[RUSSIA] Investors Bet Millions on the Sun

The image of Russia as a dark northern country that lives off its fossil fuels might be well-founded. But companies that rely on global demand for solar energy and Russia's scientific base have investors convinced.

The next step: convincing their own government.

Nitol Solar, a private company in the east Siberian town of Usolye-Sibirskoye, has raised $600 million in investment since opening five years ago, including $190 million from Alfa Bank on Aug. 12 and $75 million from the World Bank's International Finance Corporation in late July.

The latest investment agreements were signed after Nitol Solar produced its first batch of polysilicon, an energy-intensive raw material that is the main component of solar cells.

Nitol Solar's production of polysilicon was big news in the solar power market, which currently provides about 1 percent of global energy consumption and has been growing rapidly in the past couple of years, fueled by rising energy costs and environmental awareness. The main reason the market is not expanding more quickly is a shortage of polysilicon, which absorbs the sun's photons in order to generate an electric current.

Nitol Solar, based in a restructured Soviet chemical plant in the Irkutsk region, plans to produce 3,700 tons of polysilicon per year, or about 9 percent of last year's global supply, by the end of 2009.

These plans have attracted big players like Chinese solar power holding Suntech Power, the world's third-biggest producer of solar cells with a market capitalization of $6.3 billion. Suntech has signed a seven-year supply agreement with Nitol and has agreed to purchase $100 million worth of newly issued ordinary shares in the Russian company.

In addition to China, Nitol Solar supplies raw materials for solar cell production to several European countries, the United States, Japan, Taiwan and South Korea, with total contracts worth of $1.5 billion through 2015, said executive director Dmitry Kotenko.

The company currently has no long-term contracts with Russian solar panel manufacturers. But industry players and investors expect that to change.

Kotenko is optimistic that a government drive to promote innovative technologies will jump-start the solar power industry. "The photovoltaic industry is technologically and scientifically intensive. In this regard, Russia can take advantage of its general scientific potential while developing such innovative industry sector," he said.

Alfa Bank vice president Veniamin Gutnikov echoed Kotenko's hopes. "We expect the solar power market to develop in Russia in the next four years and anticipate an introduction of subsidies and reduced taxes for companies in the sector," he said.

Solar manufacturers in Europe and the United States enjoy similar perks already.

President Dmitry Medvedev signed a decree in early June that ordered the government to "consider supporting and stimulating renewable energy projects" from the federal budget starting in 2009.

Energy Ministry spokesman Pavel Rodionov could not immediately say Thursday whether any legislation to support alternative energy initiatives was in the works.

Only 0.7 percent of energy production in Russia comes from renewable resources, and the domestic market is expected to grow. Some parts of Siberia and regions in the south of the country get as many as 300 sunny days a year, which is comparable to the amount of sun in southern Europe, where solar panels are increasingly popular, Gutnikov said.

Russia has several solar panel manufacturers, most of which are experiencing shortages of polysilicon. Krasnodar-based Solar Wind, which produces solar modules for Spain, Germany and Greece, has the capacity to produce four times more than it is actually producing because of the raw-material shortage, said company spokesman Timofei Serov. "Demand is so high that we hardly have any storage space -- clients purchase our product immediately," he said.

While solar power in Europe is increasingly replacing conventional power production in urban areas, in Russia solar cells are primarily installed in remote areas to power antennas for cellular phones and security systems, Serov said. In recent years, the share of Solar Wind's Russian clients has grown from 5 to 20 percent, he said.

Using alternative energy such as solar cells makes economic sense in regions that spend a lot of money to ship in energy, said Igor Podgorny, head of Greenpeace's energy efficiency program. Last year, the northern republic of Sakha paid 1.2 billion rubles to transport fossil fuel, according to Greenpeace data.

"It's hard for new players to come into Russia's energy sector," Podgorny said.

Equipping a dacha with solar panels is still relatively costly, while companies have shown little interest in using innovative alternative technology for industrial facilities and power plants, he said.

