  • And that’s how it starts. You add enough wind and solar that they can sometimes provide more electricity than people use. Curtailment orders keep them from causing a problem, but that means wasting otherwise free electricity. So people start installing utility-scale batteries, which soak up that excess, and release it during the morning and evening peaks in net demand. You install even more wind and solar, and people do even more batteries, displacing routine overnight fossil fuel use. Even more wind and solar, and it starts making sense to install low-efficiency long-duration storage, and fossil fuel use disappears completely and permanently.
























  • We are past two important points:

    • we passed the point where you would not be able to tell the difference something like 30 years ago
    • we passed the point where we likely locked in 1.5°C of warming quite recently. That’s roughly where you walk into a minefield of risking major ecosystems with each additional bit of warming, and the stretch goal that small island nations wanted because it might have left them habitable.

    Importantly neither point is one where we expect civilization to suddenly end.
