What If We Never Run Out of Oil? - Charles C. Mann - The Atlantic - 0 views

  • In most cases, mining tar sands involves drilling two horizontal wells, one above the other, into the bitumen layer; injecting massive gouts of high-pressure steam and solvents into the top well, liquefying the bitumen; sucking up the melted bitumen as it drips into the sand around the lower well; and then refining the bitumen into “synthetic crude oil.”
  • Economists sometimes describe a fuel in terms of its energy return on energy invested (EROEI), a measure of how much energy must be used up to acquire, process, and deliver the fuel in a useful form. OPEC oil, for example, is typically estimated to have an EROEI of 12 to 18, which means that 12 to 18 barrels of oil are produced at the wellhead for every barrel of oil consumed during their production. In this calculation, tar sands look awful: they have an EROEI of 4 to 7. (Steaming out the bitumen also requires a lot of water. Environmentalists ask, with some justification, where it all is going to come from.)
  • To obtain shale gas, companies first dig wells that reach down thousands of feet. Then, with the absurd agility of anime characters, the drills wriggle sideways to bore thousands of feet more through methane-bearing shale. Once in place, the well injects high-pressure water into the stone, creating hairline cracks. The water is mixed with chemicals and “proppant,” particles of sand or ceramic that help keep the cracks open once they have formed. Gas trapped between layers of shale seeps past the proppant and rises through the well to be collected.

  • Water-assisted fracturing has been in use since the late 1940s, but it became “fracking” only recently, when it was married with horizontal drilling and the advanced sensing techniques that let it be used deep underground. Energy costs are surprisingly small; a Swiss-American research team calculated in 2011 that the average EROEI for fracked gas in a representative Pennsylvania county was about 87—about six times better than for Persian Gulf oil and 16 times better than for tar sands. (Fracking uses a lot of Water, though, and activists charge that the chemicals contaminate underground Water supplies.)
  • Today, a fifth of U.S. energy consumption is fueled by coal, mainly from Appalachia and the West, a long-term energy source that has provided jobs for millions, a century-old way of life
  • and pollution that kills more than 10,000 Americans a year (that estimate is from a 2010 National Research Council study).
  • Roughly speaking, burning coal produces twice as much carbon dioxide as burning the equivalent amount of natural gas. Almost all domestic coal is used to generate electricity—it produces 38 percent of the U.S. power supply. Fracking is swiftly changing this: in 2011, utilities reported plans to shut down 57 of the nation’s 1,287 coal-fired generators the following year. Largely in consequence, U.S. energy-related carbon-dioxide emissions have dropped to figures last seen in 1995. Since 2006, they have fallen more than those from any other nation in the world.
  • In the sort of development that irresistibly attracts descriptors like ironic, Germany, often touted as an environmental model for its commitment to solar and wind power, has expanded its use of coal, and as a result is steadily increasing its carbon-dioxide output. Unlike Americans, Europeans can’t readily switch to natural gas; Continental nations, which import most of their natural gas, agreed to long-term contracts that tie its price to the price of oil, now quite high.
  • Several researchers told me that the current towel-snapping between Beijing and Tokyo over islands in the East China Sea is due less to nationalistic posturing than to nearby petroleum deposits.)
  • In mid-March, Japan’s Chikyu test ended a week early, after sand got in the well mechanism. But by then the researchers had already retrieved about 4 million cubic feet of natural gas from methane hydrate, at double the expected rate.
  • What is known, says Timothy Collett, the energy-research director for the USGS program, is that some of the gulf’s more than 3,500 oil and gas wells are in gas-hydrate areas.
  • In Dutch-disease scenarios, oil weakens all the pillars but one—the petroleum industry, which bloats steroidally.
  • Because the national petroleum company, with its gush of oil revenues, is the center of national economic power, “the ruler typically puts a loyalist in charge,” says Michael Ross, a UCLA political scientist and the author of The Oil Curse (2012). “The possibilities for corruption are endless.” Governments dip into the oil kitty to reward friends and buy off enemies. Sometimes the money goes to simple bribes; in the early 1990s, hundreds of millions of euros from France’s state oil company, Elf Aquitaine, lined the pockets of businessmen and politicians at home and abroad.
  • How much of Venezuela’s oil wealth Hugo Chávez hijacked for his own political purposes is unknown, because his government stopped publishing the relevant income and expenditure figures. Similarly, Ross points out, Saddam Hussein allocated more than half the government’s funds to the Iraq National Oil Company; nobody has any idea what happened to the stash, though, because INOC never released a budget. (Saddam personally directed the nationalization of Iraqi oil in 1972, then leveraged his control of petroleum revenues to seize power from his rivals.)
  • “How will the royal family contain both the mullahs and the unemployed youth without a slush fund?”
  • It seems fair to say that if autocrats in these places were toppled, most Americans would not mourn. But it seems equally fair to say that they would not necessarily be enthusiastic about their replacements.

