The frenzy over new projections of electricity growth continues to escalate. This excellent episode of the Energy Transition Show is the best counterweight to that crisis mentality that I’ve found. The show notes themselves are extensive for those who want to dig in further. Short summary: There are many
Read moreI worked with a stellar team of the world’s top experts on computing’s effect on energy and emissions to craft this commentary for Nature, which came out today (April 22, 2024): Luers, Amy, Jonathan Koomey, Eric Masanet, Owen Gaffney, Felix Creutzig, Juan Lavista Ferres, and Eric Horvitz. 2024.
Read moreThis conversation was a fun one. here’s the description: Will the rise of machine learning and artificial intelligence break the climate system? In recent months, utilities and tech companies have argued that soaring use of AI will overwhelm electricity markets. Is that true — or is it a sales pitch
Read moreIn 2011, we replaced lighting cans with LED inserts in our house, instantly reducing lighting energy use by 50% or more. The inserts looked like the ones on the left in the photos below. Recently (September 2023) I needed to buy a few more to replace some of the old
Read moreEvery year since Chris Nelder started the Energy Transition Show, he’s interviewed me for the annual roundup episode, and this year is no exception. We discuss the proper role of government in a capitalist economy, climate change doomism, how the fossil fuel industry rigs the system, and the difficulties
Read moreI, along with colleagues at World Resources Institute and Koomey Analytics, just had a commentary published in WIRES Climate Change. It’s titled “Abandon the idea of an ‘optimal economic path’ for climate policy”. Many economic modelers think that if given enough time, money, graduate students, and coffee they can
Read moreA quarter century ago, Arnulf Grübler published a book titled Technology and Global Change. On June 19th and 20th, 2023, students and colleagues of Arnulf gathered at Oxford for a symposium to honor him and discuss data and methods for understanding technology and global change for the next twenty five
