: surging demand from data centers, insufficient resources to replace retiring coal power with renewables and natural gas, and limited advancements in energy storage technologies.
Additional barriers include lengthy lead times and regulatory delays concerning the deployment of new gas turbines. Given these factors, Goldman does not expect to see significant increases in nuclear or gas capacity before 2030, due to construction and supply chain hurdles inhibiting progress.
The Need for Robust Energy Policies
While there are policy options available to support the growth of renewables or postpone the retirement of coal plants, Goldman Sachs remains skeptical that these measures will promptly rectify the existing trends in energy supply. The ongoing AI race is becoming increasingly about securing ample energy resources rather than merely acquiring superior technology.
Goldman succinctly notes, "A crucial ingredient to win the global AI race is ensuring a reliable and ample power supply to fuel data centers." Currently, as states grapple with tightening energy resources, it seems that China is positioning itself to emerge as a leader, while the U.S. may find itself at a disadvantage without significant changes to its energy strategy.
