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.
A child psychologist argues punishment is a waste of time when trying to eliminate problem behavior. Try this instead.
Say you have a problem child. If it’s a toddler, maybe he smacks his siblings. Or she refuses to put on her shoes as the clock ticks down to your morning meeting at work. If it’s a teenager, maybe he peppers you with obscenities during your all-too-frequent arguments. The answer is to punish them, right?
Not so, says Alan Kazdin, director of the Yale Parenting Center. Punishment might make you feel better, but it won’t change the kid’s behavior. Instead, he advocates for a radical technique in which parents positively reinforce the behavior they do want to see until the negative behavior eventually goes away.
As I was reporting my recent series about child abuse, I came to realize that parents fall roughly into three categories. There’s a small number who seem intuitively to do everything perfectly: Moms and dads with chore charts that actually work and snack-sized bags of organic baby carrots at the ready. There’s an even smaller number who are horrifically abusive to their kids. But the biggest chunk by far are parents in the middle. They’re far from abusive, but they aren’t super-parents, either. They’re busy and stressed, so they’re too lenient one day and too harsh the next. They have outdated or no knowledge of child psychology, and they’re scrambling to figure it all out.
In 12 of 16 past cases in which a rising power has confronted a ruling power, the result has been bloodshed.
When Barack Obama meets this week with Xi Jinping during the Chinese president’s first state visit to America, one item probably won’t be on their agenda: the possibility that the United States and China could find themselves at war in the next decade. In policy circles, this appears as unlikely as it would be unwise.
And yet 100 years on, World War I offers a sobering reminder of man’s capacity for folly. When we say that war is “inconceivable,” is this a statement about what is possible in the world—or only about what our limited minds can conceive? In 1914, few could imagine slaughter on a scale that demanded a new category: world war. When war ended four years later, Europe lay in ruins: the kaiser gone, the Austro-Hungarian Empire dissolved, the Russian tsar overthrown by the Bolsheviks, France bled for a generation, and England shorn of its youth and treasure. A millennium in which Europe had been the political center of the world came to a crashing halt.
A professor of cognitive science argues that the world is nothing like the one we experience through our senses.
As we go about our daily lives, we tend to assume that our perceptions—sights, sounds, textures, tastes—are an accurate portrayal of the real world. Sure, when we stop and think about it—or when we find ourselves fooled by a perceptual illusion—we realize with a jolt that what we perceive is never the world directly, but rather our brain’s best guess at what that world is like, a kind of internal simulation of an external reality. Still, we bank on the fact that our simulation is a reasonably decent one. If it wasn’t, wouldn’t evolution have weeded us out by now? The true reality might be forever beyond our reach, but surely our senses give us at least an inkling of what it’s really like.
Neuroscientist James Fallon discovered through his work that he has the brain of a psychopath, and subsequently learned a lot about the role of genes in personality and how his brain affects his life.
In 2005, James Fallon's life started to resemble the plot of a well-honed joke or big-screen thriller: A neuroscientist is working in his laboratory one day when he thinks he has stumbled upon a big mistake. He is researching Alzheimer's and using his healthy family members' brain scans as a control, while simultaneously reviewing the fMRIs of murderous psychopaths for a side project. It appears, though, that one of the killers' scans has been shuffled into the wrong batch.
The scans are anonymously labeled, so the researcher has a technician break the code to identify the individual in his family, and place his or her scan in its proper place. When he sees the results, however, Fallon immediately orders the technician to double check the code. But no mistake has been made: The brain scan that mirrors those of the psychopaths is his own.
Neither the Islamic State nor al-Qaeda would be where they are today without Abu Abdullah al-Muhajir, who was recently killed in an American airstrike.
Last year, the Islamic State released a training video, one of a multipart series shot in Iraq. With its scenes of foot drills, target practice, and karate chops, it would have been entirely unremarkable were it not for a short classroom scene, in which an instructor walks viewers through the ideological curriculum forced upon new recruits to the ISIS cause. As he’s shown reeling off a list of some key topics in jihadist jurisprudence, one can glimpse a thick volume resting atop each of the 20 or so schoolroom desks—a manuscript that, while few would recognize it outside of jihadist circles, is instrumental to ISIS as a theological playbook that is used to justify the group’s most abhorrent acts.
