21 May 2013: Large Majority of Americans
Believe Global Warming Should be a Priority

Roughly 70 percent of Americans say global warming should be a priority for President Obama and Congress and 61 percent support requiring fossil fuel companies to pay a carbon tax that would be used to help reduce the national debt, according to a new survey by the Yale Project on Climate Change Communication. In a national survey conducted in April, 87 percent of respondents said that the president and Congress should make developing clean sources of energy a priority, 68 percent favored regulating carbon dioxide as a pollutant, and 71 percent supported providing tax rebates for people who buy solar panels and energy-efficient vehicles. Seventy percent said global warming should be at least a “medium” priority, while 28 percent said it should be a low priority. The poll showed that 7 in 10 Americans support funding more research into green energy sources. One surprising finding was that half of those polled had never heard of the Keystone XL pipeline, a controversial 1,711-mile proposal that would carry tar sands oil from Alberta to refineries in Texas.

17 May 2013: ‘Artificial Forest’ Nanosystem
Mimics Photosynthesis, Researchers Say

U.S. scientists have developed what they say is the first integrated nanosystem capable of replicating the process of photosynthesis, a sort of “artificial forest” that could one day lead to the production of hydrogen that could be used to power fuel cells. Composed of nanowire structures — including silicon “trunks” and titanium oxide “branches” — the system mimics the role played by chloroplasts in promoting photosynthesis in green plants. By assembling the “trees” in a dense array, resembling a miniature forest, the network lowers sunlight reflection and provides more surface area for hydrogen-producing reactions, the scientists say. “We’ve integrated our nanowire nanoscale heterostructure into a functional system that mimics the integration in chloroplasts and provides a conceptual blueprint for better solar-to-fuel conversion efficiencies in the future,” said Peidong Yang, a chemist with the Lawrence Berkeley National Laboratory and co-author of the study, published in the journal NANO Letters. The lab of Daniel Nocera at Harvard University is doing related research into so-called artificial leaves.

16 May 2013: Scientist’s U.S. Road Trip
Reveals Unexpected Methane Emissions

Methane measurements collected during a scientist’s road trip across the U.S. indicate that local emissions of the potent greenhouse gas are higher than previously known in many regions. Using a gas chromatograph mounted to the roof of a rented camper, Ira Leifer of the University of California, Santa Barbara, collected air samples from Florida to California, finding the highest methane concentrations in areas with significant refinery activity — such as Houston, Texas — and in a region of central California with oil and gas production. He found that methane concentrations exceeded the levels estimated by the U.S. Department of Energy, particularly in areas near industrial fossil fuel extraction sites. The results point to the importance of targeting these “fugitive” methane emissions in parallel with efforts to reduce CO2 emissions. Leifer's findings were published in the journal Atmospheric Environment.

09 May 2013: Third Coal Export Proposal
Falls By Wayside in Pacific Northwest

A large U.S. pipeline developer has dropped plans to build a $200-million coal export facility in northern Oregon, the third major terminal proposal to be shelved or canceled in the Pacific Northwest. Officials at Houston-based Kinder Morgan say the Columbia River site could not optimally accommodate the 30 million tons of coal that were expected to run through the site annually, largely for markets in Asia. While the company said the decision had nothing to do with public opposition to transporting massive amounts of coal from the Powder River Basin in Wyoming to the coast, critics of the plan say growing protests affected the decision. “If that site didn’t meet their physical constraints, they would have known that… years ago when they proposed this,” Brett VandenHeuvel, director of the group Columbia Riverkeeper, told the Los Angeles Times. Thousands of residents have signed petitions to block the project, citing concerns that the coal trains would cause pollution from coal dust and create traffic congestion. Three other coal export projects — two in Washington and one in Oregon — are still on the table.

07 May 2013: Battery-Equipped Wind Turbine
Better Integrates Green Energy Onto Grid

General Electric recently introduced a wind turbine equipped with a storage battery, creating a type of “hybrid” turbine that industry leaders hope will improve the integration of intermittent energy sources onto the grid and reduce the costs of wind power. The GE battery is able to store less than one minute of the turbine’s energy potential, but by pairing the battery with advanced wind-forecasting algorithms, wind farm operators could guarantee a certain amount of power output for up to an hour, MIT’s Technology Review reports. Even small amounts of storage are able to compensate for rapid changes in output from renewable sources — such as when wind speeds fall — and thus exert less stress on conventional power plants in responding to the variability of wind and solar. This flexibility will become increasingly important as renewable energy accounts for a greater share of grid capacity, since major shifts in output can trigger voltage problems or blackouts.

The solar cells simultaneously power four batteries with the storage capacity of an electric car, which allows the plane to fly in darkness. The airplane, with a 208-foot wingspan, is made of lightweight, carbon fiber materials that help it conserve energy, but its spindly structure also makes the plane unable to fly in windy or stormy conditions. Project organizers hope the five-leg journey — which will include stops in Dallas, St. Louis, and Washington and end in New York — will demonstrate the feasibility of long-distance air travel without fuel.

03 May 2013: Seawater Energy Technology
Is Focus of Pilot Project in China

The U.S. defense and aerospace giant, Lockheed Martin, is partnering with a major Chinese company to build a pilot project off the southern Chinese coast that will use temperature differentials between the deep and shallow ocean to generate electricity. The technology, known as ocean thermal energy conversion (OTEC), uses the heat from warm surface waters to boil a fluid with a low boiling point, such as ammonia, producing steam to drive turbines. Colder water is then pumped from 2,500 to 3,000 feet under the sea, which condenses the steam into liquid; the liquid can then be boiled again to produce more steam and power. Lockheed Martin and its Chinese Partner, the Beijing-based Reignwood Group, said their project — the largest OTEC plant ever built — will produce 10 megawatts of power when it opens in 2017, enough to provide electricity for a large, planned resort that Reignwood is building.

01 May 2013: Program Targeting Diesel
Emissions Will Be Cut by 70 Percent

A federal program that has cleaned up or removed 50,000 high-polluting diesel engines from U.S. roads is scheduled to be cut by 70 percent under President Barack Obama’s latest budget. The program eliminated 230,000 tons of soot and smog-causing pollutants, slashed more than two million tons of carbon dioxide emissions, and saved 205 million gallons of fuel. But the program’s budget has faced steady cuts in recent years, falling from $50 million in fiscal year 2011, to $20 million in 2013, to a proposed $6 million in fiscal year 2014. The diesel cleanup program has succeeded in removing only a fraction of the 11 million dirty, pre-2006 diesel vehicles on the road. But environmentalists say that the program has been successful in helping clean the air in low-income communities that often are situated near ports, highways, and other areas with high diesel traffic.

30 Apr 2013: U.S. Government Backs
New Way to Make Diesel from Biomass

The U.S. Energy Department is investing up to $4.3 million in a pilot biomass project that will convert the stalks and leaves of corn plants into diesel fuel using a new chemical process. The pilot plant in Indiana will be run by Mercurius Biofuels, whose goal is to convert the corn biomass into fuel at prices cheap enough to compete with petroleum. Mercurius’s process uses recyclable acids to break down cellulose and make a chemical called chloromethylfurfural, which can be converted into diesel or jet fuel. The inventor of the process, Mark Mascal, a professor of chemistry at the University of California, Davis, says the technology makes more efficient use of the carbon in cellulose and avoids the significant releases of carbon dioxide involved in a common way of making fuel from biomass — converting the cellulose into sugar and fermenting it to make ethanol. Mercurius says the corn stalks and leaves can be converted into chloromethylfurfural at small, local plants and then shipped to larger refineries to make diesel fuel, thus avoiding the high cost of shipping the biomass itself to a central refinery.

26 Apr 2013: NASA Tests Affirm Viability
Of Biofuel-Powered Commercial Jets

In recent test flights, NASA researchers have confirmed that commercial airliners can safely fly on an alternative jet fuel blend and that under some conditions the biofuel mix produced 30 percent fewer emissions than

typical jet fuel. After flying DC-8 aircraft using a biofuel blend containing 50 percent camelina plant oil, scientists from Langley Research Center in Virginia say they observed no noticeable difference in the jets’ engine performance. And specially equipped planes that measured the exhaust emissions from the jets’ contrails found the biofuel blend produced fewer emissions, according to NASA. “In terms of these fuels being acceptable for use in commercial aircraft, they’re quite acceptable,” Bruce Anderson, a senior research scientist at Langley Research Center, told the Associated Press. “But we’re still digging into the data.” But while camelina plant oil might eventually emerge as an attractive biofuel source, since it can be grown in arid regions, researchers noted that it is currently cost-prohibitive. Currently, Anderson said, camelina oil costs about $18 per gallon, compared to $4 per gallon for typical jet fuel.

22 Apr 2013: Green Energy Investments
To Triple by 2030, Analysis Predicts

Annual investment in renewable energy is predicted to triple between now and 2030, according to a report by Bloomberg New Energy Finance. In an analysis of several factors shaping the global energy future —
First Solar Panels
First Solar Inc.
including economic conditions, market demands, and the evolution of technologies — the group predicted that annual spending may increase from $190 billion last year to $630 billion by 2030. A key factor in the growth is the plunging cost of wind and solar energy, which in the short term has bankrupted many manufacturers. The Bloomberg report also forecast significant growth in hydropower, geothermal, and biomass sources of energy. In the most likely scenario, 70 percent of new power generation capacity between 2012 and 2030 would come from renewable sources — with wind and solar accounting for 30 and 24 percent, respectively — while only 25 percent would come from fossil fuel sources.

19 Apr 2013: New Solar Cell Process
Achieves Record Efficiency, MIT Says

Researchers at the Massachusetts Institute of Technology (MIT) say they have achieved a major breakthrough in the conversion of sunlight into electricity, surpassing what was long believed to be an absolute limit to the efficiency of solar cell devices. While the process used in the typical photovoltaic (PV) cell process knocks loose one electron inside the PV material to produce an electrical current — but wastes any excess energy carried by a photon — a new process described in the journal Science utilizes that extra energy to produce two electrons. That exploits so-called singlet exciton fission and makes the process far more efficient, creating more electrical energy. An exciton is the excited state of a molecule after absorbing energy. While the material used in the organic solar cell, known as pentacene, was previously known to produce two so-called excitons from one photon, researchers say this is the first time anyone has demonstrated the principle within a photovoltaic device. While the typical solar panel achieves efficiencies no greater than 25 percent, the scientists believe this process can be utilized to achieve efficiencies of more than 30 percent.

