AI Is Fueling Sustainability Concerns for Big Tech–But Might Be Cure, Too, Experts Reveal

Summary

April 8, 2025 - Artificial intelligence (AI) continues to develop rapidly, and there are concerns about its environmental footprint. According to a recent WTW report, the growth of data centers harms the sustainability goals of technology firms such as Google, Amazon or Microsoft. These centers currently consume 6% of all electricity in the US and are expected to double by 2026.

However, according to energy experts from Exergio–a company that develops AI-based tools for energy optimization in commercial buildings–while AI wastes a lot of energy, existing tools can already be used to cut that waste.

"The common narrative suggests that AI's growth contradicts the urgent need to reduce greenhouse emissions," said Donatas Karčiauskas, CEO of Exergio. "However, this overlooks the fact that certain AI tools are already helping multiple industries cut energy waste. And not just more affordably, but also faster and more precisely than other existing traditional methods such as rule-based automation, manual energy audits or reactive maintenance. Big tech has to simply utilize it."

Optimization of energy consumption in property management

According to Karčiauskas, the buildings sector can be used as an example. It is a major energy consumer, responsible for about 40% of global energy usage and 33% of greenhouse gas emissions. Inefficiencies in heating, ventilation and air conditioning (HVAC) systems cause buildings to consume more energy.

Currently existing AI solutions, however, are able to rearrange the concept of how energy can be managed in properties. They analyze real-time data and then optimize HVAC operations, lighting and other energy-intensive systems.

For example, AI can predict occupancy patterns and adjust heating and cooling systems accordingly.

"It’s a common misconception that AI just wastes–this technology, in such cases, also ensures that energy is used only where and when it’s needed. Numbers-wise, it depends on the project, but it could reach up to 29%," continued Karčiauskas.

How to improve energy efficiency in smart grids and cities

Focus for AI potential can be expanded from individual buildings to entire urban areas. Currently, similar technologies are being used in the development of smart grids and cities to optimize energy consumption. A smart grid is an electricity supply network that uses digital communications technology to detect and react to local changes in usage.

Indeed, smart grids primarily integrate AI to upgrade energy distribution. A study published in the International Journal of Communications, Network and System Sciences showed that smart grid implementation manages to reduce electricity transmission losses by up to 20%.

After analysis of historical consumption patterns, AI systems can predict fluctuations in energy demand, and enable utilities to adjust power flows dynamically–a process similar to what happens in buildings. Further from grids, AI is also used in weather monitoring, which is then integrated into building systems.

“In the past, we’ve been used to reactive decisions. The industry is shifting towards learning, analyzing and predicting now,” continued Karčiauskas. “In some cities, weather analysis can inform building owners on how to better anticipate energy demand, mitigate extreme weather impacts and optimize renewable energy use. As AI models become more sophisticated, we’ll see even greater precision in how we balance sustainability with energy efficiency.”

Integrating AI-driven weather prediction into building management systems directly improves energy efficiency. This way, AI enables proactive adjustments to HVAC operations. According to a Nature study, adopting AI technology at scale and combining it with existing energy policies and low-carbon power generation could lead to 90% lower carbon emissions.

Scaling automation is the next step

According to energy experts, scaling such technologies will be crucial to make an impact. Here, robotics are being utilized as a technology that could scale AI-based tools and apply them in different environments.

“Even though AI-powered robotics are mostly used for domestic tasks and mundane jobs that are dangerous for humans, in the future they will be trained to achieve sustainability by automating tasks, especially in buildings,” said Karčiauskas. “Imagine if an HVAC sensor gets faulty–a robot gets notified, moved to a specific location and gets to fix the problem in the end."

While AI-powered robotics have already transformed industries like manufacturing and logistics, their role in the building sector’s energy management is still in the early stages.

“We’ve started training a humanoid robot that will be based on the NVIDIA GR00T system as well. This only feels natural. After years of collecting energy consumption data in the buildings industry, and learning how to utilize it, we see how AI-based technologies can help us take it to the next level," concluded Karčiauskas.
