The Race for LEDs

Market for Hi-brightness LEDs Continues to Show Double-digit Growth

March 11th 2013

LED bulb

Market researcher Digitimes predicts that the inexorable victory run of high-brightness LED will continue - at least for the time being. According to Dgitimes, the global output value of high-brightness LEDs in 2013 will grow by 15.8% during the current year to reach a value of US$11.29 billion. But not all market segments are on the winning side. LED lighting applications are estimated to account for 30% of all LED applications in 2013. Among all LED applications, the percentage of medium and large-size LED backlight applications is forecast to drop to 27.6% in 2013 due to falling shipments of notebooks and monitors. In addition, direct-lit LED TVs require fewer LEDs per unit. The global LED lighting market is likely to achieve an output value of US$25.4 billion in 2013. The penetration rate is expected to grow because there is still room for price drops for LED products. Digitimes estimates the price reductions at around 20-25% in 2013. In addition, the price-performance ratio of LED components in 2013 is forecast to reach 1,000lm/US$1. Furthermore, commercial tubes and ceiling lights that use a higher number of LEDs are the focus for commercial users in 2013, which will help to increase the penetration rate of LED lighting among all lighting products.

Quantum Dot Voltaics Promises Significantly Efficient Solar Cells

March 10th 2013

Sunrise or Sunset

A new technique developed by University of Toronto Engineering Professor Ted Sargent and his research group could lead to significantly more efficient solar cells, according to a recent paper published in the journal Nano Letters.

The paper, “Jointly-tuned plasmonic-excitonic photovoltaics using nanoshells,” describes a new technique to improve efficiency in colloidal quantum dot photovoltaics, a technology which already promises inexpensive, more efficient solar cell technology. Quantum dot photovoltaics offers the potential for low-cost, large-area solar power – however these devices are not yet highly efficient in the infrared portion of the sun’s spectrum, which is responsible for half of the sun’s power that reaches the Earth.

The solution? Spectrally tuned, solution-processed plasmonic nanoparticles. These particles, the researchers say, provide unprecedented control over light’s propagation and absorption. The new technique developed by Sargent’s group shows a possible 35 per cent increase in the technology’s efficiency in the near-infrared spectral region, says co-author Dr. Susanna Thon. Overall, this could translate to an 11 per cent solar power conversion efficiency increase, she says, making quantum dot photovoltaics even more attractive as an alternative to current solar cell technologies.

Brazil Ramps up Sugarcane Production: Regional Climate Effects?

March 8th 2013

Sugar Cane

Conversion of large swaths of Brazilian land for sugar plantations will help the country meet its needs for producing cane-derived ethanol but it also could lead to important regional climate effects, according to a team of researchers from Arizona State University, Stanford University and the Carnegie Institution for Science.

The team found that anticipated conversion to sugarcane plantations could lead to a 1°C decrease in temperature during the growing season, to be followed by a 1°C increase after harvest.

"When averaged over the entire year, there appears to be little effect on temperature," said Matei Georgescu. "However, the temperature fluctuation between the peak of the growing season, when cooling occurs relative to the prior landscape, and crop harvest, when warming occurs compared to the previous landscape, of about 2°C (3.6°F) is considerable."

Senator Menendez Plans Keystone Pipeline Hearing

March 7th 2013

Keystone Pipeline

Senate Foreign Relations Committee Chairman Robert Menendez (D-N.J.) said Thursday that he intends to hold a hearing on the State Department’s review of the proposed Keystone XL oil sands pipeline

“We want to review their process, especially as they go into the next phase,” he said of the State Department’s review of TransCanada Corp.’s proposed pipeline.
The hearing would ensure an even greater spotlight on the looming federal decision over Keystone XL, which would bring Canadian oil sands to Gulf Coast refineries.

A wide-ranging State Department draft environmental report last week dealt a major blow to climate change activists opposed to Keystone. A key conclusion is that Keystone is “unlikely to have a substantial impact on the rate of development in the oil sands,” a finding that counters green group claims that Keystone would be a major catalyst for carbon-intensive oil sands development.

BP CEO: 'Peak Oil' Talk Quieted by Abundance

March 6th 2013

oil pump

BP CEO Robert Dudley said booming oil-and-gas production from sources including onshore shale formations and deepwater regions has defeated arguments that global oil production will soon peak and go into an irreversible decline.

