Scotland's tidal energy potential is greater than a nuclear power plant
January 20, 2014 09:09 AM - ClickGreen Staff, ClickGreen
Renewable tidal energy harnessed from a single stretch of water off the northern tip of Scotland could produce enough energy to power half of the nation, engineers say.
Oil production in Greenland? Maybe not.
January 20, 2014 07:22 AM - EurActiv
None of the oil companies that have a license to drill in the seas surrounding Greenland have applied for one in 2014, according to the environment NGO Greenpeace. Oil companies that want to drill in Greenland will have to apply before 1 February, but according to Greenland's Mining Agency, no applications have been received thus far. This will be the 3rd year in a row that no company has expressed interest in oil drilling around the Arctic country.
Wastewater to power project planned in DC
January 18, 2014 09:13 AM - Joanna M. Foster, Think Progress via Care2
When the D.C. Water and Sewer Authority was first planning to build its Blue Plains wastewater treatment facility back in the 1930s, it seemed logical to choose a site that would minimize the cost of pumping water uphill. That's why the facility, which today serves over 2 million people in D.C., Maryland, and Virginia and treats around 370 million gallons of wastewater a day, is located at the lowest point in all of the District of Columbia. But the 150-acre facility, on the banks of the Potomac River, is now confronting the downside of what was once a strategic siting decision — the entire facility is extremely vulnerable to the flooding predicted by future sea level rise.
Finding Arctic Cyclones
January 17, 2014 12:18 PM - Pam Frost Gorder, Ohio State University
From 2000 to 2010, about 1,900 cyclones churned across the top of the world each year, leaving warm water and air in their wakes — and melting sea ice in the Arctic Ocean. That's about 40 percent more of these Arctic storms than previously thought, according to a new study of vast troves of weather data that previously were synthesized at the Ohio Supercomputer Center (OSC). A 40 percent difference in the number of cyclones could be important to anyone who lives north of 55 degrees latitude — the area of the study, which includes the northern reaches of Canada, Scandinavia and Russia, along with the state of Alaska.
Washington DC leaking all over
January 17, 2014 09:56 AM - Tim Lucas, Duke University
More than 5,893 leaks from aging natural gas pipelines have been found under the streets of Washington, D.C., by a research team from Duke University and Boston University. A dozen of the leaks could have posed explosion risks, the researchers said. Some manholes had methane concentrations as high as 500,000 parts per million of natural gas -- about 10 times greater than the threshold at which explosions can occur.
Chemicals of Emerging Concern (CECs) identified in sewage sludge
January 16, 2014 04:17 PM - Richard Harth, Arizona State University
Thousands of chemicals serving a variety of human needs flood into sewage treatment plants once their use life has ended. Many belong to a class of chemicals known as CECs (for chemicals of emerging concern), which may pose risks to both human and environmental health. Arjun Venkatesan and Rolf Halden of Arizona State University's Biodesign Institute have been tracking many of these chemicals outlining a new approach to the identification of potentially harmful, mass-produced chemicals, describing the accumulation in sludge of 123 distinct CECs.
Sydney Coastal Waters See Successful Seaweed Transplant
January 16, 2014 03:14 PM - Allison Winter, ENN
In its natural environment, seaweed plays a major role in marine ecosystems. Not only does the plant provide nutrients and energy for organisms up the food chain, but these plants also provide shelter and habitat for many different species. So when 70 kilometers of seaweed vanished from the Australian Coast in the 1970s and 1980s due to high levels of sewage, we would expect to see some dramatic environmental problems. But thanks to recent recovery efforts, a habitat-forming species known as crayweed is making a successful comeback in Sydney's coastal waters.
The girth of a tree
January 15, 2014 04:54 PM - Robin Blackstone, ENN
Thank goodness human growth rates don't match that of trees. For if it did then we would tip the scales of well over a ton by the time we reach retirement! Consider this new research from the Smithsonian Tropical Research Institute (STRI) recently published in the journal Nature. According to the new study, trees put on weight faster and faster as they grow older. Because most trees' growth accelerates as they age this suggests that large, old trees may play an unexpectedly dynamic role in removing carbon from the atmosphere.
From Waste to Food to Fuel: Rice Production and Green Charcoal in Senegal
January 15, 2014 12:54 PM - Andrew Alesbury, Worldwatch Institute
Inadequate management of human waste is a dire problem in much of the developing world. Swelling urban populations can make matters worse by exposing increasingly dense populations to illnesses carried by human waste.
The problem with older thermostats - Mercury
January 15, 2014 07:51 AM - NRDC
NRDC Study Shows More Than 1.8 Million Thermostats Containing 8 Tons of Mercury Need Safe Recycling In Illinois. The state should raise collection goals for mercury-laden thermostats to avoid contaminating the environment. There are more than 1.8 million thermostats containing eight tons of mercury in Illinois homes and buildings, according to a study by the Natural Resources Defense Council and Clean Water Fund, which are calling for stronger state rules this year to speed up safe recycling of these thermostats.
