McKibben is one of our preeminent climate writers and activists, noteworthy for his informed and brilliant explanations of the technical limits - and possibilities - of various climate interventions, and for his lifelong organizing work.
*Here Comes the Sun* is a capstone on several years' worth of surprising, infuriating and inspiring newsletter articles, particularly about the unheralded, unanticipated, and un*believable* growth of solar.

Everything else might be utterly *fucked*, but solar is going *great.*
In McKibben's telling, everything about solar is going better than anticipated. Solar efficiency is increasing *exponentially* with prices falling through the floor. The material bill for solar is also in freefall. Everything surrounding solar is going amazing, too.

Battery capacity is improving even faster than solar generation, and the best new batteries use the incredibly abundant element sodium (not lithium) to store those useful electrons. Long-haul transmission lines are crisscrossing the world.
Hyper-reliable electric cars keep getting cheaper, and the batteries are lasting *much* longer than we used to think they would.

Some of these vehicles are nigh-miraculous, from the ebikes that get 5 miles to the *penny*, to the world's heaviest EV, a dump truck that shuttles to a quarry atop a hill where it is loaded with rocks, then regeneratively brakes its way back *down* the hill, accumulating enough charge to get back up to the top again (a perpetual motion machine!).

Heat pumps and induction tops are actually more efficient than burning natural gas - in other words, it's cheaper to convert sunshine into electrons and electrons into heat than it is to just burn gas:

Then there's the capacity. China's solar capacity growth is *insane* - the solar equivalent of a new coal plant is coming online *every eight hours*.

But it's even more intense in poor regions of the global south, like in Pakistan, where a legion of installers have learned their craft from Tiktok videos set to songs from popular musical films, leading to one of the most rapid electrification rollouts in human history.

The closer a country is to the equator, the more sense solar makes, of course, so solar is sweeping some of the poorest countries in the world, liberating them from the need to attract foreign currency they can use to buy dollar-denominated barrels of oil.
Everything we thought would be a solar bottleneck turns out to be a feature, not a bug. Perhaps you've heard that solar is unsustainable because it competes for agricultural land, making starvation the price of clean energy.

Wrong: solar provides shade for many crops that have been withering in the soaring heat of a climate-wracked world, and limits evaporation, reducing the amount of water needed to produce food crops. What's more, the cooling effect of that soil-retained moisture helps keep the shade-providing solar panels within their optimal operating temperature, increasing the efficiency of their power generation.

And of course, every time someone switches from hydrocarbon fuels to solar, they reduce the demand for ethanol, and a third of America's corn goes into making this stupid, wasteful fuel additive (and corn is America's most prolific crop). That's land that can be given over to growing useful food crops. Solar is *increasing* our agricultural yields, not competing for farmland.

Then there's the material bill for solar: a recurring (and legitimate, and worthwhile) concern about electrification is that it comes with a vast material bill that will necessitate massive extraction projects. There's good reason to worry that the copper, lithium and conflict minerals needed for planetary solarization will come at the expense of the despoilation of habitat, the poisoning of indigenous people, and the ruination of miners.

Happily, this, too is turning out to be a tractable problem. First off, because the material bill for solarization just isn't that big when compared to the amount of *fossil fuels* we consume every year. To create the batteries we need to keep the whole *world's* lights on when the sun goes down and the wind stops blowing, we will need to extract *one seventeenth* of the amount of minerals we burn *every year* in the fossil fuel system:

And while some of those materials will have to be replaced - necessitating more extraction - most of them can be recycled. The biggest bottleneck in recycling complex manufactured products like batteries is that it's energy intensive, but solar makes energy *cheap*.

The last time I spoke with Deb, she waxed lyrical about how all that too-cheap-to-meter energy will make it possible to recover materials from old energy systems that weren't designed to be broken down and re-integrated into the material stream at their end-of-life, and how it will also allow us to economically make *new* devices that *are* designed to be broken down and re-used when their duty-cycles end.

There's nothing about renewables that cuts against the aesthetics or values of the conservative movement. Generating your own power on the roof of your own homestead (or with a clip-on panel attached to your apartment balcony) is fully compatible with the ideal of a sovereign individual, not beholden to a government-regulated power monopoly.

Solar also fits neatly within the idea of Christian Dominionism, that "God gave man all the things of the Earth." An existence dependent on setting fire to a dwindling supply of critters that died millions of years ago leaves a *lot* of value on the table. If God wants us to breed chickens to have vast drumsticks and breasts, why wouldn't He want us to capture the hyperabundant sunshine He sends our way every morning at dawn?

Why would we limit ourselves to this inefficient, inconvenient and expensive ancient garbage?
What's more, solar is *cheap* - over the past year, we've crossed a threshold, and solar is now *substantially* cheaper than coal, natural gas or oil. It's getting cheaper still, with no bottom in sight. No wonder solar deployment is growing exponentially.

The whole point of an extraction economy is to control a key factor of production so that other people need to come to you in order to do everything else. The ideal oil economy consists of a series of holes in the ground surrounded by people with guns, owned by a cartel that chokes off supply to maximize profits while leaving a highly visible share of the world's population shivering in the dark as a warning to anyone complaining about their prices.

Fossil fuels are valuable because they are a *chokepoint* on the entire productive economy.

I think there's a collision looming between these rent-seeking missiles and the ever-cheaper, ever-better solar world. Eventually, these garbage people will stop trying to halt renewables, and they'll start looking to *own* them.
You can already see the first stirrings of this: the more daring carbon barons are starting to flirt with geothermal and nuclear, and they're awfully fond of hydroelectric.

Whatever the merits or demerits of these technologies, they have the (dubious) advantage that they are amenable to rent-extraction. To put up a dam, you need to own the land around the river. To run a nuke, you need to own a uranium mine.
Even geothermal is ineluctably place-based: there are lots of places where a borehole will hit something hot and bubbly, but it's an expensive proposition with a big, fat capital moat that limits competition.

in reply to Cory Doctorow • • •On a related note, recently thanks to wind power, Alberta (Canada's Texas) has had "free power".
pipelineonline.ca/alberta-had-…
The wind was so strong and steady that wind turbines supplied all the energy needed. The entire province's electricity demands could be met by power producers who were willing to accept $0 for the power they put on the grid. (The article explains how that can happen.)
This is despite Alberta having a right-wing government that abruptly stopped approving renewable projects in 2023.
If we can get to a point where energy is cheap, and sometimes even free, it could have huge consequences.
Alberta had free power for more than a day in August, and seven hours last weekend – how does that happen?
