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.

Oil sands-derived fuels will release on average 20 percent more carbon into the atmosphere over their lifetime — and possibly up to 24 percent more — depending on how they are extracted and refined, the study says. Methane emissions from tailing ponds and carbon emissions from land disturbance and field operations also contribute to the higher carbon footprint. "This is important information about the greenhouse gas impact of this oil source, and this is the first time it has been made available at this level of fidelity," said Hao Cai, the Argonne researcher who led the study. Roughly 9 percent of the total crude processed in U.S. refineries in 2013 came from the Canadian oil sands, and that percentage is projected to rise to 14 percent by 2020.

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.

The spores pack more energy, pound for pound, than other materials used in engineering for moving objects, said researcher Ozgur Sahin, who co-authored the study published in Nature Communication. When evaporation energy is scaled up, he says, it could one day produce electricity from giant floating power generators that sit on bays or reservoirs or rotating machines like wind turbines that sit above water.

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.

Smog-Forming Compounds Than Expected

Refineries that produce ethanol fuel may be releasing much larger amounts of smog-forming compounds than researchers and government agencies had suspected, according to a new study in the Journal of Geophysical Research: Atmospheres. Airborne measurements downwind from an ethanol refinery in Illinois show that, compared to government estimates, ethanol emissions are 30 times higher and emissions of all volatile organic compounds (VOCs), which include ethanol, are five times higher. Producing one kilogram of the fuel at the Illinois refinery emits 170 times more ethanol than what comes out of a vehicle burning the same amount, the study says. Along with nitrogen oxides, VOCs can react with sunlight to form ground-level ozone, the main component of smog. Renewable fuel standards mandate that gasoline burned in the U.S. contains 10 percent ethanol — an attempt to reduce greenhouse gas emissions and petroleum imports while boosting the renewable fuels sector.

more stress on power grids and energy prices than scientists had previously thought, according to research from the University of California, Berkeley. Looking at households throughout Mexico, the researchers found that, in the warm areas, air conditioning use increases steadily with income — 2.7 percent per $1,000 of annual household income. The team used those findings, along with population, climate, and household income projections, to model future growth in air conditioner use across the globe. Conservatively, they say, the model predicts near-universal saturation of air conditioning in all warm areas within just a few decades. That will place enormous stress on the energy infrastructure of some nations — India, for example, is already experiencing blackouts during surges in power use — and will drive up energy costs worldwide.

studies to the contrary, state officials have remained skeptical of the link between this seismic boom and oil and gas activity. That ended last month with the announcement by the Oklahoma Geological Survey that oil and gas wastewater injection wells were, indeed, the “likely” cause of “the majority” of that state’s earthquakes. Oklahoma geologist Todd Halihan, who has examined this issue, welcomed the announcement. In an interview with Yale Environment 360, Halihan outlines some ways that the abnormal seismic activity in Oklahoma might be tamped down. But he also explains why he believes the problem has no quick or easy fixes.
