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.
Forget credit hours—in a quest to cut costs, universities are simply asking students to prove their mastery of a subject.
MANCHESTER, Mich.—Had Daniella Kippnick followed in the footsteps of the hundreds of millions of students who have earned university degrees in the past millennium, she might be slumping in a lecture hall somewhere while a professor droned. But Kippnick has no course lectures. She has no courses to attend at all. No classroom, no college quad, no grades. Her university has no deadlines or tenure-track professors.
Instead, Kippnick makes her way through different subject matters on the way to a bachelor’s in accounting. When she feels she’s mastered a certain subject, she takes a test at home, where a proctor watches her from afar by monitoring her computer and watching her over a video feed. If she proves she’s competent—by getting the equivalent of a B—she passes and moves on to the next subject.
The Wall Street Journal’s eyebrow-raising story of how the presidential candidate and her husband accepted cash from UBS without any regard for the appearance of impropriety that it created.
The Swiss bank UBS is one of the biggest, most powerful financial institutions in the world. As secretary of state, Hillary Clinton intervened to help it out with the IRS. And after that, the Swiss bank paid Bill Clinton $1.5 million for speaking gigs. TheWall Street Journal reported all that and more Thursday in an article that highlights huge conflicts of interest that the Clintons have created in the recent past.
The piece begins by detailing how Clinton helped the global bank.
“A few weeks after Hillary Clinton was sworn in as secretary of state in early 2009, she was summoned to Geneva by her Swiss counterpart to discuss an urgent matter. The Internal Revenue Service was suing UBS AG to get the identities of Americans with secret accounts,” the newspaper reports. “If the case proceeded, Switzerland’s largest bank would face an impossible choice: Violate Swiss secrecy laws by handing over the names, or refuse and face criminal charges in U.S. federal court. Within months, Mrs. Clinton announced a tentative legal settlement—an unusual intervention by the top U.S. diplomat. UBS ultimately turned over information on 4,450 accounts, a fraction of the 52,000 sought by the IRS.”
Even when a dentist kills an adored lion, and everyone is furious, there’s loftier righteousness to be had.
Now is the point in the story of Cecil the lion—amid non-stop news coverage and passionate social-media advocacy—when people get tired of hearing about Cecil the lion. Even if they hesitate to say it.
But Cecil fatigue is only going to get worse. On Friday morning, Zimbabwe’s environment minister, Oppah Muchinguri, called for the extradition of the man who killed him, the Minnesota dentist Walter Palmer. Muchinguri would like Palmer to be “held accountable for his illegal action”—paying a reported $50,000 to kill Cecil with an arrow after luring him away from protected land. And she’s far from alone in demanding accountability. This week, the Internet has served as a bastion of judgment and vigilante justice—just like usual, except that this was a perfect storm directed at a single person. It might be called an outrage singularity.
Bernie Sanders and Jeb Bush look abroad for inspiration, heralding the end of American exceptionalism.
This election cycle, two candidates have dared to touch a third rail in American politics.
Not Social Security reform. Not Medicare. Not ethanol subsidies. The shibboleth that politicians are suddenly willing to discuss is the idea that America might have something to learn from other countries.
The most notable example is Bernie Sanders, who renewed his praise for Western Europe in a recent interview with Ezra Klein. “Where is the UK? Where is France? Germany is the economic powerhouse in Europe,” Sanders said. “They provide health care to all of their people, they provide free college education to their kids.”
On ABC’s This Week in May, George Stephanopoulos asked Sanders about this sort of rhetoric. “I can hear the Republican attack ad right now: ‘He wants American to look more like Scandinavia,’” the host said. Sanders didn’t flinch:
A hawkish senator doesn't apply the lessons of Iraq
Earlier this week, Senator Lindsey Graham, a hawkish Republican from South Carolina, used a Senate Armed Services Committee hearing to stage a theatrical display of his disdain for the Obama administration’s nuclear deal with Iran.
The most telling part of his time in the spotlight came when he pressed Defense Secretary Ashton Carter to declare who would win if the United States and Iran fought a war:
Here’s a transcript of the relevant part:
Graham: Could we win a war with Iran? Who wins the war between us and Iran? Who wins? Do you have any doubt who wins?