As a result, conventional energy production is chosen even when it may not make economic sense. When it was decided to replace the polluting diesel-powered electric station on Olkhon Island in Lake Baikal, the authorities chose a complex system of power lines and underwater cables that stretched to the island from the shore. "That project was so complex that it will only pay for itself in 70 years, which is extremely high for the energy industry," Podgorny said.

Cheaper alternatives based on solar and wind power were proposed, but they did not get approved, he said.

Worldwide, solar power is taking off. Last year, the amount of energy produced by solar cells shot up 51 percent to 3,733 megawatts, while installations of solar cells have increased fivefold in the past five years, according to the Worldwatch Institute. The solar cell industry raised $10 billion and generated $17.2 billion in global revenues in 2007, according to an industry report by Solarbuzz.

The International Energy Agency has predicted that solar power production will grow 60-fold worldwide between 2004 and 2030.

Kotenko of Nitol Solar said tax breaks and other perks could help Russia's solar power sector, but he expressed optimism that the industry breakthrough would eventually come because of market forces. "Market conditions will make solar power competitive with traditional energy because prices for traditional energy are growing while improving photovoltaic technology is lowering prices for solar," he said.

"The solar power sector is growing exponentially. It's one of the most dynamic industries worldwide," he added.

Solar Wind also has ambitious expansion plans. "The polysilicon shortage is a resolvable issue, so we plan to increase our capacity from 8 peak kilowatt per year to 150 peak kilowatt per year in 2012," Serov said. "We already have an investor, and work is under way."

NEW TECH: SkyFarming

The next is a cool report, from New York Magazine. Some people could think their are only freaky ideas and, Sure ... Are only freaky ideas.

The only solution to get a clean development is throgh serious policy from the Goverment together with enterprises and investigation institutes, so is nice to read the several proposes around the world. You have one Here, ¨The Sky Farming ¨.

What´s is the opinion from the DOE ?
atte. iMAT

USA: SkyFarming
by Lisa Chamberlain (NYMag)
A Columbia professor believes that converting skyscrapers into crop farms could help reduce global warming and make New York cleaner. It’s a vision straight out of Futurama—but here’s how it might work.

Urban farming has always been a slightly quixotic endeavor. From the small animal farm that was perched on the roof of the Upper West Side’s Ansonia apartment building in the early 1900s (fresh eggs delivered by bellhop!) to community gardens threatened by real-estate development, the dream of preserving a little of the country in the city is a utopian one. But nobody has ever dreamed as big as Dr. Dickson Despommier, a professor of environmental sciences and microbiology at Columbia University, who believes that “vertical farm” skyscrapers could help fight global warming.

Imagine a cluster of 30-story towers on Governors Island or in Hudson Yards producing fruit, vegetables, and grains while also generating clean energy and purifying wastewater. Roughly 150 such buildings, Despommier estimates, could feed the entire city of New York for a year. Using current green building systems, a vertical farm could be self-sustaining and even produce a net output of clean water and energy.

Despommier began developing the vertical-farming concept six years ago (his research can be found at verticalfarm .com), and he has been contacted by scientists and venture capitalists from the Netherlands to Dubai who are interested in establishing a Center for Urban Sustainable Agriculture, either independently or within Columbia. He estimates it could take a working group of agricultural economists, architects, engineers, agronomists, and urban planners five to ten years to figure out how to marry high-tech agricultural practices with the latest sustainable building technology.

What does this have to do with climate change? The professor believes that only by allowing significant portions of the Earth’s farmland to return to forest do we have a real chance of stabilizing climate and weather patterns. Merely reducing energy consumption—the centerpiece of the proposal Al Gore recently presented to Congress—will at best slow global warming. Allowing forests to regrow where crops are now cultivated, he believes, would reduce carbon dioxide in the atmosphere as least as much as more-efficient energy consumption.

There is another reason to develop indoor farming: exploding population growth. By 2050, demographers estimate there will be an additional 3 billion people (a global total of 9.2 billion). If current farming practices are maintained, extra landmass as large as Brazil would have to be cultivated to feed them. Yet nearly all the land that can produce food is already being farmed—even without accounting for the possibility of losing more to rising sea levels and climate change (which could turn arable land into dust bowls).

