"It is 70 years since AT&T’s Bell Labs unveiled a new technology for turning sunlight into power. The phone company hoped it could replace the batteries that run equipment in out-of-the-way places. It also realised that powering devices with light alone showed how science could make the future seem wonderful; hence a press event at which sunshine kept a toy Ferris wheel spinning round and round.

Today solar power is long past the toy phase. Panels now occupy an area around half that of Wales, and this year they will provide the world with about 6% of its electricity—which is almost three times as much electrical energy as America consumed back in 1954. Yet this historic growth is only the second-most-remarkable thing about the rise of solar power. The most remarkable is that it is nowhere near over.

To call solar power’s rise exponential is not hyperbole, but a statement of fact. Installed solar capacity doubles roughly every three years, and so grows ten-fold each decade. Such sustained growth is seldom seen in anything that matters. That makes it hard for people to get their heads round what is going on. When it was a tenth of its current size ten years ago, solar power was still seen as marginal even by experts who knew how fast it had grown. The next ten-fold increase will be equivalent to multiplying the world’s entire fleet of nuclear reactors by eight in less than the time it typically takes to build just a single one of them.

Solar cells will in all likelihood be the single biggest source of electrical power on the planet by the mid 2030s. By the 2040s they may be the largest source not just of electricity but of all energy. On current trends, the all-in cost of the electricity they produce promises to be less than half as expensive as the cheapest available today. This will not stop climate change, but could slow it a lot faster. Much of the world—including Africa, where 600m people still cannot light their homes—will begin to feel energy-rich. That feeling will be a new and transformational one for humankind.

To grasp that this is not some environmentalist fever dream, consider solar economics. As the cumulative production of a manufactured good increases, costs go down. As costs go down, demand goes up. As demand goes up, production increases—and costs go down further. This cannot go on for ever; production, demand or both always become constrained. In earlier energy transitions—from wood to coal, coal to oil or oil to gas—the efficiency of extraction grew, but it was eventually offset by the cost of finding ever more fuel.

As our essay this week explains, solar power faces no such constraint. The resources needed to produce solar cells and plant them on solar farms are silicon-rich sand, sunny places and human ingenuity, all three of which are abundant. Making cells also takes energy, but solar power is fast making that abundant, too. As for demand, it is both huge and elastic—if you make electricity cheaper, people will find uses for it. The result is that, in contrast to earlier energy sources, solar power has routinely become cheaper and will continue to do so.

Other constraints do exist. Given people’s proclivity for living outside daylight hours, solar power needs to be complemented with storage and supplemented by other technologies. Heavy industry and aviation and freight have been hard to electrify. Fortunately, these problems may be solved as batteries and fuels created by electrolysis gradually become cheaper...

The aim should be for the virtuous circle of solar-power production to turn as fast as possible. That is because it offers the prize of cheaper energy. The benefits start with a boost to productivity. Anything that people use energy for today will cost less—and that includes pretty much everything. Then come the things cheap energy will make possible. People who could never afford to will start lighting their houses or driving a car. Cheap energy can purify water, and even desalinate it. It can drive the hungry machinery of artificial intelligence. It can make billions of homes and offices more bearable in summers that will, for decades to come, be getting hotter.

But it is the things that nobody has yet thought of that will be most consequential. In its radical abundance, cheaper energy will free the imagination, setting tiny Ferris wheels of the mind spinning with excitement and new possibilities.

This week marks the summer solstice in the northern hemisphere. The Sun rising to its highest point in the sky will in decades to come shine down on a world where nobody need go without the blessings of electricity and where the access to energy invigorates all those it touches."

oh my god some of my work involves energy efficiency (i.e., finding ways to use less energy to do the same stuff) and electrification (i.e., taking appliances that run on fossil fuels like gas heaters and switching them out for electric ones that can run on solar power etc when available), and it is so maddening to me how often the conversation ends with "we just need to educate consumers, the public really needs education"

no! incorrect!! education lets you off the hook and makes it laypeople's responsibility to research and hold all this confusing-ass conflicting information on top of all their other shit! that is not realistic!!! the public needs you to make this SO EASY THEY CANNOT FUCK IT UP

people are busy! I do this professionally and it is a fuckign nightmare labyrinth quagmire trying to get rebates and whatnot for my own fucking house! MAKE IT EASIER, PEOPLE ARE BUSY AND HAVE THEIR OWN CONCERNS, MAKE IT FUCKING EASY

An end to the climate emergency is in our grasp

On June 20, I'm keynoting the LOCUS AWARDS in OAKLAND.

