O TYM ODCINKU
In this episode I talk to Dr. Eric Masanet. Eric is the Professor and Mellichamp Chair in Sustainability Science at the University of California Santa Barbara. The core focus of the episode is Data Centers. In the episode we start at a high level where Eric defines what a Data Center is, the stakeholders of a Data Center, GPU vs CPU compute, the lifecycle of chips, the potential energy efficiency gains of compute, Data Center water usage, the sparse data on Data Centers and the best and worst case scenarios for Data Center sustainability in the future. I hope you enjoy!