Interview: Using Citizen Power
To Fund a U.S. Solar Revolution

Billy Parish is the president of Mosaic, an Internet “crowdfunding” service that lets individual investors put their money into commercial solar projects and earn a rate of return that

currently beats anything offered by a bank. This month, California regulators authorized Mosaic to offer up to $100 million in loans for solar projects. Its first loan under that authorization, $157,750 to install a 114-kilowatt array on the Ronald McDonald House in San Diego, was funded within six hours by 171 investors. Parish, 31, a co-founder of the Energy Action Coalition, decided after the failure of the 2009 climate talks in Copenhagen that the best way to drive a clean energy transition was to dive into the renewable energy business. In an interview with Yale Environment 360, Parish talks about why his generation has pursued environmental goals through entrepreneurship, how crowdfunding can fuel the solar revolution, and how he discovered “that sweet spot where making money and doing good overlap.”

16 Apr 2013: U.S. Offshore Seismic Testing
Threatens Many Marine Species, Study Says

The proposed use of seismic air guns in the search for offshore oil and gas reserves along the U.S. East Coast could injure or kill nearly 140,000 marine animalsannually and disrupt the vital activities of other species,

a new study says. The seismic testing, in which guns filled with compressed air are fired repeatedly over deep-sea target areas to provide energy companies an image of the deposits below, would threaten marine species of all sizes, from tiny fish eggs to large whales, according to an analysis by the conservation group Oceana. The group said that the powerful air gun blasts, which it describes as “100,000 times more intense than a jet engine,” could disturb the breathing, feeding, and mating habits for dolphins and whales and cause injury or death to endangered species such as the North Atlantic right whale. The analysis comes as the U.S. Interior Department’s Bureau of Ocean Energy Management completes a study of the potential impacts of seismic activities from Delaware to Florida. Oil industry officials point to other research that shows seismic testing is unlikely to threaten marine mammals.

15 Apr 2013: Renewable Energy Generated
70 % Of Portugal’s Electricity in Quarter

Portugal generated more than 70 percent of its electricity from renewable sources of energy during the first quarter of 2013, a record amount fueled largely by hydroelectric and wind energy sources, according to a report from the country’s grid operator. Hydroelectric generation provided 37 percent of the nation’s electricity from January to March, a 312-percent increase compared to last year, while wind energy accounted for 27 percent, a 60-percent increase, Redes Energéticas Nacionais (REN) reported. While favorable weather helped drive the record levels in wind and hydroelectric power, the results also reflect Portugal’s investment in renewable energy projects — including wind farms, hydroelectric, solar and wave energy — and an improved electricity grid that allows green energy providers to connect into the system. Nearly 45 percent of the country’s electricity will come from green sources this year compared with just 17 percent five years ago, ThinkProgress reports.

09 Apr 2013: Artificial Leaf’s ‘Self Healing’
Could Expand Its Practical Use Globally

The so-called “artificial leaf,” a solar cell being developed by MIT and Harvard scientists to produce low-cost electricity, is now capable of “self healing” the damage that occurs during energy production, clearing

a hurdle to deploying the device in the developing world, the researchers say. When dipped into water, the leaf — which is actually a catalyst-coated wafer of silicon about the size of a playing card — is able to split water into its two components, hydrogen and oxygen, which can then be collected and used as fuel to power a fuel cell. “Surprisingly, some of the catalysts we’ve developed for use in the artificial leaf device actually heal themselves,” Daniel Nocera of Harvard, the leader of the research team, told a meeting of the American Chemical Society. While earlier versions of the device required pure water, the self-healing properties enable users to operate the leaf using impure, bacteria-contaminated water. According to the researchers, the leaf is now able to generate 100 watts of electricity 24 hours a day with just a quart of water.

08 Apr 2013: Project to Test Promise of
Small, Vertical-Axis Wind Turbines

A wind farm being planned in a remote Alaska village will seek to demonstrate that small, vertical-axis turbines can produce more energy than conventional wind turbines and cause less environmental damage.

While the turbines used in most standard wind farm projects can produce turbulence that actually decreases the output of the turbines downstream, John Dabiri, a California Institute of Technology professor, says that small, vertical-axis turbines can create a wake that actually boosts the output of adjacent turbines if positioned strategically. In addition, the smaller turbines can be placed closer together without causing aerodynamic interference, are cheaper to produce, and are less likely to kill birds, Dabiri told MIT’s Technology Review. Dabiri says he hopes his Alaska project, which could eventually include 70 turbines in the village of Igiugig, can generate as much energy as the diesel generators currently used by the community. Critics argue that the vertical-axis turbines aren’t as efficient as conventional turbines.