The problem with good news in the real world is that it's messy. Neat happy endings are for novels, not the real world, and that goes double for the climate emergency. But even though good climate news is complicated and nuanced, that doesn't mean it shouldn't buoy our spirits and fill our hearts with hope.

The big climate news this past week is the National Oceanic and Atmospheric Administration's clarion call about surging CO2 levels – the highest ever – amid a year that is on track to have the largest and most extreme series of weather events in human history:

https://www.noaa.gov/news-release/during-year-of-extremes-carbon-dioxide-levels-surge-faster-than-ever

This is genuinely alarming and you – like me – have probably experienced it as a kind of increase in your background radiation of climate anxiety. Perhaps you – like me – even experienced some acute, sit-bolt-upright-in-bed-at-2AM anxiety as a result. That's totally justifiable. This is very real, very bad news.

And yet…

The news isn't all bad, and even this terrible dispatch from the NOAA is best understood in context, which Bill McKibben provides in his latest newsletter post, "What You Want is an S Curve":

https://billmckibben.substack.com/p/what-you-want-is-an-s-curve

Financier and their critics should all be familiar with Stein's Law: "anything that can't go on forever will eventually stop." This is true outside of finance as well. One of the reasons that we're seeing such autophagic panic from the tech companies is that their period of explosive growth is at an end.

For years, they told themselves that they were experiencing double-digit annual growth because they were "creating value" and "innovating" but the majority of their growth was just a side-effect of the growth of the internet itself. When hundreds of millions of people get online every year, the dominant online services will, on average, gain hundreds of millions of new users.

But when you run out of people who don't have internet access, your growth is going to slow. How can it not? Indeed, at that point, the only ways to grow are to either poach users from your rivals (through the very expensive tactics of massive advertising and sales-support investments, on top of discounts and freebies as switching enticements), or to squeeze your own users for more.

That's why the number of laptops sold in America slowed down. It's why the number of cellphones sold in America slowed down. It's why the number of "smart home" gizmos slowed down.

Even the steepest hockey-stick-shaped exponential growth curve eventually levels off and becomes an S-curve, because anything that can't go on forever will eventually stop.

One way or another, the world's carbon emissions will eventually level off. Even if we drive ourselves to (or over) the brink of extinction and set up the conditions for wildfires that release all the carbon stored in all the Earth's plants, the amount of carbon we pump into the atmosphere has to level off.

Rendering the Earth incapable of sustaining human civilization (or life) is the ultimate carbon reduction method – but it's not my first choice.

That's where McKibben's latest newsletter comes in. He cites a new report from the Rocky Mountain Institute, which shows a major reversal in our energy sources, a shift that will see our energy primarily provided by renewables, with minimal dependence on fossil fuels:

https://rmi.org/insight/the-cleantech-revolution/

The RMI team says that in this year or next, we'll have hit peak demand for fossil fuels (a fact that is consistent with NOAA's finding that we're emitting more CO2 than ever). The reason for this is that so much renewable energy is about to come online, and it is so goddamned cheap, that we are about to undergo a huge shift in our energy consumption patterns.

This past decade saw a 12-fold increase in solar capacity, a 180-fold increase in battery storage, and a 100-fold increase in EV sales. China is leading the world in a cleantech transition, with the EU in close second. Cleantech is surging in places where energy demand is also still growing, like India and Vietnam. Fossil fuel use has already peaked in Thailand, South Africa and every country in Latin America.

We're on the verge of solar constituting an absolute majority of all the world's energy generation. This year, batteries will overtake pumped hydro for energy storage. Every cleantech metric is growing the way that fossil fuels did in previous centuries: investment, patents, energy density, wind turbine rotor size. The price of solar is on track to halve (again) in the next decade.

In short, cleantech growth looks like the growth of other technologies that were once rarities and then became ubiquitous overnight: TV, cellphones, etc. That growth isn't merely being driven by the urgency of the climate emergency: it's primarily a factor of how fucking great cleantech is:

https://rmi.org/wp-content/uploads/2024/05/the_incredible_inefficiency_of_fossils.pdf

Fossil fuels suck. It's not just that they wreck the planet, or that their extraction is both politically and environmentally disastrous. They just aren't a good way to make energy. About a third of fossil fuel energy is wasted in production and transportation. A third! Another third is wasted turning fossil fuels into energy. Two thirds! The net energy efficiency of fossil fuels is about 37%.

