TADEAS: mann re gates
You can’t reboot the planet if you crash it
https://thebulletin.org/2025/10/you-cant-reboot-the-planet-if-you-crash-it/I became concerned about Gates’ framing of the climate crisis nearly a decade ago when a journalist reached out to me, asking me to comment on his supposed “discovery” of a formula for predicting carbon emissions. (The formula is really an “identity” that involves expressing carbon emissions as a product of terms related to population, economic growth, energy efficiency, and fossil fuel dependence). I noted, with some amusement, that the mathematical relationship Gates had “discovered” was so widely known it had a name, the “Kaya identity,” after the energy economist Yōichi Kaya who presented the relationship in a textbook nearly three decades ago. It’s familiar not just to climate scientists in the field but to college students taking an introductory course on climate change.
If this seems like a gratuitous critique, it is not. It speaks to a concerning degree of arrogance. Did Gates really think that something as conceptually basic as decomposing carbon emissions into a product of constituent terms had never been attempted before? That he’s so brilliant that anything he thinks up must be a novel discovery?
I reserved my criticism of Gates, at the time, not for his rediscovery of the Kaya identity (hey—if can help his readers understand it, that’s great) but for declaring that it somehow implies that “we need an energy miracle” to get to zero carbon emissions. It doesn’t. I explained that Gates “does an injustice to the very dramatic inroads that renewable energy and energy efficiency are making,” noting peer-reviewed studies by leading experts that provide “very credible outlines for how we could reach a 100 percent noncarbon energy generation by 2050.”
The so-called “miracle” he speaks of exists—it’s called the sun, and wind, and geothermal, and energy storage technology. Real world solutions exist now and are easily scalable with the right investments and priorities. The obstacles aren’t technological. They’re political.
Gates’ dismissiveness in this case wasn’t a one-off. It was part of a consistent pattern of downplaying clean energy while promoting dubious and potentially dangerous technofixes in which he is often personally invested. When I had the chance to question him about this directly (The Guardian asked me to contribute to a list of questions they were planning on asking him in an interview a few years ago), his response was evasive and misleading. He insisted that there is a “premium” paid for clean energy buildout when in fact it has a lower levelized cost than fossil fuels or nuclear and deflected the questions with ad hominem swipes.