Dudley, in a speech, noted projections of overall global demand energy growing by over a third by 2030, including the need for around 16 million more barrels per day at that time. But he said that the ability produce from oil-and-gas reservoirs that were once out-of-reach will enable supply to keep up.

“Many in the industry used to worry about whether demand on this scale could be met – we weren’t among them by the way – but there hasn’t been much talk of ‘peak oil’ lately,” he said at the IHS CERAWeek energy conference here. “Thanks to new frontiers such as shale and deepwater, our industry is now producing an enormous amount of previously unreachable oil and gas,” Dudley added.

Canadian Official Raps Greens On Oil Pipeline

March 5th 2013

Energy

A top Canadian official on Tuesday delivered a broadside against environmentalists in the United States who oppose the Keystone XL oil sands pipeline. Canadian Natural Resources Minister Joe Oliver touted a U.S. State Department draft environmental review released Friday that dismissed claims from green groups that Keystone would accelerate oil sands development and exacerbate climate change.

“Why then all the fuss? Why the demonstrations and movie stars chaining themselves to the White House gate?” Oliver said in prepared remarks for a Tuesday speech in Chicago, where he met with Mayor Rahm Emanuel.

“The answer is that some environmental and other groups see this as a symbolic issue in their larger battle against the development of hydrocarbons and specifically the oil sands. In a democratic society, they are entitled to their views, but not to take liberties with the truth. The stakes are high for Canada and, I suggest, the U.S. as well,” he said. Environmental activists have tried to make Obama’s decision on the pipeline the litmus test for where he stands on climate issues.

They have denounced the findings of the State Department's draft report, and have sought to remind Obama that he alone will choose whether the Canada-to-Texas pipeline goes forward since it crosses national borders. Green groups contend the proposed pipeline would drive an expansion of oil sands development. They have raised concerns about the climate change impact of burning more oil sands, which are more carbon intensive than traditional crude.

Still, the State Department said the oil sands would come out of the ground regardless of Keystone, either by rail transport or through other pipeline projects. Oliver, who several times invoked the State Department review, defended Canada’s environmental record while downplaying the effects of oil sands on the climate. He reiterated a claim made recently by several Keystone proponents that oil sands account for 0.1 percent of global greenhouse gas emissions. Read more ..

Energy Storage Super Capacitors Bottle Energy in New Breakthrough

March 4th 2013

Plug-in Vehicle

UCLA and Egyptian scientist accidentally find a new way to bottle stored energy. This missing link for solar energy, hydro and electric cars could be a fast, tiny, biodegradable battery.

Penicillin, Teflon, microwave ovens and superglue were all discovered by accident. And now graphene super-capacitors might be the most important accidental discovery of our time – one that can change the way energy is stored. A team of UCLA researchers led by chemist Richard Kaner used a commercial DVD burner to produce sheets of a carbon-based material known as graphene.

The “accident” occured when Cairo University graduate Maher El-Kady wired a small piece of graphene to an LED and found that it behaved as a super-capacitor, able to store a considerable amount of electricity. Their laser-scribed graphene is ideal as a super capacitor partially because of its enormous surface area, 1520 square meters per gram. Here’s how it works: Read more ..

Keystone XL Pipeline Clears a Hurdle

March 2nd 2013

Keystone Pipeline

A draft State Department report concludes that building the Keystone XL pipeline would not speed up development of Canada’s oil sands, dealing a blow to environmentalists who claim Keystone would worsen climate change.

The report from the State Department says the Canada-to-Texas pipeline would have little impact on the environment.
“Approval or denial of the proposed project is unlikely to have a substantial impact on the rate of development in the oil sands, or on the amount of heavy crude oil refined in the Gulf Coast area," the report says.

That line infuriated green groups, which have made the case that approving the full Keystone pipeline would lock in expanded development of carbon-intensive oil sands projects and the expanded use of the fuels, worsening climate change over time. Read more ..

Senate to Hold Hearing on Surge in Gas Prices

March 1st 2013

Gas

Senate Energy and Natural Resources Committee Chairman Ron Wyden (D-Ore.) will soon convene a hearing on soaring gasoline prices that he contends have “no reasonable explanation.” Average nationwide gasoline prices have risen by nearly a half-dollar per gallon since the beginning of the year.

“I think you ask the question, ‘what is going on to make the prices go up so dramatically now?’ The custom has always been — one we didn’t enjoy in America but it has been sort of a tradition — [that] prices go up in the spring. We are still in the winter,” Wyden said Friday. He spoke during a taping of the C-SPAN program “Newsmakers” that will be broadcast Sunday.

