You´d be hard put to find a better illustration of the old chestnut about the EMH economist whose friend tells him there´s a banknote lying in the road:
Can't be. If there was a bill on the ground, somebody would have already picked it up.
Where to begin? Most normal people would say: that´s another nail in the already well-sealed coffin of the EMH. But faced with indisputable facts about solar market prices and installation quantities, Cowen´s response is: where´s the solar boom or fossil bust in asset prices? He can´t see one, so the facts must be wrong, or more politely epiphenomenal noise. Note that the objection is not based on any falsifiable hypothesis about solar PV, such as: Germany will have to cancel its solar PV feed-in tariff as unaffordable, silicon feedstock supply will hit a new bottleneck like the one that kept prices from falling in 2004-2008, solar PV will turn out to cause cancer, impotence and obesity or at least will be thought to do so. (Now there´s a hot tip to the oil industry PR men: work up some scares.) For the record, while Germany did reduce its feed-in tariff, China has announced one.
You know, even after two years at Chicago, where like every professor tells you that same joke at least three times every semester, it never gets old, does it?
It's of course perfectly possible that markets are simply not recognizing the danger to fossil fuel stocks, and we are in for a very exciting disruption in the next ten years. (In which case, I am wrong about a carbon tax and other emissions controls; we should just wait eight years.)
On the other hand, it's also possible that people who trade those stocks for a living--some of whom may even be as smart as James Wimberly, have considered this possibility, and don't find it very likely. What might those reasons be?
1) Mindless trend extrapolation is hours of fun for the entire family, but it is incorrect at least as often as it is correct, and possibly more often.
Wimberly uses this graph:
And very possibly prices will keep falling, the way that microchips have. On the other hand, maybe they'll plateau. Wimberly points out that solar panels are fundamentally a manfuacturing business, not a resource business, which is certainly promising . . . but the prices of other manufactured goods that experienced steep declines did not necessarily keep plummeting to zero.
2) Solar panel costs are not the only cost of a solar installation. According to the Energy Bible (which comports roughly with other figures I've seen online), about half the cost, or a little more, of putting in solar panels comes from the cells. The rest comes from the other stuff you need: batteries, transformers, wiring, and labor. As far as I know, the cost of these things is not falling as fast as the cost of solar panels.
Assume that these costs have held relatively steady, with the labor component being the most unstable. Ten years ago, most of the cost of an installation would have been the solar panels. But as those prices decline, the installed cost (without tax incentives) will be increasingly dominated by labor and other materials. Assuming that that graph says what I think it does, that implies that even if cells become free, we'd plateau slightly north of the average electricity price.
3) There's a storage problem. Yes, intriguing things are being done with hot salt and so forth. But how attractive are the costs compared to home installations? What percentage of their total generation costs represent solar cells, versus labor and other things whose prices aren't falling so fast?
Putting the pieces together, our national battery occupies a volume of 4.4 billion cubic meters, equivalent to a cube 1.6 km (one mile) on a side. The size in itself is not a problem: we'd naturally break up the battery and distribute it around the country. This battery would demand 5 trillion kg (5 billion tons) of lead.
A USGS report from 2011 reports 80 million tons (Mt) of lead in known reserves worldwide, with 7 Mt in the U.S. A note in the report indicates that the recent demonstration of lead associated with zinc, silver, and copper deposits places the estimated (undiscovered) lead resources of the world at 1.5 billion tons. That's still not enough to build the battery for the U.S. alone. We could chose to be optimistic and assume that more lead will be identified over time. But let's not ignore completely the fact that at this moment in time time, no one can point to a map of the world and tell you where even 2% of the necessary lead would come from to build a lead-acid battery big enough for the U.S. And even the undiscovered, but suspected lead falls short.
What about cost? At today's price for lead, $2.50/kg, the national battery would cost $13 trillion in lead alone, and perhaps double this to fashion the raw materials into a battery (today's deep cycle batteries retail for four times the cost of the lead within them). But I guarantee that if we really want to use more lead than we presently estimate to exist in deposits, we're not dealing with today's prices. Leaving this caveat aside, the naïve $25 trillion price tag is more than the annual U.S. GDP. Recall that lead-acid is currently the cheapest battery technology. Even if we sacrificed 5% of our GDP to build this battery (would be viewed as a huge sacrifice; nearly a trillion bucks a year), the project would take decades to complete.
