In this episode I talk with Dr. Jonathan Koomey, the founder of Koomey Analytics and a former researcher & scientist at Lawrence Berkeley National Laboratory. The focus of this episode is on data centers.

We first start with Jon’s interest in the history of science which he studied at Harvard for his undergraduate. We go over Jon’s PhD thesis on why cost-effective energy efficiency measures may not be adopted in new office buildings. Then we get to data centers. Jonathan discusses the difficulties in obtaining the energy usage data for data centers, the tradeoff between innovation & understanding energy use, limitations of AI in research, a phenomenological model named Koomey’s law that Jon developed, GPUs, software to develop more energy efficient AI models, energy efficient vs inefficient data centers, how companies decide where to build data centers & much more. I hope you enjoy!