“There is no reasonable explanation for this right now. The Iranians are not rattling around this week in the Straits of Hormuz, we have not see any kind of unusual developments, that is why I want to look at a whole host of issues, and one that hasn’t been on the table at all has been the question of refineries,” Wyden said.

Gulf Exploration Deal with Mexico Headed to Congress

February 28th 2013

Gulf oil spill

The Obama administration will shortly be asking Congress to approve last year's deal with Mexico for oil exploration in the Gulf, the State Department said.

The so-called Transboundary Hydrocarbons Agreement, signed by then-Secretary of State Hillary Clinton and President Felipe Calderón on the margins of last year's G-20 summit in Los Cabos, establishes a legal framework for joint U.S.-Mexican exploration. The agreement also lifts the moratorium on oil exploration and production in the Western Gap portion of the Gulf of Mexico.

“Let me assure you that this will be coming in front of Congress,” Roberta Jacobson, the assistant secretary of State for the Western Hemisphere, said Thursday at a House hearing on U.S. interests in the region. “I hope we can count on everyone's support. We hope to do that as expeditiously as possible.” Read more ..

Shell Pauses Arctic Drilling Effort

February 27th 2013

Alaska oil drilling

Royal Dutch Shell said Wednesday that it will not seek to drill in Arctic waters off Alaska’s coast in 2013, an announcement that follows several mishaps last year for the controversial development effort.

“We’ve made progress in Alaska, but this is a long-term program that we are pursuing in a safe and measured way,” said Marvin Odum, who heads the oil giant’s U.S. operations, in a statement. “Our decision to pause in 2013 will give us time to ensure the readiness of all our equipment and people following the drilling season in 2012,” added Odum.

Shell has spent years — and billions of dollars — seeking to drill in the Beaufort and Chukchi seas off Alaska’s northern coast, which are thought to contain massive oil deposits. Shell, in announcing the decision to “pause” the drilling, said it plans to return to the Arctic eventually, noting “Alaska remains an area with high potential for Shell over the long term, and the company is committed to drill there again in the future.” Read more ..

Graphene Viable Alternative Material For Light-Based Energy Harvesting Technologies

February 27th 2013

graphene

Researchers at the Institute of Photonic Science (ICFO) have demonstrated that graphene is able to convert a single photon that it absorbs into multiple electrons that can drive electric current to make graphene an alternative material for light harvesting technologies.


"In most materials, one absorbed photon generates one electron, but in the case of graphene, we have seen that one absorbed photon is able to produce many excited electrons, and therefore a greater electrical current" explained Frank Koppens, group leader at ICFO. This feature makes graphene an ideal building block for any device that relies on converting light into electricity. In particular, it enables efficient solar cells that can harvest light energy from the full solar spectrum with low loss. Read more ..

Spray Painted Solar Cells Could Cut Costs Significantly

February 26th 2013

the sun

Experts from the University of Sheffield's Department of Physics and Astronomy and the University of Cambridge have created a method of spray-coating a photovoltaic active layer by an air based process - similar to spraying regular paint from a can.

This could yield a very cheap way of mass-producing solar cells. If successful, the technology could be provided to people in developing countries and perhaps one day be used on glass in buildings or car roofs, explain the researchers.

Professor David Lidzey from the University of Sheffield said "Spray coating is currently used to apply paint to cars and in graphic printing. We have shown that it can also be used to make solar cells using specially designed plastic semiconductors. We found that the performance of our spray coated solar cells is the same as cells made with more traditional research methods, but which are impossible to scale in manufacturing. We now do most of our research using spray coating. The goal is to reduce the amount of energy and money required to make a solar cell. This means that we need solar cell materials that have low embodied energy, but we also need manufacturing processes that are efficient, reliable and consume less energy." Read more ..

Wyden to Ask for GAO Examination of Washington State Nuclear Leaks

February 23rd 2013

Nuclear Reactors

Sen. Ron Wyden (D-Ore.), the chairman of the Senate Energy committee, has asked the Government Accountability Office (GAO) to examine recent nuclear waste leaks in Washington state.

Wyden has long had an interest in the contaminated Hanford nuclear reservation in southeast Washington, where six tanks are now said to be leaking. Gov. Jay Inslee of Washington, a Democrat, and Energy Department officials have stressed that neither the public nor the environment is currently at risk from the underground leaks.

