The rapid expansion of data centers across the U.S. and the critical role of renewable energy in powering the grid

By Norm Russell, Chief Revenue Officer, American Wire Group

The demand for data centers across the U.S. is surging at an unprecedented rate, driven by advancements in Artificial Intelligence (AI), cloud computing, e-commerce, and the ever-growing need for digital storage. This demand has generated an unprecedented demand for power and connectivity, and raises critical concerns about energy consumption, sustainability, and how to meet these needs.

Renewable energy has emerged as the most cost-effective and environmentally responsible solution to meet the rapidly growing power supply demand.

Data Center Growth Trends

Data centers are proliferating in major metropolitan areas and rural regions alike. Key factors driving their growth include:

• Cloud Adoption: Increased reliance on cloud-based services.
• 5G Deployment: More connected devices demanding low latency.
• AI Workloads: Advanced computing needs requiring high energy.
• Remote Work: The shift to virtual collaboration increasing demand.

The rise of AI and machine learning has further intensified the need for high-performance computing, increasing energy consumption per facility. Recent projections indicate that the U.S. will need to build at least 1,000 additional large-scale data centers within the next decade to meet the increasing demand.

Virginia is the largest data center market in the world with over 500 data centers and is home to 35 percent of all known hyperscale data centers worldwide. Texas, Ohio, Arizona, and Georgia are emerging as major data center destinations due to their lower land costs, favorable tax incentives, and growing access to renewable energy sources. However, as new data centers come online, their electricity demand is placing unprecedented pressure on the nation’s power grid.

Empowering the Digital Revolution

According to the Department of Energy (DOE), it’s estimated that data centers in the U.S. currently account for 4 percent of the country’s total electricity consumption. This number is expected to rise to between 6.7 percent and 12 percent by 2028.

Ensuring a stable and sustainable power supply for these centers is a top priority. Traditional fossil fuel-based energy sources, while historically reliable, are increasingly being replaced by renewable alternatives due to both cost and environmental concerns. Many states are implementing stricter carbon reduction goals, and major corporations—including data center operators—are committing to ambitious sustainability targets. As a result, renewable energy has become the preferred solution for powering these critical facilities.

Power Demand and Renewable Energy Integration

Wind and solar power have seen dramatic cost reductions over the past decade, making them more affordable than traditional fossil fuel power generation in many regions.     According to the DOE, the levelized cost of electricity (LCOE) for utility-scale wind and solar is now lower than that of coal and natural gas in many parts of the country.

Additionally, renewable energy projects benefit from long-term price stability. Unlike fossil fuels, which are subject to volatile market fluctuations, renewable energy sources provide a predictable and stable cost structure. This is particularly appealing for data center operators, who require reliable and cost-effective power to maintain operations.

Many of the nation’s leading data center operators have already embraced renewable energy through direct power purchase agreements (PPA) with wind and solar farms. These agreements allow companies to secure long-term access to clean energy at fixed prices, reducing their exposure to energy market volatility, while also supporting sustainability goals.

Grid modernization efforts, including energy storage solutions and improved transmission infrastructure, will play a crucial role in ensuring a stable and resilient energy supply. Battery storage technologies are advancing rapidly, helping to mitigate the intermittency of renewables by storing excess power during peak generation periods and distributing it when demand is high.

Collaboration between data center operators, utilities, and policymakers will be key in facilitating this transition. Continued investment in renewable energy infrastructure, coupled with regulatory support for clean energy initiatives, will ensure that the digital economy can continue to grow sustainably.

The Role of Wire & Cable

Data centers rely on a diverse range of wires and cables to maintain uninterrupted operation. From fiber optic and data cables to low- and medium-voltage power cables, a robust infrastructure is essential for efficiency and scalability.

Wires and cables are critical to data center infrastructure, supporting both power transmission and data connectivity.   As renewable energy integration increases, durable, high-performance cables are vital to ensuring system reliability and operational efficiency.

Outlook

The rapid expansion of data centers across the U.S. underscores the urgent need for sustainable and reliable power solutions. As demand for digital services accelerates, integrating renewable energy into the power supply has become not just an option, but a necessity. The role of renewables and cable technologies will become even more intertwined. Innovations in wire and cable solutions, energy storage, and smart grids will play a crucial role in shaping the future of sustainable data centers.