Compare that with cleantech. EVs convert electricity to movement with 80-90% efficiency. Heat pumps are 300% efficient (the main fuel for your heat pump is the heat in the atmosphere, not the electricity it draws).

Cleantech is just getting started – it's still in the hockey-stick phase. That means those efficiency numbers are only going up. Rivian just figured out how to remove 1.6 miles of copper wire from each vehicle. That's just one rev – there's doubtless lots of room for more redesigns that will further dematerialize EVs:

https://insideevs.com/news/722265/rivian-r1s-r1t-wiring/

As McKibben points out, there's been a lot of justifiable concern that electrification will eventually use up all our available copper, but copper demand has remained flat even as electrification has soared – and this is why. We keep figuring out new ways to electrify with fewer materials:

https://www.chemanalyst.com/NewsAndDeals/NewsDetails/copper-wire-price-remains-stable-amidst-surplus-supply-and-expanding-mining-25416#:~:text=Global%20Copper%20wire%20Price%20Remains%20Stable%20Amidst%20Surplus%20Supply%20and%20Expanding%20Mining%20Activities

This is exactly what happened with previous iterations of tech. The material, energy and labor budgets of cars, buildings, furniture, etc all fell precipitously every time there was a new technique for manufacturing them. Renewables are at the start of that process. There's going to be a lot of this dematerialization in cleantech. Calculating the bill of materials for a planetary energy transition isn't a matter of multiplying the materials in current tech by the amount of new systems we'll need – as we create those new systems, we will constantly whittle down their materials.

What's more, global instability drives cleantech uptake. The Russian invasion of Ukraine caused a surge in European renewables. The story that energy prices are rising due to renewables (or carbon taxes) is a total lie. Fossil fuels are getting much more expensive, thanks to both war and rampant, illegal price-fixing:

https://www.thebignewsletter.com/p/an-oil-price-fixing-conspiracy-caused

If not for renewables, the incredible energy shocks of the recent years would be far more severe.

The renewables story is very good and it should bring you some comfort. But as McKibben points out, it's still not enough – yet. The examples of rapid tech uptake had big business on their side. America's living rooms filled with TV because America's largest businesses pulled out all the stops to convince everyone to buy a TV. By contrast, today's largest businesses – banks, oil companies and car companies – are working around the clock to stop cleantech adoption.

We're on track to double our use of renewables before the decade is over. But to hold to the (already recklessly high) targets from the Paris Accord, we need to triple our renewables usage. As McKibben says, the difference between doubling and tripling our renewables by 2030 is the difference between "survivable trouble" and something much scarier.

The US is experiencing a welcome surge in utility scale solar, but residential solar is stalling out as governments withdraw subsidies or even begin policies that actively restrict rooftop solar:

https://twitter.com/curious_founder/status/1798049929082097842?s=51

McKibben says the difference between where we are now and bringing back the push for home solar generation is the difference between "fast" and "faster" – that is the difference between tripling renewables by 2030 (survivable) and doubling (eek).

Capitalism stans who argue that we can survive the climate emergency with market tools will point to the good news on renewable and say that the market is the only way to transition to renewables. It's true that market forces are partly responsible for this fast transition. But the market is also the barrier to a faster (and thus survivable) transition. The oil companies, the banks who are so invested in fossil fuels, the petrostates who distort the world's politics – they're why we're not much farther along.

The climate emergency was never going to be neatly solved. We weren't going to get a neat novelistic climax that saw our problems sorted out in a single fell swoop. We're going to be fighting all the way to net zero, and after that, we'll still have decades of climate debt to pay down: fires, floods, habitat loss, zoonotic plagues, refugee crises.

But we should take our wins. Even if we're far from where we need to be on renewables, we're much farther along on renewables than we had any business hoping for, just a few years ago. The momentum is on our side. It's up to us to use that momentum and grow it. We're riding the hockey-stick, they're on that long, flat, static top of the S-curve. Their curve is leveling off and will start falling, ours will grow like crazy for the rest of our lives.
