• Water securityFracking would pose no danger to water supplies: Research

    One of the primary concerns of those who oppose the development of shale gas by hydraulic fracturing is that creation of new fractures in the earth could cause fracking fluids to leak into, and contaminate, underground freshwater aquifers. Potential future fracking activity in the United Kingdom is unlikely to pose a pollution danger to overlying aquifers, new research from a leading academic suggests.

  • Water securityGroundwater quality changes alongside the expansion of hydraulic fracturing and horizontal drilling

    New research demonstrates that groundwater quality changes alongside the expansion of horizontal drilling and hydraulic fracturing but also suggests that some potentially hazardous effects may dissipate over time. The research is the first to analyze groundwater quality in the Cline Shale region of West Texas before, during, and after the expansion of hydraulic fracturing and horizontal drilling.

  • Emerging threatsA single oil field a key culprit in global ethane gas increase

    A single U.S. shale oil field is responsible for much of the past decade’s increase in global atmospheric levels of ethane, a gas that can damage air quality and impact climate, according to a new study. The researchers found that the Bakken Formation, an oil and gas field in North Dakota and Montana, is emitting roughly 2 percent of the globe’s ethane. This is about 250,000 tons per year.

  • EnergyFossil fuels could be phased out worldwide in a decade: Study

    The worldwide reliance on burning fossil fuels to create energy could be phased out in a decade, according to energy experts. The experts analyzed energy transitions throughout history, and argue that only looking toward the past can often paint an overly bleak and unnecessary picture. The transition from wood to coal in Europe, for example, took between 96 and 160 years, whereas electricity took 47 to 69 years to enter into mainstream use. The future could be different: the scarcity of resources, the threat of climate change, and vastly improved technological learning and innovation could greatly accelerate a global shift to a cleaner energy future.

  • Manmade earthquakesTexas earthquake may have been manmade, but more data needed to assess hazards

    The most comprehensive analysis to date of a series of earthquakes that included a 4.8 magnitude event in East Texas in 2012 has found it plausible that the earthquakes were caused by wastewater injection. The findings also underscore the difficulty of conclusively tying specific earthquakes to human activity using currently available subsurface data.

  • Water securityOil, gas wastewater disposal pollutes surface water, harm waterways

    Unconventional oil and gas (UOG) operations combine directional drilling and hydraulic fracturing, or “fracking,” to release natural gas and oil from underground rock. This process results in in water pollution which may increase endocrine disrupting chemicals (EDCs) in surface and ground water, exposing populations living near these operations to increased risk of disease. High levels of EDC activity were found in the surface water near a hydraulic fracturing wastewater disposal facility in West Virginia. Approximately 36,000 of these disposal wells are currently in operation across the United States.

  • Emerging threats Renewables and nuclear no substitute for carbon dioxide disposal

    Oxford scientist argues that there are only two things we can affect with policies today that will really matter for peak warming: reducing the cost of large-scale capture and disposal of carbon dioxide, and maximizing the average rate of economic growth we achieve for a given rate of emission in the meantime.

  • EarthquakesFracking linked to most induced earthquakes in western Canada

    A survey of a major oil and natural gas-producing region in Western Canada suggests a link between hydraulic fracturing or “fracking” and induced earthquakes in the region. The study’s findings differ from those reported from oil and gas fields in the central United States, where fracking is not considered to be the main cause of a sharp rise in induced seismicity in the region. Instead, the proliferation of hundreds of small earthquakes in that part of the United States is thought to be caused primarily by massive amounts of wastewater injected back into the ground after oil and gas recovery.

  • Nuclear accidentsFukushima five years on: Three lessons from the disaster

    It has been five years since the emergency sirens sounded at Japan’s Fukushima Daiichi power plant following the massive 2011 earthquake and subsequent devastating tsunami. The partial meltdown of three reactors caused approximately 170,000 refugees to be displaced from their homes, and radiation releases and public outcry forced the Japanese government to temporarily shut down all of their nuclear power plants. On the fifth anniversary of the partial meltdown at Japan’s Fukushima Daiichi Power Plant, Stanford’s Rodney Ewing says we should rethink our language, reassess natural disaster risks, and appreciate the links between nuclear energy and renewables.

  • Food securityResources used for biofuel reduce resources available for food production

    As strategies for energy security, investment opportunities and energy policies prompt ever-growing production and consumption of biofuels like bioethanol and biodiesel, land, and water that could otherwise be used for food production increasingly are used to produce crops for fuel. A new study shows about a third of the world’s malnourished population could be fed by using resources now used for biofuel production.

  • EnergyWorld economy unlikely to stop relying on fossil fuels: Study

    On the heels of last year’s historic climate agreement in Paris, a new study concludes that fossil fuel consumption is likely to grow without clear and decisive global action to put an adequate price on carbon dioxide emissions and increased clean energy technology.

     

  • EnergyRapid, affordable energy transformation in U.S. possible

    The United States could slash greenhouse gas emissions from power production by up to 78 percent below 1990 levels within fifteen years while meeting increased demand, according to a new study. The study used a sophisticated mathematical model to evaluate future cost, demand, generation, and transmission scenarios. It found that with improvements in transmission infrastructure, weather-driven renewable resources could supply most of the nation’s electricity at costs similar to today’s.

  • Carbon captureBreakthrough in continuous monitoring of CO2 leaks from carbon storage sites

    Underground storage of CO2 produced from fossil fuel burning, rather than releasing it into the atmosphere, could play an important role in suppressing climate change. Ensuring that the CO2 does not leak from the storage site is key – but the high number of surveys necessary to make sure there is no CO2 leak  makes this a costly endeavor. A team of Japanese researchers may have found a means of achieving easier and lower-cost monitoring for leaks of CO2 stored in underground reservoirs.

  • Emerging threatsGlobal learning required to prevent carbon capture, storage from being abandoned

    Governments should not be abandoning carbon capture and storage, argues a Cambridge researcher, as it is the only realistic way of dramatically reducing carbon emissions. Instead, they should be investing in global approaches to learn what works – and what doesn’t.

  • FrackingToxins found in fracking fluids and wastewater: Study

    In an analysis of more than 1,000 chemicals in fluids used in and created by hydraulic fracturing (fracking), researchers found that many of the substances have been linked to reproductive and developmental health problems, and the majority had undetermined toxicity due to insufficient information. The researchers say that further exposure and epidemiological studies are urgently needed to evaluate potential threats to human health from chemicals found in fracking fluids and wastewater created by fracking.
