I gave a virtual keynote today for the iTherm 2021 technical conference, focusing on misconceptions about electricity use and emissions associated with computing

I presented nine different high-profile misconceptions about electricity use and emissions associated with computing, explored four pitfalls that lead to such misconceptions, and suggested four ways we can do better in the future.

Here is the conclusions slide:
