    So the CO2 in your soda is, in fact, stored industrial carbon. So when we hear about refrigerators and air conditioners becoming far more efficient by using CO2 as a coolant, we don't have to worry about the CO2. All we have to worry about is how to get this new refrigerant adopted as quickly as possible.

    The U.S. Department of Energy (DOE) announced that it will provide $36 million for 15 projects aimed at furthering the development of new and cost-effective technologies for the capture of carbon dioxide (CO2) from the existing fleet of coal-fired power plants. \n\n"Currently, the existing U.S. coal fleet accounts for over half of all electricity generated in this country," U.S. Secretary of Energy Samuel W. Bodman said. "The projects announced today will combat climate change and help meet current and future energy needs by curbing CO2 emissions from existing coal-fired plants." \n\n

    PKE is the new range of ECO Coils&Coolers branded air condensers launched by Luvata for commercial AC and refrigeration applications. It is the enhanced offspring of the PCE range (currently phasing out), with improved efficiency and optimized sound emission parameters. Like all ECO Coils&Coolers ventilated units, even the PKE range is available for CO2 applications. The PKE offers an improved hauling and fastening system, thanks to new features. Moreover, the side panels are removable allowing easy access to the units' internal compartments, which have been increased by 120 mm. In order to facilitate maintenance and service, the PKE range has also been equipped with special door holders with a hold open feature. For models with 4 and 5 fan motors, the number of doors has been reduced and the width has been increased, as to allow easy access to the internal components. Lastly, the base has been reinforced for particularly difficult installations. On the other hand, thanks to a compartment incorporated with the condenser to enclose the compressing and the electrical control units, called housing, the PKE range does not require long connection pipe-work, thus reducing the risk of possible leaks. The special internal surface of the compressor compartment has been designed so as to increase sound absorption, reveals the company's press release.

    LONDON, UK, August 12, 2008. Analyst New Energy Finance says the days of easy carbon trading may be over as the low hanging fruit of the cheap carbon credits in the developing world have now been harvested. To date, the cheapest way of reducing greenhouse gas (GHG) emissions have come from projects eliminating high global warming potential (GWP) gases in developing countries, notably China. These projects involve the destruction of two waste gases from industrial facilities: the hydrofluorocarbon HFC-23 and nitrous dioxide, or 'laughing gas' (N2O), both of which are several thousand times more potent in terms of global warming that CO2. The size of the emissions reductions achievable from these projects relative to the scale of the investment required, that these carbon credits are so cheap - around €1/tCO2e. In comparison, costs claimed by project developers of renewable energy and energy efficiency projects are €5-15 per tonne and the global market price for carbon countries from developing countries are around €20/tCO2e.

    Generally speaking, richer nations want permit allotments that track historic emissions rates - essentially locking in their economic advantage by awarding permits based on how much a country is already emitting. Developing countries, in contrast, want permits allocated according to population size, with every person on the planet getting equal emissions rights.

  • here is just one problem. How did these delegates, from around the world, get to the conference? For the most part, they flew over land and sea in airplanes. Airplanes are known to be one of the bigger offenders of CO2 emissions. The UN Intergovernmental Panel on Climate Change estimates that air travel causes 3.5 percent of global warming. This could increase to 15 percent by 2050.When landed, some potentates traveled by gas-guzzling limousine.

    The electricity sector accounts for almost 35 percent of greenhouse gas (GHG) emissions in the United States, and 40 percent of the carbon dioxide (CO2) emissions. Over 80 percent of GHG emissions associated with electricity generation are from the combustion of coal, with nearly all the rest due to natural gas and petroleum combustion. U.S. electricity sales are split among the residential (37 percent), commercial (36 percent), and industrial (27 percent) sectors, where primary uses vary by sector. Over the past 30 years the U.S. electricity sector has become less carbon intensive, and the U.S. economy has grown less electricity-intensive.