But Tom Towslee, a spokesman for Wyden, said that the Oregon Democrat will ask the GAO to investigate how the Hanford tanks, which hold tens of millions of gallons of radioactive waste, are monitored and maintained. The request was earlier reported by the Associated Press. Read more ..

As EPA Delays New Coal Ash Rules, Residents Turn to the Courts for Relief

February 22nd 2013

Coal ash

Sabrina Mislevy is tired of the odors, the way they “hit” her as she drives by the blue-tinted lake, the way they burn her nose. Like many of her neighbors, Mislevy has grown weary of living near the nation’s largest coal ash pond, Little Blue Run, which straddles the Pennsylvania, West Virginia and Ohio state lines.

In Little Blue Run and beyond, coal ash, waste from the production of electricity, has fouled water supplies and endangered public health. “We want action,” said Mislevy, of Georgetown, Pa., explaining why she has joined some 200 other area residents in launching legal challenges against FirstEnergy Corp., the owner of Little Blue Run. Her community is just one across the country pursuing legal challenges against coal-ash ponds, landfills and pits — a grassroots onslaught stoked, in part, by slow regulatory action by the Environmental Protection Agency.

Last May at Little Blue Run, residents laid the groundwork for a potential citizens’ suit against FirstEnergy, sending a notice of intent to sue. Calling themselves the Little Blue Regional Action Group, they accused the company of operating its 1,000-acre ash pond “in a manner that may present an imminent and substantial endangerment to human health and the environment.” In December, residents sent another notice to FirstEnergy alleging “additional significant and ongoing violations,” including dirtying a creek that flows into the Ohio River with arsenic and selenium — toxic constituents found in coal ash. A FirstEnergy spokesman, Mark Durbin, calls the residents’ claims “wholly without merit.” Read more ..

President Obama’s rumored choice for Energy secretary is giving heartburn to some in the environmental movement. Ernest Moniz, a physicist at the Massachusetts Institute of Technology and familiar presence in Washington, has emerged as the front-runner to replace Steven Chu as Obama’s energy chief.

That’s not sitting well with green advocates, who say Moniz’s support for natural gas is at odds with the risks of “fracking,” the controversial drilling process, and the need for tough steps to address climate change.

“Moniz is a status quo pick at a time when we can’t afford the status quo,” said Tyson Slocum, who heads the energy program at Public Citizen.

Sources tracking the selection process say Obama is leaning strongly toward picking Moniz, who served as undersecretary of Energy in the Clinton administration and currently directs the MIT Energy Initiative. Read more ..

Imagine if your home had walls filled with water, toilets that composted their own waste and a roof capable of disinfecting water through the sun's UV rays.

This vision may become reality for one Ann Arbor MI home, as a group of engineering students from the University of Michigan work to retrofit a 100-year-old Victorian to capture and treat its own water. The home belongs to the Grocoff family, and is an unassuming structure in the heart of the town's "Old West Side." It has already achieved recognition as one of the country's first Net Zero Energy homes—meaning the house produces more energy through the use of solar panels and geothermal than it consumes.

Now, owner Matt Grocoff and the team of Michigan Engineering students hope to accomplish that same feat with water—something that, to their knowledge, has never been done on this type of structure. Their goal is to capture and treat enough rainwater on site to supply the house with clean drinking water then find creative solutions for recycling or reusing waste water for cleaning or irrigation.

Top Oil Lobbyist: New Climate Bill Will Never Reach Senate Floor

February 21st 2013

Hurricane Sandy

The head of a powerful oil industry trade group predicts the Senate will shy away from debate on new Democratic legislation that imposes fees on carbon emissions from coal and petroleum.

American Petroleum Institute CEO Jack Gerard said he did not expect the Senate to vote on the bill sponsored by Sens. Barbara Boxer (D-Calif.) and Bernie Sanders (I-Vt.).

“I think no, it will not get to the floor, and I think the reason it won't get to the floor is the dynamics surrounding carbon has changed,” Gerard told E&E TV. Boxer said she wants the bill to get a vote, but a spokesman for Senate Majority Leader Harry Reid (D-Nev.) was noncommittal last week. Gerard noted that the expansion of natural gas production, which is allowing gas to increasingly displace more carbon-heavy coal, has helped drive the recent reduction of U.S. carbon emissions without legislation.