But even then, we aren't done: batteries are good for only so many cycles (roughly 1000, depending on depth of discharge), so the national battery would require a rotating service schedule to recycle each part once every 5 years or so. This servicing would be a massive, expensive, and never-ending undertaking.
Moreover, while some sort of battery-replacement would help deal with the base-load problem (solar and wind are more variable than conventional sources, which means they have limited applications), they don't fix the transportation problem. Batteries are heavy and expensive, and as I understand it, absent some fairly radical breakthrough, they won't work at all in aviation; the energy density isn't high enough to permit the plane to take off. They're better for autos, but people don't want the limited range those vehicles currently offer.
4) To really take the market by storm, solar (plus storage) doesn't need to beat the average cost of electricity; it needs to beat the individual cost of each fuel type. DOE seems to think that by 2016 solar is still going to be a lot more expensive per kilowatt hour than other sources:
It's a pretty long haul before they overtake new coal--much less already-existing coal plants, or advanced natural gas.
The most obvious use for solar is as a replacement for expensive peak-load natural gas power (as I understand it, air conditioning causes most of the demand for these plants, so solar would be a nice complement.) But unless it gets massive subsidies, solar (including any storage mechanism you come up with) is going to have to individually defeat each type of electricity plant on price and/or availability, not "the average retail price of electricity"--which already includes some expensive solar and wind power.
Maybe that's possible--though that would still leave transportation to worry about. But that graph doesn't show it.
I'd close by restating Tyler's question in a slightly different way: if the price of solar is really likely to keep falling until it's cheaper than coal, why don't we see this revealed in the behavior of global warming activists? Where are Greens saying "We've decided to move on to more pressing issues, because clearly, the carbon emissions problem is just about solved."
If solar panels really become cheap enough to replace most electric generation, that will be extraordinarily disruptive, in ways that will be both good and bad for the environment. But I'm not seeing a shift away from climate change in order to focus more on, say, sustainable water-use or species conservation. Everyone seems just as worried about climate change as they've ever been, even though such cheap solar panels would render the issue mostly moot.
Revealed preference and market prices certainly can't tell you everything about the future. But they can tell you a lot about what people believe about the future.
Angela Merkel has served formal notice that she will lead the German wandering away from the American alliance.
Seven years after the end of the Second World War, on the 10th of March 1952, the governments of the United States, the United Kingdom, France, and the newly established Federal Republic of Germany received an astounding note from the Soviet Union.
The Soviet Union offered to withdraw the troops that then occupied eastern Germany and to end its rule over the occupied zone. Germany would be reunited under a constitution that allowed the country freedom to choose its own social system. Germany would even be allowed to rebuild its military, and all Germans except those convicted of war crimes would regain their political rights. In return, the Allied troops in western Germany would also be withdrawn—and reunited Germany would be forbidden to join the new NATO alliance.
She lived with us for 56 years. She raised me and my siblings without pay. I was 11, a typical American kid, before I realized who she was.
The ashes filled a black plastic box about the size of a toaster. It weighed three and a half pounds. I put it in a canvas tote bag and packed it in my suitcase this past July for the transpacific flight to Manila. From there I would travel by car to a rural village. When I arrived, I would hand over all that was left of the woman who had spent 56 years as a slave in my family’s household.
A new study finds that people today who eat and exercise the same amount as people 20 years ago are still fatter.
There’s a meme aimed at Millennial catharsis called “Old Economy Steve.” It’s a series of pictures of a late-70s teenager, who presumably is now a middle-aged man, that mocks some of the messages Millennials say they hear from older generations—and shows why they’re deeply janky. Old Economy Steve graduates and gets a job right away. Old Economy Steve “worked his way through college” because tuition was $400. And so forth.
