Denmark | Researchers at Technical University of Denmark are drawing attention to the growing environmental and climate impact of artificial intelligence as its global use continues to expand.AI has rapidly become a part of everyday life, powering tools for translation, content creation, and data analysis. However, experts warn that this convenience comes with hidden costs, particularly in the form of energy and water consumption required to operate large-scale data centres.According to DTU researchers, the increasing demand for AI is driving the rapid construction of data centres worldwide. These facilities require massive amounts of electricity and water, especially for cooling systems. Studies suggest that training large AI models can consume millions of litres of fresh water, while future global AI demand could significantly increase overall resource usage.The expansion of data centres is also raising environmental concerns. In some regions, opposition is growing due to the strain on local energy supplies and water resources. Projections indicate that by 2050, data centres could account for a substantial share of national electricity consumption in countries like Denmark.Despite these challenges, researchers emphasize that AI also offers significant benefits. It plays a key role in scientific discovery, including identifying new materials, improving health research, and advancing sustainable technologies such as Power to X solutions.The debate within the research community reflects two perspectives: one highlighting AI as a major environmental burden, and the other pointing out its potential to replace more resource-intensive processes. Experts agree that better data, transparency, and regulation are essential to fully understand and manage AI’s environmental footprint.Efforts are now underway to develop standardized methods for measuring the climate impact of digital technologies. These tools could help companies and consumers make more informed, environmentally responsible choices in the future.
