Human history is something like 200,000 years old, which means we’ve had a lot of time to come up with really bad ideas.
Bloodletting. “Dynamic ticket pricing.” Invading Russia in the winter. The McLobster. You get the picture; they’ve not all been winners.
Around the turn of the 2010s, another brilliant-at-the-time idea popped into our disproportionally large prefrontal cortexes. Maybe, this niggling went, the cavemen actually had it better than we do?
This idea — which, if you consider it for more than 10 seconds, is obviously wrong, since cavemen lived in a world that had sabertooth tigers but not microwaves and walk-in urgent cares — nevertheless took off. The “Paleo diet” exploded in popularity. Fitness bros started doing Crossfit and other strength-centric ancestral exercises and overenthusiastically donated their blood to mimic the acquisition of Stone Age wounds. Being a nice parent got rebranded, favorably, as “caveman parenting.” Kevin Roose wrote an entire piece about the benefits of pooping like a caveman. These were dark times.
Fads come and go, and we’ve mostly course corrected since then. Yuval Noah Harari, whose 2014 bestseller Sapiens made him a superstar and contributed to the belief that Stone Ages humans were happier, has since been taken down a notch by fact-checkers. The Crossfit guy got canceled, high-intensity interval training is out, and “sculpt” — not a word one usually associates with cavemen — is in. We’ve at last decided that toe-shoes, meant to get us closer to our barefoot ancestors, are “stupid” and must be stopped.
Some vestiges of Stone Age mania remain, though many of the trends have moderated and become more reasonable. The Paleo diet peaked in 2013, but it’s not gone completely away; there is renewed interest, as one would expect, every January. Still, much of the diet’s foundational science — that we need to eat the foods our bodies were “optimized” to eat during the Stone Age, before the evils wrought by the agricultural revolution and its diabolical offspring: processed sugars and carbohydrates — has been debunked.
Eating whole and sustainable foods, though, isn’t going away. The “pegan diet” (from “Paleo” and “vegan”) is “like the Paleo diet,” one dietitian nutritionist has explained, in that it focuses on foods that “early humans would have hunted or gathered. But the twist is that most of your daily food intake will be plants.” Many researchers say this is the more accurate ancient diet anyway, not to mention far better for the planet. You don’t even need to justify the meal plan by saying our Neolithic forefathers did it: It’s a good idea because it’s a smart and ethical way of eating to address problems that exist in our modern world.
The extreme, macho deprivations of the early 2010s caveman trend have also had their edges sanded off. Interest in “living off the grid” has fallen since its 2013/2014 highs, but the comparatively comfy “van life” has slowly grown. People still crave an escape from the blinking, beeping demands of modern life — there is currently an 18-month-long waitlist to be shut in a completely dark, scantly furnished room in Oregon with no TV or phone, and it costs $250 a night — but that has more to do with the anxieties and demands of contemporary life than misplaced beliefs about the superiority of cavemen living. Unplugging every now and then is a good thing, even at its most literal, but not specifically because it makes us more like Ötzi the Iceman.
It seems clear in retrospect why we wanted so badly to live like cavemen: Modern life is hard. There's consumption fatigue that comes from having 62 different Oreo varieties on the shelf in the grocery store and we want someone to take over decision-making (even if that decision required an at-home meat locker). We are so time-pressed that a scientific blessing for quick workouts and winging-it parenting is very enticing. We may also sense that nature is in peril and so we long for the days when we hadn't destroyed so much of it. Every generation yearns for a “better, simpler time" but, as Gillian Osbourne at The New Inquirywrote back in 2014, "our gazing at the oil wars and rising sea levels of today have provoked collective sighs for deep, and distant, ecological histories."
Of course, while the caveman lifestyle may have spoken to real needs, it was impossibly, laughably selective in picking what it elevated to importance. We were supposed to eat like cavemen because our bodies are genetically similar to early humans’ but no one proposed treating infections with Stone Age first-aid, even if the same principle applied.
With a healthy perspective and accurate science, ancient ways of living can still be productive sources of inspiration. But let’s not bring everything back. Because you know what else is technically an ancient and natural idea? Cannibalism.

On the presidential debate, California’s wildfires, and the nuclear workforce
Current conditions: Hurricane Francine is approaching Louisiana as a Category 1 storm • The streets of Vietnam’s capital of Hanoi are flooded after Typhoon Yagi, and the death toll has reached 143 • Residents of Nigeria’s northern Borno state are urged to watch out for crocodiles and snakes that escaped from a zoo due to flooding.
