WESTERN HEMISPHERE: Converting land for biofuel worsens global warming
2008-02-09 23:55:00
Clearing raw land to produce biofuels actually contributes to global warming by emitting large amounts of greenhouse gases into the atmosphere, researchers warned Thursday.Carbon dioxide (CO2) emissions from new croplands carved into rainforests, savannas, wetlands or grasslands would easily surpass the overall amount of CO2 emissions reduced through the use of biofuels, according to a report in the February 8 edition of Science."If you're trying to mitigate global warming, it simply does not make sense to convert land for biofuels production," said Joe Fargione, a founder of private environment protection agency the Nature Conservancy and co-author of the study."All the biofuels we use now cause habitat destruction, either directly or indirectly," he said."Global agriculture is already producing food for six billion people. Producing food-based biofuel, too, will require that still more land be converted to agriculture."Converting land to grow corn, sugar cane or soy beans -- crop...

TECHNOLOGY: Biomechanical. Knee Brace Generates Electricity From Walking
2008-02-08 17:43:00
A new energy-capturing knee brace can generate enough electricity from walking to operate a portable GPS locator, a cell phone, a motorized prosthetic joint or an implanted neurotransmitter, research involving the University of Michigan shows. A report on the device is published in the Feb. 8 issue of the journal Science. Authors include researchers from Simon Fraser University in Canada and the University of Pittsburgh, in addition to U-M.The wearable mechanism works much like regenerative braking charges a battery in some hybrid vehicles, said Arthur Kuo, an associate professor of mechanical engineering at U-M and an author of the paper.Regenerative brakes collect the kinetic energy that would otherwise be dissipated as heat when a car slows down. This knee brace harvests the energy lost when a human brakes the knee after swinging the leg forward to take a step.Kuo, who called the device "a cocktail-napkin idea," says knee joints are uniquely suited for this endeavor."There is pow...

TECHNOLOGY: Screen-Printed Solar Cells
2008-02-08 17:20:00
Members of the Fraunhofer Institute for Solar Energy Systems ISE are traveling to Tokyo with bulky luggage these days. Their destination is Nanotech 2008, the world's largest trade fair for nanotechnology. Their solar module, which they will be presenting in the BMBF marketing campaign 'Nanotech Germany', is the size and shape of a door: two meters high and sixty centimeters wide.The key component of the new modules is an organic dye which in combination with nanoparticles converts sunlight into electricity. Due to the small size of the nanoparticles, the modules are semi-transparent. This aspect makes them well suited for facade integration. The solar module prototype manufactured by the researchers at Fraunhofer ISE is amber in color. It is possible, however, to produce the modules in other colors, or even to print images or text on the module so that it serves as a decorative element.These design options open up an entirely new range of possible applications. Instead of mounti...

UNITED STATES: Bush wants climate deal that gives 'none a free ride'
2008-02-05 03:58:00
US President George W. Bush called Monday for completing an international deal aimed at cutting global-warming greenhouse gases that involves "every major economy and gives none a free ride."In his annual State of the Union speech, Bush plugged a US initiative which stresses uses of nuclear power and technology to trap emissions from coal plants that critics fear will undermine UN-led efforts to fight climate change."To build a future of energy security, we must trust in the creative genius of American researchers and entrepreneurs and empower them to pioneer a new generation of clean energy technology," he said."Our security, our prosperity, and our environment all require reducing our dependence on oil," he told both houses of Congress.He recalled that lawmakers had responded to his call last year to pass laws to cut oil consumption over the next decade and urged them now to "fund new technologies that can generate coal power by capturing carbon emissions."He called for increasing...

EMIRATES: Qatar to build solar power complexes
2008-02-04 00:56:00
Qatar is considering building one of the world's largest solar power complexes to help meet demand, which could increase four-fold over the next 30 years, the Middle East Economic Digest reported.Gulf states have about 30 per cent of the world's oil reserves and 8pc of its gas, but an economic boom spurred by record crude prices is driving demand for power and water so rapidly that many are considering turning to alternative energies including nuclear.Qatar expects to add 16,260mw of power to the national grid between 2011 to 2036, almost four times current capacity of 4,200mw, Qatar General Electricity & Water Corporation senior business development planner Salah Hamza said.The solar complex would have capacity of 3,500mw by 2013, Hamza said.The government of Abu Dhabi is also planning to build a solar power plant as part of its $15 billion proposals to develop green energy. Hamza said the solar complex was part of a wider plan that could include construction of a nuclear pow...

ASIA: China energy law likely to see delay
2008-01-29 05:26:00
China's new energy law has been held back by bureaucratic infighting and is unlikely to be ready in time for the annual session of the national parliament in March, state media reported Friday. The law, which provides the legislative basis for the establishment of a powerful new energy ministry, may not be passed until next year's gathering of the National People's Congress, the China Daily said.Lawmakers are finding it difficult to balance the competing interests involved, the paper said, citing Dong Chaojie, a senior official with the Cabinet's Legislative Affairs Office.China has long argued that it needs a unified bureaucracy to plan, run and supervise its energy sector.Policies and strategies for China's energy sector are currently drawn up by the National Energy Leading Group, a State Council sub-committee set up in 2005 and led by Premier Wen Jiabao.The initial draft of the energy law, released at the beginning of December, called for the establishment of a unified energ...

CLIMATE CHANGE: United Nations Kicks Off Global Warming Conference to Build
2007-12-04 01:58:00
Faced with melting polar ice caps and worsening droughts, climate experts at a massive United Nations conference Monday urged quick action toward a new international pact stemming an increasingly destructive rise in world temperatures.A key goal of the two-week conference, which opened with delegates from nearly 190 countries in attendance, will be to draw a skeptical United States into an agreement to cut emissions of carbon dioxide and other so-called greenhouse gases.While the U.S. delegation declared it would not be a "roadblock" to a new agreement, Washington remains opposed to steps many other countries support, such as mandatory emissions cuts by rich nations and a target for limiting the rise in global temperatures.The American position suffered a blow Monday when the new Australia n prime minister signed papers to ratify the Kyoto Protocol climate pact. The move leaves the U.S. the world's top emitter of greenhouse gases as the sole industrial power not to have joined.Confe...

CO2: Proyecto DECARBit investigará tecnologías de captura de carbono más ec
2007-11-25 01:20:00
Una nueva línea de investigación, financiada con fondos comunitarios, sobre tecnologías de captura de carbono de precombustión para centrales eléctricas de gas y carbón está a punto de ponerse en marcha. La coordinación del proyecto DECARBit, de cuatro años de duración, correrá a cargo de la organización independiente noruega de investigación SINTEF. Financiado con cargo al Séptimo Programa Marco, el proyecto contará con la participación de catorce socios provenientes de ocho países.La tecnología empleada actualmente en la captura de CO2 se basa principalmente en la acción de sustancias químicas capaces de depurar los gases de combustión y separar el CO2 de otros gases en el caudal de escape; es lo que se da en llamar la captura poscombustión. El método resulta más caro y más complicado de dominar que la captura en precombustión, consistente en eliminar el carbono presente en los combustibles a base de carbón y gas natural antes de su llegada a la central eléctrica.La descarbonizaci...

TECHNOLOGY: New technique creates cheap, abundant hydrogen
2007-11-17 06:57:00
US researchers have developed a method of producing hydrogen gas from biodegradable organic material, potentially providing an abundant source of this clean-burning fuel, according to a study released Monday.The technology offers a way to cheaply and efficiently generate hydrogen gas from readily available and renewable biomass such as cellulose or glucose, and could be used for powering vehicles, making fertilizer and treating drinking water.Numerous public transportation systems are moving toward hydrogen-powered engines as an alternative to gasoline, but most hydrogen today is generated from nonrenewable fossil fuels such as natural gas.The method used by engineers at Pennsylvania State University however combines electron-generating bacteria and a small electrical charge in a microbial fuel cell to produce hydrogen gas.Microbial fuel cells work through the action of bacteria which can pass electrons to an anode. The electrons flow from the anode through a wire to the cathode pro...

NEW ZEALAND: Opening of Meridian?s Project West Wind
2007-09-27 23:14:00
Thursday 27 September 2007It's great to be here to turn the first sod of this project and see for myself the site chosen. Indeed when visiting a wind farm site, it generally is very apparent why it was chosen. Makara will have the first wind farm in the Wellington area. At between 140 and 150 megawatts, it will make a substantial contribution to our energy supply, producing enough power to supply Wellington City when the wind is blowing.I opened another of Meridian?s wind farms, White Hill in Southland, in June. At the time, New Zealand was generating 170 megawatts of electricity from wind farms. A few months later, our generation capacity is almost double, at 320 megawatts. With West Wind , our wind generation capacity will significantly increase again.I am told that Meridian expects West Wind to be one of the most productive wind farms in the world. The strong and consistent winds mean Project West Wind will be generating electricity over 90 per cent of the time, and generating at...
