Nature Shows how Moth Eyes Increase the Efficiency of Photovoltaics

January 24th 2011

Animals - Moth

The eyes of moths, which allow them to see well at night, are also covered with a water-repellent, anti-reflective coating that makes their eyes among the least reflective surfaces in nature and helps them hide from predators in the dark. Mimicking the moth eye's microstructure, a team of researchers in Japan has created a new film, suitable for mass-production, for covering solar cells that can cut down on the amount of reflected light and help capture more power from the sun.

Congressional Opponents to Disclosure by Natural Gas Extractors Receive Big Industry Checks

Congress isn’t going to regulate hydraulic fracturing any time soon. But the Department of Interior might. For starters, Interior is mulling whether it should require drilling companies to disclose the chemicals they use to frack wells drilled on public lands, and already the suggestion has earned Interior Secretary Ken Salazar an earful.

On January 5, a bipartisan group of 32 members of Congress, who belong to the Natural Gas Caucus, sent Salazar a letter imploring him to resist a hasty decision because more regulations would “increase energy costs for consumers, suppress job creation in a promising energy sector, and hinder our nation’s ability to become more energy independent.”

A week later, 46 House Democrats followed up by signing a letter to Salazar urging him to at least adopt the disclosure requirement because, as Rep. Maurice Hinchey, D-N.Y., said, “communities across America have seen their water contaminated by the chemicals used in the hydraulic fracturing process.”

“The public has a right to know what toxins might be going into the ground near their communities, and what might be leaking into their drinking water,” said the letter, which was sent by the three initial sponsors of now-stalled legislation to regulate fracturing, Hinchey, Rep. Jared Polis, D-Colo., and Rep. Diana DeGette, D-Colo. Read more ..

Following Discovery of Oil, Ghana has a Lot to Learn From Nigeria

January 18th 2011

Africa Topics - Ghana oil

The news filtered around the international media recently that Ghana will start pumping its oil, estimated to be a minimum of 1 billion barrels in reserve. However, this news has been met with both joy and fear. Joy because this means Ghana now joins the league of oil producing countries, with the attendant streams of petroldollar in revenue.

There is the fear of the so-called oil resource ‘curse’ or the paradox of plenty - often used to describe a situation in which countries blessed with abundance of natural resources such as oil tend to have worse economic and development outcomes. This economic phenomenon is sometimes called the Dutch disease.

Macroeconomics traditionally offers some insights into how the ‘blessing’ of abundant natural resources might turned into a ‘curse’ overtime. This may occur when the revenue from oil exports initially leads to increase in real exchange rate and wages. This increase in turn will eventually damage the other productive or tradable sectors of the economy, such as the agriculture and manufacturing, as they become less competitive in world markets.

On the government front, the revenue from oil exports will more likely result in higher government spending (e.g. on education, health), but this is more likely to be financed through deficits in anticipation of higher oil revenue that are vulnerable to vagaries in world oil prices. Overtime, as the real sectors of the economy are exposed to international competition, the revenue from oil also becomes volatile due to exposure to global commodity market shocks, and this leaves the economy largely dependent on oil revenue.

Power Plant: Algae as an Alternative Energy Source

January 10th 2011

Energy Topics - algae

Prof. Avihai Danon of the Weizmann Institute of Science’s Department of Plant Sciences has been working with algae—simple, photosynthetic life forms that can be found all over the world—for more than 20 years. Algae are diverse, having many thousands of species, and adaptive, thriving in a variety of conditions; these attributes can teach scientists a lot and make algae, as Prof. Danon says, “a great model system to study.” For example, in his research focusing on how they adapt to sunlight, Prof. Danon found that there is a very sophisticated level of regulation inside algae. “On the one hand, the plant utilizes sunlight for energy production through photosynthesis,” a process that, while beneficial, must be very carefully calibrated because “on the other hand, it can kill the plant in seconds,” he says. He likes to compare a plant’s ability to perform photosynthesis to having an atomic reactor in your stomach: the reactor can provide you with free energy, but if it’s not tightly controlled, then it can melt down.

Biofuel Grasslands Better for Birds than Ethanol Staple Corn

January 10th 2011

Energy / Environment - Biofuel field

Developing biofuel from native perennials instead of corn in the Midwest’s rolling grasslands would better protect threatened bird populations, Michigan State University research suggests.

