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.
How the election looks to backers of the Republican nominee
Perhaps the hardest thing to do in contemporary American politics is to imagine how the world looks from the other side. I’ve made no secret of why, as a Republican, I oppose Donald Trump and what he stands for. But I’ve also been talking to his supporters and advisors, trying to understand how they see and hear the same things that I do, and draw such very different conclusions. What follows isn’t a transcription—it’s a synthesis of the conversations I’ve had, and the insights I’ve gleaned, presented in the voice of an imagined Trump supporter.
“You people in the Acela corridor aren’t getting it. Again. You think Donald Trump is screwing up because he keeps saying things that you find offensive or off-the-wall. But he’s not talking to you. You’re not his audience, you never were, and you never will be. He’s playing this game in a different way from anybody you’ve ever seen. And he’s winning too, in a different way from anybody you’ve ever seen.
Last night, in her overall very successful acceptance speech, Hillary Clinton said with ruthless precision about her opponent:
Ask yourself: Does Donald Trump have the temperament to be Commander-in-Chief?
Donald Trump can't even handle the rough-and-tumble of a presidential campaign.
He loses his cool at the slightest provocation. When he's gotten a tough question from a reporter. When he's challenged in a debate. When he sees a protestor at a rally.
Emphasis added, as it was in her delivery:
Imagine—if you dare, imagine—imagine him in the Oval Office facing a real crisis. A man you can bait with a tweet is not a man we can trust with nuclear weapons.
I can’t put it any better than Jackie Kennedy did after the Cuban Missile Crisis. She said that what worried President Kennedy during that very dangerous time was that a war might be started—not by big men with self-control and restraint, but by little men—the ones moved by fear and pride.
Narcissism, disagreeableness, grandiosity—a psychologist investigates how Trump’s extraordinary personality might shape his possible presidency.
In 2006, Donald Trump made plans to purchase the Menie Estate, near Aberdeen, Scotland, aiming to convert the dunes and grassland into a luxury golf resort. He and the estate’s owner, Tom Griffin, sat down to discuss the transaction at the Cock & Bull restaurant. Griffin recalls that Trump was a hard-nosed negotiator, reluctant to give in on even the tiniest details. But, as Michael D’Antonio writes in his recent biography of Trump, Never Enough, Griffin’s most vivid recollection of the evening pertains to the theatrics. It was as if the golden-haired guest sitting across the table were an actor playing a part on the London stage.
“It was Donald Trump playing Donald Trump,” Griffin observed. There was something unreal about it.
A church facing setbacks elsewhere finds an unlikely foothold.
At the end of 2013, in the low-slung, industrial Taiwanese city of Kaohsiung, a bevy of officials came to attend the ribbon cutting of a huge former hotel that had undergone a top-to-bottom, multimillion-dollar renovation. Speaking before the throngs of celebrants who blocked the flow of traffic, Taiwan’s deputy director of the Ministry of the Interior praised the group that funded the renovation and presented them, for the 10th year straight, with the national “Excellent Religious Group” award.
“For years you have dedicated your time and lives to anti-drug work and human- rights dissemination,” said the director, echoing praise offered by the mayor’s office and the president’s national-policy adviser.
A federal appeals court finds the impact of the state’s voting law can only be explained by “discriminatory intent.”
Updated on July 29 at 9:30 p.m.
DURHAM, N.C.—The Fourth Circuit Court of Appeals struck down key portions of North Carolina’s strict 2013 voting law on Friday, delivering a stern rebuke to the state’s Republican General Assembly and Governor Pat McCrory. The three-judge panel in Richmond, Virginia, unanimously concluded that the law was racially discriminatory, and it blocked a requirement that voters show photo identification to vote and restored same-day voter registration, a week of early voting, pre-registration for teenagers, and out-of-precinct voting.
“In what comes as close to a smoking gun as we are likely to see in modern times, the State’s very justification for a challenged statute hinges explicitly on race—specifically its concern that African Americans, who had overwhelmingly voted for Democrats, had too much access to the franchise,” wrote Judge Diana Gribbon Motz.
The comparatively less flashy, less spirited former First Kid managed to show her mom’s softer side at the DNC on Thursday.
Yes, yes, yes. Chelsea Clinton is not the most charismatic orator—as the Twittersphere was happy to point out during her brief address on Thursday night. She is like her mother that way. There’s something not quite natural about her self-presentation. She’s not stilted, exactly. But she can come across as too cautious, too reserved, too conscious of other people’s eyes upon her.