The Truth about Fracking - Kevin D. Williamson - National Review Online - 0 views

  • The water makes the fractures, and the sand keeps them open. There’s some other stuff in that fracking blend, too: biocides, for one thing, not very different from what’s in your swimming pool, to keep bacteria and algae and other gunk from growing in the water and clogging up the works. There are also some friction reducers, because water and sand moving at speed can produce a lot of wear and tear (cf. the Grand Canyon), and the occasional jolt of 7 percent hydrochloric acid solution for boring out holes in the concrete. The mix is 99+ percent water and sand, and the rest of the stuff is mostly run-of-the-mill industrial chemicals (those friction-reducers use a polymer that also is used in children’s toys, for example). Real concerns, but not exactly an insurmountable environmental challenge.

  • The magic is in that head: GE has put a small heat pump up there, and the GeoSpring pulls ambient heat from the air to help heat water. As a result, the GeoSpring uses some 60 percent less electricity than a typical water heater. (You can also control it using your iPhone.)

U.S. Ports Seek to Lure Big Ships After Panama Canal Expands - NYTimes.com - 0 views

  • But, he said, containers loaded on the West Coast, which has built up its container yards and highway and rail infrastructure, can outrun those that travel to the East Coast by water, and that can make the difference when speed and dependability are more important than cost alone