Federal mandates and market forces both are expected to promote rising biofuel production, MSU biologist Bruce Robertson says, but the environmental consequences of turning more acreage over to row crops for fuel are a serious concern.

Ethanol in America is chiefly made from corn, but research is focusing on how to cost-effectively process cellulosic sources such as wood, corn stalks and grasses. Perennial grasses promise low cost and energy inputs—planting, fertilizing, watering—and the new study quantifies substantial environmental benefits.

“Native perennial grasses might provide an opportunity to produce biomass in ways that are compatible with the conservation of biodiversity and important ecosystem services such as pest control,” Robertson said. “This work demonstrates that next-generation biofuel crops have potential to provide a new source of habitat for a threatened group of birds.” With its rich variety of ecosystems, including historic prairie, southern Michigan provided a convenient place to compare bird populations in 20 sites of varying size for each of the three fuel feedstocks. Grassland birds are of special concern, Robertson said, having suffered more dramatic population losses than any other group of North American birds. Read more ..

A newly engineered yeast strain can simultaneously consume two types of sugar from plants to produce ethanol, researchers report.

The sugars are glucose, a six-carbon sugar that is relatively easy to ferment; and xylose, a five-carbon sugar that has been much more difficult to utilize in ethanol production. The new strain, made by combining, optimizing and adding to earlier advances, reduces or eliminates several major inefficiencies associated with current biofuel production methods. The findings, from a collaborative led by researchers at the University of Illinois, the Lawrence Berkeley National Laboratory, the University of California and the energy company BP, are described in the Proceedings of the National Academy of Sciences.

From Greenhouse Gases to Green Agenda: Five Energy Issues to Watch

December 27th 2010

Politics - Capitol Building at night

It’s been a dynamic past 12 months on the energy front. The massive Gulf oil spill dominated much of the news cycle. And while Democratic efforts to pass comprehensive climate change legislation in the Senate failed, the Obama administration is moving ahead with plans to use its existing powers to regulate greenhouse gas emissions.

With the end of the year drawing close—the 111th Congress is over and President Obama is in Hawaii with his family for the holidays—it seems only fitting to turn our attention to next year. Without further ado, here are five things to watch out for in 2011.

Attempts to block the Environmental Protection Agency’s climate regulations:

On Thursday, just hours before most people in Washington left town for the holidays, the EPA made two major announcements in its efforts to reduce the country’s greenhouse gas emissions. The agency laid out a timetable for phasing in emissions standards for power plants and refineries, and announced it would issue greenhouse gas permits in Texas, where the governor had refused to align with federal rules. On top of that, beginning in January the EPA will, on a case-by-case basis, begin phasing in rules that require large new industrial plants and sites that perform major upgrades to curb emissions.

Stand before the pond known here in southwestern Pennsylvania as Little Blue Run, and you’ll see nothing that resembles its bucolic-sounding name.

The one-time stream is now an industrial pond, filled with arsenic-laced waste from a coal-fired power plant. The pond spans nearly 1,000 acres of rolling, rural landscape in Pennsylvania and West Virginia, along the Ohio River. Millions of tons of coal ash have landed in the 35-year-old dump, looming over some 50,000 people in southeastern Ohio, held back by a 400-foot-tall dam, that federal regulators have deemed a “high hazard” to human life if it ever let loose.

Fracking Natural Gas Mobilizes Uranium and Concerns about Radioactivity

Environment Topics - Dirty Drinking

Scientific and political disputes over drilling in the Marcellus shale formation and elsewhere in the United States for natural gas have focused primarily on the environmental effects of pumping millions of gallons of water and chemicals deep underground to blast through rocks to release the natural gas.

But researchers at the University of Buffalo in New York State have now found that that process—called hydraulic fracturing or “fracking”—also causes uranium that is naturally trapped inside Marcellus shale to be released, raising additional environmental concerns.

Marcellus shale is a massive rock formation that stretches from New York through Pennsylvania, Ohio and West Virginia, and which is often described as the nation's largest source of natural gas. “Marcellus shale naturally traps metals such as uranium and at levels higher than usually found naturally, but lower than manmade contamination levels,” says Tracy Bank, PhD, assistant professor of geology in UB's College of Arts and Sciences and lead researcher.

