Our planet is experiencing worldwide growth in energy consumption and CO2 emission and is experiencing temperature rise and climate change at an accelerating rate. This video introduces the Institute for Energy Efficiency at UC Santa Barbara and describes a path to reducing our energy consumption and CO2 emission. In his talk, John Bowers, Director of the Institute of Energy Efficiency and Professor of Electrical and Computer Engineering and Materials, discusses the evolution of photonics and what the future holds for more efficient, higher capacity data centers, which are important for machine learning and data processing.
