Wind and solar power, paired with storage, would be cost-effective way to power grid
Renewable energy could fully power a large electric grid 99.9 percent of the time by 2030 at costs comparable to today’s electricity expenses, new research says; a well-designed combination of wind power, solar power, and storage in batteries and fuel cells would nearly always exceed electricity demands while keeping costs low, the study authors found

Marines looking for solar energy in combat outposts
The Office of Naval Research (ONR) is looking to the sun for energy in an effort to help Marines do away with diesel-guzzling generators now used in combat outposts; the Renewable Sustainable Expeditionary Power (RSEP) program seeks to create a transportable renewable hybrid system that can provide Marines with electricity for a 15-day mission without relying on fuel resupply convoys that often become targets for adversaries

Responding to future oil spills: lessons learned from Deepwater Horizon
A special collection of articles about the Deepwater Horizon oil spill provides the first comprehensive analysis and synthesis of the science used in the unprecedented response effort by the government, academia, and industry;with the benefit of hindsight and additional analyses, these papers evaluate the accuracy of the information that was used in real-time to inform the response team and the public

Fracking in Michigan
In hydraulic fracturing, large amounts of water, sand and chemicals are injected deep underground to break apart rock and free trapped natural gas; though the process has been used for decades, recent technical advances have helped unlock vast stores of previously inaccessible natural gas, resulting in a fracking boom; researchers are examining the benefits of fracking for Michigan

Synthetic fuels could entirely eliminate U.S. need for crude oil, create new economy
The United States could eliminate the need for crude oil by using a combination of coal, natural gas, and non-food crops to make synthetic fuel, a team of researchers has found; besides economic and national security benefits, the plan has potential environmental advantages; because plants absorb carbon dioxide to grow, the United States could cut vehicle greenhouse emissions by as much as 50 percent in the next several decades using non-food crops to create liquid fuels

Student invents a wireless vibration sensor which harvests energy from earthquakes
A wireless vibration sensor being developed by an engineering student could provide a low-cost solution for engineers to monitor the damage of buildings affected by earthquakes; currently, no sensor exists in the marketplace which does not rely on batteries or electricity supply to run

Learning the lessons of the BP oil spill
In an attempt to limit the harm of the Deepwater Horizon oil spill in the Gulf of Mexico in 2010, three million liters of dispersant were used to dissipate the oil; on the surface the damage seems limited, but the seabed is covered with a thick layer of gunk; scientist from around the world are now working on models that can be consulted by decision makers when there is another oil spill disaster

Combining CO2 storage with enhanced oil recovery can aid U.K. economy
Combining carbon storage with enhanced oil recovery techniques in key fields could generate up to 2.7 billion pounds in extra economic output; if a combination of carbon storage and enhanced recovery techniques is fully exploited, it is estimated that nineteen potentially suitable oil fields on the U.K. Continental Shelf (UKCS) could contribute 15 percent of all UKCS oil production by 2030

Chemists convert greenhouse gas to fuel
What if you could take greenhouse gas and convert it to fuel for an energy-hungry world? Scientists, using modern genetics, accomplished exactly this; the researchers’ findings are just a first step toward converting carbon dioxide, one of the most abundant emissions from fossil fuel use, into usable hydrocarbons

New fluorescence technology pinpoints oil leaks at sea
Cambridge Consultants uses fertility monitor technology in oil leak early warning system; the company has built an oil spill detection technology platform which is capable of detecting the natural fluorescence of even tiny amounts of oil in or on water

In Pennsylvania, the U.S. mecca of fracking, more scientific research is urged
Hydraulic fracturing or fracking is a controversial method to extract natural gas or petroleum from subterranean shale by using pressurized water to blast it open; proponents of fracking have noted its potential for helping the United States achieve energy independence while also stimulating the economy and creating jobs; these proponents have met stiff resistance from environmental groups that claim fracking can result in air and water pollution and have adverse human health effects

Stunt kites raise wind power to another level
Researchers are sending stunt kites into the skies to harness the wind and convert the kinetic energy generated into electricity; the kites fly at a height of 300 to 500 meters, positioned to be caught by strong winds; cables, about 700 meters in length, tether the kites to vehicles and pull them around a circuit on rails; a generator then converts the kinetic energy of the vehicles into electricity

CIA-commissioned climate change report outlines perils for U.S. national security
U.S. national security leaders believe that the accelerating pace of climate change will place severe strains on U.S. military and intelligence agencies in coming years; the reason, according the National Research Council, the U.S. top scientific research body: climate changes will trigger increasingly disruptive developments around the world; a 206-page National Research Council study, commissioned by the CIA and other U.S. intelligence services, concludes that states will fail, large populations subjected to famine, flood, or disease will migrate across international borders, and national and international agencies will not have the capacity or resources to cope with the resulting conflicts and crises

Scientists resurrect process to convert sugar directly to diesel
A long-abandoned fermentation process once used to turn starch into explosives can be used to produce renewable diesel fuel to replace the fossil fuels now used in transportation; the retooled process produces a mix of products that contain more energy per gallon than ethanol that is used today in transportation fuels and could be commercialized within 5-10 years

Hurricane Sandy offered support for reliance on nuclear power
A Scientific American writer is impressed with the way nuclear power facilities were able safely to withstand the wrath of Hurricane Sandy; the lesson he draws from this experience: “Global warming is increasing the probability and destructiveness of extreme weather events like Sandy. (I don’t see the point of dithering over this claim any more.) The last thing we should do in the face of this threat is abandon nuclear energy. If anything, we need more nuclear power, not less, to curb global warming”