Why Is Zambia So Poor? And Will Things Ever Get Better? - 0 views

  • Sixty-four percent of the population lives on less than $1 per day, 14 percent have HIV, 40 percent don’t have access to clean drinking water. Almost 90 percent of women in rural areas cannot read or write. Name a category—schools, health care, environment—and I’ll give you statistics that will depress the shit out of you.
  • For more than 150 years, the only reason to come to Kitwe—to Zambia, really—was the copper.
  • Most of the buildings in Kitwe, the roads, the health clinics, the schools, were built by the national mining company
  • ...25 more annotations...
  • At its peak, the Zambia Consolidated Copper Mines company employed more than 65,000 Zambians and carried out services like water delivery and waste collection for five cities in the Copper Belt Province.
  • Mining employment has dropped to just 30,000, half of its glory-days peak, and the job of maintaining all that company housing and infrastructure has reverted back to the government.
  • The stats identify Switzerland as Zambia’s primary export market. This is not an indicator that Zambia hosts a thriving chocolate and suspenders sector, but rather that its copper trades are booked in the jurisdiction where they are least likely to be taxed.
  • Many of the mining companies pay just 0.6 percent royalties to Zambia, far below the already-meager industry standard of three percent.
  • And then there’s the Chinese. They arrived like a well-packed picnic, everything in shipping crates ready to be unpacked. Their own materials, their own equipment, their own workers, their own fences. If you were designing a foreign investment not to benefit the host community, this is what it would look like.
  • This is Namwile Uzondile, the director of a rural health education project.
  • Last year Namwile conducted a survey of prostitutes here in Kitwe, and found that at least half of them had education certificates, but couldn’t find work. Most had been married off early, 15 or 16, and since then had either left their husbands or lost them to AIDS.
  • First, you go to the tribal chief. Ninety-four percent of the land in Zambia is customary or traditional, no one has a title to it. It’s not just sitting there, people are living on it, farming, grazing animals, it’s just technically under the control of a chief.
  • In Zambia most of the chiefs require a gift just to get a meeting. This might mean taking them lunch at a restaurant in Lusaka, or it could mean buying their daughter a car—it’s up to them.
  • Another reason Zambia lacks skills is that some parts of the workforce operate as cartels. Take lawyers. Zambia only has 1,000 of them, and they’re concentrated where the money is: Lusaka (government), Copper Belt (mining) and Livingstone (safari tourists).
  • Last year, only six lawyers were admitted to the bar out of 164 who took the exam. The year before that, it was 16 out of 145. Keep in mind, these aren’t people coming in off the streets. These are people who have a law degree.
  • More than 60 percent of Zambia’s government revenue comes from the copper mines.
  • Taxing all this informal activity would be costly in both resources and voter goodwill. In 2012, Zambia collected just $2.3 million in income taxes from its citizens.
  • It goes as high up as you want to follow it. Michael Sata, the president of Zambia, appointed his uncle the finance minister, his nephew the deputy finance minister, his niece the local government minister, and cousins as ambassador to Japan and chief justice.
  • Zambia’s cabinet has ballooned to 20 ministers and 47 deputy ministers, the largest in Africa. With salaries three to four times higher than opposition MPs and each ministerial post bundled with perks like a company car, free fuel, house servants, and mobile phone talk-time, you get the feeling politicians aren’t jumping from opposition into government on moral sentiment alone.
  • But even if Zambia was run by a coalition of charitable technocrats and Mormon philanthropists, that wouldn’t solve the most fundamental problem of all: There simply isn’t that much money to go around.
  • In 2011, Zambia spent a total of $4.3 billion running itself. Stretch that to cover every man, woman, and child, and it amounts to just $325 per person per year. That amount—less than a dollar per person per day—has to cover education, health care, infrastructure, law enforcement, foreign debt … everything.
  • Now she goes all NGO. “Little government capacity,” she says, is the nicest way to put it. “There are simply no systems for routine government services,” she says. Getting a license, a permit, certificates, approvals to start work, visas for expats to fly down here—nothing is in one place, nothing is fast or easy.
  • And that’s just the bureaucracy. Then there are the cops that pull you over to ask for 50 kwacha ($10); the schools with slots reserved for paying parents; the hospitals that swear the earliest appointment, the only available medicine, is six months away until you reach into your pocket.
  • “Sometimes we have to pay for the inspectors to come to our mines,” Jane says.
  • The conversation goes like this: Jane tells the local certification body that she needs an inspector to sign off for a permit. The local certification body tells her that they would be happy to come out to the site, but they don’t have fuel for their cars, or enough petty cash to pay per diems. Jane offers to pay their costs, but only their costs, and the payments aren’t related to clearing the inspection.
  • The company has even paid the police to follow up on complaints or to investigate thefts. “They say, ‘We don’t have this in our budget’ or ‘We’ll need you to pay for it,’” Jane says. So the company fixes the police cars, covers their travel expenses, treats them to lunch.
  • “We tell them, ‘The company I work for, we’re not going to pay up.’ But at the end of the day, they know you’re on a short timeline, and they aren’t.”
  • Thomas’ family told him his nephews didn’t need to be in school. From their perspective, that’s not totally irrational. In a country with so few formal jobs and so much competition for getting them, I can see how spending hundreds of hours, thousands of kwachas, on education would seem superfluous. Thomas’ daughter wants to become a lawyer. You could almost forgive Thomas if he told her that the bar exam failure rate is more than 90 percent, so what’s the use?
  • International investors pledged $750 million last year to build infrastructure.

Fear of Fracking by Jeffrey Frankel - Project Syndicate - 0 views

  • CAMBRIDGE – Against all expectations, US emissions of carbon dioxide into the atmosphere, since peaking in 2007, have fallen by 12% as of 2012, back to 1995 levels. The primary reason, in a word, is “fracking.”
  • Just ten years ago, the natural-gas industry was so sure that domestic production was reaching its limit that it made large investments in terminals to import liquefied natural gas (LNG). Yet fracking has increased supply so rapidly that these facilities are now being converted to export LNG.
  • Natural gas emits only half as much CO2 as coal, and occupies a rapidly increasing share of electricity generation – up 37% since 2007, while coal’s share has plummeted by 25%.
  • ...4 more annotations...
  • Meanwhile, the share of coal – the dirtiest fuel – has been rising, not falling, in the rest of the world’s energy mix.
  • Moving beyond economics, America’s reduction in net energy imports – which have already fallen by one-half since 2007 – means that its foreign policy will be less constrained by events in the Middle East. In Europe, the new technology could similarly break Russia’s politically troublesome stranglehold on natural-gas supplies.
  • Put differently, if the world continues to build coal-fired power plants at the current rate, those plants will still be around in 2050, regardless of what other technologies become viable in the meantime.
  • Even a serious fracking mishap would be unlikely to cause as much damage as the Deepwater Horizon oil spill in 2010, the Fukushima nuclear catastrophe in 2011, or coal-mining tragedies that play out dramatically in frequent explosions and collapses (and more insidiously in the form of lung disease, water pollution, and soil erosion).