    "What are the most important key performance indicators? There are, for example, indicators defining the temperature changes in reference rooms. This includes what is referred to as hours of overheating in summer. If the room temperature exceeds 26 degrees Celsius during more than 10 percent of the hours of use during a year, the room comfort is no longer achieved. Other indicators measure air quality. For example, there are CO2 sensors or so-called VOC-sensors that detect certain scents emitted by the users themselves. If the data exceed certain values, the performance in terms of air quality is not considered as good. In addition, there are energy performance indicators, such as an indicator for the overall energy efficiency of a building. We simply measure the energy that is supplied to the building. We then compare the data to pre-calculated values. We can then evaluate whether the building achieves the desired energy performance. Another indicator is the so-called net energy consumption. This is the energy that users actually have to pay for. "

    Prysmian Group, the industry leading cable and systems provider, won a contract worth a record-breaking €800M for the development of a high voltage DC submarine power transmission link between Scotland and England. The project will involve the use of at least 400km of a new Prysmian-developed cable product called Mass Impregnated PPL cables, which utilises new material technology to operate with a record longhaul wiring voltage rating of 600kV. This means that energy losses will be kept to a minimum, resulting in a low CO2 footprint for the supply of Scotland-sourced renewable energy for England and vice-versa (the link will be bidirectional). Commissioning is expected in late 2015.

The end of Bretton Woods 2? - 0 views

2008-crisis economics

  • The Bretton Woods 2 system – where China and then the oil-exporters provided (subsidized) financing to the US to sustain their exports – will come close to ending, at least temporarily. If the US and Europe are not importing much, the rest of the world won’t be exporting much.
  • And rather than ending with a whimper, Bretton Woods 2 may end with a bang. In some sense Bretton Woods 2 has been on life support for a while now. China’s recent export growth has depended far more on Europe than on the US. US demand for non-oil imports peaked in 2006. One irony of the past year is that the US was borrowing far more from China that it was buying from China. Campaign rhetoric that the US was paying for Saudi oil with funds borrowed from China isn’t far off – though it leaves out the fact that the US also borrows from Saudi Arabia to pay for Venezuelan, Mexican and Nigerian oil.
  • If Bretton Woods 2 ends in 2009 – if US demand for imports falls sharply in the last part of 2008 and early 2009, bringing the US trade deficit down – it won’t have ended in the way Nouriel and I outlined back in late 2004 and early 2005. We postulated that foreign demand for US debt would dry up – pushing up US Treasury rates and delivering a nasty shock to a housing-centric economy. As Brad DeLong notes, it didn’t quite play out that way. The US and European banking system collapsed before the balance of financial terror collapsed. Dr. DeLong writes: All of us from Lawrence Summers to John Taylor were expecting a very different financial crisis. We were expecting the ‘Balance of Financial Terror’ between Asia and America to collapse and produce chaos. We are not having that financial crisis. Instead we are having a very different financial crisis. Catastrophic failures of risk management throughout the entire banking sector caused a relatively minor collapse in housing prices to freeze up global finance to a degree that has not been seen since the Great Depression. The end result of this crisis though could be rather similar: a sharp contraction in credit, a fall in US economic activity, a fall in US imports and a fall in the amount of foreign financing the US needs.* The US government is (possibly) trying to offset the fall in private demand by borrowing more and spending more — but as of now there is realistic risk that the fall in private activity will trump the fiscal stimulus.

