ECE Seminar [ https://ece.princeton.edu/events/sustainable-computing-implications-challeng... | Sustainable Computing: Implications, Challenges, Opportunities | Electrical and Computer Engineering (princeton.edu) ] Speaker: Udit Gupta, Cornell Tech. Title: Sustainable Computing: Implications, Challenges, Opportunities Day: November 10, 2023 Time: 2:00 – 3:30pm Location: Room 004, Friend Center. Host: David Wentzlaff Abstract: Computing has a substantial environmental impact, with far-reaching consequences. Information and Communication Technologies (ICT) alone contribute to 4% of global carbon emissions, a figure equivalent to the aviation industry's carbon footprint. This impact is poised to increase as the demand for computing continues to surge, particularly at the edge and within massive hyperscale data centers. Creating environmentally sustainable computing solutions presents unique challenges that go beyond energy efficiency optimization. It necessitates a holistic approach that considers various factors. For example, sustainable computing devices must account for the carbon emissions generated during the manufacturing process, the influence of renewable energy sources that fluctuate by location and time on a system's operational emissions, and the intricate interplay between embodied and operational emissions. In this presentation, we will delve into recent breakthroughs and the research challenges we confront as we strive to transition to environmentally responsible computing systems. With a primary focus on the carbon footprint of computing, we will explore recent initiatives aimed at characterizing and comprehending the environmental impact of computing. We will also introduce new carbon accounting models and frameworks, highlighting their application in pertinent domains, such as AI, to promote the development of sustainable AI solutions.
