The United States’ power demand is growing at an unprecedented rate, but the nation is struggling to deliver reliable power, raising concerns for businesses, policymakers, and the general public. Although energy production is at historically high levels, power demand is expected to increase by at least 50% in the next quarter-century. This will create considerable strain on our existing power infrastructure, which is already struggling to keep pace with current demands.
In 2023 alone, the United States consumed more than 4,000 terawatt-hours (TWh) of electricity, with transportation accounting for the largest share at 37%, powering cars, aircraft, trains, buses, and ships. Commercial use accounted for the smallest share of demand but still made up 13%, supporting offices, schools, hospitals, hotels, restaurants, and other facilities. Unfortunately, forecasts suggest the country will need more than 5,100 TWh of power by 2050 to continue to effectively support economic activity and daily life.
What’s driving power demands?
The rapid electrification of the economy is one of the most significant factors driving power demand. For example, the rapid adoption of electric vehicles (EVs) is projected to add 185 TWh to the national electricity consumption over the next four years. Another accelerating force is the rise of artificial intelligence (AI) and data centers, which consume an extraordinary amount of energy to operate. Roughly 1.5 million AI server units are expected to be operating nationwide by 2027, potentially consuming at least 85 TWh of electricity each year. At full capacity, global data centers could rival the annual power consumption of small nations, and the energy needed to keep AI servers cool could increase energy costs by more than 50%.
However, many issues could arise if energy demand outpaces supply. Without reliable electricity, critical systems and services could fail almost immediately. Fuel might not be accessible at gas stations, crippling transportation networks. Communication systems could fail, making it difficult to access information or contact necessary services. Supply chain operations could halt, disrupting the distribution of food, medicine, and other provisions. Banking systems could stop operations, limiting access to credit card processing and point-of-sale systems that businesses rely on.
The inefficient power grid
One significant concern is the existing inefficiencies of the current power grid. Between 2018 and 2022, about 5% of electricity transmitted and distributed nationwide was lost each year due to outdated infrastructure. If we use 2025 numbers, that annual loss amounts to nearly 203 TWh, which is enough to power at least 202 million homes, cool over 101 million homes, and sustain more than 14 million households.
Upgrading the nation’s electrical infrastructure could address the inefficiencies of the current power grid, but doing so is tricky and costly. Much of the grid is already 40 to 70 years old, with about 70% of transmission lines being over 25 years old and nearing the end of their expected service life. Aging transmission lines increase the risk of power outages, cyberattacks, and other emergencies caused by structural failures.
Additional vulnerabilities exist in other important sections of the system. Only a few of the more than 55,000 U.S. substations are staffed, which can result in those substations being attacked, leaving thousands of homes and businesses without power.
Aging power transformers
Power transformers play an important role in distributing electricity, but they are also aging quickly. There are currently around 70 million distribution transformers, but demand could increase by as much as 260% by 2050. Furthermore, almost 60% of residential transformers are approaching the end of their useful lives, with most units at least four decades old. The multiple issues throughout the electricity grid have serious implications for reliability and capacity, especially in the near future.
Replacing or upgrading the old infrastructure is not a straightforward task. The U.S. electrical grid spans more than 470,000 miles, underscoring the immense scope of the work required. In addition, key equipment, such as transformers, has increased significantly in price since 2019, and lead times for both generators and power transformers can extend to two years. Estimates suggest that replacing the whole electrical grid could cost nearly $5 trillion.
Furthermore, there is a backlog of power-generating projects still awaiting clearance to connect to the rest of the grid. In the United States, about 2.6 TWh of generating capacity remains inactive in interconnected queues or projects that have yet to be authorized, with an estimated 80% of these projects eventually being withdrawn due to delays or high costs.
Given the current situation, proactive, systemic solutions are required to see improvements. Exploring alternative energy sources could help diversify supply and reduce dependence on the old, traditional infrastructure. Streamlining interconnection queues could potentially double the nation’s existing power plants by speeding the delivery of new ones and expanding capacity at a faster pace. Working to provide faster lead times and higher-quality essential equipment would also help build a better power infrastructure.
Investing in a more upgraded infrastructure would yield several benefits, such as encouraging more support for clean energy, reducing the frequency of serious power outages, stabilizing energy costs, and fostering a better economy. Moreover, building greater resilience to climate-related disruptions would benefit businesses and communities. Substantial enhancements to the current power grid are increasingly necessary to support economic growth and meet the rising national electricity demands in a world that is relying on electricity like never before.