Former President Trump and Vice President Kamala Harris squared off on the debate stage in Philadelphia last night. Here are some important climate and energy highlights from the evening:
Three large wildfires – the Line fire, the Bridge fire, and the Airport fire – are burning in Southern California, fueled by intense heat and thick, dry vegetation. Already more than 100,000 acres have been scorched. The Line fire is closing in on the popular vacation destination Big Bear, and is threatening some 65,000 structures. Los Angeles County Fire Chief Anthony Marrone said the scale of the emergencies is straining firefighting resources, and FEMA is sending financial aid to the state. In neighboring Nevada, the Davis Fire has grown to nearly 6,000 acres and is burning toward ski resorts in Tahoe. Temperatures in the region started to cool yesterday after a long and brutal heat wave. The weather shift could help firefighters bring the blazes under control.
The White House is launching an American Climate Corps national tour this fall to highlight the work being carried out by corps members in different communities and showcase important projects. The events will feature remarks from the administration and other officials, roundtable talks with ACC members, and swearing-in ceremonies. The tour began in Maine this week with a focus on climate resilience and urban forestry, and heads to Arizona next week. The rest of the schedule is as follows, with more dates to come:
The number of students studying to become nuclear engineers is declining as demand for carbon-free nuclear energy is on the rise, according toThe Wall Street Journal. Citing data from the Oak Ridge Institute for Science and Education, the Journal reported that just 454 students in the U.S. graduated with a degree in the field in 2022, down 25% from a decade earlier. Meanwhile, the industry’s workforce is aging. “We need nuclear expertise in order to combat climate change,” said Sara Pozzi, professor of nuclear engineering and radiological sciences at the University of Michigan. “We are at a crucial point where we need to produce the new generation of nuclear experts so that they can work with the older generation and learn from them.” The drop in new recruits comes down to nuclear’s image problem thanks to public disasters like Chernobyl and Fukushima, the Journal speculated.
Critical metal refining company Nth Cycle announced this week it has become the first company to produce nickel and cobalt mixed hydroxide precipitate (MHP) in the U.S. following the opening of its commercial-scale facility in Ohio. The company’s “Oyster” technology uses electricity to turn recyclable industrial scrap and mined ore into MHP, a key component in clean-energy technologies like batteries. “This revolutionary innovation replaces pyrometallurgy with one of the cleanest technologies in the world, and accelerates the net zero targets of the public and private sector,” the company said in a press release. It claims the Ohio unit can produce 900 metric tons of MHP per year, which would be enough to supply batteries for 22 million cell phones. The company says its process reduces emissions by 90% compared to traditional mining methods and can help EV manufacturers meet the IRA’s sourcing requirements.
A new nationwide poll of 1,000 registered U.S. voters found that 90% of respondents support President Biden’s federal clean energy incentives in the Inflation Reduction Act, including 78% of respondents who said they were Trump voters.
Maybe you’ve never heard of it. Maybe you know it too well. But to a certain type of clean energy wonk, it amounts to perhaps the three most dreaded words in climate policy: the interconnection queue.
The queue is the process by which utilities decide which wind and solar farms get to hook up to the power grid in the United States. Across much of the country, it has become so badly broken and clogged that it can take more than a decade for a given project to navigate.
On this week’s episode of Shift Key, Jesse and Rob speak with two experts about how to understand — and how to fix — what is perhaps the biggest obstacle to deploying more renewables on the U.S. power grid. Tyler Norris is a doctoral student at Duke University’s Nicholas School of the Environment. He was formerly vice president of development at Cypress Creek Renewables, and he served on North Carolina Governor Roy Cooper’s Carbon Policy Working Group. Claire Wayner is a senior associate at RMI’s carbon-free electricity program, where she works on the clean and competitive grids team. Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University.

Here is an excerpt from our conversation:
Robinson Meyer: Can I interject and just ask why, over the past decade, the interconnection queue got much longer — but also over the past decade, 15 years, the U.S. grid did change in character and in fuel type a lot, right? We went from burning a lot of coal to a lot of natural gas. And that transition is often cited as one of the model transitions, one of the few energy transitions to happen globally that happened at the speed with which we would need to decarbonize. Obviously, switching coal to gas is not decarbonizing, but it is a model — it happened fast enough that it is a good model for what decarbonizing would look like in order to meet climate goals.
Evidently, that did not run into these kind of same interconnection queue problems. Why is that? Is that because we were swapping in within individual power plants? We were just changing the furnace from a coal furnace to a gas furnace? Is that because these were larger projects and so it didn’t back up in the queue in the same way that a lot of smaller solar or wind farms do?
Claire Wayner: I would say all the reasons you just gave are valid, yeah. The coal to gas transition involved, likely, a lot of similar geographic locations. With wind and solar, we’re seeing them wanting to build on the grid and in a lot of cases in new, rather remote locations that are going to require new types of grid upgrades that the coal to gas transition just doesn’t have.
