The AI Energy Challenge: Rethinking Power for the Next Generation

By Pete DiSanto

AI-powered technology is taking over consumer products, from smart assistants to immersive augmented or virtual reality experiences and personalized recommendations. Behind these innovations is a growing concern that is skyrocketing energy consumption.

The paradox is that AI can transform so much of what we do, including how we can approve efficiencies in energy creation and distribution, yet its energy demand is voracious. The industry must adapt, balancing rising power demands with sustainability and grid stability.

The Strain on Data Centers

The large language models (LLMs) powering today’s AI revolution require tremendous computing power. Powered by high-performance hardware like NVIDIA GPUs, these models generate huge power surges in data centers. In certain instances, a single question to ChatGPT alone can cause energy demand to fluctuate by up to 20 to 30 megawatts in less than a minute (five to ten times more than a normal Google search). These sudden fluctuations exert a huge strain on the grid, posing a challenge to conventional power infrastructure.

Data centers, the beating heart of AI, consumed approximately 176 terawatt-hours (TWh) of electricity in 2023, accounting for about 4.4% of total U.S. electricity usage. Scaling up infrastructure requires not only more computing power but also sophisticated cooling systems to handle the intense heat AI workloads generate.

The unpredictable spikes in energy use, cooling requirements and influx of AI technology strain both local electrical grids and backup power sources. In dire need of power, some facilities are turning to liquid and immersion cooling to improve efficiency, but adoption remains slow due to a multitude of challenges. Meanwhile, AI’s breakneck pace forces data centers to stick with conventional (often outdated) designs, like diesel backup power, limiting the industry’s ability to implement more energy-efficient and innovative solutions.

A Grid Under Pressure

The energy grid is the lifeline of AI operations, yet it’s struggling to keep up. In the U.S., data center electricity demand is projected to rise by about 400 TWh between 2024 and 2030, growing at a compound annual rate of 23%.

This rapid expansion threatens grid stability, particularly in regions with aging or limited infrastructure. In California, legislators are considering measures to address the high energy consumption of data centers, aiming to prevent the public from bearing the associated infrastructure costs. Proposed actions include mandating energy-use transparency and establishing efficiency standards.

Renewable energy sources like solar and wind offer potential solutions, yet they aren’t reliable or scalable enough to fully power AI-driven data centers. Solar and wind energy depend on weather conditions, making them inconsistent power sources without significant energy storage capacity.

Not to mention, renewables’ feasibility varies by region. Some areas lack the natural resources to support widespread solar or wind farms. This geographic disparity complicates efforts to integrate sustainable energy solutions on a national scale.

Power constraints for data centers are becoming a bottleneck, increasing operational costs and forcing them to explore alternative solutions like on-site power generation, flexible energy capacities and storage technologies. By adopting a more adaptive approach, data centers could shift from being energy consumers to grid stabilizers.

Finding Smarter Energy Solutions

To meet growing energy demands from the influx of AI-powered consumer technology, data centers are testing a range of solutions. AI itself could help optimize power use by fine-tuning infrastructure layouts, predicting demand and improving energy efficiency. AI development is moving at full speed, however, and energy optimization often takes a back seat to innovation.

New power sources, such as microgrids, small modular nuclear reactors and fuel cells, could help address long-term needs. While nuclear technology remains a decade away from widespread adoption, dispatchable natural gas assets serve as short-term fixes to stabilize AI’s energy footprint and offer a cleaner solution than traditional diesel generators.

The Road Ahead

We’ve grown accustomed to AI-powered conveniences, ChatGPT, smart assistants and personalized recommendations aren’t going anywhere. Once the metaphorical toothpaste is out of the tube, there’s no putting it back. The challenge now is ensuring AI’s growth doesn’t come at an unsustainable cost.

Data centers won’t find a one-size-fits-all energy solution. Instead, the key lies in a tailored, multi-faceted approach, leveraging the best resources available for each region. Batteries, fuel cells and flexible natural gas power will all play a role in building a more resilient energy model. But it’s not just about technology. The industry must rethink its approach, prioritizing long-term reliability over short-term expansion.

The energy demands of AI present a challenge yes, but also an opportunity to change the landscape today. Investing in smarter, more adaptive power solutions now lays the groundwork for a future where AI innovation and energy stability can coexist.
