Over the past two decades, power demand in the United States has been stagnant, with an average annual increase of just 0.04% between 2006 and 2021. This period of quiescence can be attributed to several key factors, including the offshoring of manufacturing, the expansion of energy-light industries, and the implementation of energy-efficiency initiatives.
Innovations such as the shift toward edge computing, which processes information closer to where it is generated on devices such as smartphones, have reduced the reliance on energy-intensive data centres. The widespread adoption of LED lighting, which consumes up to 90% less power than traditional bulbs, and advancements in HVAC systems, which use variable-speed motors and smart thermostats to optimize energy use, have also contributed significantly to energy savings. Such innovations have helped keep power demand flat in the United States for the past 20 years. That being said, we are now witnessing a significant shift in the energy landscape: a megatrend called the electrification of everything. This trend is expected to increase electricity consumption substantially in the coming years, with projections ranging from 2% to 6% average annual growth over the next decade. The forces driving this surge in demand are numerous and interconnected, encompassing the rise of artificial intelligence (AI), the reshoring of manufacturing, the transition to electric vehicles (EVs), the adoption of heat pumps, and the growing need for grid modernization.
The Role of AI and Data Centres in Power Demand Growth
The rapid proliferation of AI, particularly generative AI, has led to an exponential increase in the number and size of data centres. These facilities are voracious consumers of electricity, requiring vast amounts of power for both computational processing and cooling systems. Generative AI models, such as those used for natural language processing, image generation, and other complex tasks, demand significant computational resources. The outcome is a surge in the construction and expansion of data centres to accommodate the growing computational needs.
Data centres are designed to operate continuously, so that AI applications and services are available around the clock. This constant operation requires a reliable and substantial power supply. In addition to the energy needed for computational tasks, data centres consume large amounts of electricity for cooling systems to prevent servers and other equipment from overheating. Advanced cooling technologies, such as liquid cooling and immersion cooling, are being developed to improve energy efficiency, but overall power demand remains high.
As AI adoption continues to accelerate, so too will the energy demands of data centres. Some estimates predict that data centres will account for 6.5% to 7.5% of total U.S. electricity demand by 2030, a significant leap from the 2.5% they consumed in 2022. This rapid growth presents challenges and opportunities for the energy sector. Utilities will need to adapt to meet this surge in demand while ensuring grid reliability and affordability. They will have to upgrade infrastructure, invest in smart-grid technologies, and enhance energystorage capabilities to manage peak loads and maintain a stable power supply.
At the same time, the growing demand from data centres provides a powerful incentive for the development and deployment of renewable-energy sources and other low-carbon solutions. Many datacentre operators are committing to sustainability goals, seeking to power their facilities with renewable energy, such as solar, wind, and hydroelectric power.
This shift not only helps reduce the carbon footprint of data centres but also drives innovation in the renewable-energy sector.
Furthermore, the integration of AI into energy- management systems can optimize the operation of data centres, improving energy efficiency and reducing waste. AI algorithms can predict energy-usage patterns, adjust cooling systems in real time, and manage power distribution more effectively. These advancements contribute to a more sustainable and efficient energy landscape, aligning with the broader goals of reducing greenhouse gas emissions and combatting climate change.
Reshoring Manufacturing and the Impact on Energy Consumption
After years of offshoring, manufacturing is gradually returning to the U.S., driven by policy initiatives, such as President Joe Biden’s “America First” stance and the desire to reduce reliance on global supply chains. This reshoring trend is expected to contribute to a significant increase in industrial electricity demand as factories and production facilities ramp up domestic operations. The return of manufacturing to the U.S. is seen as a strategic move to enhance economic security, create jobs, and stabilize supply chains, especially in critical sectors, such as electronics, pharmaceuticals, and automotive.
Even so, the expected rise in electricity consumption due to reshoring can be mitigated by advancements in manufacturing technologies and energy-efficiency practices. One of the key innovations in this area is the development of smart factories. These facilities leverage automation, the Internet of Things (IoT), and data analytics to optimize production processes and energy use. By integrating sensors and connected devices, smart factories can monitor and control energy consumption in real time, identifying inefficiencies and making adjustments to reduce waste.
