• Standardizing small, self-sustaining electric microgrids

    When Department of Energy and Oak Ridge National Laboratory researchers talk about “islanding,” or isolating, from the grid, they are discussing a fundamental benefit of microgrids — small systems powered by renewables and energy storage devices. The benefit is that microgrids can disconnect from larger utility grids and continue to provide power locally.

  • Hungarian red mud spill did little long-term damage

    The aftereffects of the 2010 red mud spill that threatened to poison great swathes of the Hungarian countryside have turned out to be far less harmful than scientists originally feared. The disaster happened when weeks of heavy rain caused a dam to collapse at a containment facility in Ajka in Western Hungary. It released around a million cubic meters of toxic sludge into the Torna-Marcal river system, onto the Hungarian plain and ultimately into the Danube. The mud, a byproduct of refining aluminum from bauxite ore, was dangerously alkaline, extremely salty and contained potentially toxic metals like chromium and vanadium.

  • Lights out: Experts say instability of world’s power supplies must be urgently addressed

    A new study reveals the urgent need to address instabilities in the supply of electrical power to counteract an increase in the frequency and severity of urban blackouts. The work builds on previous studies which examined a sharp increase in electrical usage over recent years, and warned the world to prepare for the prospect of coping without electricity as instances of complete power failure become increasingly common.

  • Major American cities manage water supply better

    In an effort to address environmental factors, population growth, and technological factors, many American cities are taking steps to practice better water conservation efforts, after decades of largely ignoring steps that could be taken. These practices have brought average water use per person each day from fifty-five gallons to something closer at times to thirty to thirty-five gallons.

  • A major cyberattack causing widespread harm to national security is imminent: Experts

    A new report found that more than 60 percent of the roughly 1,600 computer and Internet experts surveyed on the future of cyberattacks believe a nationwide cyberattack is imminent. They did so in response to the question: “By 2025, will a major cyberattack have caused widespread harm to a nation’s security and capacity to defend itself and its people?” The experts also warn about the risks to privacy which will accompany a growing focus on cybersecurity.

  • Coastal towns build resilience to prepare for future storms

    Sea Bright, New Jersey is one of several communities affected by Superstorm Sandy which is actively building resiliency against the next major storm. The town, set on a narrow strip of sand between the Atlantic Ocean and the Shrewsbury River, frequently floods, and during Sandy, its entire downtown business district was damaged, as were 75 percent of the town’s homes.

  • Upgrading infrastructure could reduce future flood damage

    From 1980 to 2007, about 90 percent of all global disasters were caused by flooding either by rain, tsunami, hurricane, or some other natural event. At the same time, the American Society of Civil Engineer’s 2013 Report Card for America’s Infrastructure gave the country a dismal D+. The group said $3.6 trillion was needed by 2020 to address the most serious problems. In Colorado, the report card says, 70 percent of major roads are poor or mediocre and 566 bridges are structurally deficient. A new study argues that the severe flooding that devastated a wide swath of Colorado last year might have been less destructive if the bridges, roads, and other infrastructure had been upgraded or modernized.

  • Texas acts to reduce number of man-made earthquakes

    The number of disposal wells in Texas has surged along with the number of drilling projects. Texas has more than 3,600 active commercial disposal wells. In 2013, the Railroad Commission approved 668 disposal well permits, twice the number of approvals in 2009. The growing number of disposal wells corresponds with an increase in earthquakes in communities where such seismic activity rarely existed.Officials in Texas have now taken steps to reduce the number of earthquakes caused by wells drilled for the disposal of oilfield waste.

  • Georgia Tech releases 2015 Emerging Cyber Threats Report

    In its latest Emerging Cyber Threats Report, Georgia Tech warns about loss of privacy; abuse of trust between users and machines; attacks against the mobile ecosystem; rogue insiders; and the increasing involvement of cyberspace in nation-state conflicts.

  • Many victims of Hurricane Sandy are still waiting for government aid

    It has been two years since Hurricane Sandy destroyed thousands of homes and businesses along the Jersey Shore yet many affected homeowners are still waiting for federal and state aid to rebuild. Of the $3.26 billion the U.S. Department of Housing and Urban Development (HUD) has provided to New Jersey, only $802 million has been paid out as of 30 September. The federal government’s first allocation of Sandy funds to New Jersey came seven months after the storm. The state has yet to issue any of the $1.46 billion approved by HUD in May, and New Jersey officials expect a final round of $880 million next spring.

  • State regulators discuss the connection between fracking and earthquake

    Regulators from states with significant petroleum and natural gas exploration activities met last week in Columbus, Ohio as part of the 2014 Interstate Oil and Gas Compact Commission conference.One key topic of discussion at the conference wasthe potential implications of a study which found that numerous, unnoticeable earthquakes in Harrison County, Ohio, likely were linked to oil and natural gas exploration. 190 of the quakes which ranged from magnitude 1.7 to 2.2, occurred in the thirty-nine hours after fracking activity occurred at one well in late September and early October 2013.

  • States invest in resilience in the face of mounting extreme-weather challenges

    Months after Superstorm Sandy devastated the New York coast line, Governor Andrew Cuomo’s Office of Storm Recovery launched a $17 billion strategy to transform the state’s infrastructure. Project Reimagining New York for a New Reality sought to make the state’s transportation networks, energy supply, coastal protection efforts, weather warning systems, and emergency management more resilient. The strategy is just one example of a trend in investments toward resilience efforts post Hurricane Katrina, Irene, Lee, and Sandy.

  • Building a network of canals to save Boston from sea level rise

    By the end of the century, sea-level rise on the U.S. east coast is predicted to reach six feet, so city planners in Boston recently met to discuss how to live with rising waters along the city’s historic streets. One suggestion is to turn Boston’s Back Bay district into a network of canals. The canals would alleviate sea-level rise by draining water into lower-lying back alleys and some main streets, but the proposed plan would have to contend with freezing temperatures in the winter.

  • Effective, inexpensive method to detect natural gas pipeline leaks

    Major leaks from oil and gas pipelines have led to home evacuations, explosions, millions of dollars in lawsuit payouts, and valuable natural resources escaping into the air, ground and water. Scientists say they have developed a new software-based method that finds leaks even when they are small, which could help prevent serious incidents — and save money for customers and industry.

  • South Florida wants to secede from Florida over sea level rise

    When people talk of “secession” in the United States they typically have Texas, Vermont, or the former Confederate states in mind, and the reasons for driving secession typically have to do with politics or money. Not anymore. The city of South Miami earlier this month passed a resolution which called for southern Florida to secede from the rest of the state, citing climate change as the reason. There are many differences between north and south Florida: South Florida is largely urban and politically tends to lean left, while the north is mostly rural and much more conservative. If south Florida reminds people of New York, the Florida panhandle resembles Alabama. Then there is this: The northern part of the state is, on average, 120 feet above sea level, but much of the southern section averages only fifteen feet above sea level. South Floridian say that the state government in Tallahassee ignores the perils of sea level rise, which are particularly acute in south Florida, so the time has come to separate from the aloof north.
