AI Increases Productivity, And That Comes With Energy Costs

Artificial intelligence doesn’t just consume energy via data centers and hardware. It also increases productivity, which comes with its own energy and emissions costs.

Artificial intelligence doesn’t just consume energy via data centers and hardware. It also increases productivity, which comes with its own energy and emissions costs.

A new study from Georgia Tech’s Jimmy and Rosalynn Carter School of Public Policy is one of the first to estimate how changes in productivity due to AI will affect energy consumption.

The paper, written by Anthony Harding and co-author Juan Moreno-Cruz at the University of Waterloo, suggests that greater productivity due to AI will result in a 0.03% annual increase in energy use in the United States and a 0.02% increase in CO2 emissions. That’s about equal to the yearly electricity use of a mid-sized U.S. city.

“If AI is as transformational as some expect it to be, it makes it even more important to think about the knock-on effects throughout the economy, beyond just the demands of the technology itself,” Harding said. “U.S. energy demand has stabilized since the mid-2000s. There is potential for AI to disrupt this, but there is also large uncertainty.”

She received the 2022 Capital CIO Large Enterprise ORBIE Award and has earned numerous honors, including Washington, D.C.’s Top 50 Women in Technology for 2015 and 2016; Computerworld’s Premier 100 Technology Leaders for 2016; StateScoop’s Top 50 Women in Technology list for 2017; FedScoop’s Golden Gov Executive of the Year in 2016 and 2021; and FedScoop’s Best Bosses in Federal IT 2022.  

Dunkin holds a master of science degree and a bachelor of industrial engineering degree, both from Georgia Tech. She is a licensed professional engineer in California and Washington state. In 2018, she was inducted into Georgia Tech’s Academy of Distinguished Engineering Alumni. 

Below is a short Q&A with Dunkin reflecting on how the Institute influenced her career.

  • How did your Georgia Tech education shape your approach to leadership and innovation throughout your career?

    My Georgia Tech education instilled the core ideas and values that we see in our graduates today, and that made me successful in my career. You can’t graduate from Georgia Tech without learning how to be part of a team and to lead through influence, which may be the hardest part of leadership. It’s far easier, although less effective, to lead through authority. In addition, the concept of grit has informed my approach to my roles — that my team and I will work hard together to find solutions to difficult challenges and that no challenge is too hard if we set our minds to accomplishing it. This may seem like an unusual connection to innovation, but it’s not. A lot of people think that innovation is about a light bulb going off in your head with a great idea. Sure, that happens sometimes. But the idea is only the spark of innovation. Innovation is about the hard work to turn an idea into reality — and that’s why it takes grit. You have to do the work and not be discouraged by setbacks.  

  • What does it mean to you to return to Georgia Tech as a distinguished external fellow?

    First, coming back to Georgia Tech feels like the ultimate full circle moment. It’s an honor to be invited back as a distinguished external fellow and a distinguished professor of the practice. It shows that the leadership team at Georgia Tech, one of the best engineering institutions in the world, respects the work that I’ve done in my career. Second, this is an exciting opportunity to shift gears in my career, continue to do interesting work, and contribute at a high level. I’m excited to be here and look forward to what we’re going to accomplish together. 

  • What aspect of your collaboration with the SEI are you most passionate about?

    There are so many things that it’s hard to identify just one. The SEI is at the center of the future of energy, working to solve difficult problems to ensure that we have abundant, affordable, clean energy. During my time at the Energy Department, I developed a strong interest in energy technology, including next-generation nuclear, fusion, and battery technologies. I’m also interested in grid resilience, particularly permitting, planning, and cybersecurity. I hope to help the SEI deepen collaboration with the Energy Department’s labs and to engage other partners as well.

  • How do you see the SEI influencing the energy landscape of our nation?

    The SEI has the ability to influence at a level that exceeds its size. It can drive collaboration between Georgia Tech, national labs, and the private sector on critical issues in the energy sector from research to implementation. I like that the SEI embraces its role as a convener, bringing all the parties together to make something happen.