Renewables Constitute All New US Electricity Capacity Added in January

February 20th 2013

Wind Farm

Renewable energy accounted for all new electric capacity added in the United States last month, according to the Federal Energy Regulatory Commission. In all, 1,231 megawatts of new generating capacity were installed in January. Of that total, wind provided 958 megawatts, solar chipped in 267 megawatts and biomass contributed 6 megawatts.

That's a marked difference from January 2012, when coal led the way with 808 megawatts of the 1,693 megawatts added. Natural gas followed with 445 megawatts, and wind tossed in 276 megawatts to take the pole for renewables. On Wednesday, President Obama sought to expand promotion of renewable energy by reviving the Commerce Department’s Renewable Energy and Energy Efficiency Advisory Committee.

Petition Seeks New EpA Pathway to Require Greenhouse Gas Curbs

February 19th 2013

LA Smog

An environmental group affiliated with New York University’s law school is petitioning the Environmental Protection Agency (EPA) to wield a seldom-used section of the Clean Air Act to require greenhouse gas emissions curbs.

The petition urges EPA to act under Section 115 of the air law, which enables EPA to demand action to curb pollution that’s endangering public health or welfare in foreign countries.

“Section 115 provides a mandatory, efficient, and comprehensive approach to regulating greenhouse gas emissions. It is therefore the preferred mechanism under the Clean Air Act for responding to the dangers of climate change,” states the Institute for Policy Integrity’s petition, to be filed Tuesday.

The attorneys, in the petition and an accompanying statement, argue that Section 115 should be employed to have EPA require states to control emissions, while providing the ability to use “flexible regulatory tools like market incentives” such as cap-and-trade. Read more ..

What Green Algae Are Up To In the Dark

How green algae produce hydrogen in the dark is reported by biologists at the Ruhr-Universität Bochum in the "Journal of Biological Chemistry". Hereby, they have uncovered a mechanism for the production of the gas which has hardly been examined before; usually, researchers are interested in light-driven hydrogen synthesis. "Hydrogen could help us out of the energy crisis", says Prof. Dr. Thomas Happe, head of the working group Photobiotechnology. "If you want to make green algae produce more hydrogen, it is important to understand all the production pathways."

Single-celled green algae of the type Chlamydomonas are microscopically small organisms: ten of them fit side by side on a human hair. In some ways, microalgae are not so very different from higher plants, such as trees. For example, they also perform photosynthesis. Unlike land plants, they can use light energy for the production of molecular hydrogen (H2). Read more ..

Could Ethiopia’s Geothermal Exploration Relax Dam Plans?

Given that 85 percent of the country’s residents lack access to electricity, it is no surprise that Ethiopia has pursued an aggressive hydropower plan. But the Grand Renaissance Dam and similar projects are expected to create significant environmental and social disruptions,  problems that the former President Meles Zenawi both denied and defied.

But the Ethiopian Electric Power Corporation (EEPCO) recognizes the danger of relying too much on hydropower, which is an erratic and possibly endangered source of energy. While the country has the staggering potential to produce 45,000 megawatts of hydroelectricity, geothermal also offers promise – so much so that the World Bank has backed a plan to conduct preliminary exploration and drilling. Towards the end of last month, the Development Bank of Ethiopia unveiled plans to spend USD 20 million to explore sites in the country that have especially good geothermal potential. Read more ..

Wyden Floats Plan to Boost Geothermal Energy

Nesjavellr Geothermal Power plant

Pieces of new Senate Energy and Natural Resources Committee Chairman Ron Wyden’s (D-Ore.) legislative agenda are beginning to take shape. On Thursday, Wyden introduced a measure aimed at boosting development of geothermal energy by tweaking the leasing program for tracts of federal land to develop the renewable resource.

Currently the Interior Department holds lease sales, and then offers land on a “noncompetitive” basis if no bids are received, Wyden said. The bill, Wyden said, would expand access to land that’s offered outside of competitive lease sales.

“This legislation extends the authority for noncompetitive leasing in cases where a geothermal developer wants to gain access to Federal land immediately adjacent to land on which that developer has proven that there is a geothermal resource that will be developed. This will allow a geothermal project to expand onto adjacent land, if necessary, to increase the amount of geothermal energy it can develop. It will also add to the royalties and rents that the project pays to the U.S. Treasury,” he said in a statement Thursday. The measure is co-sponsored by Sen. Lisa Murkowski (R-Alaska), the Energy Committee’s top Republican, a long with a bipartisan mix of other lawmakers. Read more ..