Depending on the crops being grown, a single vertical farm could allow thousands of farmland acres to be permanently reforested. For the moment, these calculations remain highly speculative, but a real-life example offers a clue: After a strawberry farm in Florida was wiped out by Hurricane Andrew, the owners built a hydroponic farm. By growing strawberries indoors and stacking layers on top of each other, they now produce on one acre of land what used to require 30 acres.

Why build vertical farms in cities? Growing crops in a controlled environment has benefits: no animals to transfer disease through untreated waste; no massive crop failures as a result of weather-related disasters; less likelihood of genetically modified “rogue” strains entering the “natural” plant world. All food could be grown organically, without herbicides, pesticides, or fertilizers, eliminating agricultural runoff. And 80 percent of the world’s population will be living in urban areas by 2050. Cities already have the density and infrastructure needed to support vertical farms, and super-green skyscrapers could supply not just food but energy, creating a truly self-sustaining environment.

Like the Biosphere 2 project in Arizona, a real vertical farm will probably require a utopian philanthropist with deep pockets. In the eighties, Edward Bass spent $200 million of his own money to construct the Biosphere. A smaller and less complex vertical farm would probably cost that much to build today and could be funded by someone from a country where arable land is already in short supply, such as Japan, Iceland, or more likely Dubai. Despommier is convinced the first vertical farm will exist within fifteen years—and the irony is, oil money could very well build it.

1. The Solar Panel
Most of the vertical farm’s energy is supplied by the pellet power system (see over). This solar panel rotates to follow the sun and would drive the interior cooling system, which is used most when the sun’s heat is greatest.

2. The Wind Spire
An alternative (or a complement) to solar power, conceived by an engineering professor at Cleveland State University. Conventional windmills are too large for cities; the wind spire uses small blades to turn air upward, like a screw.

3. The Glass Panels
A clear coating of titanium oxide collects pollutants and prevents rain from beading; the rain slides down the glass, maximizing light and cleaning the pollutants. Troughs collect runoff for filtration.

4. The Control Room
The vertical-farm environment is regulated from here, allowing for year-round, 24-hour crop cultivation.

5. The Architecture
Inspired by the Capitol Records building in Hollywood. Circular design uses space most efficiently and allows maximum light into the center. Modular floors stack like poker chips for flexibility.

6. The Crops
The vertical farm could grow fruits, vegetables, grains, and even fish, poultry, and pigs. Enough, Despommier estimates, to feed 50,000 people annually.

The vertical farm doesn’t just grow crops indoors; it also generates its own power from waste and cleans up sewage water.


1. The Evapotranspiration Recovery System
Nestled inside the ceiling of each floor, its pipes collect moisture, which can be bottled and sold.

2. The Pipes
Work much like a cold bottle of Coke that “sweats” on a hot day: Super-cool fluid attracts plant water vapors, which are then collected as they drip off (similar systems are in use on a small scale). Despommier estimates that one vertical farm could capture 60 million gallons of water a year.

3. Black-Water Treatment System
Wastewater taken from the city’s sewage system is treated through a series of filters, then sterilized, yielding gray water—which is not drinkable but can be used for irrigation. (Currently, the city throws 1.4 billion gallons of treated wastewater into the rivers each day.) The Solaire building in Battery Park City already uses a system like this.


4. The Crop Picker
Monitors fruits and vegetables with an electronic eye. Current technology, called a Reflectometer, uses color detection to test ripeness.

5. The Field
Maximization of space is critical, so in this rendering there are two layers of crops (and some hanging tomatoes). If small crops are planted, there might be up to ten layers per floor.

6. The Pool
Runoff from irrigation is collected here and piped to a filtration system.

7. The Feeder
Like an ink-jet printer, this dual-purpose mechanism directs programmed amounts of water and light to individual crops.


8. The Pellet Power System
Another source of power for the vertical farm, it turns nonedible plant matter (like corn husks, for example) into fuel. Could also process waste from New York’s 18,000 restaurants.

