The UK's ambitions in the field of artificial intelligence (AI) are raising concerns about potential water shortages triggered by the significant amounts of water needed to cool data centres. As the demand for data processing and storage grows with the advancement of AI technologies, so does the requirement for water to keep these data centres functioning. However, the sources of this water are not clearly defined, prompting worries about the implications for local water supplies. This issue underscores the importance of considering the environmental impact of technological advancements and the need to develop sustainable solutions to support the growth of AI infrastructure.