Automation plays a crucial role in enhancing energy efficiency in manufacturing. Automated systems can perform tasks with greater precision and consistency than human workers can, reducing errors and minimizing the need for rework. They not only improve productivity but also lower energy consumption. For example, robotic systems can be programmed to operate only when necessary, shutting down during idle periods to conserve energy.
Data analytics further enhances the efficiency of manufacturing operations. By analyzing large volumes of data from various sources, manufacturers can gain insights into energy-usage patterns and identify opportunities for improvement.
Predictive maintenance, enabled by data analytics, allows for timely servicing of equipment before it fails, reducing downtime and the associated energy costs of unexpected breakdowns.
In addition to smart factories, other energy-efficient practices are being adopted to mitigate reshoring’s impact on electricity demand. The use of advanced materials and manufacturing techniques, such as additive manufacturing (3D printing), can reduce energy consumption by minimizing material waste and enabling more efficient production processes. Energy-efficient lighting, HVAC systems, and machinery also contribute to lower overall energy use in manufacturing facilities.
Moreover, the integration of renewable energy sources into manufacturing operations is becoming increasingly common. Distributed energy, which consists of solar panels, wind turbines, and other renewable-energy technologies installed directly on site to generate a portion of the electricity needed for production, provides significant energy cost savings in relation to retail power prices while reducing reliance on the grid and lowering carbon emissions. Such solutions have become even more competitive with the significant cost decreases of solar and wind, whose levelized cost of energy has fallen by 83% and 49%, respectively, over the past 15 years.
Electrification of Transportation and Heating: Driving Power Demand
The transition from fossil fuels to electricity in transportation and heating is a key driver of the projected power-demand growth. Electric vehicles (EVs) are becoming increasingly popular, with sales steadily rising owing to advancements in battery technology, decreasing costs, and growing environmental awareness. As EV adoption accelerates, so too will the demand for charging infrastructure and the electricity needed to power such vehicles. This demand includes not only residential charging stations but also public and commercial charging networks, which require significant investments and expansion to meet the growing needs of EV owners.
Similarly, the adoption of heat pumps, a more efficient and environmentally friendly alternative to traditional heating systems, is also contributing to higher electricity consumption. Heat pumps, which transfer heat from the outside air or ground into buildings, are much more efficient than conventional heating methods, such as oil or gas furnaces. They can provide both heating and cooling, making them a versatile solution for year-round climate control. As more households and businesses switch to heat pumps, the demand for electricity to power these systems will increase, further driving overall power consumption.
The Nuclear Renaissance: A Sustainable Solution for Baseload Power

China and the United States, to cite only two countries, have nuclear power plants under construction, and the International Energy Agency (IEA) has set a goal to triple global nuclear capacity by 2050.
In the United States, the revival of nuclear energy is also marked by the restarting of mothballed plants to meet the increasing power demands of data centres. For instance, in Pennsylvania, a unit of the Three Mile Island nuclear plant, which was shut down in 2019, is set to be restarted under a new energy-sharing agreement with Microsoft. The agreement aims to provide clean, reliable power to Microsoft’s data centres, which are crucial for the company’s AI operations. The reactor’s restart is expected to bring 800 megawatts of power back onto the grid, highlighting nuclear energy’s role in meeting the high energy demands of modern technology infrastructure.
Small Modular Reactors (SMRs): A Potential Game Changer for Data Centres
With traditional large-scale nuclear reactors facing the challenges of high capital costs and lengthy construction timelines, small modular reactors (SMRs) are emerging as a promising alternative, particularly for power-thirsty data centres. SMRs are smaller and potentially more cost-effective than their larger counterparts. Their modular design allows for factory fabrication and assembly, reducing construction time and costs. Moreover, SMRs can be deployed closer to demand centres, minimizing transmission losses and enhancing grid reliability.
SMRs offer several advantages that make them suitable for powering data centres. Their smaller size and modular nature mean they can be built incrementally, allowing for better scalability and flexibility in meeting energy demand. Additionally, SMRs can provide a steady and reliable power supply, which is crucial for data centres, which must operate continuously. Reliability is vital as data centres increasingly become integral to the functioning of AI and other advanced technologies.
Even though SMR technology is still in development, it holds significant potential to revolutionize the way we power data centres and other energy-intensive facilities. By providing a reliable, carbon-free source of energy, SMRs can help meet the growing electricity demands of the digital age while supporting efforts to reduce greenhouse gas emissions.