9 to 11. The Pellets
Plant waste is processed into powder (9), then condensed into clean-burning fuel pellets (10), which become steam power (11). At least 60 pellet mills in North America already produce more than 600,000 tons of fuel annually, and a 3,400-square-foot house in Idaho uses pellets to generate its own electricity.

CANADA: Bioenergy eyes P.E.I.

by Andy Walker

As the price of fossil fuels continues to rise, Bruce McCallum says bioenergy is becoming a more attractive option as an energy source throughout the Maritimes.

Mr. McCallum is chairman of the Canadian Bioenergy Association, a national non-profit organization promoting the production of biomass for fuel, heat and power. A bioenergy consultant, he was also chairman of a meeting held in the P.E.I. capital Thursday to explore bioenergy options for heat and power.

A Calgary-based company, New Phase Power, is considering establishing a plant in Borden-Carleton. Mr. McCallum, who is also chairman of the Maritime Bioenergy Working Group that has developed sustainable harvesting guidelines for the region, said there are also proposals for other plants throughout the region, including one in Port Hawkesbury.

"Obviously at $20 a barrel for oil, the economics for biomass simply don’t add up," Mr. McCallum said in an interview. "However, my own view is oil is going to be closer to $100 than $20 for some time to come."

He said the developers of the biomass proposals must receive in the range of 10-12 cents a kilowatt when they sell their product to the respective provincial utility for distribution to the consumer. The association president added "that is the figure that is being used for several biomass proposals in Ontario, and it has to be close to that in the Maritimes for this to work."

If the economics can be worked out, he said there will be a new market for low-grade softwood, much of which is now considered a waste product. However, he added it is vital the product be harvested in a sustainable manner.

To that end, the Maritime Bioenergy Marketing Group has developed some basic harvesting guidelines.

"We have to focus biomass harvesting on stem material and large tops," said Mr. McCallum. "We have to leave the branches that have fallen on the forest floor as nutrients for future stands."

As well, he added clearcutting should be avoided and care must be taken to minimize disturbance to forest wildlife.

New Phase Power is negotiating with the province and Maritime Electric, trying to nail down those economic details Mr. McCallum talked about.

Energy Minister Jamie Ballem told the conference he is hopeful the talks will see a successful conclusion in the near future.

"This is a perfect fit with our efforts to move away from fossil fuels and power that is generated outside the province," Mr. Ballem said.

"We see it as another step towards our goal of having 30 per cent of our energy from sustainable sources by 2016."

The fabrication yard, which was used to build many of the major components of Confederation Bridge, has been vacant since the bridge was completed in 1997. Mr. Ballem said the New Phase proposal calls for the construction of a 25-megawatt biomass generating plant on the site. A plant of that size could produce enough energy to power 7,500 homes.

Mr. Ballem added the Island forestry industry may not be able to meet the demand for raw materials, and some waste wood may have to be shipped to the province from other parts of the Maritimes.

The minister said one of the major reasons the company is looking at Borden-Carleton is its deepwater port for shipping in raw materials.

UE: política energética y sostenibilidad ambientallas nuevas prioridades

by Andrea Lagna

Europa se hace portavoz de una nueva estrategia energética, dando un amplio espacio a la sostenibilidad ambiental y poniéndose en primera línea en la lucha contra el calentamiento global. El objetivo clave es la reducción drástica de las emisiones de gases de efecto invernadero, gracias a una reducción de la dependencia de los hidrocarburos.Este ambicioso programa lleva consigo una serie de implicaciones políticas, industriales y financiarías.


El eje Berlín-Londres y el nuevo curso de la política energética europea

A estas alturas es innegable que el cambio climático se encuentra en el centro de la agenda política de Angela Merkel, que además ocupa la presidencia de turno en el Consejo de la Unión Europea y en el G8. El principal partner en este reto es el primer ministro inglés Tony Blair, que habla de un giro radical y decisivo a la hora de involucrar más a las principales potencias mundiales alrededor del problema del calentamiento global.