However, more than five years after the start of operations, critical gaps in meeting the basic needs of local citizens remain.” -Oxfam

The natural gas industry in Peru has boomed since mid-2004, when natural gas from the Camisea Project, located in the Urubamba Basin in the southeastern Peruvian Amazon, began to flow. At approximately $1.7 billion, Peru’s Camisea Project represents the largest investment in the country’s history. Since the project’s 2004 launch, according to an Oxfam report published in July of 2010, Camisea has been satisfying part of the external market demand for natural gas, albeit at alarmingly low prices dictated by the existing contract.

Gulf of Mexico Oil Spill Response Exacerbates OPEC/Oil Dependence Dilemma

Contributors / Staff - Gal Luft

The three-month oil spill in the Gulf of Mexico has been a stark reminder of one of the intangible costs of the transportation sector's near total dependence on oil. But if there was some hope that from this disaster would emerge policies that aim at strengthening America's energy security now it is clear that nothing close to that is going to happen. To the contrary, official response to the spill has only weakened our energy security. An impulsive moratorium banning exploratory drilling in the Gulf of Mexico, home to about 30 percent of U.S. domestic output, was announced, and two drilling rigs have already set sail, heading to foreign waters where busy drilling schedule is already awaiting them. Drilling rigs are in great demand and once they leave the Gulf of Mexico they are not likely to be back for years.

In response to the spill, Senate Majority Leader Harry Reid introduced a bill comprised of a mishmash of policies that mostly have nothing to do with oil.  A few days after its introduction, Senator Reid pulled the bill in the face of strong opposition and Congress broke for recess.

Haphazard Firefighting Might Have Sunk BP Oil Rig

August 2nd 2010

Energy / Environment - BP Rig fire

The Coast Guard has gathered evidence that it failed to follow its own firefighting policy during the Deepwater Horizon disaster and is investigating whether the chaotic spraying of tons of salt water by private boats contributed to sinking the ill-fated oil rig, according to interviews and documents.

Coast Guard officials reported that the service does not have the expertise to fight an oil rig fire and that its response to the April 20 explosion may have broken the service’s own rules by failing to ensure a firefighting expert supervised the half-dozen private boats that answered the Deepwater Horizon’s distress call to fight the blaze.

An official maritime investigation led by Coast Guard Capt. Hung M. Nguyen in New Orleans is examining whether the salt water that was sprayed across the burning platform overran the ballast system that kept the rig upright, changing its weight distribution, and causing it to list. “The joint investigation is absolutely looking into that, and whether it contributed to the sinking,” Capt. Ronald A. LaBrec, the Coast Guard’s chief spokesman, said.

The joint investigation by the Coast Guard and the Interior Department is one of 10 formal inquiries since the offshore oil well blew out, killing 11 workers and unleashing millions of gallons of oil into the Gulf of Mexico in the worst spill in U.S. history. The disaster entered its 100th day on Wednesday.

While investigators have zeroed in on a series of missteps and ignored safety warnings aboard the rig that preceded the fiery explosion on April 20, the question of what caused the platform to collapse into the Gulf two days later remains unanswered and could prove vital to ongoing legal proceedings and congressional investigations.

However, the story became even stickier for BP as the week ended. While its prices were at their disaster mode low, wealthy Libyan oil moguls were vying for a controlling stake in BP. Shokri Ghanem, chairman of Libya’s Nation Oil Co., with which BP is now doing business with, told Dow Jones Newswires that he will recommend investing in BP to the country’s sovereign wealth fund. Ghanem said in an interview, “BP is interesting now with the price lower by half and I still have trust in BP, I will recommend it to the [Libyan Investment Authority] … It’s a good opportunity for bargain hunters.” BP shares jumped 5 percent on the news out of Libya.

In addition, news on the street is that BP is now seeking increased Middle East investment as it guards against takeovers. European newspapers have reported that BP and the Kuwaiti Investment Authority are discussing increasing the Kuwaits’ existing 1.77 percent share in the company. BP CEO Tony Hayward recently flew to Abu Dhabi to meet Crown Prince Sheikh Mohammed bin Zayed Al Nahyan. Sheikh Mohammed is also the chairman of Mubadala Development, a strategic investment company owned by the Abu Dhabi government. Read more ..

