After the Spill
|Ben Geman||November 15th 2012|
BP has reached a $4.5 billion settlement with the U.S. government to resolve criminal and securities claims over a 2010 well blowout that claimed 11 lives and spilled millions of barrels of oil into the Gulf of Mexico.
The British oil giant will pay $4 billion in fines and other payments, the largest criminal penalty in U.S. history, to resolve claims with the Justice Department over the accident that badly harmed Gulf ecosystems and reshaped U.S. offshore drilling policy. The company has also agreed to pay $525 million to the Securities and Exchange Commission to resolve separate claims.
“All of us at BP deeply regret the tragic loss of life caused by the Deepwater Horizon accident as well as the impact of the spill on the Gulf coast region,” said BP CEO Bob Dudley in a statement. U.S. Attorney General Eric Holder and other Justice Department officials have scheduled a 2 p.m. press conference in New Orleans to discuss the settlement. Read more ..
The Race for Wind
|Zack Colman||November 14th 2012|
Sen. Lamar Alexander (R-Tenn.) on Wednesday said the nation’s fiscal situation has become so dire that the government can no longer afford to maintain a wind power production credit that has been in place since in 1992.
“I think there is certainly the largest realization that we’ve ever had that it’s time for it to end,” Alexander said Wednesday at an energy policy breakfast hosted by The Hill and sponsored by the American Energy Alliance.
Alexander is a longtime opponent of the tax incentive, which credits wind power producers 2.2 cents per kilowatt-hour. The credit, which costs about $5 billon per year, is scheduled to expire Dec. 31. Democrats and Republicans from states with significant wind power industries are pushing for its extension during the lame-duck session.
While Alexander has historically been in the minority with his opposition to the credit, the Tennessee Republican said the impending “fiscal cliff” of deep automatic spending cuts and income tax increases set to take effect Jan. 1 has brought other lawmakers to his side. Read more ..
The Race for Solar

Morocco’s ambitious Desertec solar energy project received a setback after Spain failed to show for the official signing of the agreement that aims to transform North Africa’s energy market. The first Desertec project between the EU and Morocco is now under threat as Spain had been an instrumental partner in the project.
Officials from France, Italy, Luxemborg and Malta were in Berlin last week with Moroccan representatives to ink the deal that would begin the process of developing a 100MW PV power plant, 100MW wind power plant and 150MW CSP power plant to export electricity to Europe.
Spain is seen as a key participant in the Desertec project since a major transmission line connecting North Africa to Europe would need to go through Spain before reaching the rest of Europe. Now the signing is on hold and the Moroccan government is frustrated that it could dampen the overall make-up of the solar energy project. “This is just a hiccup and we fully expect to hear from Spain and see what the issue is that is holding them back from moving forward on this grand project that will deliver renewable energy for Africa and Europe,” said a top government official.

The oil industry’s long record of success in defending its tax breaks faces new tests as lawmakers and the White House negotiate to avoid the “fiscal cliff.” House Speaker John Boehner (R-Ohio) won’t rule out targeting oil-industry deductions in a broad deal to avoid the higher income tax rates and deep automatic spending cuts set to take effect in 2013. “The details will have to be negotiated. Not going to speculate on what a final package may look like,” Boehner spokesman Kevin Smith told The Hill. The Speaker is seeking a deal with the White House that would include new tax revenues without raising rates, a stance that has shifted the focus to the deductions and loopholes in the IRS code.
The American Petroleum Institute (API), the industry’s biggest lobbying group, is bracing for fresh attacks against incentives that oil companies say are nourishing the nation’s oil-and-gas production boom. Read more ..

President Obama's top campaign consultant said an energy report released Monday that projects the U.S. as the world’s biggest oil producer by 2020 shows the president's policies are working.
The International Energy Agency's voluminous report on worldwide energy markets noted that the “Energy renaissance in the United States is redrawing the global energy map.”
David Axelrod, Obama’s former senior adviser, cited the report in a tweet that praised the president’s energy stance. “All-of-the-above strategy moves America closer to energy independence,” Axelrod tweeted Monday. Republicans have pilloried Obama on energy policy. They say the president has restricted oil-and-gas development on federal lands while favoring green energy subsidies for technology that Republicans contend is uncompetitive and a waste of taxpayer dollars.