El reciente Consejo de los jefes de Estado y de Gobierno de la Unión Europea (Bruxelles, 8-9 de Marzo) ha promovido y, finalmente, alcanzado un acuerdo vinculante entre los 27 estados miembros sobre la reducción de las emisiones de CO2 y el incremento de las energías renovables. Los cortes en las emisiones serán del 20% respecto a los niveles de 1990, y el uso de fuentes renovables deberá alcanzar el 20% respecto al actual 7%. Con esta situación el elemento más importante será el burden sharing, o sea, la repartición de este 20% comunitario en 27 sub-objetivos nacionales (negociación que se tendrá entre la Comisión Europea y algún estado miembro).La nueva estrategia energética europea, fortalecida ante la toma de conciencia de la actual situación ambiental, se encuadra en el ámbito del European Climate Change Program (ECCP, 2000, puesto al día en 2005). El objetivo principal del ECCP es el de identificar y desarrollar todos los elementos necesarios útiles para implementar el protocolo de Kyoto en el ámbito de una estrategia europea (véase con este propósito el European Union Emission Trading Scheme).

El ECCP, por lo tanto, reúne a los Gobiernos europeos, a los stakeholders y también a los representantes de los mayores grupos industriales y ambientalistas. Son dos las temáticas generales a partir de las que nace y se desarrolla la nueva estrategia energética europea:·

Cambio climático·
Sistema económico de bajo uso de carbón fósil (low-carbon economy)
El cambio climático hace referencia a la variación en el tiempo del clima terrestre (que se mide sobre una escala global o macro-regional, a intervalos expresados en decenas y hasta millones de años). Las causas de la mutación climática se localizan en los procesos internos del ecosistema terrestre, en las fuerzas exógenas como la intensidad de la luz solar, y para terminar, en la actividad humana y en la excesiva producción de gases invernadero (sobre todo CO2 procedente de la combustión de fuentes energéticas agotables, como el petróleo, carbón, gas natural, que a diferencia de las renovables, se regeneran a lo largo de miles de años). Este último es el aspecto sobre el que se centra la atención de las actuales políticas energéticas y ambientales. La opinión compartida de la comunidad internacional es que el cambio climático presenta consecuencias dramáticas para la Tierra, revelando futuros escenarios insostenibles.

El principal organismo propuesto para el estudio de esta cuestión es el Intergovernamental Panelon Climate Change (IPCC), estructura fundada en 1988 dentro del United Nations Framework Convention on Climate Change (UNFCCC).Según la Unión Europea (véase la European Strategy for Sustainable, Competitive and Secure Energy, del 8 de Marzo del 2006, y el Energy for a Changing World, del 10 de Enero de 2007), el futuro energético europeo está orientado hacia una economía de bajo consumo de carbón fósil. Estos son los parámetros principales:· Un corte de al menos del 20% de las emisiones de CO2 antes del 2020 (cifra que subiría al 30% si otras potencias mundiales se sometieran a un régimen de sostenibilidad ambiental, sobre todo USA y China)·

Una propuesta de un acuerdo internacional reforzando el Protocolo de Kyoto·

La utilización de biocarburantes por un mínimo del 10% sobre el consumo total hasta 2020.·

Mejora de las relaciones con los principales partners energéticos·

Desarrollo de un plan estratégico para la investigación y el desarrollo de tecnología eco-compatible (energía renovable, construcciones con ahorro energético, yacimientos nucleares de 4ª generación, etc.)· Un partnershipentre África y Europa para el desarrollo de energías low-carbon en el continente africanoMientras el debate continúa (el gobierno inglés y alemán especulan sobre los respectivos programas de ahorro energético), no hay duda de que la transición hacia un sistema económico basado en la baja utilización de carbón fósil tendrá un impacto importante (pero todavía no está suficientemente valorado) sobre la economía y las relaciones internacionales.

Implicaciones de la nueva estrategia.

