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

Enlarge

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.

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.

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.

Improve Efficiency of Solar Energy Systems

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

Cabbage white butterfly
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.

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.

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.

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.

trend in overall coal production, the U.S. Energy Information Administration reports. Mountaintop removal (MTR) mines have recently been subjected to additional stringent regulations.

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.

Water use in fracking operations in the U.S.
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.

Households and businesses with solar panels deliver greater benefits to utility companies than they receive through programs

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.

22 Jun 2015: Researchers Look to Design of
Owl Wings to Make Quieter Wind Turbines

A new type of coating for wind turbines inspired by the shape of owl wings may dramatically cut noise associated with onshore

wind farms, according to research from the University of Cambridge. 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.

questions — both technical and ethical — surrounding any attempt to revive extinct species. In a Yale Environment 360 interview, Shapiro, associate director of the Paleogenomics Institute at the University of California at Santa Cruz, explains why she believes new gene-editing technology could benefit critical ecosystems and living species that are now endangered. “We are in the midst of an extinction crisis,” she says. “Why would we not use whatever technologies are available to us, assuming we can go about doing it in a reasonable and ethical way?”

of carbon dioxide into the atmosphere, an ecosystem service worth at least $5 billion, Georgia State University economists found. 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.