  • Today renewable energy supplies only about 6 percent of American demand. And most of that comes from water flowing through dams. Solar energy contributes next to nothing.
  • The arithmetic is merciless. To make it likely that the world’s temperature will rise no more than 2 degrees Celsius above the average of the preindustrial era — a target agreed to by the world’s governments in 2010 — humanity must spew no more than 900 billion more tons of carbon dioxide into the air from now through 2050 and only 75 billion tons after that, according to an authoritative new study in Britain.
  • The United States Energy Information Administration forecasts that global energy consumption will grow 56 percent between now and 2040.
  • “We have trillions of tons of coal resources in the world,” Vic Svec, spokesman for Peabody Energy, told me. “You can expect the world to use them all.”
  • The only way around this is to put something in coal’s place, at a reasonably competitive price. Neither the warm glow of the sun nor the restless power of the wind is going to do the trick, at least not soon enough to make a difference in the battle to prevent climate change.

An interview with Athanasios Orphanides: What happened in Cyprus | The Economist - 0 views

  • Cyprus had developed its financial center over three decades ago by having double taxation treaties with a number of countries, the Soviet Union for example. That means if profits are booked and earned and taxed in Cyprus, they are not taxed again in the other country. Russian deposits are there because Cyprus has a low corporate tax rate, much like Malta and Luxembourg, which annoys some people in Europe.
  • In addition, Cyprus has a legal system based on English law and follows English accounting rules
  • This government took a country with excellent fiscal finances, a surplus in fiscal accounts, and a banking system that was in excellent health. They started overspending, not only for unproductive government expenditures but also they raised implicit liabilities by raising pension promises, and so forth.

  • The size of the banking sector and exposure to Greece were known risks but at that time there was no banking problem in Cyprus
  • The containers were part of a shipment going from Iran to Syria that was intercepted in Cypriot waters after a tip from the U.S. The president took the decision to keep the ammunition. [NOTE: An independent prosecutor found that Christofias has ignored repeated warnings and pleas to destroy or safeguard the ammunition, apparently in hopes of one day returning it to Syria or Iran.]
  • Instead, they started lobbying the Russian government to give them a loan that would help them finance the country for a couple more years, and Russia came through, unfortunately,
  • I say unfortunately because as a result the government could keep operating and accumulating deficits without taking corrective action.
  • The next important date was the October 26-27, 2011 meeting of the EU council in Brussels where European leaders decided to wipe out what ended up being about 80% of the value of Greek debt that the private sector held. Every bank operating in Greece, regardless of where it was headquartered, had a lot of Greek debt.
  • For Cyprus, the writedown of Greek debt was between 4.5 and 5 billion euro, a substantial chunk of capital.
  • The second element of the decision taken by heads of states was to instruct the EBA to do a so- called capital exercise that marked to market sovereign debt and effectively raised abruptly capital requirements. The exercise required banks to have a core tier-1 ratio of 9%, and on top of that a buffer to make up for differences in market and book value of government debt. That famous capital exercise created the capital crunch in the euro area which is the cause of the recession we've had in the euro area for the last 2 years.
  • The Basle II framework that governments adopted internationally, and that the EU supervisory framework during this period also incorporated, specifies that holdings of government debt in a states' own currency are a zero-risk-weight asset, that is they are assigned a weight of zero in calculating capital requirements.
  • the governments should have agreed to make the EFSF/ESM available for direct recapitalization of banks instead of asking each government to be responsible for the capitalization.
  • Following a downgrading in late June 2012, all three major rating agencies rated the sovereign paper Cyprus below investment grade. According to ECB rules, that made the government debt not eligible as collateral for borrowing from the eurosystem, unless the ECB suspended the rules, as it had done for the cases of Greece, Portugal and Ireland. In the case of Cyprus, the ECB decided not to suspend the eligibility rule.
  • The governments have created risk in what before last week were considered perfectly safe deposits. This is going to have a chilling effect on deposits in any bank in a country perceived to be weak. This will mean the cost of funding will increase in the periphery of Europe and as a result, the cost of financing for businesses and households will increase. That will add to the divergences we already have and make the recession in the periphery of Europe deeper than it already is. This is really a disaster for European economic management as a whole.
