For our second special for Earth Week, we are talking to Bilge who works as a research scientist at Meta AI. Her open-source project Carbon Explorer evaluates solutions to make data centres operate on 24/7 renewable energy. Why this is easier said than done and how engineers can help within their day-to-day work to reduce their carbon footprint are among the many things Pascal and Bilge discuss in this episode.   Got feedback?
