Abstract

The twenty-first-century digitalization wave, propelled by cloud computing, big data, and generative artificial intelligence, has established data centers as critical infrastructure underpinning the global digital economy. Their energy consumption has surged from 80 TWh in 2000 to 620 TWh in 2024, currently accounting for 0.43% of global primary energy, with projections of reaching between 1,000 and 1,600 TWh by 2030. This article presents a literature review of data center energy consumption and the principal efficiency strategies available, covering cooling techniques, hardware optimization, workload orchestration, and renewable energy integration. The findings highlight significant technical advances alongside persistent regulatory gaps and geographic disparities that demand targeted public policy responses.