The Environment on Edge
|Ben Geman||November 12th 2012|
The European Union is halting rules that would force airlines, including U.S. carriers, to pay for their carbon emissions, a move that arrives as U.S. lawmakers seek to shield domestic airlines from the requirements.
EU climate chief Connie Hedegaard said the rules are on hold for a year to allow the United Nations' International Civil Aviation Organization time to reach a global agreement on aviation emissions, according to Reuters. “To create a positive atmosphere, we have agreed to stop the clock,” she said of the exemption for airlines outside the EU.
On Capitol Hill, the House is slated to vote Tuesday in agreement with the Senate’s version of a bill that shields U.S. airlines from paying greenhouse gas emissions costs imposed by European officials.
Airlines for America, an industry trade group, said it’s “cautiously optimistic” about the EU action but still wants Congress to press ahead with the legislation. Read more ..

The Interior Department on Friday issued a final plan to close 1.6 million acres of federal land in the West originally slated for oil shale development.
The proposed plan would fence off a majority of the initial blueprint laid out in the final days of the George W. Bush administration. It faces a 30-day protest period and a 60-day process to ensure it is consistent with local and state policies. After that, the department would render a decision for implementation.
The move is sure to rankle Republicans, who say President Obama’s grip on fossil fuel drilling in federal lands is too tight. Interior’s Bureau of Land Management cited environmental concerns for the proposed changes. Among other things, it excised lands with “wilderness characteristics” and areas that conflicted with sage grouse habitats. Read more ..
The Race for Natural Gas
|Arwa Aburawa||November 10th 2012|
With Tunisians protesting Shell’s shale gas plans and Jordanians set to finalise a deal to build the region’s first oil shale plant by the end of the year, it seems that the region is buying into shale. In Tunisia, shale gas is being marketed as low carbon and more environmentally-friendly but the latest research by scientist shows that it is far from that. Examining emissions in the US after the country began burning less coal due to shale gas production, researchers at the Tyndall Centre for Climate Change Research, found that overall emissions had actually gone up. Why? Well, because millions of tonnes of unused coal are being exported to the UK, Europe and Asia.
“Research papers and newspaper column inches have focussed on the relative emissions from coal and gas, “explains Dr John Broderick, lead author on the report from the Tyndall Centre. “However, it is the total quantity of CO2 from the energy system that matters to the climate. Despite lower-carbon rhetoric, shale gas is still a carbon intensive energy source.” US CO2 emissions from domestic energy have declined by 8.6 percent since a peak in 2005, but researchers warn that more than half of the recent emissions reductions in the energy sector may be displaced overseas by the trade in coal.Professor Kevin Anderson of the Tyndall Centre notes: “Earlier Tyndall analysis suggests that the role for gas in a low carbon transition is extremely limited, with shale gas potentially diverting substantial funds away from genuinely low and zero carbon alternatives.” So there you have it. Shale gas isn’t the answer to all our prayer – it’s more like a huge distraction from renewables and consequently needs to be ignored. Read more ..

A fermentation technique once used to make cordite, the explosive propellant that replaced gunpowder in bullets and artillery shells, may find an important new use in the production of advanced biofuels. With the addition of a metal catalyst, researchers at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that the production of acetone, butanol and ethanol from lignocellulosic biomass could be selectively upgraded to the high volume production of gasoline, diesel or jet fuel.
Using the bacterium Clostridium acetobutylicum, the Berkeley Lab researchers fermented the sugars found in biomass into the solvent acetone and the alcohols butanol and ethanol, collectively known as “ABE” products. They then catalyzed these low carbon number products with the transition metal palladium into higher-molecular-mass hydrocarbons that are possible precursors to the three major transportation fuel molecules. The specific type of fuel molecule produced – whether a precursor to gasoline, diesel or jet – was determined by the amount of time the ABE products resided with the palladium catalyst. Read more ..
The Race for Biofuel

It looks like Mother Nature was wasting her time with a multimillion-year process to produce crude oil. Michigan Engineering researchers can "pressure-cook" algae for as little as a minute and transform an unprecedented 65 percent of the green slime into biocrude. "We're trying to mimic the process in nature that forms crude oil with marine organisms," said Phil Savage, an Arthur F. Thurnau professor and a professor of chemical engineering at the University of Michigan.
Savage's ocean-going organism of choice is the green marine micro-alga of the genus Nannochloropsis. To make their one-minute biocrude, Savage and Julia Faeth, a doctoral student in Savage's lab, filled a steel pipe connector with 1.5 milliliters of wet algae, capped it and plunged it into 1,100-degree Fahrenheit sand. The small volume ensured that the algae was heated through, but with only a minute to warm up, the algae's temperature should have just grazed the 550-degree mark before the team pulled the reactor back out.

