Seahawks vs. Broncos: Sustainability Highlights for the Teams and Super Bowl XLVIII
January 29, 2014 09:18 AM - Allison Winter, ENN

With the Seattle Seahawks getting ready to play the Denver Broncos this weekend in Super Bowl XLVIII, here at ENN, we are not only focused on the game, but we are also interested in the sustainability efforts of the stadiums and the teams. As for this year's Super Bowl, MetLife Stadium boasts that it is the first stadium in the world to earn the title of "Certified Green Restaurant" stadium from the Green Restaurant Association (GRA).

Beaver, Dam it!
January 20, 2014 09:32 AM - Enn Staff, The Ecologist

As climate change brings more rain, there will be more catastrophic flooding; flooding of crops, homes and businesses, particularly in urban areas where there is simply no place for the water to go. One British writer has identified the beaver as the would-be hero to restore hydrological normalcy. Louise Ramsey writes about the beaver in Britain where reintroductions of the rodent have shown the vital role they once had in reducing flooding and how they could take up that mantle once more.

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.

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.

Giant wave of understanding in South China Sea

Their effect on the surface of the ocean is negligible, producing a rise of just inches that is virtually imperceptible on a turbulent sea. But internal waves, which are hidden entirely within the ocean, can tower hundreds of feet, with profound effects on the Earth's climate and on ocean ecosystems. Now new research, both in the ocean and in the largest-ever laboratory experiments to investigate internal waves, has solved a longstanding mystery about exactly how the largest known internal waves, in the South China Sea, are produced. The new findings come from a team effort involving MIT and several other institutions, and coordinated by the Office of Naval Research (ONR).

Annual home checkup should include a radon test
January 8, 2014 12:49 PM - Robin Blackstone, ENN

Because 21,000 Americans die each year from radon related lung cancer the EPA recommends an annual testing of radon in the home. By making January “Radon Action Month” homeowners can protect their family from this leading cause of lung cancer among non-smokers and DIY test kits are as low as $10.

Renewables Now Cheaper Than Fossil Fuels in Australia
January 8, 2014 07:35 AM - Celsias, Clean Techies

A study by Bloomberg New Energy Finance (BNEF) in Australia has discovered that renewable energy is cheaper to produce than the old conventional fossil fuel sources, and that is without the subsidies. The study shows that electricity can be supplied from a new wind farm at a cost of AUD 80/MWh (USD 83), compared to AUD 143/MWh from a new coal plant or AUD 116/MWh from a new baseload gas plant, including the cost of emissions under the Gillard government’s carbon pricing scheme. However even without a carbon price (the most efficient way to reduce economy-wide emissions) wind energy is 14% cheaper than new coal and 18% cheaper than new gas.

2014 National Defense Authorization Act is huge win for LEED green building system
January 3, 2014 09:15 AM - Stuart Kaplow, courtesy Green Building Law Update, Clean Techies

President Obama signed the National Defense Authorization Act for fiscal 2014 in Honolulu last Thursday and while most observers noted that the bill cracks down on sexual assaults in the military and eases restrictions on transferring detainees from Guantanamo Bay, the bill also is a huge win for the U.S. Green Building Council's LEED green building rating system. By way of background, the Air Force, Army, Marines, Navy and other instruments of the Department of Defense own and operate 299,000 buildings and 211,000 additional structures, making it the largest owner of buildings in North America, but it is also the owner of more green buildings and more LEED certified buildings than anyone else.

COLLEGIATE CORNER: Saving Earth from Space
January 2, 2014 12:41 PM - Destiny Allen; Environment, Economics, Development, Sustainability (EEDS), Class of 2015, The Ohio State University

When we think of the environment, we do not immediately jump to thinking of outer space. The environment usually conjures up images on Earth of breathless beauty, but this does not mean a solution to renewable energy is bound to the limits of our planet.

Ways to recycle a Christmas tree
December 29, 2013 08:39 AM - Beth Buczynski, Care2

For nearly a month (maybe longer if you're one of those day-after-Thanksgiving types), your Christmas tree has formed the centerpiece of holiday celebrations. But now, as the New Year draws near, it's time to think about what to do with it. If, like millions of people, you chose a fresh cut tree, it's important to think long and hard about recycling. After all, a carbon-sucking plant gave its life so that you could honor the pagan tradition of decorating a tree. Just tossing it in the garbage is a depressing waste, especially when there are so many other creative options. Below is a list of the most creative ideas we've ever seen for repurposing Christmas trees. Although most of us will undoubtedly choose number one (the easiest option), the others will warm your heart as well.