A package of new bills introduced this week in the Senate seek to limit the Environmental Protection Agency’s regulatory reach and subject the agency to penalties for missing reporting deadlines.

Johanns took to the Senate floor Wednesday, saying the people of his home state are fed up with the EPA’s record during the Obama administration.

“And their message is very loud, clear, and unmistakable,” he said. “EPA is overreaching, overbearing, and overstepping boundaries that have long existed.” Republican angst has mostly been directed at the agency’s use of regulations and official memoranda to further the administration’s environmental agenda without congressional approval. Lawmakers also complained loudly after EPA’s regulatory agenda was released long after its statutory deadline. Read more ..

The UKH2Mobility project has released the results of its Phase 1 interim report, evaluating the benefits of hydrogen fuel cell electric vehicles (FCEVs) and paving the way for commercial rollout in the UK.

Launched in January 2012, this project brings together leading businesses from the automotive, energy, infrastructure, and retail sectors with government to provide a roadmap for the introduction of fuel cell electric vehicles (FCEVs) and hydrogen refuelling infrastructure in the UK. This will push well beyond the recently announced London Hydrogen Network Expansion (LHNE) project, the UK's first integrated hydrogen transport system in London and the South East.

Key findings from the interim report on Phase 1 include:

Up to 10% of new car customers will be receptive to fuel cell cars when they are first introduced, attracted by the newness of the technology and environmental benefits. Importantly, the study quantified the impact of non-financial decisions on the amount that consumers are willing to pay for an FCEV in different circumstances. Read more ..

The Past, Present and Future of Russian Energy Strategy

February 13th 2013

Gas pipe line

The future of Russia's ability to remain a global energy supplier and the strength the Russian energy sector gives the Kremlin are increasingly in question. After a decade of robust energy exports and revenues, Russia is cutting natural gas prices to Europe while revenue projections for its energy behemoth, Gazprom, are declining starting this year.

Russia holds the world's largest proven reserves of natural gas and continually alternates with Saudi Arabia as the top oil producer. The country supplies a third of Europe's oil and natural gas and is starting to export more to the energy-hungry East Asian markets. The energy sector is far more than a commercial asset for Moscow; it has been one of the pillars of Russia's stabilization and increasing strength for more than a century. The Kremlin has designated energy security as the primary issue for Russia's national security, especially since recent changes in global and domestic trends have cast doubts on the energy sector's continuing strength.

Throughout Russian history, the country's energy sector periodically has strengthened and weakened. Managing this cycle has been a centerpiece of Russia's domestic and foreign policy since czarist times. This historical burden now rests on Vladimir Putin's regime.  Read more ..

Researchers at the University of Souther California have developed a new lithium-ion battery design that uses porous silicon nanoparticles in place of the traditional graphite anodes to provide superior performance.

The new batteries—which could be used in anything from cell phones to hybrid cars—hold three times as much energy as comparable graphite-based designs and recharge within 10 minutes. The design, currently under a provisional patent, could be commercially available within two to three years.

"It's an exciting research. It opens the door for the design of the next generation lithium-ion batteries," said Chongwu Zhou, professor at the USC Viterbi School of Engineering, who led the team that developed the battery.

Solar Array

The world's cumulative solar photovoltaic (PV) electricity capacity surpassed 100 GW in 2012, achieving just over 101 GW, according to new market figures released by the European Photovoltaic Industry Association (EPIA).

The global capacity to harness the power of the sun produces as much electricity energy in a year as 16 coal power plants or nuclear reactors of 1 GW each. Each year, the world's PV installations reduce CO2 emissions by 53 million tons. The surpassing of the 100-GW mark occurred in a year of strong global PV development, with an estimated 30 GW connected to the grid and made operational in 2012 - roughly the same as the record-setting level of 2011. The results are preliminary, and the 30 GW figure could be increased by an additional 1 or 2 GW when final numbers come in. Final results for the year will be published in May 2013, in EPIA's annual Global Market Outlook for Photovoltaics 2013-2017' report.    

"No one would have predicted even 10 years ago that we would see more than 100 GW of solar photovoltaic capacity in the world by 2012," said EPIA President Winfried Hoffmann. "The photovoltaic industry clearly faces challenges but the results of 2012 show there is a strong global market for our technology. Even in tough economic times and despite growing regulatory uncertainty, we have nearly managed to repeat the record year of 2011."     Read more ..