El “giro verde” de la Unión Europea presenta importantes implicaciones para la política mundial y para las relaciones inter-europeas.El Consejo de Bruselas ha evidenciado una brecha dentro de la UE. El eje Berlin-Londres es firme en susposiciones en materia ambiental expresadas por la Canciller alemana Angela Merkel. Sin embargo, una línea opuesta ha reagrupado las posiciones de Francia y Polonia (además de la República Checa y Eslovaquia), que han manifestado posiciones diferentes como consecuencia de los respectivos intereses nacionales (sobre todo Francia sobre la cuestión nuclear).

Esto ha supuesto algunas revisiones que han dado a Paris, en medio de un ambiente de protestas por parte de Austria e Irlanda, la posibilidad de usar la energía nuclear como contribución sustancial para la reducción de CO2 (con este propósito la cuestión de los residuos procedentes de las centrales nucleares se queda en el aire).

El carácter vinculante del reciente acuerdo contribuye a proyectar la imagen de una Europa potente en las estrategias energéticas del futuro. Sin embargo, son muchas las cuestiones todavía sin tratar, sobre todo las dificultades a las que hará frente la nueva estrategia (costes efectivos, diferentes necesidades nacionales, restructuración de los sectores, etc.). En pocas palabras, ahora que los objetivos ambientales se han fijado en líneas generales, es necesario entrar en la parte específica de la cuestión, sobre todo desarrollando resultados concretos y efectivos sobre el plano práctico. La mayor dificultad en este sentido se encuentra ala hora de combinar eficiencia económica en términos de competitividad sobre el mercado global, con los nuevos parámetros ecológicos. Con este propósito es importante subrayar, dejando de lado el debate ético sobre la sostenibilidad ambiental, la forma en la que una estrategia de reducción de las emisiones de gases invernadero debe desarrollarse al mismo tiempo que una política económica atenta y equilibrada (sobre todo a nivel internacional).

Obviamente Europa deberá enfrentarse en el escenario mundial. Está muy generalizada la opinión de que habrá un aumento efectivo de los consumos energéticos, y de que sobre todo las fuentes fósiles asumirán un mayor incremento de su uso a causa de las ventajas todavía evidentes que las hacen más competitivas (transporte más sencillo, tecnología de uso madura). Sin embargo, una presunta escasez de los recursos (véase el debate sobre el llamado oil peak), y sobre todo regímenes internacionales de baja emisión de CO2, podrán representar un bloqueo eficaz en el uso de estas fuentes. La demanda energética no satisfecha de los hidrocarburos, por lo tanto, concederá un espacio a las fuentes renovables, dando al sector una concentración alta de inversiones. Aun así, existen dos complicaciones todavía más importantes.La primera dificultad es intrínseca a la naturaleza de las fuentes renovables y a la investigación y desarrollo que será empleado con este propósito.

De todas formas, es necesario tener presente que las fuentes renovables (biomasas, hidroeléctrico, geotérmico, eólico, solar) están caracterizadas por una densidad energética baja, una tecnología en estado de desarrollo, y por lo tanto no representan todavía un aspecto definido entre la opinión pública.La segunda dificultad es relativa al contexto mundial y a la geopolítica de los recursos energéticos. Con este propósito será fundamental el uso de la diplomacia europea y las ventajas absolutas y relativas que los distintos actores (sobre todo USA, China y Rusia) obtendrán tras participar en un régimen ecológico internacional (por ejemplo las futuras implementaciones del Kyoto Protocol to the United Nations Framework Convention on Climate Change)