Assumptions about who will be the future ruler of Saudi Arabia -- the world's largest oil exporter and self-declared leader of the Islamic world -- need to be revised after the sudden resignation of one of the royal family's senior-most members. Today's surprise announcement that Interior Minister Prince Ahmed bin Abdulaziz has been relieved of his duties and replaced by his nephew, Prince Muhammad bin Nayef, introduces fresh elements of competition into the kingdom's ruling structure.
At 72 years old, Prince Ahmed is the youngest of the so-called "Sudairi Seven," the largest group of full brothers among the many sons of Ibn Saud, the modern kingdom's founder. In recent months, he had seemed to be emerging as a possible future king. The current monarch, King Abdullah, will turn 90 next year and is in failing health, while Crown Prince Salman (76) is widely reported to be in a poor mental state. When former crown prince Nayef bin Abdulaziz died in June, Ahmed replaced him at the Interior Ministry and organized last month's Hajj pilgrimage, an event that went off without mishap.
Prior to the latest news, Prince Muhammad bin Nayef had long served as assistant interior minister, charged with supervising the kingdom's counterterrorism efforts -- a role that he performed, according to many foreign officials, very competently. But he was not promoted to the vacant position of deputy interior minister during the summer, leading to speculation that he had been sidelined. Now, to the contrary, he has suddenly become the first of his generation to be awarded a senior ministerial post.
The Race for Solar
|Tafline Laylin||November 7th 2012|
As part of its plan to shake off its unprofitable solar shackles, including Israel’s Solel initiative, German giant Siemens has exited the ambitious Desertec project. But that doesn’t seem to have deterred the strength of the initiative, which is designed to enable Europe to import one fifth of its power by 2050 from renewable energy plants scattered across Algeria, Egypt, Morocco, Tunisia and other North African and Middle Eastern countries, as firms in China and other countries make moves to get involved.
China’s State Grid Corp (SGCC) expressed an interest in becoming involved in the $514 billion Desertec renewable energy project, according to a conglomerate spokesperson. This news comes just after Siemens’ announcement that it is severing its solar arm, which included both the Desertec and Solel initiatives.
Energy generated by solar and wind plants in North Africa will be evacuated to Europe via cables that will run under the Mediterranean Sea, so it’s uncertain how SGCC expects to benefit from a partnership except as a shareholder. But the firm’s interest does show a growing faith that it can succeed. Despite criticism of the project’s ambitious scope and costs, progress continues apace. Read more ..

Whether we admit it or not, when we drive we want to get from point A to point B as fast as possible. At least that’s the case for about 90 percent of us, says Eyal Pe’er, an Israeli psychologist who studies speeding –– why we do it, and what might make us slow down.
Now in the United States for his post-doctoral fellowship at Carnegie Mellon University, the Fulbright Scholar is working on ways to better educate people about the risks and consequences of speeding.
Pace-O-Meter, a device Pe’er invented as an add-on for a car’s digital speedometer, not only provides information about how many miles per hour drivers are traveling, but also shows how many minutes it will take them to complete a given journey at a certain speed. He says it’s different than the GPS feature to calculate estimated time of arrival, and it can help people get a better handle on how little time they actually save by speeding. Read more ..