But, let’s face it, as the lead-in to Hillary’s big nominating speech, a little bit of boring was called for. Unlike some of this convention’s high-wattage speakers, there was zero chance Chelsea was going to upstage Hillary with a barnburner or tear-jerker. Chelsea wasn’t there to pump up the crowd. Her role was to comfort, to explain, to cajole, with an eye toward giving Americans a glimpse of her mother’s softer side.
The Islamic State is no mere collection of psychopaths. It is a religious group with carefully considered beliefs, among them that it is a key agent of the coming apocalypse. Here’s what that means for its strategy—and for how to stop it.
What is the Islamic State?
Where did it come from, and what are its intentions? The simplicity of these questions can be deceiving, and few Western leaders seem to know the answers. In December, The New York Times published confidential comments by Major General Michael K. Nagata, the Special Operations commander for the United States in the Middle East, admitting that he had hardly begun figuring out the Islamic State’s appeal. “We have not defeated the idea,” he said. “We do not even understand the idea.” In the past year, President Obama has referred to the Islamic State, variously, as “not Islamic” and as al-Qaeda’s “jayvee team,” statements that reflected confusion about the group, and may have contributed to significant strategic errors.
Physicists can’t agree on whether the flow of future to past is real or a mental construct.
Einstein once described his friend Michele Besso as “the best sounding board in Europe” for scientific ideas. They attended university together in Zurich; later they were colleagues at the patent office in Bern. When Besso died in the spring of 1955, Einstein—knowing that his own time was also running out—wrote a now-famous letter to Besso’s family. “Now he has departed this strange world a little ahead of me,” Einstein wrote of his friend’s passing. “That signifies nothing. For us believing physicists, the distinction between past, present, and future is only a stubbornly persistent illusion.”
Einstein’s statement was not merely an attempt at consolation. Many physicists argue that Einstein’s position is implied by the two pillars of modern physics: Einstein’s masterpiece, the general theory of relativity, and the Standard Model of particle physics. The laws that underlie these theories are time-symmetric—that is, the physics they describe is the same, regardless of whether the variable called “time” increases or decreases. Moreover, they say nothing at all about the point we call “now”—a special moment (or so it appears) for us, but seemingly undefined when we talk about the universe at large. The resulting timeless cosmos is sometimes called a “block universe”—a static block of space-time in which any flow of time, or passage through it, must presumably be a mental construct or other illusion.
Chris Morris’s brutal satire aired its last and most controversial episode in 2001, but its skewering of the news media feels more relevant than ever.
A sex offender is thrown in the stocks, presented with a small child, and asked if he wants to molest him. A mob of protestors is thrown a “dummy full of guts” that is stomped to pieces within seconds. A radio host insists that pedophiles have “more genes in common with crabs” than the rest of humanity, insisting, “There’s no real evidence for [that], but it is scientific fact.”
It’s hard to pinpoint the most cringe-inducing moment on “Paedogeddon,” a special episode of the British TV satire Brass Eye. But 15 years after the episode aired, it remains a totemic, terrifying satirical vision. Few comedies since have dared to cross the boundaries of taste with such impunity.
“Paedogeddon” aired in the U.K. in the summer of 2001, a year after the murder of a young girl had sparked national hysteria over the country’s sex-offender registry. Britain’s most-read newspaper led a campaign to publish the names and locations of all 110,000 convicted sex offenders, prompting a riot in which an angry mob ransacked the home of an ex-con. Brass Eye, a parody of a 60 Minutes-like newsmagazine show, had been dormant after airing one season in the UK in 1997. But it returned four years later for this surprise broadcast, one that saw its furious (fictional) anchors barking from a dark studio about the plague of seemingly super-powered child molesters stalking the nation, holding a funhouse mirror up to the climate of paranoia and fear that had built up around the country. It was a bold, wildly insensitive piece of comedy, but one that captured the growing madness of the 24-hour news media and foreshadowed some uglier aspects of its future.
Psychologists have long debated how flexible someone’s “true” self is.
Almost everyone has something they want to change about their personality. In 2014, a study that traced people’s goals for personality change found that the vast majority of its subjects wanted to be more extraverted, agreeable, emotionally stable, and open to new experiences. A whopping 97 percent said they wished they were more conscientious.
These desires appeared to be rooted in dissatisfaction. People wanted to become more extraverted if they weren’t happy with their sex lives, hobbies, or friendships. They wanted to become more conscientious if they were displeased with their finances or schoolwork. The findings reflect the social psychologist Roy Baumeister’s notion of “crystallization of discontent”: Once people begin to recognize larger patterns of shortcomings in their lives, he contends, they may reshuffle their core values and priorities to justify improving things.
