7 July 2015, Bloomberg Business, Refracking Is the New Fracking: The technique itself is nothing new. Oil crews across the world have been schooled on its simple principles for generations: Identify aging, low-output wells and hit them with a blast of sand and water to bolster the flow of crude. The idea originated somewhere in the plains of the American Midwest, back in the 1950s. But as today’s engineers start applying the procedure to the horizontal wells that went up during the fracking boom that swept across U.S. shale fields over the past decade, something more powerful, more financially rewarding is happening. The short life span of these wells, long thought to be perhaps the single biggest weakness of the shale industry, is being stretched out. Early evidence of the effects of restimulation suggests that the fields could actually contain enough reserves to last about 50 years, according to a calculation based on Wood Mackenzie Ltd and ITG Investment Research data.

7 July 2015, Renew Economy, Network charges may penalise uptake of battery storage, as well as PV: The trend among some electricity networks to penalise or discourage the uptake of rooftop solar by imposing fixed tariffs or additional fees is now extending to battery storage, with one network accused of trying to lift charges to households with storage even though they are reducing peak demand. In an analysis of recent tariff proposals by South Australia Power Networks, which included a since-rejected attempt to apply a surcharge to solar households, the Australian PV Institute says SAPN now seems intent on penalising households that install battery storage, despite their obvious network benefits. “SAPN admit that batteries will reduce network peaks but still wish to charge PV households that install batteries as if they are increasing the peak,” the APVI, an independent institute, says in a newly released discussion paper.

1 July 2015, The Guardian, Climate change a security risk second only to terrorism, says defence report. Defence white paper consultation report flags consequences of environmental pressures as a significant security risk for Australia. The Abbott government’s energy white paper made headlines for its curiousreluctance to mention climate change – but the looming defence white paper may prove to be a different story. A report on community consultations associated with the defence white paper flags the consequences of climate change, extreme weather events and environmental pressures as a significant security risk for Australia – second only to the risks posed by terrorism. “Many people suggested [climate change] would lead to an increased need for humanitarian and disaster relief activities, including by armed forces,” the report released on Wednesday said. “Some people also noted that climate change and resource stresses, such as food and water shortages, could drive unregulated cross-border movements of people.” The consultations also unearthed “considerable interest in evolving the ADF [Australian defence force] to reduce its greenhouse gas emissions and manage its environmental impact.” Read More here

1 July 2015, The Guardian, More evidence that global warming is intensifying extreme weather: A new study finds that global warming is causing weather whiplash. Just this week, a new article appeared in the journal Nature that provides more evidence of a connection between extreme weather and global warming. This falls on the heels of last week’s article which made a similar connection. So, what is new with the second paper? A lot. Extreme weather can be exacerbated by global warming either because the currents of atmosphere and oceans change, or it can be exacerbated through thermodynamics (the interaction of heat, energy, moisture, etc.). Last week’s study dealt with just the thermodynamics. This week’s study presents a method to deal with both. The authors, Daniel Horton, Noah Diffenbaugh and colleagues used a new technique to tease apart the complex influences of warming on changes to atmospheric circulation.