Sen. Lisa Murkowski (R-Alaska) used the Republican weekly address Saturday to promote her new energy blueprint, a comprehensive plan that she argues will increase energy supplies and lower prices by removing government regulations.

“Energy is not a necessary evil. Energy is good. And that’s why it is in our national interest to make energy abundant, affordable, clean, diverse, and secure," Murkowski says in her address. "I believe that there’s a consensus around these five objectives, and our challenge now is to align federal policy with them."

In the plan, Murkowski calls for an end to regulations that Republicans believe will constrain the growth of coal-fired power plants, along with the immediate approval of the Keystone XL pipeline and the opening of the Arctic National Wildlife Refuge to drilling. Other components include expediting liquefied natural-gas exports, promoting the use of small modular nuclear reactors, and creating a new quasi-federal agency for nuclear waste management.

"Every recommendation in my blueprint is associated with a clear goal for the year 2020," Murkowski said. "We can end our dependence on OPEC oil. We can help make renewable energy more competitive, build on our efficiency gains, and re-establish the supply chain for critical minerals." The plan also calls for the government to beef up cybersecurity for energy infrastructure and toughen criminal statutes for those who would target the nation's power grid.

The Alaska senator argues that adopting her proposals would have far-reaching, positive impacts across the American economy. "The ideas in my blueprint would create new jobs, generate new revenues, and slash our dependence on foreign energy. They would shore up our security and strengthen our economy. They would help us minimize the impacts of energy development and reduce the emissions that are blamed for climate change,” Murkowski said. Read more ..

Major Oil Company Breaks with Trade Group Over SEC Disclosure Lawsuit

February 8th 2013

Oil Refinery

Norwegian oil-and-gas giant Statoil is distancing itself from petroleum industry litigation to scuttle Securities and Exchange Commission rules (SEC) that will force oil and mining companies to disclose payments to foreign governments.

The multinational company’s position has delighted human-rights groups that back the rule, and activists are using Statoil’s stance to try and build support for the controversial regulation that’s required under the 2010 Dodd-Frank financial law.

“Statoil has not supported the lawsuit initiated by [the American Petroleum Institute]; in fact, Statoil has explicitly withheld support for the litigation. As you know, we have not taken an active stand regarding the lawsuit, but chose to communicate our view on the new rule to the SEC, internally in the API and in other relevant fora,” the company said in a late January letter to the watchdog group Global Witness.

Interior Department to Investigate Coal Exports

February 8th 2013

Coal Train

The Interior Department will investigate whether mining companies are gaming the federal government by skirting royalty payments, a pair of senior senators announced Friday. The agency is looking into whether mining firms lowball the value of coal excavated from federal lands to minimize the fees they pay the government.

“The Department shares your concern that this matter should be taken seriously and be thoroughly investigated to determine if there is any merit to the allegations contained in the December 4, 2012, Reuters articles referenced in your letter,” Interior Secretary Ken Salazar wrote in a letter Thursday to Senate Energy and Natural Resources Committee Chairman Ron Wyden (D-Ore.). Reuters said mining companies are underreporting the price of coal at mine sites — where royalties are assessed — then selling it to marketers that they oftentimes own. Reuters said those intermediaries then ship the coal abroad, where they fetch higher prices. Read more ..

Norway is Leader in Developing Battery-Powered Ships

February 7th 2013

Turkish car ferry

The Norwegian shipping industry is teaming up to take a leading role in developing battery-powered ships. The first four hybrid vessels will start to sail in 2013/14.

In 2015, the world largest fully electric ferry, will start to regularly cross Norway's largest fjord.

“15 years ago, the Norwegian cluster was looking into opportunities for gas-fuelled ships. Today, Norway is the front-runner when it comes to LNG-fuelled ships. Electricity stored in batteries on board ships is another opportunity in the future energy mix and another technology race has started. We have been running that track for a while already,” said Narve Mjøs, Director of Battery Projects in DNV and in charge of a DNV seminar that hosted 120 managers representing Norway's entire maritime cluster.

World's First Shipping Container Bridge Over Tel Aviv's Trash Mountain

February 6th 2013

Shipping Container Bridge

A new bridge called ECOtainer made from recycled shipping containers will render “trash mountain” unrecognizable to residents of Tel Aviv. The Hiriya landfill just outside of Tel Aviv shut down in 1998 after becoming the repository for 25 million tons of waste. More mountain than landfill, Hiriya has since been transformed into one of the world’s most successful reclamation projects.