U.S. petroleum imports are heading below 40 percent in 2013 for the first time in more than two decades, and crude oil production is currently at its highest level since 1997, according to the federal Energy Information Administration (EIA). The agency’s monthly forecast shows continuing trends in growing U.S. production and declining imports.
U.S. crude production is expected to average 6.3 million barrels-per-day in 2012, which is almost 700,000 barrels-per-day above 2011 levels and the highest output since 1997, according to EIA, the Energy Department’s independent statistical forecasting arm. The oil boom in North Dakota and Texas had the biggest hand in boosting output, the agency said. U.S. production in 2013 is forecast to grow to 6.8 million barrels-per-day. Read more ..
The Edge of Climate Change
|Zack Colman||November 6th 2012|
The continued use of fossil fuels could push global temperatures 10.8 degrees Fahrenheit (6 degrees Celsius) higher by the end of the century, according a report released Monday.
While nearly 200 nations at the 2009 United Nations Framework Convention on Climate Change agreed to limit the average global temperature increase to 3.6 degree Fahrenheit (2 degrees Celsius) by 2050, too few nations have taken measurable steps to hitting that mark, accounting firm PricewaterhouseCoopers said in its annual carbon report.
That makes "ambitions to limit warming to 2 [degrees Celsius] appear highly unrealistic,” the report said. “Even doubling our current rate of decarbonisation, would still lead to emissions consistent with 6 degrees of warming by the end of the century. To give ourselves a more than 50 percent chance of avoiding 2 degrees will require a six-fold improvement in our rate of decarbonisation,” Leo Johnson, a partner in PricewaterhouseCoopers’ sustainability and climate change practice, wrote in the report.
To meet that goal, the world would need to reduce its carbon intensity by 5.1 percent per year through 2050. From 2010 until 2011, carbon intensity fell 0.7 percent worldwide, the report said.
Fossil fuels are inhibiting that progress, the report said. While overall worldwide carbon intensity fell, energy-related emissions rose 3 percent. The United States, for its part, has seen its carbon dioxide emissions drop to a 17-year low. The report said U.S. energy-related emissions fell 1.9 percent in 2011, while its overall carbon intensity dropped 3.5 percent. Read more ..

In communities across the U.S., people are hearing more and more about a controversial oil and gas extraction technique called hydraulic fracturing – aka, hydro-fracking. Controversies pivot on some basic questions: Can hydro-fracking contaminate domestic wells? Does it cause earthquakes? How can we know? What can be done about these things if they are true? A wide range of researchers will address these and related critical questions at the GSA Annual Meeting this week.
"When people talk about contamination from hydraulic fracturing, for instance, they can mean a lot of different things," says hydrogeologist Harvey Cohen of S.S. Papadopulos & Associates in Bethesda, Maryland. "When it's what's happening near their homes, they can mean trucks, drilling machinery, noise." These activities can potentially lead to surface water or groundwater contamination if there are, for example, accidental fuel spills. People also worry about fracking fluids leaking into the aquifers they tap for domestic or municipal water. Read more ..

Suspect replacement parts at South Korea's nuclear plants have prompted the government to order the immediate shutdown of two power-generating reactors. Reactors five and six at the Yeonggwang nuclear complex were ordered to go offline on November 5.
Government officials say, before they can re-start the reactors, technicians will need to replace thousands of fuses, cooling fans and other parts. Minister of Knowledge Economy Hong Suk-woo says the components that were installed came with forged quality certificates. The minister says these are non-core components and such parts do not pose a safety threat. He adds there is no connection between the possibly counterfeit parts and a series of malfunctions at South Korea's nuclear reactors this year. Read more ..

Following the accident at the Fukushima Daiichi Nuclear Power Station in 2011, the German government took the nation's eight oldest reactors offline immediately and passed legislation that will close the last nuclear power plant by 2022. This nuclear phase-out had overwhelming political support in Germany. Elsewhere, many saw it as "panic politics," and the online business magazine Forbes.com went as far as to ask, in a headline, whether the decision was "Insane -- or Just Plain Stupid."
But a special issue of the Bulletin of the Atomic Scientists, published by SAGE, "The German Nuclear Exit," shows that the nuclear shutdown and an accompanying move toward renewable energy are already yielding measurable economic and environmental benefits, with one top expert calling the German phase-out a probable game-changer for the nuclear industry worldwide.

A culture of cheating pervades the guard force at America’s premier processing and storage site for nuclear weapons-grade uranium, according to a new report this week by the Energy Department’s inspector general.
Contract officers and supervisors of the force at the Y-12 plant outside Knoxville, Tennessee, shared advance copies of test materials with patrolmen, said inspector general Gregory H. Friedman, rendering their responses unreliable. But he put the blame squarely on the Energy Department for mismanaging the facility’s operations.
The abuses he cited are not new. Eight years ago, Friedman blew the whistle on even worse cheating by the Y-12 guard force, disclosing that for years they obtained advance word of mock assaults meant to test their capabilities, and carefully redeployed their forces to produce impressive but faked results.