Conclusiones

Europa está intentando imponer un nuevo giro a la política mundial mirando a la sostenibilidad ambiental y a la economía del conocimiento, un acercamiento multilateral a la seguridad global. Mientras la opinión común concede una importancia especial al aspecto ético-nacional de la cuestión, hay que reconducir los movimientos europeos (principalmente de Berlín y Londres) a un plano pragmático.La estrategia energética europea tiene frente a sí la obligación, impuesta por las tendencias geopolíticas, de diversificar sus propias fuentes de abastecimiento. El empeño moral y la toma de conciencia ambiental aparecen como un terreno fértil sobre el que es posible llevar a las grandes potencias al enfrentamiento y al diálogo mundial. Un refuerzo del Protocolo de Kyoto (y quizás la participación de USA y China) representaría un éxito importante para la democracia europea. Para esto es necesario controlar constantemente la cuestión, sobre todo con vistas a la próxima cumbre del G8 prevista para el próximo mes de Mayo.Las dificultades a las que se enfrenta Europa son muchas, ya sea sobre el plano interno (costes efectivos del “giro verde”, diferentes exigencias nacionales, cuestiones de la liberación del mercado energético, etc.), que a nivel internacional (desenganche del monopolio Gazprom- Rusia). Lo que parece intuirse es el tentativo europeo de empujar la política mundial a medio plazo hacia la formación de un régimen internacional ampliamente compartido, mediante el que gestionar las dinámicas ambientales. No está claro todavía si la UE posee las capacidades materiales reales para desarrollar este régimen .

Intel, comprometido con el desarrollo sostenible

El fabricante de chips logrará ahorros de consumo del 40 por ciento, con un incremento del rendimiento de los centros de datos del mismo rango. La virtualización y su tecnología de microprocesadores de 45 nm son sus pilares para conseguirlo

Click here to find out more!

La ha presentado en Londres una serie de estrategias orientadas a lograr una mayor eficiencia energética, basada en unos centros de datos ecológicos que proporcionan más rendimiento con un menor consumo eléctrico.

Combinando el mayor lanzamiento de su historia, basado en las tecnologías multinúcleo y soportado por la virtualización a gran escala, los CIOs tendrán la oportunidad de incrementar el rendimiento de sus centros de datos de alta densidad al mismo tiempo que reducen el consumo y mejoran la eficiencia energética.

La introducción de nuevos materiales en la fabricación de millones de microprocesadores de 45 nanómetros generará ahorros de electricidad de hasta el 40 por ciento, particularmente con el procesador Quad Core Intel Xeon 5300, que supera en 1,5 veces el rendimiento de su predecesor, la serie 5100.

Para Dan Costello, director de la división Standards & Technology de Intel, los propósitos fundamentales de la compañía son aprovechar los recursos globales de virtualización, consolidación y acelerar el proceso de refrigeración de los DC. "La eficiencia energética ya está al alcance de las empresas, con los servidores Blade se ahorra un 25 por ciento en el consumo.

Desde Intel aseguran ser el único fabricante de chips en incorporar la tecnología de la virtualización en todos sus productos, extendiendo esta práctica entre partners y colaboradores. La compañía siempre ha mostrado preocupación por el medio ambiente, ya que fue pionera de la primera iniciativa de eficiencia energética con 'Energy Star'. Asimismo, han diseñado el primer 'edificio verde', que se levantará en Israel teniendo en cuenta cada elemento para causar el menor impacto posible al planeta, desde la construcción del bloque con materiales reciclados y maderas controladas, hasta la gestión personalizada de calor e iluminación.

MEXICO: Necesario, garantizar la eficiencia energética, Semarnat

La primera tarea de México es integrar políticas que garanticen la eficiencia energética y de desarrollo sustentable, porque el cambio climático se ha convertido en un asunto de seguridad mundial que afecta a todos los humanos.

El titular de la Secretaría de Medio Ambiente y Recursos Naturales (Semarnat) , Juan Rafael Elvira Quesada, señaló que el ser humano está enfermando al eslabón más sensible del planeta que es la atmósfera mediante la emisión de millones de toneladas de bióxido de carbono, lo que ha provocado el calentamiento global.

En el caso de México, dijo, las primeras tareas del gobierno federal consisten en integrar con la Secretaría de Energía políticas que garanticen la eficiencia tanto en el sector energético como en materia de desarrollo sustentable.

En un comunicado, dio a conocer que se trabaja de forma coordinada con Petróleos Mexicanos (Pemex) y la Comisión Federal de Electricidad (CFE) en la generación de energías limpias.

