This report is a comprehensive analysis of the transition to 24/7 clean energy in the Asia-Pacific and Japan (APJ) region, focusing on the role of hyperscale data centres (HDCs) in this process. It outlines the necessity for collaboration across six key areas to achieve clean energy goals. The report details the current state of energy consumption by data centres, which account for approximately 1% of global electricity use, and emphasizes the need for a shift from volume matching to a 24/7 clean energy model. It discusses the challenges faced in the APJ region, such as limited availability of carbon-free energy and the high costs associated with renewable resources. The report also highlights the commitments made by major technology companies to reduce greenhouse gas emissions and achieve net zero by 2050. Furthermore, it presents potential technology pathways, costs, and sourcing options for achieving 24/7 clean energy by 2030 across key markets including Australia, Singapore, Japan, and Malaysia.