America After Sandy
|Zack Colman||November 3rd 2012|
The Energy Department (DOE) will tap fuel from a home heating oil reserve to address a “severe energy supply interruption” caused by superstorm Sandy, DOE said Friday. DOE will loan 2 million gallons of fuel from its Northeast Home Heating Reserve to first-responders in New York and New Jersey to aid recovery efforts. The fuel will be used in emergency equipment, backup generators, buildings, water pumps, trucks and other vehicles, DOE said.
“Today’s announcement is part of the broader federal effort to respond to those impacted by Hurricane Sandy,” Energy Secretary Steven Chu said in a statement. “This loan from the Northeast Home Heating Oil Reserve will help ensure state, local and federal responders in the impacted area have access to the diesel fuel they need to continue response and recovery efforts.” Read more ..

With its strong dependence on gas-turbine engines for propulsion, the U.S. Navy is always looking for ways to improve the fuel consumption of these engines. At the Naval Research Laboratory (NRL), scientists are studying the complex physics of Rotating Detonation Engines (RDEs) which offer the potential for high dollar savings by way of reduced fuel consumption in gas-turbine engines, explains Dr. Kazhikathra Kailasanath, who heads NRL's Laboratories for Computational Physics and Fluid Dynamics.
Many Navy aircraft use gas-turbine engines for propulsion, with the Navy's gas-turbine engines being fundamentally similar to engines used in commercial airplanes. The Navy also depends on gas-turbine engines to provide propulsion and electricity for many of its ships. Even as future ships move toward the model of an "all electric" propulsion system, they will still need gas-turbine engines to produce electricity for the propulsion system and other critical systems. So building a gas-turbine engine that can handle the Navy's requirements for its warfighting ships and provide a fuel-efficient engine is a high priority for researchers. Read more ..
The Race for Batteries

Researchers at Rice University have refined silicon-based lithium-ion technology by literally crushing their previous work to make a high-capacity, long-lived and low-cost anode material with serious commercial potential for rechargeable lithium batteries.
The team led by Rice engineer Sibani Lisa Biswal and research scientist Madhuri Thakur reported in Nature's open access journal Scientific Reports on the creation of a silicon-based anode, the negative electrode of a battery, that easily achieves 600 charge-discharge cycles at 1,000 milliamp hours per gram (mAh/g). This is a significant improvement over the 350 mAh/g capacity of current graphite anodes. That puts it squarely in the realm of next-generation battery technology competing to lower the cost and extend the range of electric vehicles. Read more ..
The Race for Wind
|Ben Gemen||November 2nd 2012|
Critics of tax credits for wind energy projects are intensifying their push to kill the incentive with a study that calls it “rent seeking” by an established industry that doesn’t need the subsidy. The conservative American Energy Alliance (AEA) unveiled the study Thursday as wind power companies — joined by allies including President Obama — are pushing Congress to renew credits that are scheduled to lapse at year’s end. AEA, which receives some of its funding from fossil fuel companies, is circulating the study on Capitol Hill ahead of a lame-duck battle over the fate of the multibillion-dollar incentive. The group is also promoting the study to editorial boards, governors and others.
AEA commissioned a study by Louisiana State University economist David Dismukes that argues the 20-year-old production tax credit (PTC) provides “training wheels” to an industry that doesn’t need them — especially at taxpayers’ expense. Read more ..

Stanford University scientists have built the first solar cell made entirely of carbon, a promising alternative to the expensive materials used in photovoltaic devices today.
"Carbon has the potential to deliver high performance at a low cost," said study senior author Zhenan Bao, a professor of chemical engineering at Stanford. "To the best of our knowledge, this is the first demonstration of a working solar cell that has all of the components made of carbon. This study builds on previous work done in our lab."
Unlike rigid silicon solar panels that adorn many rooftops, Stanford's thin film prototype is made of carbon materials that can be coated from solution. "Perhaps in the future we can look at alternative markets where flexible carbon solar cells are coated on the surface of buildings, on windows or on cars to generate electricity," Bao said.
The coating technique also has the potential to reduce manufacturing costs, said Stanford graduate student Michael Vosgueritchian, co-lead author of the study with postdoctoral researcher Marc Ramuz. Read more ..

