PG&E to pay $1.6 billion in gas explosion settlement
The California Public Utilities Commission (CPUC) has levied the largest penalty in the agency’s history on Pacific Gas and Electric Company (PG&E), ordering the company to pay $1.6 billion for failures which led to a 2010 natural gas pipeline explosion in San Bruno. The explosion killed eight people and destroyed or damaged thirty-eight homes.Afaulty weld on the pipeline caused the explosion and the resulting fire. The company may also owe an additional $1.13 billion in federal criminal fines connected to the blast, and has committed to spend $2.8 billion in reassessing pipeline safety.

California not the only state to face water shortage
Over the past two weeks, California’s long drought — and Governor Jerry Brown’s mandatory water conservation rules — have captured the headlines. As the country keeps an eye on how Californians will adapt to the new reality of water conservation, other states must prepare to maintain the sustainability of their own water supplies. “As far as other states, if they haven’t seen it [water shortages] in the past, it’s something they will see in the future,” says a water policy analyst in Los Angeles.

Critics: PG&E downplays quake risk to Diablo Canyon nuclear plant
Since the Diablo Canyon nuclear power plant in California was opened by Pacific Gas and Electric Co. (PG&E) in 1985, geologists have discovered three fault lines nearby, which could threaten the plant. The three faults are capable of quakes even stronger than the one which ravaged the Napa Valley last year, and critics of PG&E say the company has been minimizing the risks the three faults pose. The company rejects the criticism. The critics are now suing to company to force it to reapply for an operating license – with the information about the three faults included in the application.

Scientists develop deep borehole disposal (DBD) method to deal with nuclear waste
Technologies which will enable nuclear waste to be sealed five kilometers below the Earth’s surface could provide a safer, cheaper and more viable alternative for disposing of the U.K.’s high level nuclear waste. Scientists calculate that all of the U.K.’s high level nuclear waste from spent fuel reprocessing could be disposed of in just six boreholes five kilometers deep, fitting within a site no larger than a football pitch. The concept — called deep borehole disposal — has been developed primarily in the United Kingdom, but is likely to see its first field trials in the United States next year.

Big data technology helps identify best river locations for hydro-power generation
A new technology has the potential to revolutionize the sourcing of renewable energy from rivers. The software app automatically selects appropriate locations in U.K. rivers to site a large range of micro renewable hydro-power turbines in these rivers, and determines the environmental sensitivity of the location.

San Diego to build largest ocean desalination plant in Western Hemisphere
San Diego County, California will soon become home to a $1 billion desalination plant which would supply drinking water to residents currently having to cut their water consumption by as much as 25 percent in response to the state’s current drought. Small ocean desalination plants already operate throughout the state, but the facility being built in San Diego will be the largest ocean desalination plant in the Western Hemisphere, producing roughly fifty million gallons of drinking water a day.

Cyber espionage campaign, likely sponsored by China, targets Asian countries: FireEye
FireEye has released a report which provides intelligence on the operations of APT 30, an advanced persistent threat (APT) group most likely sponsored by the Chinese government. APT 30 has been conducting cyber espionage since at least 2005, making it one of the longest operating APT groups that FireEye tracks. APT 30 targets governments, journalists, and commercial entities across South East Asia and India.

Extreme geohazards: Reducing disaster risk, increasing resilience
Extreme hazards — rare, high-impact events — pose a serious and underestimated threat to humanity. The extremes of the broad ensemble of natural and anthropogenic hazards can lead to global disasters and catastrophes. Because they are rare and modern society lacks experience with them, they tend to be ignored in disaster risk management. While the probabilities of most natural hazards do not change much over time, the sensitivity of the built environment and the vulnerability of the embedded socio-economic fabric have increased rapidly.

Virtual guard detects real-time leaks in water, oil-, or gas pipes
Often, water, gas, or oil distribution networks suffer from leaks in storage tanks, pumping failures, or illegal tapping. In order to prevent losses which typically result, researchers designed a virtual guard which immediately detects abnormalities in any type of duct. Through the laws of physics and application of a mathematical model of fluid mechanics, the device calculates when an irregularity occurs on site, and issues an alert.

Doubts about burying CO2 underground to address climate change
Burying the greenhouse gas carbon dioxide, a byproduct of burning fossil fuels, has been mooted as one geoengineering approach to ameliorating climate change. To be effective, trapping the gas in geological deposits would be for the very long term — thousands of years. Now, researchers have reviewed the risk assessments for this technology, suggesting that a lack of knowledge means we should be cautious of turning to this method rather than finding sustainable ways to reduce emissions at their source.

Joplin, Missouri hospital re-built to withstand powerful tornadoes
In 2011 St. John’s Medical Center in Joplin, Missouri was devastated by one of the most ferocious tornadoes in U.S history. Today, Mercy Hospital Joplinstands on the site of the former hospital, occupying a new structure designed to survive future tornadoes, with windows that can withstand 250-mile-per-hour winds. The buildingis covered in concrete and brick paneling, and houses an underground bunker where generators and boilers are kept.

Underground impact of a missile or meteor hit
When a missile or meteor strikes the earth, the havoc above ground is obvious, but the details of what happens below ground are harder to see. Physicists have developed techniques that enable them to simulate high-speed impacts in artificial soil and sand in the lab, and then watch what happens underground close-up, in super slow motion. The research, funded by the Defense Threat Reduction Agency, the research may ultimately lead to better control of earth-penetrating missiles designed to destroy deeply buried targets such as enemy bunkers or stockpiles of underground weapons.

Renewables win, coal loses as shift in electricity generation lead to net job growth in energy
In the four years following the 2008 recession, the coal industry lost more than 49,000 jobs, while the natural gas, solar, and wind industries together created nearly four times that amount, according to a new study. A county-by-county geographical analysis of the losses and gains shows that few new jobs were added in regions hardest hit by coal’s decline, particularly counties in southern West Virginia and eastern Kentucky.

Californians mull life with less water
Following Californian governor Jerry Brown’s decision to enforce mandatory water restrictions for the first time in history, Californians are planning for changes in their daily lives. Experts say, though, that California cannot resemble its drier neighbor, Arizona. “Without water, you can’t live in California,” Stanford University’s Bill Whalen. “It ties into the California psyche. They have plush lawns and nice gardens that require lots of water. They have the ocean and Lake Tahoe skiing. You have a nice car. You want it clean. You need water. You can’t have California agriculture without water. You lose the nation’s salad bowl.”

DHS S&T selects UNC as coastal resilience center of excellence
The DHS Science and Technology Directorate (S&T) the other day announced the selection of the University of North Carolina at Chapel Hill as the lead institution for a new DHS Coastal Resilience Center of Excellence (COE). S&T will provide the Coastal Resilience COE with an initial $3 million grant for its first operating year. The DHS Coastal Resilience COE will bring together university students and professors, DHS and other federal agencies, private sector partners, the first responder community, and other COEs to collaboratively address the unique challenges facing communities across the United States that are vulnerable to coastal hazards, including hurricanes and flooding.
