The document discusses strategies for data centers to achieve net zero emissions. It notes that over 40% of the world's electricity comes from coal and nearly all of a data center's heat is wasted. To become net zero, data centers can use renewable energy sources like wind and solar, recover waste heat, and implement energy efficiency practices. Locating in areas with abundant renewable resources and connecting to district heating networks supports net zero goals. While challenging, the document concludes that approaching net zero for data centers is feasible through strategic use of renewable electricity, energy recycling, and considering location and operations.