In an economically distressed pocket of southwest Detroit known by its ZIP code — 48217 — the weekend of September 7-9 was one of the worst, pollution-wise, residents like Theresa Shaw could remember. “I started smelling it on Thursday,” said Shaw, who immediately suspected the Marathon Petroleum Co. refinery a half-mile from her house. “I kept the windows closed because I couldn’t breathe. On Friday, I thought, ‘What the heck are they doing?’ My eyes were just burning, my throat was hurting, my stomach was hurting. I was having migraine headaches. “The smell, it was like this burning tar, with that benzene and that sulfur. I wanted to scream.”
Shaw retreated to her sister’s house on the north side of town. Responding to citizen complaints, the Michigan Department of Environmental Quality traced the powerful odor to Marathon, which had been cleaning several large vessels, and wrote up the company for a nuisance violation. Marathon says it is “committed to environmental responsibility” and acted quickly to correct the odor problem, a byproduct of plant maintenance. Read more ..
The Race for Hydrogen
|Dr. Michael Hagmann||October 31st 2012|
Hydrogen production by solar water splitting in photoelectrochemical cells (PEC) has long been considered the holy grail of sustainable energy research. Iron oxide is a promising electrode material. An international team of researchers led by Empa, the Swiss Federal Laboratories for Materials Science and Technology, have now gained in-depth insights into the electronic structure of an iron oxide electrode – while it was in operation. This opens up new possibilities for an affordable hydrogen production from solar energy.
Hematite, the mineral form of iron oxide (or trivially, rust), is a promising anode material for photoelectro-chemical cells (PEC) because of its affordability, availability, high stability and good spectral match to the solar spectrum. Although it has the potential of a 15 percent solar-to-hydrogen energy conversion efficiency, its actual efficiency is lower than that of other metal oxides. This is due to hematite’s electronic structure, which only allows for ultrashort electron-hole excited-state lifetimes. Read more ..

The next big thing in fuel could come from repurposed plastic. However, only seven percent of plastic waste in the United States is recycled each year, according to the Environmental Protection Agency. A company in Niagara Falls, New York, is working to increase that percentage, with an eye toward reducing America’s dependence on foreign oil.
It's a machine known as the “plastic-eating monster.” Every hour, thousands of kilograms of shredded milk jugs, water bottles, and grocery bags tumble into its large combustion chamber. The waste plastic comes from landfills and dumps across the United States. John Bordyniuk, who runs his namesake company, JBI, Inc., invented the new process for converting plastic into a range of fuels. Read more ..

Even as some solar projects are just taking flight in Israel, underlining a new wave of optimism about the technology’s ability to succeed in the country, other solar giants are taking their leave of Israel. International energy and infrastructure giant, Siemens, announced last Monday that it was closing down its Siemens-Solel plant in Beit Shemesh, Israel. In the process, 70 of the concentrated solar power (CSP) plant’s employees were laid off.
“Due to the changed framework conditions, lower growth and strong price pressure in the solar markets, the company’s expectations for its solar energy activities have not been met,” said Michael Suess, member of the managing board of Siemens AG and CEO of the energy sector.
“The global market for concentrated solar power has shrunk from 4 gigawatts to slightly more than 1 gigawatt today. In this environment, specialized companies will be able to maximize their strengths,” Suess added. Read more ..
Energy vs Environment
|Michael Bernstein||October 29th 2012|
Putting a speed limit on cargo ships as they sail near ports and coastlines could cut their emission of air pollutants by up to 70 percent, reducing the impact of marine shipping on Earth's climate and human health, scientists have found. Their evaluation of the impact of vessel speed reduction policies, such as those proposed by the California Air Resources board, appears in ACS' journal Environmental Science & Technology. David R. Cocker III and colleagues explain that marine shipping is the most efficient form of transporting goods, with more than 100,000 ships carrying 90 percent of the world's cargo. However, engines on these vessels burn low-grade oil that produce large amounts of air pollution. Because fuel consumption and smokestack emissions increase exponentially with speed, the authors explored how speed limits could reduce pollution. Read more ..

US CO2 emissions from domestic energy have declined by 8.6% since a peak in 2005, the equivalent of 1.4% per year. However, the researchers warn that more than half of the recent emissions reductions in the power sector may be displaced overseas by the trade in coal. Dr John Broderick, lead author on the report from the Tyndall Centre for Climate Change Research, comments: "Research papers and newspaper column inches have focussed on the relative emissions from coal and gas.
"However, it is the total quantity of CO2 from the energy system that matters to the climate. Despite lower-carbon rhetoric, shale gas is still a carbon intensive energy source. We must seriously consider whether a so-called "golden age" would be little more than a gilded cage, locking us into a high-carbon future."
Professor Kevin Anderson of the Tyndall Centre notes: "Since 2008 when the shale gas supply became significant, there has been a large increase in US coal exports. This increases global emissions as the UK, Europe and Asia are burning the coal instead. Earlier Tyndall analysis suggests that the role for gas in a low carbon transition is extremely limited, with shale gas potentially diverting substantial funds away from genuinely low and zero carbon alternatives" Read more ..

