UK Data Centres Waste 37% of Energy on Overhead: The Engineering Case for Next-Generation Thermal and Power Architecture

UK data centres operate at an average PUE of 1.58, squandering more than a third of total energy consumption on cooling and power distribution losses. This article examines the engineering principles behind liquid cooling architectures, DC microgrid distribution, and AI-driven thermal management that are redefining what operational efficiency looks like in high-density compute environments.
