One-in-five products not complying with energy saving claims
February 18, 2014 08:08 AM - ClickGreen Staff, ClickGreen

One in five energy-using products across Europe do not match their energy efficiency claims, according to the Energy Saving Trust. This follows findings from European Commission-funded research which revealed that up to 20 per cent are non-compliant with energy efficiency standards, such as energy labeling. According to estimates, this is leading to around ten per cent of the potential energy savings stated being lost by millions of products across Europe, including ovens, fridges, washing machines, dishwashers, televisions and computers.

The first big bite!
February 7, 2014 11:43 AM - Gareth Trickey, University of Toronto

The first top predators to walk on land were not afraid to bite off more than they could chew, a University of Toronto, Mississauga study has found. Graduate student and lead author Kirstin Brink and U of T Biology Professor Robert Reisz suggest that Dimetrodon, a carnivore that walked on land between 298 million and 272 million years ago, was the first terrestrial vertebrate to develop serrated ziphodont teeth. According to the study published in Nature Communications, ziphodont teeth, with their serrated edges, produced a more-efficient bite and would have allowed Dimetrodon to eat prey much larger than itself. While most meat-eating dinosaurs possessed ziphodont teeth, fossil evidence suggests serrated teeth first evolved in Dimetrodon some 40 million years earlier than theropod dinosaurs.

Building Green
February 3, 2014 12:38 PM - ClickGreen Staff, ClickGreen

In a world which faces increasing pressure to reduce carbon emissions, the construction industry must confront demand to adopt modern methods of building which causes less damage to the environment. As a result, there are increasing numbers of alternative materials and methods available, a selection of which are included in this post. While these methods are by no means the only ones available within the industry, the selected materials and methods include: -Metallic paint -Chemical containment -Spray-on insulation -Concrete alternatives -Green roofs Each method boasts the more efficient properties in terms of reducing environmental damage, with the least change to standard methods.

Why can't you walk to the big game?

Super Bowl XLVIII, featuring my archenemies the Seattle Seahawks against the Denver Broncos, is about to go down. Millions of fans will be gathering around TV screens across the country to watch, but of course the best experience of all is available to those who get to see the magic in person at MetLife Stadium. Better yet, organizers are touting this as the "greenest Super Bowl ever," with initiatives like composting, low water landscaping, Energy Star Certified equipment, donation of leftover food, a massive solar panel installation, and the use of recycled steel in construction. In other words, you'd think these guys are pretty serious not just about sports, but also the environment, with all this hard work to make the match as eco-friendly as possible. We're seeing the same kinds of initiatives in Sochi for the Winter Olympics, as well as Rio, indicating that in the sports world, green is in. Which is exciting news for those of us who like the Earth and think it should stick around in habitable form a little longer.

Solar Energy is cash and sunshine in your pocket
January 30, 2014 09:48 AM - Robin Blackstone, ENN

Is there money to be made on your roof? With the never-ending availability of sunshine and the evolution of solar technology many are recognizing the benefits of solar. The decision making process though is not for the faint of heart. Recognizing the difficulty in breaking through the process a company called Generaytor out of Tel Aviv has developed a free web-based app to show how much money can be saved and made with rooftop solar panels.

Slowing down the floodwaters
January 29, 2014 10:41 AM - Robin Blackstone, ENN

Putting something called "Natural Engineering" to work in a five-year research project, Newcastle University in cooperation with the Environment Agency are discovering the benefits utilizing the land's natural defenses to slow river flow downstream and prevent flooding. Slowing down water in anticipation of flooding events is being tested all over the world. Strategies include the use of retention basins; wetlands development; levee systems and floodwalls but Newcastle University researchers directed by Dr. Mark Wilkinson are employing additional water retention strategies further up in the catchment system. The Belford Burn is a small catchment system located in Northumberland, a community just south of the Scottish border.

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.
