26 Aug 2015: U.S. Shale Gas Production
Expected to Fall for First Time, Report Says

Natural gas production from all seven major shale formations in the U.S. is projected to drop next month for the first time since

Monthly change in shale gas production
the shale gas boom began in earnest roughly a decade ago, according to an analysis from the U.S. Energy Information Administration. Major shale regions produced gas at a record-high rate of 45.6 billion cubic feet per day in May, but that rate is expected to drop to 44.9 billion cubic feet per day in September, the report says. It attributes the decline to existing, legacy wells becoming significantly less productive and a substantial drop in the number of drilling rigs in each of the seven major shale regions since September 2014. New wells are being established, the EIA notes, but they are not producing enough natural gas to offset expected declines from legacy wells.

costs for solar photovoltaic systems, according to an analysis by the U.S. Department of Energy's Lawrence Berkeley National Laboratory. Residential rooftop solar panels in the U.S. cost 40 cents per watt less than the same systems in 2013, and prices for non-residential systems fell by 70 cents per watt. In the first half of this year, costs in a number of large markets fell by an additional 20 to 50 cents per watt, the report says. Photovoltaic equipment costs have remained relatively stable since 2012, so the lower prices are primarily due to reductions in "soft" costs such as marketing, labor, permits, and inspections, analysts say.

11 Aug 2015: Cost of Producing Wind Power
Reached a New Low in the U.S. Last Year

The cost of generating wind power in the U.S. fell to its lowest level ever last year, according to a report from the Department of Energy. Utility companies purchased wind power for 2.35 cents per kilowatt-hour on average last year, making the price of wind energy competitive with conventional power sources in many parts of the country. Wind power now meets on average 4.9 percent of the nation's electricity demand, the DOE analysis found, and nine states used wind to produce more than 12 percent of their electricity. Iowa and South Dakota produced more than a quarter of their electricity from wind, Kansas generated roughly 22 percent from wind, and Texas remained the leading state for wind installations in 2014. With a total installed capacity of 66 gigawatts, the U.S. now ranks second only to China in wind power capacity.

Remaining Coal Power Plants, Officials Say

New Zealand will close its last remaining coal plants and rely even more heavily on renewable sources for its electricity needs,

the country's energy minister announced Thursday. New Zealand already has the fourth-largest share of renewable electricity generation in the world, with roughly 80 percent of its energy needs met by renewables. The final two coal-fired power plants will shut down by December 2018, according to the utility company running the plants, which cited changing market conditions that have made coal power unnecessary in New Zealand. The nation has been using coal to fill gaps in dry years, when hydropower could not meet the grid's demand. But recent investments in wind and, particularly, geothermal energy have made that stopgap measure unnecessary, the energy minister said. The country has pledged ahead of the Paris climate summit to cut emissions to 30 percent below 2005 levels by 2030.

06 Aug 2015: Mimicking Butterfly Wings Can
Improve Efficiency of Solar Energy Systems

Solar-concentrating photovoltaic systems can produce nearly 50 percent more power by mimicking the V-shaped wing

formation certain butterflies exhibit before take-off, say researchers at the University of Exeter. The cabbage white butterfly warms its muscles before flight by placing its wings in the shape of a "V" to maximize the concentration of solar energy onto its thorax. This behavior, known as reflectance basking, increases the butterfly's thorax temperature by roughly 13 degrees F compared to flat wings, the researchers found. When reflective panels are arranged around a concentrating photovoltaic system in the same way, this wing-like configuration increases the power-to-weight ratio of the solar energy system by 17-fold, making it vastly more efficient, the researchers explain in the journal Scientific Reports. The team showed that replicating the single layer of highly reflective scale cells found in the butterfly wings could also improve power-to-weight ratios of solar concentrators.

05 Aug 2015: Emissions From U.S. Power
Plants Reached 27-Year Low, Report Says

Electric power plants in the U.S. emitted less carbon dioxide in April than they have in any month since April 1988 — a 27-year low — according to an analysis by the Energy Information Administration. The report said the electric power sector has made major strides in improving efficiency and lowering its carbon footprint, producing significantly more electricity while lowering CO2 emissions. Renewable energy production has more than doubled since 1988, the use of natural gas to produce electricity has more than tripled, and coal consumption has decreased by 17 percent, the EIA report says. Natural gas plants are now about 25 to 30 percent more efficient than coal plants in terms of power generation, and they emit 71 to 79 percent less carbon dioxide than coal plants.

If Alaska’s Pebble Mine Proceeds


The proposed Pebble Mine in southwestern Alaska is a project of almost unfathomable scale. If the copper- and gold-mining project proceeds, the mine would cover 28 square miles and require the construction of the world’s largest earthen dam — 700 feet high and several miles long — to hold back a 10-square-mile containment pond filled with up to 2.5 billion tons of sulfide-laden mine waste. All this would be built not only in an active seismic region, but also in one of the most unspoiled and breathtaking places on the planet — the headwaters of Bristol Bay, home to the world’s most productive salmon fishery. In a photo essay, landscape photographer Robert Glenn Ketchum documents the lands and waters at risk from the project, whose fate is currently wending its way through the courts.