We can now add another one to that list: Old Economy Steve ate at McDonald’s almost every day, and he still somehow had a 32-inch waist.
A study published recently in the journal Obesity Research & Clinical Practice found that it’s harder for adults today to maintain the same weight as those 20 to 30 years ago did, even at the same levels of food intake and exercise.
The condition has long been considered untreatable. Experts can spot it in a child as young as 3 or 4. But a new clinical approach offers hope.
This is a good day, Samantha tells me: 10 on a scale of 10. We’re sitting in a conference room at the San Marcos Treatment Center, just south of Austin, Texas, a space that has witnessed countless difficult conversations between troubled children, their worried parents, and clinical therapists. But today promises unalloyed joy. Samantha’s mother is visiting from Idaho, as she does every six weeks, which means lunch off campus and an excursion to Target. The girl needs supplies: new jeans, yoga pants, nail polish.

At 11, Samantha is just over 5 feet tall and has wavy black hair and a steady gaze. She flashes a smile when I ask about her favorite subject (history), and grimaces when I ask about her least favorite (math). She seems poised and cheerful, a normal preteen. But when we steer into uncomfortable territory—the events that led her to this juvenile-treatment facility nearly 2,000 miles from her family—Samantha hesitates and looks down at her hands. “I wanted the whole world to myself,” she says. “So I made a whole entire book about how to hurt people.”
Should you drink more coffee? Should you take melatonin? Can you train yourself to need less sleep? A physician’s guide to sleep in a stressful age.
During residency, Iworked hospital shifts that could last 36 hours, without sleep, often without breaks of more than a few minutes. Even writing this now, it sounds to me like I’m bragging or laying claim to some fortitude of character. I can’t think of another type of self-injury that might be similarly lauded, except maybe binge drinking. Technically the shifts were 30 hours, the mandatory limit imposed by the Accreditation Council for Graduate Medical Education, but we stayed longer because people kept getting sick. Being a doctor is supposed to be about putting other people’s needs before your own. Our job was to power through.
The shifts usually felt shorter than they were, because they were so hectic. There was always a new patient in the emergency room who needed to be admitted, or a staff member on the eighth floor (which was full of late-stage terminally ill people) who needed me to fill out a death certificate. Sleep deprivation manifested as bouts of anger and despair mixed in with some euphoria, along with other sensations I’ve not had before or since. I remember once sitting with the family of a patient in critical condition, discussing an advance directive—the terms defining what the patient would want done were his heart to stop, which seemed likely to happen at any minute. Would he want to have chest compressions, electrical shocks, a breathing tube? In the middle of this, I had to look straight down at the chart in my lap, because I was laughing. This was the least funny scenario possible. I was experiencing a physical reaction unrelated to anything I knew to be happening in my mind. There is a type of seizure, called a gelastic seizure, during which the seizing person appears to be laughing—but I don’t think that was it. I think it was plain old delirium. It was mortifying, though no one seemed to notice.
As Republicans in Congress try to fend off the flurry of scandals, they are haunted by a question: Is this as good as it’s going to get?
The speaker of the House strode to his lectern on a recent Thursday to confront another totally normal day on Capitol Hill: health care, tax reform, a president under investigation, rumblings of impeachment.
“Morning, everybody!” Paul Ryan chirped. “Busy week!”
It was indeed: Less than a day had passed since the appointment of a special prosecutor to investigate Russia’s involvement in the presidential campaign; just a few hours since President Trump angrily tweeted that the investigation was “the single greatest witch hunt of a politician in American history!”; and only minutes since the Russia-linked former national-security adviser, Michael Flynn, had begun defying congressional subpoenas. A few days prior, the president had been accused of revealing sensitive intelligence information to the Russian foreign minister.
In his new book, Ben Sasse has identified the right project for America: rehabilitating a shared moral language.
In just two short years, Senator Ben Sasse has gone from Capitol Hill newbie to digital president puncher, tweeting about Donald Trump’s affairs and the Midwestern dumpster fires he found more appealing than 2016’s Oval Office contenders.
