oil

  • 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.

  • 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.)
  • 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.
  • 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.)
  • 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.

TARGET2 as a scapegoat for German errors | vox - 0 views

  • This coincided with the bubble years in peripheral Eurozone countries (2003-07). The effect of this is that Germany accumulated large net claims on Eurozone countries, which at the end of 2011 amounted to €634 billion.
  • These current account surpluses did not lead to TARGET2 claims during the bubble years because the counterpart of these surpluses were increasing claims held by (mainly) German banks against the other Eurozone countries.
  • the German banking system was lending the money to other Eurozone countries to allow them to buy surplus German products – a highly risky affair.

  • This created the illusion that no risk was involved; in fact the risks were increasing every year.
  • It should have been obvious that the debtor countries could get into payment difficulties as they were piling up debt made possible by the loans of German banks.
  • If there is a breakup of the Eurozone, Germany will face the risk that some debtor countries default on their debt. But again this risk is not affected by the size of the TARGET2 claims of Germany.
  • The risk that Germany faces as a result of its net exposure to other Eurozone countries is therefore entirely of the country’s own making.
  • Since 2009, when the TARGET2 balances started to take off, current account deficits of the peripheral countries as a whole declined from 9.1% of their GDP to 4.5%. These declines were mainly due to deep recessions in these countries.
  • Sinn (2012) argues that these deficits would have had to decline even faster had there been no financing through the TARGET2 mechanism. This is certainly true. But this is the same as saying that these countries should have pushed their economies into even deeper recessions.
  • The main reason why German TARGET2 claims have increased so much since 2010 is capital flows. The flows have taken two forms.
  • The first one came about when German banks unloaded their loans made to peripheral countries into the balance sheet of the Bundesbank.
  • The second one was the result of non-residents shifting their deposits from their local banks into the German banking system out of fear of a breakup of the Eurozone.
  • This led German banks to stop their credit lines to southern banks (and other northern EZ banks followed)
  • Thus in the scenario of a breakup, with or without TARGET2 claims, the risk of large losses for the German taxpayer is very similar.
  • the Bundesbank can eliminate the risk of such last minute accumulations of TARGET2 balances by converting euros into new German marks only for German residents.

EUobserver / Former ECB chief blames governments for euro-crisis - 1 views

  • Former ECB chief blames governments for euro-crisis
  • But the 71-year-old French banker said he had warned EU governments of growing economic divergences in the euro area as far back as 2005 and that he had criticised member states, notably France and Germany, for ignoring the deficit and debt rules which underpin the common currency.
  • Trichet noted that the ECB intervened on bond markets and bought up Greek debt as early as May 2010, when he was still chief and when the first-ever EU bailout was still being drafted. It interevened again in 2011 to buy Italian and Spanish debt when investors started to bet against the larger euro-states.

  • "If we wouldn't have bought Spanish and Italian debt - a move which was highly criticised at the time - we would be in a totally different situation now," he added.
  • Turning to Ireland, where the government first used taxpayers’ money to guarnatee all deposits in Irish banks and then had to seek a painful rescue package, Trichet said "nobody advised them to do so."
  • Back in 2010, the IMF said Greece could never repay its debt and should write off some of its private and public liabilities. But the EU, under a deal by the French and German leaders, wanted the private sector to take the hit alone in what it called “private sector involvement [PSI],” putting Trichet in a tough spot.
  • Despite his actions, PSI came back in a vengeance in Cyprus in 2013, when it was renamed a “bail-in,” and when it saw lenders snatch the savings of well-to-do private depositors on top of private bondholders.