Sin embargo, a estos dos pasos, dijo, se deberá sumar la labor legislativa con el fin de establecer incentivos fiscales que faciliten la generación de energías renovables en el país.

El tema del Cambio Climático ya forma parte de la educación de la sociedad mexicana interesada en conocer cada vez más sobre este fenómeno, que es considerado como el reto ambiental más importante del siglo.

Recordó que en la gira de trabajo del presidente Felipe Calderón Hinojosa a Reino Unido se acordó integrar grupos de trabajo, entre científicos y funcionarios de ambos países, con la finalidad de determinar y conocer con precisión los impactos que puede tener el calentamiento global.

De este modo será posible saber la manera en que puede impactar a estados como Veracruz, Tabasco, Yucatán o Sonora; a regiones como las penínsulas de Yucatán y Baja California o la Riviera Maya; y los sectores turístico, agrícola o de pesca.

Elvira Quesada anticipó que en menos de dos meses, el presidente presentará la estrategia que México seguirá para enfrentar el cambio climático, documento que contemplará medidas en materias de adaptación, mitigación y concientización sobre ese problema.

Church Joins the Battle to Save the Planet

When the American architect Richard Meier was asked to design a church in Rome to commemorate the 2,000th anniversary of Christianity, he offered an imposing white concrete structure dominated by three soaring “sails.”

The project’s main technical sponsor got to work on a coating that would enhance Mr. Meier’s trademark white sculptural forms. It came up with a material that essentially cleans itself, minimizing the need for maintenance.

What the sponsor, the Italcementi Group, did not know was that the new material — which contains titanium dioxide, a white pigment — has another peculiarity. It “eats” surrounding smog.

Extensive testing has since determined that construction products containing titanium dioxide help to destroy pollutants found in car exhaust and heating emissions, scientists say.

Several companies are now developing smog-eating products that can be used not only for the facades of buildings but also in paint, plaster and paving materials for roads. The new substances are now being tried in buildings, squares and highways in Europe and Japan.

Hailed by some scientists as a breakthrough, the process is still being evaluated by others. The question, said Melanie L. Sattler, professor of civil and environmental engineering at the University of Texas at Arlington, is “whether coatings on buildings would be able to treat enough of the atmospheric air to make a difference.”

Titanium dioxide had been used in self-cleaning coatings before because of its photocatalytic properties: sunlight sets off a chemical reaction that accelerates natural oxidation. Upon testing its new compound, however, Italcementi realized that the material could also break down nitrogen oxides emitted in the burning of fossil fuels.

“Theoretical work in photocatalysis has been going on since the 1980s,” said Enrico Borgarello, Italcementi’s director of research and development. “The problem is that no one had developed any practical applications.”

According to Italcementi, tests in urban settings determined that some pollutants could be reduced by 20 to 70 percent. The reduction of pollutants is greatest within about eight feet of a surface that has been treated, the company said. This means that a pedestrian on a street with traffic would inhale fewer pollutants while passing treated buildings.

In one test, paving material using photocatalytic cement was used to cover the asphalt surface of a 1,000-foot stretch of road outside Milan with an average traffic flow of 1,000 vehicles an hour. Tests showed a reduction of about 60 percent in nitrogen oxides at street level, according to Italcementi.

Environmental scientists and engineers are following the development with keen interest. “Philosophically, it is better never to form pollutants than to find ways to destroy pollutants, but this is a useful technique for air pollutants that humans already make,” said Dr. Howard Liljestrand, a specialist in environmental chemistry at the University of Texas at Austin.

But he cautioned that the cost efficiency of such products would depend on long-term performance, adding, “Catalysts tend to lose their effectiveness over time.”

Now that Italcementi’s product, TX Active, has gone beyond the testing phase, does it work? Three years after Mr. Meier’s church opened in Tor Tre Teste, in eastern Rome, the bulk of the majestic structure remains remarkably bright, in contrast to the grimy gray joints, which were not treated with the product.

“It’s hard to say if it’s revolutionary,” Mr. Meier said by telephone, “but we’re happy with the results.”