Research shows newly developed solar powered cells may soon outperform conventional photovoltaic technology. Scientists from the National Renewable Energy Laboratory (NREL) have demonstrated the first solar cell with external quantum efficiency (EQE) exceeding 100 percent for photons with energies in the solar range. (The EQE is the percentage of photons that get converted into electrons within the device.)
While traditional semiconductors only produce one electron from each photon, nanometer-sized crystalline materials such as quantum dots avoid this restriction and are being developed as promising photovoltaic materials. An increase in the efficiency comes from quantum dots harvesting energy that would otherwise be lost as heat in conventional semiconductors. The amount of heat loss is reduced and the resulting energy is funneled into creating more electrical current. Read more ..
The Race for Biofuel

It may sound like a post-season football game for very tiny players, but the "nanobowl" has nothing to do with sports and everything to do with improving the way biofuels are produced. That's the hope of a team of scientists from the Institute for Atom Efficient Chemical Transformations (IACT), an Energy Frontier Research Center led by Argonne National Laboratory (ANL), and including Northwestern University, the University of Wisconsin and Purdue University.
The team is using a layering technique developed for microchip manufacturing to build nanoscale (billionth of a meter) "bowls" that protect miniature metal catalysts from the harsh conditions of biofuel refining. Furthermore, the size, shape, and composition of the nanobowls can easily be tailored to enhance their functionality and specificity. Read more ..

Photovoltaic cell efficiency may soon get a big boost, thanks to next-generation antireflection coatings crafted from nanomaterials capable of cutting down on the amount of light reflected away from a cell's surface.
Materials boasting a "tunable" refractive index have been developed within the past few years, and they show tremendous potential for photovoltaic applications. Professor E. Fred Schubert, of Rensselaer Polytechnic Institute's Department of Electrical, Computer, and Systems Engineering, is investigating ways to exploit this newly gained controllability and will present his findings at the upcoming AVS 59th International Symposium and Exhibition, held Oct. 28 - Nov. 2, in Tampa, Fla.
The refractive index is the property of a material that changes the speed of light, and is computed as the ratio of the speed of light in a vacuum to the speed of light through the material. Among the most fundamental properties of optical materials, the refractive index determines important optical characteristics such as Fresnel reflection, Bragg reflection, Snell refraction, diffraction, and the phase and group velocity of light.
Air and other gases have a refractive index very close to 1.0, but unfortunately aren't viable for thin-film optoelectronic applications. Among transparent dense materials suitable for use in thin-film optoelectronic applications, magnesium fluoride (MgF2) has the lowest refractive index (n=1.39); no dense materials with a lower refractive index are known to exist.

But whether Baghdad can capitalize on this opportunity is far from clear. The stakes are high—both for the global economy and the country’s future.
Despite decades of turmoil and bloodshed, Iraq is already one of the world’s major oil suppliers. The roughly 3 million barrels a day it pumps make it the world’s third-largest exporter. Consider that Iran, hobbled by Western sanctions, is only producing half as much oil today as Iraq, whose wells are putting out more than twice what they did in 2003, the year of the Iraq War.
Yet by the 2030s, according to the IEA, Iraq may double its current output, leapfrogging energy-powerhouse Russia as the second-largest oil exporter in the world. This is hardly a far-fetched forecast. The country’s proven oil reserves are the fifth largest in the world, its proven gas reserves the thirteenth largest. Its actual rank is likely far higher.

The Automotive Edge
|Christoph Hammerschmidt||October 26th 2012|
After extensive tests within the 'SARTRE' projects, carmaker Volvo has taken another step towards autonomous driving by demonstrating a new traffic jam assistance system. The system, whereby the car automatically follows the vehicle in front in slow-moving queues up to 50 km/h, will be ready for series production in 2014.
The traffic jam assistance function is an evolution of the current Adaptive Cruise Control and Lane Keeping Aid technology, which was introduced in the all-new Volvo V40 earlier in 2012. The driver activates the traffic jam assistance function by pushing a button. When active, the engine, brakes and steering respond automatically. The Adaptive Cruise Control enables safe, comfortable driving by automatically maintaining a set gap to the vehicle in front, at the same time as the steering is also controlled. "The car follows the vehicle in front in the same lane. However, it is always the driver who is in charge. He or she can take back control of the car at any time," says Peter Mertens, Senior Vice President Research and Development of Volvo Car Corporation. Read more ..