Yet, on his breaks from Twitter, Sasse managed to craft a serious new book, The Vanishing American Adult. It advances a thesis that’s at once out of place at this political moment and almost too on-the-nose for the Trump years: He believes Americans have lost their sense of personal integrity and discipline. For the country to deal with the troubles ahead—including automation, political disengagement, and the rise of nativist, huckster politicians, he says—people must recover their sense of virtue. The republic depends on it.
Facing reported financial problems and allegations of abuse, the once-bankable star now seems stuck in franchise hell with no obvious exit.
When Johnny Depp sailed onscreen in 2003’s Pirates of the Caribbean: The Curse of the Black Pearl as Captain Jack Sparrow (to this day, a memorable superhero entrance), it was his first-ever appearance in a summer blockbuster. He’d been in surprise wintertime hits (Edward Scissorhands, Sleepy Hollow), well-regarded Oscar players (Donnie Brasco, Chocolat), and, of course, many a cult classic (Fear and Loathing in Las Vegas, Ed Wood). But the idea of Depp headlining a big-budget, mainstream franchise film was alarming enough to Disney’s then-studio head Michael Eisner that he protested, on seeing early footage, that Depp was “ruining the movie!”
Fourteen years later, Disney is serving up a fifth Pirates of the Caribbean, this time subtitled Dead Men Tell No Tales, budgeted at a cool $230 million. Since bursting into international superstardom with the first Pirates, Depp has become increasingly reliant on mega-budgeted action films and broad comedies. At the same time, his public profile has collapsed after his now ex-wife Amber Heard accused him of domestic violence during their divorce, and stories emerged of the mega-budgeted lifestyle that had somehow mired Depp in deep financial trouble despite his movie earnings.
It’s known as a modern-day hub of progressivism, but its past is one of exclusion.
PORTLAND, Ore.— Victor Pierce has worked on the assembly line of a Daimler Trucks North America plant here since 1994. But he says that in recent years he’s experienced things that seem straight out of another time. White co-workers have challenged him to fights, mounted “hangman’s nooses” around the factory, referred to him as “boy” on a daily basis, sabotaged his work station by hiding his tools, carved swastikas in the bathroom, and written the word “nigger” on walls in the factory, according to allegations filed in a complaint to the Multnomah County Circuit Court in February of 2015.
Pierce is one of six African Americans working in the Portland plant whom the lawyer Mark Morrell is representing in a series of lawsuits against Daimler Trucks North America. The cases have been combined and a trial is scheduled for January of 2017.
Some firm handshakes, forced smiles, and awkward sword dances. In short, nothing.
Let’s hear it for the Rainbow Tour It’s been an incredible success
We weren’t quite sure, we had a few doubts
Will Evita win through?
But the answer is yes
There you are, I told you so
Makes no difference where she goes
The whole world over just the same
Just listen to them call her name
And who would underestimate the actress now?
—Andrew Lloyd Webber and Tim Rice, Evita
Like Donald Trump, Juan and Eva Perón were populists. They seem to have shared Trump’s understanding of the purposes of philanthropy (for more, read up about the Eva Perón Foundation) and the importance of fiscal probity. And like Eva in 1947, Donald Trump has just completed a glitzy overseas trip.
It had ample farcical episodes: the Saudi king, the dictator of Egypt, and the president of the United States placing their hands on a glowing orb that evoked for some a lampoon of Lord of the Rings. The secretary of state assuring us that no one overseas was paying attention to Trump’s domestic troubles (palpably, indeed laughably, untrue) even as his spokesman excluded the American press from a briefing attended by the considerably more docile reporters of the Kingdom of Saudi Arabia. The national-security adviser insisting, “The entire trip is about human rights, about all civilized people coming together to fight the hatred”—an odd remark to make in a country that lops the hands off thieves and the heads off apostates. The commerce secretary, in one of his more witlessly thuggish remarks, observing complacently about urban Riyadh: “There was not a single hint of a protester anywhere there during the whole time we were there.” And then there were the video clips: Melania flicking away her husband’s groping hand and the Leader of the Free World giving the prime minister of little Montenegro a good hard shove.