27 Jul 2015: President Obama Announces
Major New Limits on Interstate Ivory Trade

President Obama has announced strict new limits aimed at stemming the global ivory trade which, when implemented,

would nearly ban all ivory trade within the United States. The measures also include new restrictions on when ivory can be exported to other countries. “We’re proposing a new rule that bans the sale of virtually all ivory across state lines,” Obama said at a press conference in Kenya on Saturday. Current laws in the U.S. are aimed at controlling the import and export of ivory, while allowing some legal trade among states — a loophole that many illegal ivory dealers have used to their advantage. The new regulation, expected to be finalized later this year, would restrict ivory trade between states to items that are over 100 years old or contain only very small amounts of ivory. The U.S. is estimated to be the world's second largest ivory market, with sales outpacing all nations except China.

They took advantage of that ability to create a synthetic coral that can bind and remove mercury pollution in water. The coral-like structure is covered with self-curling nanoplates made of aluminum oxide — a chemical compound that can collect heavy metals. The scientists found that the synthetic coral structure could bind mercury 2.5 times more efficiently than aluminum oxide particles alone. According to the World Health Organization, up to 17 in every thousand children living in areas relying on subsistence fishing showed cognitive declines caused by eating mercury-contaminated fish.

microorganisms that can grow in a variety of environments and laboratory settings — require less fertilizer, water, land, and herbicides than corn, and thus could prove to be an environmentally friendly alternative for livestock feed, researchers say. The materials used in the new study were remnants of algae grown and processed for other applications, such as cosmetics, cooking oil, and biofuels, and would otherwise have been burned as waste. The researchers found that even these pre-processed leftovers were able to provide the same amount of protein as corn, along with slightly more fat. Cattle in the study readily ate the algae at a variety of concentrations and maintained their body weight as well as corn-fed cattle. Researchers say the algal meal could be priced to compete with corn and could be on the market by 2016.

Interview: The High Environmental
Cost of Illicit Marijuana Cultivation

As some U.S. states move to legalize marijuana, one issue has been largely ignored in the policy debates: the serious

environmental effects of the marijuana industry. A new paper co-authored by ecologist Mary Power details many of those impacts by focusing on marijuana cultivation in California, where most of the marijuana consumed in the U.S. is grown. In an interview with Yale Environment 360, Power describes how California growers siphon off scarce water resources, poison wildlife, and erode fragile soils. What’s needed, she contends, is legalization of marijuana at the federal level, which would likely drive down marijuana prices. “As long as there is a market that will pay enough to compensate for the brutally hard work they do to grow this stuff in forested mountains,” she says, “then it will keep growing.”

In the new study, the researchers found that they could modify the PEI-enhanced buckyballs to capture carbon in lower-temperature environments. The advance may open the door to fine-tuning the enhanced buckyballs for a variety of carbon capture projects, the researchers say.

Australian Prime Minister Tony Abbott said that the CEFC should invest in new and emerging technologies, and that wind and small-scale solar projects should instead be supported by the free market. Currently, one-third of CEFC funding, which totals roughly $10 billion, goes to solar projects, the majority of which are small-scale. The funding ban could increase prices for small-scale solar projects such as rooftop photovoltaic panel installations, especially for low-income households, renters, and public housing tenants. The ban on these investments is the latest in a series of actions by the Abbott government to make cuts in environmental initiatives, including two failed attempts to abolish the CEFC.

trend in overall coal production, the U.S. Energy Information Administration reports. Mountaintop removal (MTR) mines have recently been subjected to additional stringent regulations. For example, MTR operations planning to discard excess rock and soil in streams must now secure extra permits from the Environmental Protection Agency. Tennessee is considering banning some types of MTR mining altogether, and a federal stream protection rule expected to be proposed this summer could place additional limits on the practice. Lower demand for U.S. coal in general can be attributed to competitive natural gas prices, renewable energy growth, flat electricity demand, and environmental regulations, the EIA says.

Geological Survey. The increased water demand is attributed to the development of new, water-intensive technologies that target fossil fuels in complicated geological formations, the researchers say. The amount of water used varies greatly with location, the study found. A fracking operation in southern Illinois, for example, can use as little as 2,600 gallons of water each time an oil or gas well is fracked. That figure jumps to more than 9 million gallons in Pennsylvania, Ohio, and south and eastern Texas. Fracking is often concentrated in arid regions and could exacerbate existing water shortages, especially as water requirements for fracking continue to increase. Most of the water used for fracking is disposed deep underground, removing it from the water cycle.

