US Electricity Demand to Surge — Nuclear Energy Key, but Supply Challenges
The US is on the brink of an unprecedented rise in electricity demand, with projections showing a 35 to 50 percent increase by 2040, according to data from S&P Global Commodity Insights.
This surge, largely driven by artificial intelligence (AI) data centers, manufacturing expansion and mass electrification, underscores an urgent need for a diversified energy strategy.
While renewable energy and natural gas will both play vital roles, nuclear power is emerging as a key component — though its growth may be constrained by uranium supply challenges.
Nuclear energy’s key role in electricity supply
As demand for electricity skyrockets, nuclear power is positioned as a crucial solution due to its reliability and ability to provide continuous, carbon-free energy. Industry leaders stress that without significant investment in nuclear infrastructure and uranium supply chains, the US could struggle to sustainably meet its energy needs.
John Kotek, senior vice president of policy and public affairs at the Nuclear Energy Institute, one of the groups that commissioned the S&P study, emphasized nuclear energy’s potential, stating, “The S&P Demand Growth Report highlights the tremendous growth in electricity demand and the critical gaps that must be filled to meet future needs.”
He added that nuclear power is well positioned to serve power needs from the manufacturing sector, as well as AI and data center demand. Kotek also pointed to growing partnerships between nuclear energy producers and major tech firms like Amazon (NASDAQ:AMZN), Microsoft (NASDAQ:MSFT), Meta Platforms (NASDAQ:META) and Google (NASDAQ:GOOGL), which require reliable around-the-clock power for their AI data centers.
However, uranium supply constraints could present long-term challenges. The nuclear fuel cycle depends heavily on uranium market stability, and geopolitical factors could further complicate sourcing. According to the World Nuclear Association, global uranium production has struggled to keep pace with growing demand.
In 2022, uranium mines supplied only 74 percent of power utilities’ annual needs, with the remainder coming from secondary sources such as stockpiled reserves and recycled materials. The depletion of these reserves over time, combined with increasing nuclear energy adoption worldwide, could stress uranium supply chains.
At the end of 2022, uranium stockpiles stood at approximately:
- 36,000 metric tons in Europe
- 40,000 metric tons in the US
- 132,000 metric tons in China
- 49,000 metric tons in the rest of Asia
China and Russia have taken steps to secure long-term uranium supply, with China investing in mines across Niger, Namibia, Kazakhstan, Uzbekistan and Canada. Russia’s ARMZ Uranium Holding acquired Uranium One in 2013, ensuring a steady uranium flow for its domestic reactors. The US and Europe, by contrast, rely more heavily on market-driven supply chains, making them more vulnerable to price…
