    "The Chilean government has set its sights on significantly increasing its geothermal energy capacity. The Ministry of Energy recently announced a new contract for the development of 20 areas by 2012. 70 bids from 13 domestic and foreign firms were submitted for the rights to exploit the newly released regions of Rarapacos and Los Ricos. Earlier in the year, Energy Minister Ricardo Raineri announced more than 170 concessions for geothermal energy by 2012. He further specified that these concessions would be supported by US$200 million in funding from the government. The country is striving to increase its geothermal capacity to 1,000 megawatts in order to meet an ever-growing energy demand in a sustainable manner"

  • Donald Sadoway: The missing link to renewable energy
  • What's the key to using alternative energy, like solar and wind? Storage -- so we can have power on tap even when the sun's not out and the wind's not blowing. In this accessible, inspiring talk, Donald Sadoway takes to the blackboard to show us the future of large-scale batteries that store renewable energy. As he says: "We need to think about the problem differently. We need to think big. We need to think cheap." Donald S

This technology seems to me to be much more beneficial on a local scale, what if every home had its own battery, then home power generation becomes economically more viable for everyone. If you could show that a system like this could pay for itself in say 5 years then every home would want one. Plus for this to be implemented on a large scale requires massive investment that could be decades away. Share the technology and lets get it in homes by next year. Great ted talk. Jon Senior 0 Reply 1 hour ago: I agree 100%. Localised energy production would also make energy consumers more conscious of their consumption and encourage efforts to reduce it. We can invent and invent all we want, but the fast solution to allowing renewable energies to take centre stage is to reduce the base energy draw. With lower baseline consumption, smaller "always on" generators are required to keep the grid operational. Town and house-l

    Dwarfed by any of the north African nations, it represents an area slightly smaller than Wales but scientists claimed yesterday it could one day generate enough solar energy to supply all of Europe with clean electricity. Speaking at the Euroscience Open Forum in Barcelona, Arnulf Jaeger-Walden of the European commission's Institute for Energy, said it would require the capture of just 0.3% The scientists are calling for the creation of a series of huge solar farms - producing electricity either through photovoltaic cells, or by concentrating the sun's heat to boil water and drive turbines - as part of a plan to share Europe's renewable energy resources across the continent. A new supergrid, transmitting electricity along high voltage direct current cables would allow countries such as the UK and Denmark ultimately to export wind energy at times of surplus supply, as well as import from other green sources such as geothermal power in Iceland. Energy losses on DC lines are far lower than on the traditional AC ones, which make transmission of energy over long distances uneconomic. The grid proposal, which has won political support from both Nicholas Sarkozy and Gordon Brown, answers the perennial criticism that renewable power will never be economic because the weather is not sufficiently predictable. Its supporters argue that even if the wind is not blowing hard enough in the North Sea, it will be blowing somewhere else in Europe, or the sun will be shining on a solar farm somewhere.

    The solar industry and semiconductor industry are intimately connected. Both industries rely on silicon and both use much of the same processing technology and supply chain to produce their products. Nowhere has this connection been on better display than last week at the Moscone Center in San Francisco California, where the Intersolar North America made its debut in conjunction with SEMICON West 2008. The show provided an opportunity for those in the two industries to connect and allowed those companies that work in both spaces to showcase their collective efforts. According to Chris O'Brien, Head of Market Development and Government Relations for North America for Oerlikon Solar, holding the two conferences together gave companies greater exposure and showed the promise of the U.S. solar market. In recent months a number of traditional semiconductor companies including Intel and National Semiconductor have made announcements that they are making plans to enter the solar industry in one way or another. Intel spun off it's solar research area into a new solar company called SpectraWatt. National Semiconductor announced that it will be introducing it's first solar product, SolarMagic, that could raise the efficiency of residential and industrial solar systems. Kevin Kayser, Senior Marketing Manager at National said that he product will be targeted at installers and integrators and much planning went into the company's decision to enter the solar space. "Photovoltaics currently has less than 1% of the energy market, but we think it has potentially one of the fastest growth rates of any alternative energy source. Now certainly we're looking at wind, we're looking geothermal, we're looking at other sources, but from an electronics point of view we saw that we had the most immediate potential impact in solar photovoltaics," Kayser said.

    The Policy Brief for a Global Green New Deal, developed by economists and the UN ahead of the G-20 meeting of world leaders in London in early April, highlights the benefits of investing a significant amount of the $3 trillion-worth of global stimulus packages in five areas. According to a news release issued by the UN Environment Programme (UNEP), these areas include raising the energy efficiency of old and new buildings, as well as renewable energies including wind, solar, geothermal and biomass.

  • General Electric and Google on Wednesday announced a collaboration to lobby for renewable energy policies and to jointly develop clean technologies.
  • On the technology side, the two companies intend to develop smart-grid technologies, plug-in hybrid vehicles, and enhanced geothermal systems, where underground heat is converted into electricity. Smart-grid technology lets utilities more efficiently manage electricity on the grid. And through smart meters and in-home displays, it lets consumers better understand and control home energy use. GE and Google will work on utility software to make the grid more efficient, and on software for home smart-grid equipment, Immelt said.

The end of Bretton Woods 2? - 0 views

2008-crisis economics

shared by Wade Ren on 29 Oct 08 - Cached
  • 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?