After the BP Spill

Spill Puts K Street To Work

July 19th 2010

Energy / Environment - offshore oil rig

A half-dozen offshore drilling and oil services companies have formed a coalition to push back against the Obama administration’s drilling moratorium.

The Shallow Water Energy Security Coalition has hired lawyers, lobbyists and PR specialists at several K Street shops. Though shallow-water drilling has not been suspended by the White House—only deepwater operations have—the group believes the Interior Department is damaging its business by stalling drilling permits of all kinds.

The coalition is one of several new faces showing up on lobbyists’ row since the explosion that destroyed the Deepwater Horizon oilrig on April 20. There have been at least a dozen new lobbying registrations for companies reacting to new legislation and regulations stemming from the disaster, according to a review of disclosure records.

It’s not just oil companies, though, turning to K Street to defend themselves against the oil spill’s legislative aftermath. Firms that service oil wells and those that can help with the massive cleanup operations have all hired lobbyists either to keep an eye on new, tough safety regulations or to help win cleanup contracts.

GM Disappoints with Lower ‘Volt’age as Restricted Initial Production Announced

July 12th 2010

Energy Topics - Volt

Well, it is finally here, kind of. The answer to oil consumption , the cure for crude, the break from a dependency that has arguably guided the United State’s foreign policy for decades; Chevrolet announced that its electric vehicle for the everyman, the Volt, will be put into proto-production late this year, and many become for sale in 2011. The immediate outlook, however, is not as clear as the emissions the Volt will produce. Chevrolet will only have ten thousand produced for sale in 2011 in just a few states and coast-to-coast demand has for years been vastly greater. In other words, the Volt will be a vehicle of token production until at least 2012, betraying years of promises to unleash abundant production for a market that already enjoys more than 53,000 advance waiting list names. The vehicle is years late. Read more ..

Despite the latest tensions, two companies - one Palestinian and one Israeli - are integrating wind turbines together in the West Bank and beyond.

A path toward peace may be blowing in the wind, if a new wind energy project between a Palestinian and an Israeli company succeeds. The two companies, Israel Wind Power based in Ramat Gan, near Tel Aviv and Brothers Engineering Group from Bethlehem in the West Bank, have just announced their intention to cooperate in the building and selling of wind turbines in the West Bank region and beyond.

Most significant, they are undeterred by the latest tensions between Israel, the Palestinian Authority (PA) and world powers in the wake of the recent Turkish-led flotilla incident that occurred near Gaza. Read more ..

Members of Congress Profit from BP and Transocean Holdings

June 28th 2010

Energy / Environment - Gulf Spill Protesters

Sen. John Kerry of Massachusetts and at least three other federal lawmakers have sold their holdings in companies tied to the Gulf of Mexico oil spill, it has been learned ahead the June 16 disclosure of 2009 personal financial records by all members of Congress.

According to an analysis, 20 members of Congress disclosed owning at least $1,001 worth of shares in BP or Transocean Ltd in their 2008 financial forms filed one year ago.

Kerry has sold his Transocean stock since the 2008 filing but still owns between $1,001 and $15,000 worth of stock in BP, his spokeswoman confirmed. The annual disclosure forms require members of the Senate and House to specify only a general range of asset values, not specific dollar amounts.

Despite his financial interest in the company, the Massachusetts Democrat has taken a hard line on BP in public statements. “I think we can finally get that oil leak plugged if we stuff it with the BP executives’ bonus money,” Kerry, the lead sponsor of a climate bill, said in a speech the previous week.

Senate Energy and Natural Resources Committee Chairman Jeff Bingaman (D-N.M.) plans to unveil legislation next week that would overhaul federal oversight of offshore oil-and-gas drilling and impose new safety standards.

Bingaman is readying the bill ahead of plans by Senate Majority Leader Harry Reid (D-Nev.) to bring wide-ranging energy legislation to the floor as soon as July.

Bingaman spokesman Bill Wicker declined on June 18 to provide details about Bingaman’s bill, but suggested it will be expansive. “It will address all the things which are in the scope of our committee's jurisdiction,” Wicker said.

He said it would be released some time ahead of a June 25 hearing that will explore several pieces of legislation in response to the Gulf of Mexico oil spill. Read more ..