Carter: No. The United States.
Graham: We. Win.
Little more than a decade ago, when Senator Graham urged the invasion of Iraq, he may well have asked a general, “Could we win a war against Saddam Hussein? Who wins?” The answer would’ve been the same: “The United States.” And the U.S. did rout Hussein’s army. It drove the dictator into a hole, and he was executed by the government that the United States installed. And yet, the fact that the Iraqi government of 2002 lost the Iraq War didn’t turn out to mean that the U.S. won it. It incurred trillions in costs; thousands of dead Americans; thousands more with missing limbs and post-traumatic stress disorder and years of deployments away from spouses and children; and in the end, a broken Iraq with large swaths of its territory controlled by ISIS, a force the Iraqis cannot seem to defeat. That’s what happened last time a Lindsey Graham-backed war was waged.
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.
The IOC’s selection of Beijing as the host of its 2022 games is met with a lukewarm response.
When the International Olympic Committee selected Beijing on Friday as the host for the 2022 Winter Olympic Games, the Chinese capital became the first city to have hosted both the Summer and Winter games. This, most likely, isn’t coincidental: Beijing’s hosting of the Summer games in 2008 was generally considered a success, and Almaty, the Kazakh city whose bid placed second, lacks comparable experience.
A closer examination of Beijing’s 2022 bid, though, reveals the selection is far more peculiar than it seems at first glance. One reason: It barely snows in Beijing. China’s northern plain is extremely dry, and what precipitation that falls in the capital tends to occur during the summer. Beijing’s Olympic planners have assured the IOC this won’t be a problem—the country will simply use artificial snow to accommodate events, such as skiing, that require it.
Jim Gilmore joins the race, and the Republican field jockeys for spots in the August 6 debate in Cleveland.
After decades as the butt of countless jokes, it’s Cleveland’s turn to laugh: Seldom have so many powerful people been so desperate to get to the Forest City. There’s one week until the Republican Party’s first primary debate of the cycle on August 6, and now there’s a mad dash to get into the top 10 and qualify for the main event.
With former Virginia Governor Jim Gilmore filing papers to run for president on July 29, there are now 17 “major” candidates vying for the GOP nomination, though that’s an awfully imprecise descriptor. It takes in candidates with lengthy experience and a good chance at the White House, like Scott Walker and Jeb Bush; at least one person who is polling well but is manifestly unserious, namely Donald Trump; and people with long experience but no chance at the White House, like Gilmore. Yet it also excludes other people with long experience but no chance at the White House, such as former IRS Commissioner Mark Everson.
Most of the big names in futurism are men. What does that mean for the direction we’re all headed?
In the future, everyone’s going to have a robot assistant. That’s the story, at least. And as part of that long-running narrative, Facebook just launched its virtual assistant. They’re calling it Moneypenny—the secretary from the James Bond Films. Which means the symbol of our march forward, once again, ends up being a nod back. In this case, Moneypenny is a send-up to an age when Bond’s womanizing was a symbol of manliness and many women were, no matter what they wanted to be doing, secretaries.
Why can’t people imagine a future without falling into the sexist past? Why does the road ahead keep leading us back to a place that looks like the Tomorrowland of the 1950s? Well, when it comes to Moneypenny, here’s a relevant datapoint: More than two thirds of Facebook employees are men. That’s a ratio reflected among another key group: futurists.
Who can devise the most convoluted way to wipe out the Islamic State?
Everyone with a stake in Middle Eastern geopolitics publicly declares that ISIS must be defeated. Yet opinions range widely on how this should be achieved.
Saudi Arabia, for example, believes ISIS cannot be defeated unless Syrian President Bashar al-Assad is removed from power. Turkey has just convinced NATO nations that the war against ISIS can only be won if Turkey’s traditional Kurdish opponents are neutralized first. Israel sees only one way to defeat ISIS: destroy Iran’s nuclear program and clip its wings regionally.
So what explains these apparently contradictory aims? The cynical view would be that all these parties are less interested in defeating ISIS than in achieving their own regional goals, and that they’re only pretending to be concerned about wiping out the group. Clearly, however, there is no place for cynicism in Middle Eastern politics. Everyone involved in the region is known to be sincere, albeit in radically different ways.
