Climate, Energy and Environment News from Latin America: 1.3 - 1.7.2011 | Amanda Maxwel... - 0 views

  • n 2010, thermal energy displaced hydro as the major source of energy generation for the Chilean Central Interconnected System.  Coal, natural gas, and diesel supplied over 50% of energy consumed while hydropower accounted for 48%.  This trend is expected to continue in 2011 if current water shortage conditions persist. (El Mercurio, 1/4/11)  Last year’s drought created a 26% increase in thermal generation as compared to 2009.
  • The Regional Energy Efficiency Strategy initiative led by Bun-ca has reported an energy savings of 9368 MWh over the past six years, equivalent to 4992 tons of carbon dioxide, by working with 190 companies in the industrial and commercial sectors to become more energy efficient.   Recently UNEP’s En.lighten study estimated that Costa Rica could save 276,000 MWh and $27.6 million per year if they changed all light bulbs to CFLs.  The cost of this change was estimated to be $22.63 million.  (El Financiero CR, 1/3/11)
  • The Mexican government is planning to invest four billion dollars to build a one thousand megawatt renewable energy storage facility in Northern Mexico.   The facility will use a special kind of sodium sulfide batteries for the project which is expected to be completed in the next six years.  (Clean Techies, 1/6/11)

Innovations in Industrial Waste Heat Management - 1 views

  • Industrial waste heat management has seen rising levels of importance due to volatile fuel prices and also regulations to maximize energy conservation. As such, industries have started recognizing the necessity and advantages of industrial waste heat management. Till recent past much importance was being paid to recovering waste heat and reusing it as thermal energy. But now the focus is on new methods of waste heat recovery which convert even low grade waste heat into other forms of energy with increased feasibility. Low grade waste heat recovery, which has slowly been gaining prominence is expected to be a major driver for research in the future. This research service report presents analysis on current technology capability and expected future trends in technology adoption for industrial waste heat management. Analytical Hierarchy Process (AHP) was used to evaluate the application potential in the five most energy intensive industries – Cement, Oil and Gas, Steel, Pulp and Paper, and Glass to identify the industry with greatest future application potential. Based on inputs from technology developers and from the predicted market scenario, an evaluation was done.

  • The focus is on high-voltage cables and cable harnesses for high power transmission. These special products are needed because, in cars and commercial vehicles with electric, hybrid or fuel cell drive, 12 volts no longer prevail on their own as they do in conventional vehicles with combustion engines. Instead, electrified powertrains involve voltages up to 1000, which require the cables and components to have special properties with respect to conductivity, mechanical flexibility, thermal capacity and safety

    Thermoelectric bracelet that helps people maintain a comfortable body temperature takes home $10,000 from MIT's annual materials-science design competition. The "watch" part of the prototype actually consists of the team's custom copper-alloy-based heat sink (a component that lowers a device's temperature by dissipating heat). Attached is an automated control system that manages the intensity and duration of the thermal pulses delivered to the heat sink. Integrated thermometers also measure external and body temperature to adjust accordingly.

Spain to Cut Subsidies for Solar PV, not Solar Thermal - 0 views

  •  
    Last week the Spanish government announced plans to cut subsidies for solar photovoltaic (PV) power by about 75%. Although the nation expects to surpass its 2010 goal for installed solar by four fold, the down side is that generous subsidies for the industry have resulted in a ballooning tariff deficit for the country, which has risen to 4.85 billion euros, upfrom 745 million last year. Reuters reported that lending to the Spanish photovoltaic plants has risen to $3.59 billion in the year to day, up from $230.9 million euros last year and $192.44 million in 2006. As a result, the Spanish government will as the energy regulator to cap subsidies for new PV solar capacity at 300 megawatts (MW) per year--200 MW for rooftop systems and 100 MW for ground-mounted systems, which have been the highest growth area. CSP has been slower than PV technology in its emergence on the renewable energy scene, but expectations for the technology, which focuses the heat of the sun to produce steam to drive electricity producing turbines. Projects underway in the U.S. and Spain are expected to produce electricity that is cost-equivalent to electricity produced from burning coal or natural gas.

The end of Bretton Woods 2? - 0 views

  • 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?