New Method Uses Collisions to Break Down Plastic for Sustainable Recycling

The high impact between the metal balls in a ball mill reactor and the polymer surface is sufficient to momentarily liquefy the polymer and facilitate chemical reactions.

The high impact between the metal balls in a ball mill reactor and the polymer surface is sufficient to momentarily liquefy the polymer and facilitate chemical reactions.

While plastics help enable modern standards of living, their accumulation in landfills and the overall environment continues to grow as a global concern.

Polyethylene terephthalate (PET) is one of the world’s most widely used plastics, with tens of millions of tons produced annually in the production of bottles, food packaging, and clothing fibers. The durability that makes PET so useful also means that it is more difficult to recycle efficiently.

Now, researchers have developed a method to break down PET using mechanical forces instead of heat or harsh chemicals. Published in the journal Chem, their findings demonstrate how a “mechanochemical” method — chemical reactions driven by mechanical forces such as collisions — can rapidly convert PET back into its basic building blocks, opening a path toward faster, cleaner recycling.

Led by postdoctoral researcher Kinga Gołąbek and Professor Carsten Sievers of Georgia Tech’s School of Chemical and Biomolecular Engineering, the research team hit solid pieces of PET with metal balls with the same force they would experience in a machine called a ball mill. This can make the PET react with other solid chemicals such as sodium hydroxide (NaOH), generating enough energy to break the plastic’s chemical bonds at room temperature, without the need for hazardous solvents.

“We’re showing that mechanical impacts can help decompose plastics into their original molecules in a controllable and efficient way,” Sievers said. “This could transform the recycling of plastics into a more sustainable process.”

Mapping the Impact

In demonstrating the process, the researchers used controlled single-impact experiments along with advanced computer simulations to map how energy from collisions distributes across the plastic and triggers chemical and structural transformations. 

These experiments showed changes in structure and chemistry of PET in tiny zones that experience different pressures and heat. By mapping these transformations, the team gained new insights into how mechanical energy can trigger rapid, efficient chemical reactions.

“This understanding could help engineers design industrial-scale recycling systems that are faster, cleaner, and more energy-efficient,” Gołąbek said.

Breaking Down Plastic

Each collision created a tiny crater, with the center absorbing the most energy. In this zone, the plastic stretched, cracked, and even softened slightly, creating ideal conditions for chemical reactions with sodium hydroxide.

High-resolution imaging and spectroscopy revealed that the normally ordered polymer chains became disordered in the crater center, while some chains broke into smaller fragments, increasing the surface area exposed to the reactant. Even without sodium hydroxide, mechanical impact alone caused minor chain breaking, showing that mechanical force itself can trigger chemical change.

The study also showed the importance of the amount of energy delivered by each impact. Low-energy collisions only slightly disturb PET, but stronger impacts cause cracks and plastic deformation, exposing new surfaces that can react with sodium hydroxide for rapid chemical breakdown. 

“Understanding this energy threshold allows engineers to optimize mechanochemical recycling, maximizing efficiency while minimizing unnecessary energy use,” Sievers explained.

Closing the Loop on Plastic Waste

These findings point toward a future where plastics can be fully recycled back into their original building blocks, rather than being downcycled or discarded. By harnessing mechanical energy instead of heat or harsh chemicals, recycling could become faster, cleaner, and more energy-efficient.

“This approach could help close the loop on plastic waste,” Sievers said. “We could imagine recycling systems where everyday plastics are processed mechanochemically, giving waste new life repeatedly and reducing environmental impact.”

The team now plans to test real-world waste streams and explore whether similar methods can work for other difficult-to-recycle plastics, bringing mechanochemical recycling closer to industrial use.

“With millions of tons of PET produced every year, improving recycling efficiency could significantly reduce plastic pollution and help protect ecosystems worldwide,” Gołąbek said.