Net metering programs credit solar panel owners at a fixed rate — equal to or less than the retail price of electricity — for providing the excess power they generate to the grid. Utility companies have been fighting those credits in recent years, saying that solar panel owners don't pay a fair share of grid maintenance and other overhead costs. However, all 11 studies showed that solar panel owners provide net benefits to their respective utility systems, Environment New York says, including reduced capital investment costs, lower energy costs, and reduced environmental compliance costs. The median value of solar power across all 11 studies was roughly 17 cents per unit, compared to the nation’s average retail electricity rate of about 12 cents.

The scientists found that an owl's flight feathers have a microscopic down-like covering and numerous other intricate design details that smooth the passage of air over the wing, scattering sound as the owl flies. To replicate the structure, the researchers looked at designing a covering that would scatter the sound generated by a turbine blade in the same way. Early tests of their prototype material, a 3D-printed plastic coating, demonstrated that it could significantly quiet wind turbines without any appreciable impact on aerodynamics. Since wind turbines are heavily braked in order to minimize noise, the new technology could mean that turbines could spin at much higher speeds, producing more energy while making less noise.

Their conclusion about the monetary benefit of those forest protections is based on a new method they derived for valuing services such as carbon capture, conservation, and improvements in air and water quality. Instead of relying on modeling alone, the new method uses interviews and on-the-ground data to see how conservation programs affect human behavior and impact ecosystems. By combining the two types of information — environmental models and social science data — public officials can gain more realistic insights into how a particular policy might affect the environment and the people who interact with it, the researchers write in the Proceedings of the National Academy of Sciences.

There are roughly 85 million unused phones in the U.K. alone, the researchers note, and replacing the gold they contain — not to mention copper, silver, and other rare metals — would cost nearly $170 million and release an equivalent of 84,000 tons of CO2. Moving to a "cloud-based" system where heavy computing is done on remote servers would allow manufacturers to produce less-complex phones that are designed to last longer and require fewer valuable metals, the analysis found.

01 Jun 2015: Six Major Fossil Fuel Companies
Call for Governments to Set Carbon Price

Six leading oil and gas companies have called on governments to enact a carbon-pricing system, saying this would be the most effective way to cut greenhouse gas emissions. The chief executives of Total, Statoil, Royal Dutch Shell, BG Group, BP, and Eni, in a joint letter to the head of the UN Framework Convention on Climate Change, said that governments should use regulatory measures to discourage carbon-intensive energy options and to level the playing field for all energy sources, both renewables and fossil fuels. The executives said the companies are willing to do their part, but that governments need to provide a clear, stable, and long-term policy framework. Total chief Patrick Pouyanne said in a news conference that a carbon price of roughly $40 per ton is needed to spur the replacement of coal-fired power stations, which produce twice as much CO2 as those that use natural gas. And a price of $80 to $100 per ton, he said, would justify investing in carbon capture and storage systems.

14 May 2015: Biologically Inspired Coating
Will Improve Solar Panels, Researchers Say

Key characteristics of moths’ eyes, which are anti-reflective, and lotus leaves, which are water-repellant, inspired a new type of glass coating that could significantly improve the efficiency of solar panels, say researchers at Oak Ridge National Laboratory. The extremely durable coating can be customized to be fog-resistant, anti-reflective, and superhydrophobic — meaning it repels water drops so efficiently that they barely make contact with the solar panel surface, literally bouncing off and carrying away dirt and dust that hamper performance. The key component is a nanostructured layer of glass film that, under a microscope, has a porous texture resembling coral, which helps the solar cells absorb more light, the researchers say. Reflecting less sunlight means a 3 to 6 percent increase in light-to-electricity conversion efficiency and power output, studies show. The coating can be fabricated using standard industry techniques, the researchers say, making it easy and inexpensive to scale up and incorporate in current products.

But some metals that have become more common in technology over the last two decades, such as rare earth metals, are available almost entirely as byproducts, the researchers say. "You can't mine specifically for them; they often exist in small quantities and are used for specialty purposes," said Yale scientist Thomas Graedel. "And they don't have any decent substitutes."

Because most plastics accumulate in landfills and remain intact for decades or longer, some manufacturers have begun producing plastics with proprietary blends of additives that are supposed to make the materials biodegradable, and a number of countries have adopted legislation promoting the use of those additives. But in laboratory tests, researchers found the plastics with biodegradation-promoting additives fared no better than conventional plastics in any of three different disposal scenarios — simulated landfill conditions, compost, and soil burial for three years. Previous research looked at plastics buried in soil for 10 years, the authors note, and found that only 5 percent of the so-called biodegradable plastic decomposed.

If Indonesian forestry industries operated at capacity, 41 percent of the wood supply would be illegal, the analysis found, and if companies were to go forward with plans for new mills, the supply would be 59 percent illegal. The source of this illegal wood is unclear, but the report suggests it is likely harvested by clear-cutting natural forests for new oil palm and pulp plantations. Part of the problem, the report says, is that Indonesia's sanctioned forestry plantations — the country's primary source of legal wood — are not currently sustainable because they are producing wood at only half the predicted rate.
