• Data centres in the US are projected to consume up to 9% of the nation’s electricity by 2030, marking a significant increase from current levels of around 2%.
  • Factors driving this surge include the rapid growth of AI, IoT devices, and 5G networks, which require substantial computational power and data processing capabilities.
  • Urgent measures are needed to enhance energy efficiency, promote renewable energy adoption, and develop innovative cooling technologies to mitigate the environmental impact of expanding data centre operations.

A new report from the Advanced Research Institute for Sustainable Energy (ARISE) has projected a significant increase in electricity consumption by data centres across the United States.

Projected energy consumption

The study indicates that data centres could account for as much as 9% of the nation’s total electricity usage by the year 2030. This figure represents a substantial rise from current levels, underscoring the rapid expansion of digital infrastructure and the growing demand for data processing and storage.

Data centres, the backbone of the digital age, house the servers and networking equipment that power everything from cloud services to social media platforms and streaming services. As more aspects of daily life and business operations migrate online, the energy requirements of these facilities have soared. Currently, data centres are estimated to consume about 2% of U.S. electricity.

Drivers of demand

The ARISE report highlights several key drivers behind this surge in electricity usage. One major factor is the proliferation of artificial intelligence (AI) and machine learning technologies, which require immense computational power. Additionally, the increasing adoption of Internet of Things (IoT) devices and the expansion of 5G networks are contributing to the heightened demand for data processing capabilities.

Call for sustainability

Despite advancements in energy efficiency, such as improved cooling technologies and more efficient server hardware, the sheer scale of data centre operations is outpacing these gains. The report calls for urgent action to address the environmental impact of this trend. Without significant interventions, the environmental footprint of data centres could negate progress in other areas of energy conservation and climate change mitigation.

“We are at a critical juncture,” said Dr. Emily Thompson, lead author of the ARISE study. “The digital economy is growing rapidly, and with it, the energy demands of data centres. It’s imperative that we invest in sustainable energy solutions and more efficient technologies to manage this growth responsibly.”

The report suggests several strategies to mitigate the environmental impact of data centres. These include increasing the use of renewable energy sources, implementing more aggressive energy efficiency measures, and developing innovative cooling solutions to reduce electricity consumption. Additionally, the report advocates for policies that incentivise the construction of data centres in regions with abundant renewable energy resources.

Industry leaders have acknowledged the challenges outlined in the ARISE report. Companies like Google, Microsoft, and Amazon, which operate some of the largest data centres in the world, have already committed to ambitious sustainability goals. For example, Google aims to operate on carbon-free energy by 2030, and Microsoft has pledged to be carbon negative by the same year.

However, experts warn that achieving these targets will require coordinated efforts across the industry and substantial investment in new technologies. “The transition to a more sustainable digital infrastructure is not just the responsibility of individual companies,” noted Dr. Thompson. “It requires a comprehensive approach involving policymakers, technology developers, and energy providers.”

As the U.S. prepares to meet the challenges of a digitally-driven future, the findings of the ARISE report serve as a stark reminder of the need for sustainable growth in the technology sector. The projected 9% electricity consumption by data centres by 2030 is a call to action for both industry and government to prioritise energy efficiency and renewable energy in their planning and operations.