  • Or, to put it more succinctly, Bretton Woods 2, as it evolved, hinged both on the willingness of foreign central banks to take the currency risk associated with lending to the US at low rates in dollars despite the United States large current account deficit AND the willingness of private financial intermediaries to take the credit risk associated with lending at low rates to highly-indebted US households.
  • But now US financial institutions are neither willing nor able to take on the risk of lending even more to US households. For a while the US government was able to ramp up its lending to households (notably through the Agencies) and in the process effectively take over the function previously performed by the private financial system (over the last four quarters, the flow of funds data indicates that the Agencies provided around $800 billion of net credit to US households). But now the US government is struggling to keep the financial system from collapsing. It doesn’t seem like it will able to avoid a sharp fall in the overall availability of credit.
  • It is now clear how the financial sector kept profits up: it took on more risk, as it shifted from borrowing short to buy safe long-term assets (Treasuries and Agencies) to borrowing short to buy risky long-term assets. Leverage in the system also increased (and for some broker dealers that seems to be an understatement), as more and more financial institutions believed that the US had entered into an era of little macroeconomic or financial volatility. The net result seems to have been a truly explosive concentration of risk in the hands of a core set of financial intermediaries in the US and Europe. Securitization – it seems – actually didn’t disperse risk into the hands of institutions able to handle it.
  • I hope that the process of adjustment now underway isn’t as sharp as I fear. The US economy gradually can shift from producing MBS for sale to US investors flush with cash from the sale of safe securities to China and Saudi Arabia to producing goods and services for export – but it cannot shift from churning out complex debt securities to producing goods and services overnight. Indeed, in a slowing US and global economy, improvements in the US deficit will likely come from faster falls in US imports than in US exports – not from ongoing growth in US exports.
  • But right now it looks like there is a real risk that the adjustment won’t be gradual. And it certainly looks like the flow of Chinese (and Gulf) savings to US households over the past few years has produced one of the largest misallocations of global capital in recent history.
  • US taxpayers are going to be hit with a large tab for the credit risk taken on by undercapitalized financial intermediaries. Chinese taxpayers may get hit with a similar tab for the losses their central bank incurred by overpaying for US and European assets as part of its policy of holding its exchange rate down. The TARP is around 5% of US GDP. There are plausible estimates that China’s currency losses will prove to be of comparable magnitude. Charles Dumas puts the cost at above 5% of GDP: “Charles Dumas of Lombard Street Research estimates that China makes 1-2 per cent on its (largely) dollar reserves. It then loses up to 10 per cent on the exchange rate and suffers a Chinese inflation rate of 6 per cent for a total real return in renminbi of about minus 15 per cent. That is a loss of $270bn a year, or a stunning 7-8 per cent of gross domestic product.”
  • Jboss — if some of the Chinese inflow could be redirected into investment in alternative energy, that would indeed be a win/ win. Some infrastructure bank style ideas have promise in my view — basically, the flow that used to go to freddie/ fannie could go to wind farms and the like. I would rather see more adjustment in china (i.e. more investment in Chinese infrastructure) but during the transition, if there is one, to a lower Chinese surplus, redirecting chinese financing toward new energy tech would be offer real benefits.
  • China likes 3rd generation nuclear power. Safe, lower cost than NG or coal, very much lower cost than coal with carbon sequestering, and zero carbon footprint. Wind is about 4X more expensive than our electric costs now. That’s in an area with consistent wind. Solar is worse. I don’t know if we can sucker them into investing in our technical fairy tales. Here’s a easy primer on 3rd gen nukes. http://nuclearinfo.net/Nuclearpower/WebHomeCostOfNuclearPower

      is this true?
  • btw, solar thermal installations are so easy & affordable to retrofit onto existing structures, it’s amazing that there aren’t more of them here…until you realize that they work to decentralize energy. cedric — china is already doing it in china. they are way ahead of the curve over there. my partner brought back some photos of shanghai — rows of middle class homes each with a small solar panel on top. and that’s just the tip of the iceberg — an architect friend just came back from beijing and wants to move to china (he’s into designing self-powering structures and is incredibly frustrated by the bureaucracy and cost-prohibitive measures in the US).
  • I went to engineering school right after the Arab Oil Embargo, and alternative energy was a hot topic then. All the same stuff you hear of nowadays. They even offered entire courses on it , which I took. Then my first mini career was in the power plant biz, before Volker killed it with interest rates and the Saudies killed any interest in alt. energy with their big oil field discovery. For the last 5 years I’ve been researching what’s changed, and it is frighteningly little. Solar cells are still expensive and only have a 15% conversion efficiency. They developed the new cost reduced film technology, but that knocks down efficiency to 7%. Wind power works where there is wind constantly. Generators are mature technology and are already 90 some percent efficient. Geothermal, tidal, ect. work where they are available. Looks like coal gasification and synfuel is out because it makes too much CO2. Good news is 3rd gen nuclear is way better than 1st gen plants. Hybrid cars are good, and battery technology is finally getting barely good enough for all electric cars to be practical.
  • According to news report today, Japan’s trade surplus is less than 1 billion $ in September 08, a whopping 94% decrease compared to September 07. Does it imply that going forward Japan can not buy as much treasury as before?