President-elect Donald Trump has committed a sharp breach of protocol—one that underscores just how weird some important protocols are.
Updated on December 2 at 7:49 p.m.
It’s hardly remembered now, having been overshadowed a few months later on September 11, but the George W. Bush administration’s first foreign-policy crisis came in the South China Sea. On April 1, 2001, a U.S. Navy surveillance plane collided with a Chinese jet near Hainan Island. The pilot of the Chinese jet was killed, and the American plane was forced to land and its crew was held hostage for 11 days, until a diplomatic agreement was worked out. Sino-American relations remained tense for some time.
Unlike Bush, Donald Trump didn’t need to wait to be inaugurated to set off a crisis in the relationship. He managed that on Friday, with a phone call with the president of Taiwan, Tsai Ing-wen. It’s a sharp breach with protocol, but it’s also just the sort that underscores how weird and incomprehensible some important protocols are.
Life in Ohio's proud but economically abandoned small towns
Just over a decade ago, Matt Eich started photographing rural Ohio. Largely inhabited by what is now known as the “Forgotten Class” of white, blue-collar workers, Eich found himself drawn to the proud but economically abandoned small towns of Appalachia. Thanks to grants from the Economic Hardship Reporting Project and Getty Images, Eich was able to capture the family life, drug abuse, poverty, and listlessness of these communities. “Long before Trump was a player on the political scene, long before he was a Republican, these people existed and these problems existed,” Eich said. His new book, Carry Me Ohio, published by Sturm and Drang, is a collection of these images and the first of four books he plans to publish as part of The Invisible Yoke, a photographic meditation on the American condition. Even with a deep knowledge of the region, Eich was unprepared for the fury and energy that surrounded the election this year. “The anger is overpowering,” he said. “I knew what was going on, and I’m still surprised. I should have listened to the pictures.”
Trump's election has reopened questions that have long seemed settled in America—including the acceptability of open discrimination against minority groups.
When Stephen Bannon called his website, Breitbart, the “platform for the alt-right” this summer, he was referring to a movement that promotes white nationalism and argues that the strength of the United States is tied to its ethnic European roots. Its members mostly stick to trolling online, but much of what they do isn’t original or new: Their taunts often involve vicious anti-Semitism. They make it clear that Jews are not included in their vision of a perfect, white, ethno-state.
On the opposite side of American politics, many progressive groups are preparing to mount a rebellion against Donald Trump. They see solidarity among racial minorities as their goal, and largely blame Trump’s election on racism and white supremacy. Three-quarters of American Jews voted against Trump, and many support this progressive vision. Some members of these groups, though, have singled out particular Jews for their collusion with oppressive power—criticisms which range from inflammatory condemnations of Israel to full-on conspiracies about global Jewish media and banking cabals.
A few weeks ago, I was trying to call Cuba. I got an error message—which, okay, international telephone codes are long and my fingers are clumsy—but the phone oddly started dialing again before I could hang up. A voice answered. It had a British accent and it was reading: “...the moon was shining brightly. The Martians had taken away the excavating-machine…”
Apparently, I had somehow called into an audiobook of The War of the Worlds. Suspicious of my clumsy fingers, I double-checked the number. It was correct (weird), but I tried the number again, figuring that at worst, I’d learn what happened after the Martians took away the excavating machine. This time, I got the initial error message and the call disconnected. No Martians.
The Republican presidential candidate is not a Fascist, but his campaign bears notable similarities to the reign of Italian dictator Benito Mussolini.
Fascism has been back in the news with Donald Trump’s candidacy for the American presidency. His populist claim to speak for the white everyman, along with his menacing leadership style, have brought forth comparisons among this “homegrown authoritarian,” as President Barack Obama has called Trump, and foreign strongmen.
Trump is not a Fascist. He does not aim to establish a one-party state. Yet he has created a one-man-led political movement that does not map onto traditional U.S. party structures or behave in traditional ways. This is how Fascism began as well.
A century before Trump, Benito Mussolini burst onto the Italian political scene, confounding the country’s political establishment with his unorthodox doctrine and tactics and his outsized personality. Mussolini’s rise offers lessons for understanding the Trump phenomenon—and why he was able to disarm much of the American political class.