Already the methane emitted from Hiriya is harvested to power a nearby factory and the surrounding area is being converted into an urban park that is safe for a variety of outdoor recreational activities. Now Yosef Messer Architects have won the Econtainer Bridge Competition, which may result in the construction of a bridge made of recycled shipping containers linking Arial Sharon Park with the main thoroughfare leading to Tel Aviv.

Gas Shortages Highlight Pakistan's Energy Crisis

February 5th 2013

Gas Station Lines

Long lines of cars waiting to fill their tanks have become a familiar sight in Pakistan's capital. A struggling economy means gas is in short supply, and prices are going up, fuel and electricity shortages are affecting the lives of ordinary citizens. At Islamabad gas stations, this is what it looks like on Wednesdays. People are stocking up, because on Thursday, Friday and Saturday, stations close and there is no gas.  

In recent years, when gasoline prices rose, millions of drivers converted their cars to run on Compressed Natural Gas, or CNG. But now that's in short supply. Law lecturer Syed Shabat Ali says the problem is getting worse. "This is affecting the lives of people very badly. For example, I come on the days when CNG is available and I get in the queue and then I have to wait two or three hours. I am sorry to say it is also disturbing the psyche of the people," he said. "People are losing confidence in our governments, because government is taking no interest towards a very serious problem that people are facing." Read more ..

Prediction Tool Reduces Traffic Stalls

February 4th 2013

Traffic Jam

Less traffic congestions is what a recently concluded pilot project in Cologne aimed at. In the project, the City of Cologne and IBM collaborated in developing algorithms that reduce traffic congestion by means of traffic forecasts.

In order to generate short-time traffic forecasts, the system processed huge numbers of traffic data. According to IBM, with an accuracy of better than 90 percent, the results were very encouraging.

The City disposes of a traffic management centre with 20 traffic cameras at critical locations and about 150 measurement points. Hitherto however, no computer-based traffic analysis was available. The purpose of the pilot project was to find an answer to the question how traffic optimizing by means of traffic prediction could help to reduce the number of congestions. Traffic experts believe that precise short-time predictions and traffic situation analysis can detect imminent traffic densification in urban areas before they materialize and counteract by means of appropriate measures.

‘Virtual Chimney’ Fences Could Reduce Airport Pollution Impact

February 3rd 2013

Frankfurt Airport

Simple ‘blast’ fences called baffles could deliver improvements in air quality for people living near airports, new research has found. Placed behind a runway, the baffles could serve as a ‘virtual chimney’, funnelling emissions from aircraft engines upwards where they can disperse more effectively, thereby reducing the environmental impact on people living nearby.

Prototype baffles have been tested by a team of researchers from Manchester Metropolitan University, Cranfield University, the University of Southampton and the University of Cambridge, with funding from the Engineering and Physical Sciences Research Council (EPSRC).

After preliminary wind tunnel testing of various baffle shapes carried out by Cranfield University, an array of three rows of baffles was tested using laser scanning (Lidar, which is the optical equivalent of Radar) and chemical sensor techniques at Cranfield Airport in Bedfordshire. This demonstrated that the aircraft exhaust plume could be made to leave the ground within the airport’s boundary fence, using prototype baffles of less than a man’s height and constructed out of low-cost agricultural windbreak netting on lightweight frames.

Google Makes a Push on Electric Utilities

February 2nd 2013

Google is launching an effort aimed at getting electric utilities and states to change how they charge consumers for electricity. The Internet giant is putting money behind the push, announcing Monday that it awarded a $2.65 million grant to grantmaking group Energy Foundation.

Google said policy reforms would incentivize the use of “smart grid" technology, encourage greater energy conservation and reduce power blackouts. “We’ve seen big changes in recent years to the way we watch TV, use phones, read and listen to music, yet how we use electricity hasn’t changed much in decades,” Michael Terrell, senior policy counsel of energy and sustainability with Google, wrote Monday on the Internet giant’s blog.

Google wants a heavier use of “smart” grid technology, a term that refers to devices and “smart” electric meters that communicate through Internet protocol — rather than proprietary — communication systems. Smart grid technology would enable consumers to see their energy use data in real time, most commonly through a website provided by the electric utility, or a home energy management device.