Jesse Jenkins: Maybe it is — to use a metaphor here — it’s a little bit like traffic congestion. If you add a generator to the grid, it’s trying to ship its power through the grid, and that decision to add your power mix to the grid combines with everyone else that’s also generating and consuming power to drive traffic jams or congestion in different parts of the grid, just like your decision to hop in the car and drive to work or to go into the city for the weekend to see a show or whatever you’re doing. It’s not just your decision. It’s everyone’s combined decisions that affects travel times on the grid.
Now, the big difference between the grid and travel on roads or most other forms of networks we’re used to is that you don’t get to choose which path to go down. If you’re sending electricity to the grid, electricity flows with physics down the path of least resistance or impedance, which is the alternating current equivalent of resistance. And so it’s a lot more like rivers flowing downhill from gravity, right? You don’t get to choose which branch of the river you go down. It’s just, you know, gravity will take you. And so you adding your power flows to the grid creates complicated flows based on the physics of this mesh network that spans a continent and interacts with everyone else on the grid.
And so when you’re going from probably a few dozen large natural gas generators added that operate very similarly to the plants that they’re replacing to hundreds of gigawatts across thousands of projects scattered all over the grid with very complicated generation profiles because they’re weather-dependent renewables, it’s just a completely different challenge for the utilities.
So the process that the regional grid operators developed in the 2000s, when they were restructuring and taking over that role of regional grid operator, it’s just not fit for purpose at all for what we face today. And I want to highlight another thing you mentioned, which is the software piece of it, too. These processes, they are using software and corporate processes that were also developed 10 or 20 years ago. And we all know that software and computing techniques have gotten quite a bit better over a decade or two. And rarely have utilities and grid operators really kept pace with those capabilities.
Wayner: Can I just say, I’ve heard that in some regions, interconnection consists of still sending back and forth Excel files. To Tyler’s point earlier that we only just now are getting data on the interconnection queue nationwide and how it stands, that’s one challenge that developers are facing is a lack of data transparency and rapid processing from the transmission providers and the grid operators.
And so, to use an analogy that my colleague Sarah Toth uses a lot, which I really love: Imagine if we had a Domino’s pizza tracker for the interconnection queue, and that developers could just log on and see how their projects are doing in many, if not most regions. They don’t even have that visibility. They don’t know when their pizza is going to get delivered, or if it’s in the oven.

In the closing minutes of the first presidential debate tonight, Donald Trump’s attacks on Kamala Harris took an odd, highly specific, and highly Teutonic turn. It might not have made sense to many viewers, but it fit into the overall debate’s unusually substantive focus on energy policy.
“You believe in things that the American people don’t believe in,” he said, addressing Harris. “You believe in things like, we’re not gonna frack. We’re not gonna take fossil fuel. We’re not gonna do — things that are going to make this country strong, whether you like it or not.”
“Germany tried that and within one year, they were back to building normal energy plants,” he continued. “We’re not ready for it.”
What is he talking about? Let’s start by stipulating that Harris has renounced her previous support for banning fracking. During the debate, she bragged that the United States has hit an all-time high for oil and gas production during her vice presidency.
But why bring Germany into it? At the risk of sane-washing the former president, Trump appears to be referencing what German politicians call the Energiewiende, or energy turnaround. Since 2010, Germany has sought to transition from its largest historic energy sources, including coal and nuclear energy, to renewables and hydropower.
The Energiewiende is often discussed inside and outside of Germany as a climate policy, and it has helped achieve global climate goals by, say, helping to push down the global price of solar panels. But as an observant reader might have already noticed, its goals are not entirely emissions-related: Its leaders have also hoped to use the Energiewiende to phase out nuclear power, which is unpopular in Germany but which does not produce carbon emissions.
The transition has accomplished some of its goals: The country says that it is on target to meet its 2030 climate targets. But it ran into trouble after Russia invaded Ukraine, because Germany obtained more than half of its natural gas, and much of its oil and coal besides, from Russia. Germany turned back on some of its nuclear plants — it has since shut them off again — and increased its coal consumption. It also began importing fossil fuels from other countries.
In order to shore up its energy supply, Germany is also planning to build 10 gigawatts of new natural gas plants by 2030, although it says that these facilities will be “hydrogen ready,” meaning that they could theoretically run on the zero-carbon fuel hydrogen. German automakers, who have lagged at building electric vehicles, have also pushed for policies that support “e-fuels,” or low-carbon liquid fuels. These fuels would — again, theoretically — allow German firms to keep building internal combustion engines.
So perhaps that’s not exactly what Trump said, to put it mildly — but it is true that to cope with the Ukraine war and the loss of nuclear power, Germany has had to fall back on fossil fuels. Of course, at the same time, more than 30% of German electricity now comes from wind and solar energy. In other words, in Germany, renewables are just another kind of “normal energy plant.”
