The Gist — “Bill McKibben: ‘Energy From Heaven, Not From Hell’”
Date: September 12, 2025
Host: Mike Pesca
Guest: Bill McKibben (environmentalist, author of Here Comes the Sun)
Episode Overview
This episode of The Gist features a probing, cautiously optimistic conversation with pioneering environmentalist Bill McKibben. The dialogue centers on an inflection point for averting climate catastrophe: the rapid, exponential growth in wind and solar energy, and the transformative potential that energy transition holds not just for the planet, but for global politics and society at large. Host Mike Pesca and McKibben discuss hopeful new data, the role of activism and economics, the limits of human consumption changes, and the fraught promises and dangers of geoengineering.
Key Discussion Points & Insights
1. Current Climate Breakthrough: A Surge in Renewables
[15:31 - 18:36]
-
Optimism Amidst Trouble:
Bill McKibben opens by acknowledging his standard pessimism about the planet and democracy—but shares “one big good thing happening,” namely the stunning recent rise of renewables.“I've never been more afraid for my own country, nor really for the state of the physical state of the planet. But there is one big good thing happening amidst all this, and for once, that's the story I get to tell.” — Bill McKibben [15:34]
-
Exponential Growth in Solar, Wind, and Batteries:
- In just the last 36 months, there’s been an “incredible spike” in building solar and wind energy infrastructure (plus batteries).
- In places taking action, carbon emissions are now falling.
- Example: California uses 40% less natural gas to generate electricity than two years ago, despite being the world’s fourth-largest economy.
- China’s carbon emissions have also dropped so far this year.
“The pace at which this is happening is really almost incomprehensible.” — Bill McKibben [16:42]
-
Why Renewables Are Now Unstoppable (Long-Term):
- The cost of generating power from solar and wind is now cheaper than burning fossil fuels.
- Implication: Just as the industrial revolution was fueled by burning fossil fuels, the energy revolution will ultimately be powered by solar and wind.
- The shift disperses power to all corners of the globe, ending domination by fossil-fuel-rich regions.
- Economic momentum is now with clean energy.
“We now all of a sudden live on a planet where the cheapest way to make power is to point a sheet of glass at the sun.” — Bill McKibben [18:52]
- The cost of generating power from solar and wind is now cheaper than burning fossil fuels.
2. How Did We Get Here? Activism and Economics Intertwined
[24:00 - 27:05]
-
Activism Fostered the Breakthrough, Not Just Market Forces:
- Early, costly policy moves—like Germany’s solar buy-back program—stimulated solar manufacturing in China, rapidly slashing costs.
- Without such activism and state intervention, market forces alone might not have driven such a fast transition.
“It created the demand that allowed the Chinese to start getting good at building cheap solar power... a dance between good activism and good engineering all along.” — Bill McKibben [24:37]
-
Fossil Fuel Industry Retaliates:
- With its business model threatened, the fossil fuel industry is using political influence and campaign donations to try and slow renewables, particularly under the Trump administration.
- Example: Sudden stop-work order for a near-finished wind farm off Rhode Island.
- “National security” pretext widely seen as questionable.
- Trump’s explicit offer to oil execs: (“If you give me a billion dollars, you can have anything you want.”) [25:59]
- With its business model threatened, the fossil fuel industry is using political influence and campaign donations to try and slow renewables, particularly under the Trump administration.
3. Political and Geopolitical Ramifications
[27:05 - 29:39]
-
Economic Shift Drives Policy Even in Red States:
- Texas, despite its oil industry, is installing clean energy fastest in the U.S. Recent legislative attempts to require equal buildout of gas with renewables (“DEI for natural gas”) failed because rural communities and businesses value cheap, clean energy.
- Oklahoma’s embrace of wind (“where the wind comes sweeping down the plain”) further demonstrates bipartisan economic appeal.
-
U.S. Risks Losing Technological and Political Leadership:
- China is becoming the “first electrostate” by leading in both energy production and manufacturing for the clean-tech era.
4. Environmental Movement's Messaging: Doom vs Hope
[30:16 - 33:10]
-
Dire Projections Motivated Action:
- Pesca probes whether McKibben and others, by painting a dire picture, motivated the very progress now being witnessed—and whether perhaps the catastrophe was averted because the warnings were heeded.
"Can we say now that as we look back, it was dire if we did something about it, but we did do something about it?" — Mike Pesca [31:00]
-
McKibben on Honesty and Scale:
- McKibben says he always tried to simply “tell the truth about what we know and where we are.”
- The situation is still urgent: “every tenth of a degree” of further warming puts another ~100 million people in danger zones.
- What’s new is having a solution that truly “scales”—renewables can be deployed rapidly and everywhere.
"It's a last hope that we can seize... if we do... we will be able to shave tenths of a degree off how hot the planet gets." — Bill McKibben [32:20]
5. Have We Changed Our Consumption Actually? The Limits of 'Defiant Reflex'
[34:49 - 38:47]
-
Pesca’s Question: Have humans actually overhauled consumption patterns, as McKibben previously advocated, or are we “slowly adopting EVs” while homes, cars, and lifestyles remain expansive?
“I’m going to say if you look at the size of houses in America as one metric, they’re big and getting bigger…” — Mike Pesca [35:09]
-
McKibben’s Response:
- Agrees consumption patterns remain problematic, but the switch to renewables is revolutionary and may enable new, less exploitative forms of society.
- If oil had always been of “trivial value,” many wars, coups, and political dominations would have been avoided.
- Clean energy decentralizes power—“it’s hard to figure out how to fight a war over sunshine.”
“It’s a kind of keystone switch... I’m not sure I’ll live long enough to see it. But it fascinates me with those implications.” — Bill McKibben [38:12]
6. Geoengineering: Last Resort or Dangerous Diversion?
[38:47 - 45:47]
-
Geoengineering Defined: Large-scale scientific interventions in the Earth's climate system (e.g., solar radiation management).
-
Skepticism is Warranted:
- McKibben firmly sees geoengineering as a “terrible idea”—akin to an addict’s escape plans.
- Physical risks (e.g., disrupting monsoons) are huge and unpredictable.
- “If we don’t very quickly embrace [solar and wind] solutions, then... there will be every kind of break-the-glass solution that you can imagine.” [40:17]
-
But All Options May Be Needed—If The World Worsens:
- In extreme catastrophe, nations (e.g., India in Kim Stanley Robinson’s Ministry for the Future) may unilaterally attempt geoengineering out of desperation.
-
Pesca's Technocratic Instinct:
- Would prefer “all hands on deck”—argues for pragmatic experimentation with all solutions alongside values-based approaches.
“I'm more drawn to the amoral technocratic solutions than you are.” — Mike Pesca [44:46]
-
McKibben’s Parting Wisdom:
- “We've got a ticket. We’ve got a golden ticket right now and we should cash it in. That’s our chance right now. And we may not get another one in time that counts.” [45:28]