Gennady Timchenko has long been the invisible man in Russia's ruling elite -- the Keyser Soze of the "collective Putin." He's a Finnish citizen. He lives in Switzerland. And he denies that he even knows President Vladimir Putin all that well. But Timchenko, who left Russia two decades ago, owns Gunvor, the world's fourth largest oil trading company. At its peak, Gunvor handled approximately a third of Russia's seaborne oil exports, making Timchenko a key player in the country's political-energy complex.
And despite his protestations to the contrary, Timchenko is widely rumored to have a KGB past and a long association with Putin. His name shows up on virtually every list of the top officials believed to be part of Putin's informal "politburo." And now, according to Russian media reports, he's coming home. And this has led to a lot of speculation about why, and why now. Explanations from Russian officials, to say the least, were unconvincing. Read more ..
The Race for Alt Fuel
|Arwa Aburawa||October 24th 2012|
Following plans to transform Mecca into a solar city, an influential member of the Saudi Royal family has announced even more ambitious renewable energy plans for the country. Prince Turki Al Faisal Al Saud, founder of the King Faisal Foundation and one of the state’s top spokesmen, said he wants to the country to switch completely from fossil fuels to renewable energy. The prince admitted that the shift would not be complete in his lifetime (he is 67) but that it will happen.
“Oil is more precious for us underground than as a fuel source,” said Prince Turki Al Faisal Al Saud at conference. “If we can get to the point where we can replace fossil fuels and use oil to produce other products that are useful, that would be very good for the world. I wish that may be in my lifetime, but I don’t think it will be.” He said he wanted the country to invest in alternatives to fossil fuels such as renewables, nuclear and other low-carbon sources of energy. Vast oil reserves could then used to create useful materials such as plastics and polymers, he explained. Read more ..
The Race for Geo-Thermal

MENA Geothermal has completed the largest geothermal heating and cooling system in the Middle East and North Africa. Completed in August, 2012, the new and deeply clean energy system at the American University of Madaba (AUM) in Jordan has a total cooling load of 1680 kW and a heating load of 1350 kW, which is enough energy to power both the College of Science and the College of Business.
“It reduces CO2 emissions by 223,638 kg CO2/yr or 47 percent compared with conventional chiller/LPG boiler cooling and heating systems,” the company’s President and Founder Khaled Al Sabawi said the project was constructed using 100 percent local labor and Palestinian engineering and support staff. Construction of the AUM geothermal system began in July, 2010 and involved drilling 420 boreholes in a vertical configuration 100 meters into the ground.
But unlike drilling for shale oil, geothermal energy is considered to be one of the cleanest, most efficient and safest forms of renewable energy, Al Sabawi explains. “The only dangers of geothermal are the same potential dangers associated with any electrical appliance in general, but this is very minimal.” Read more ..

A spokesman for Afghanistan's Mining Ministry, Jawad Omer, has announced that Canadian company Terraseis has located a large oil field in the northwestern part of the country. The site is in the Faryab Province near the border with Turkmenistan.
Omer said more exploration would be done to get an accurate assessment of the size of the oil field. The news comes after the China National Petroleum Corporation started commercial production at an oil field in the neighboring Sar-e Pol Province earlier this week. The news of the oil discovery in Faryab and the start of production in Sar-e Pol has Afghan officials talking about energy self-sufficiency for the country. Northwest Afghanistan is believed to hold vast deposits of oil and natural gas. The Chinese drilling in northern Afghanistan’s Amu Darya basin is part of a 25 year contract with the Afghan government to produce up to 2.25 million barrels of oil by 2014. Read more ..

Disappointing corporate earnings and continuing worries about Spain's battered economy cut stock prices on key European and U.S. exchanges on October 23.
Crude oil prices also declined. France's CAC-40 and Germany's DAX were down more than two percent in late trading. At one point during mid-day trading in New York, the Dow and the S&P 500 were off 1.7 percent or more.
Analysts say the declines follow weaker than expected earnings from major companies like IBM, FedEx, and McDonald's. Chemical company DuPont said it will cut 1,500 jobs after profits declined sharply. Traders apparently saw the disappointing earning reports as a sign that the economy will slow down, cutting demand for energy. That perception is one reason that oil prices declined in key markets.
