Powering the AI revolution: Solving the energy and sustainability puzzle of data centers

In a world increasingly driven by data and digital intelligence, the race to build bigger and faster
AI
models is fundamentally reshaping the
energy
landscape. From powering predictive algorithms to training generative models like ChatGPT,
Artificial Intelligence
(AI) is no longer just a tool—it's the engine behind the modern economy. But this engine has a growing appetite, and at its core lies one of the most energy-intensive infrastructures of the digital age: the data center.
The Surge of AI—and Its Energy Wake
The AI boom is rewriting the rules of infrastructure planning. According to the International Energy Agency (IEA), global data center electricity consumption could double by 2026, reaching over 1,000 terawatt-hours (TWh)—roughly comparable to the annual electricity demand of Japan. This spike is being driven not only by hyperscale cloud providers, but also by a new generation of AI workloads that require massive computing power and near-continuous uptime.
A single AI query can require 10 times more energy than a typical web search. With audio-visual generative tools on the rise, the pressure on energy systems will only intensify. Already, data centers consume about 1.5% of global electricity and contribute to 1% of energy-related greenhouse gas emissions—figures expected to rise sharply as AI adoption scales.
The Power Trilemma: Energy, Carbon, and Water
Behind every AI interaction is a complex physical footprint: rows of processors, high-density cooling systems, and vast power supply chains. Nearly 40% of a data center's electricity goes to computing, and another 40% to cooling. But energy and emissions aren't the only concerns—water use is an emerging and often underappreciated pressure point.
Consider this: a 20-question AI session can indirectly consume about 500ml of water, primarily for cooling. In the U.S., mid-sized data centers can withdraw up to 300,000 gallons of water a day—enough to meet the daily needs of 100,000 households. By 2027, AI-related water withdrawals could reach up to 6.6 billion cubic meters globally, compounding the environmental burden in already water-stressed regions.
This growing trilemma—energy intensity, carbon emissions, and water use—is pushing the industry to rethink how data centers are powered and cooled.
Redefining the Energy Stack: Smarter Solutions for a more sustainable AI
To support AI's exponential growth while meeting
sustainability
targets, the industry is turning to next-generation energy technologies. These innovations are enabling resilient, efficient, and lower-carbon emission power systems—a crucial shift for an AI-driven future.

1. High-Efficiency Turbines for More Sustainable Power
Flexible gas turbine technologies are gaining traction for their ability to help deliver high power -density at a lower-carbon power. GE Vernova's aeroderivative gas turbines, for example, are engineered for high performance with lower emissions, offering the ability to run on natural gas, hydrogen blends, or biofuels. Their modularity and fast ramp-up capabilities make them ideal for powering high-load facilities like AI data centers—especially in regions with constrained grid access or unstable supply.
Just as important, these turbines consume significantly less water than traditional power systems—an advantage in arid zones like India, the Middle East, or sub-Saharan Africa.
2. Resilient Grids and Smart Storage
Reliable power isn't just about generation—grid stability and storage are critical, especially for data centers that can't afford downtime. Integrated systems like GE Vernova's FLEXRESERVOIR provide a modular solution: combining battery storage, inverters, and intelligent energy management systems to help facilities integrate renewables, manage peak loads, and ensure 24/7 uptime.
Such systems are key to balancing AI data center load fluctuations, ensuring power stability, and providing the fast-response backup power to the facilities.
3. Cooling Reinvented: Toward Zero-Water Operations
On the cooling front, innovation is transforming efficiency. Traditional water-intensive methods are giving way to advanced alternatives:
Liquid cooling systems now deliver targeted heat removal at the chip level.
Immersion cooling submerges hardware in specialized fluids, improving performance and slashing water use.
Rear-Door Heat Exchangers allow localized cooling for high-density racks, reducing overall system demand.
These approaches not only boost energy efficiency but also set the stage for near-zero water usage—a breakthrough for future-ready data centers.
Regional Relevance: India as an AI Growth Hub
India is fast emerging as a pivotal AI marketplace. Although it generates nearly 20% of the world's data, it currently hosts only 5.5% of global data center capacity—a stark infrastructure shortfall. This gap is driving a wave of investment, with up to $60 billion expected in cloud and server infrastructure.
'As government policy pushes digitalization and lower-carbon emitting energy systems adoption, India has the potential to become a sustainable data center hub. But doing so will require smart, efficient energy systems that address both power and water constraints—an area where advanced technologies like GE Vernova's turbines and storage platforms can make a meaningful difference.' –

The Path Forward: Building a Sustainable Digital Future
The
AI revolution
is already reshaping economies—but how we power it will define its long-term impact. Solving the Power Trilemma with performance and sustainability demands a hybrid, intelligent energy mix—where flexible generation, renewable integration, and innovative cooling converge.
By deploying scalable solutions tailored to local realities—and by embracing technologies that reduce both emissions and water use—we can build an AI infrastructure that's not just powerful, but planet-positive.
This is the crossroads where AI meets energy innovation. And the future of computing will be shaped by how we solve the puzzle of power.
