Greener chemical cleanups
February 26, 2014 12:14 PM - Marianne English Spoon, University of Wisconsin
Cleaning up oil spills and metal contaminants in a low-impact, sustainable and inexpensive manner remains a challenge for companies and governments globally. But a group of researchers at UW—Madison is examining alternative materials that can be modified to absorb oil and chemicals. If further developed, the technology may offer a cheaper and "greener" method to absorb oil and heavy metals from water and other surfaces.
Passing the baton in oil spill research on the Gulf Coast
February 26, 2014 09:30 AM - Woods Hole Oceanographic Institution Media Relations Office
As part of on-going research nearly four years after the Deepwater Horizon oil spill, scientists from the Woods Hole Oceanographic Institution (WHOI) will team up with a group of high school students in Florida to collect remnants of oil from Gulf Coast beaches this week. Marine chemist Chris Reddy studies how the many compounds that compose petroleum hydrocarbon, or oil, behave and change over time after an oil spill. He and his researchers have collected and analyzed about 1,000 oil samples from the Gulf Coast since the Deepwater Horizon oil spill.
Free mobile green apps
February 25, 2014 10:25 AM - Robin Blackstone, ENN
Incorporating sound environmental decisions in our daily lives has been made easier with the availability of several green apps for the mobile device. Below is a list of five useful environmental apps that are free and feature discussions and motivators for carbon footprint identification and reduction, climate change, global forest cover, product scoring based upon environmental impact, and environmental actions all aimed at making better choices for sustainable living.
COLLEGIATE CORNER: Fossil Fuels vs. Renewable Resources
February 24, 2014 01:07 PM - Flavio Avalos, Class of 2015, Wakefield High School, Arlington, VA
Fossil fuels have been the main source of the energy all over the world. They increase the amount of CO2 emissions, and the emission of CO2 is a great cause of global warming in the atmosphere, destroying the atmospheric layers. What can we do to lower the demand of fossil fuels and become more eco friendly with renewable energy resources? The percent of US transportation sector consumption is 95.4% fossil fuels (Article 3), and this shows the reliance of the US on fossil fuels. As the Institute for Energy states, "Fossil Fuels make modern life possible" and that the only reason that our modern society works and the privileges we get are all due to the fact of fossil fuels (Article 3). Need I remind you: fossil fuels are limited and could go out?
Report Finds 42,000 Turtles Harvested Each Year by Legal Fisheries
February 21, 2014 10:05 AM - Allison Winter, ENN
Conservation awareness for sea turtles has made great progress recently, however the species are still under threat. Not only are hundreds of thousands of sea turtles killed each year from bycatch and illegal fishing but, in many coastal communities, sea turtles are considered a food source. Despite having spiritual or mythological importance, human populations consume both turtle eggs and meat. A new study conducted by Blue Ventures Conservation and staff at the University of Exeter's Centre for Ecology and Conservation has found that 42 countries or territories around the world still permit the harvest of marine turtles — and estimates that more than 42,000 turtles are caught each year by these fisheries.
Wind farms have longer operational life than previously thought
February 20, 2014 08:03 AM - ClickGreen Staff, ClickGreen
New wind farms have a longer economic lifespan than gas-turbine power stations, according to fresh research that also dismisses claims that ageing wind installations are a bad investment. The UK has a target of generating 15 per cent of the nation's energy from renewable resources such as wind farms by 2020. There are currently 4,246 individual wind turbines in the UK across 531 wind farms, generating 7.5 per cent of the nation's electricity.
Trouble for Tea
February 19, 2014 08:58 AM - Ann-Marie Brouder, The Ecologist
Britain's favorite tipple faces big challenges over coming decades, writes Ann-Marie Brouder. A new report sets out the challenges and proposes sustainable solutions to keep the 'cup that cheers' on the nation's tables. Tea is big business: three billion cups of it are consumed every day, 4.8 million tonnes are produced annually, and in Britain two in three people drink it daily. And tea is much more than just a business - many people and cultures have a deep emotional attachment to the 'cup that cheers', and would be horrified at the idea that there was any threat to their beloved beverage.
Air travel gone batty!
February 18, 2014 01:37 PM - Jason Socrates Bardi, American Institute of Physics
By exploring how creatures in nature are able to fly by flapping their wings, Virginia Tech researchers hope to apply that knowledge toward designing small flying vehicles known as "micro air vehicles" with flapping wings. More than 1,000 species of bats have hand membrane wings, meaning that their fingers are essentially "webbed" and connected by a flexible membrane. But understanding how bats use their wings to manipulate the air around them is extremely challenging -- primarily because both experimental measurements on live creatures and the related computer analysis are quite complex.
Fracking residual waters
February 18, 2014 09:40 AM - Robin Blackstone, ENN
As fracking amongst Marcellus Shale in the northeastern part of the United States increases so does the concern over its process. Fracking is done utilizing a hydraulic fracturing process, which pumps a high-pressure mixture of water, chemicals and sand deep into the sedimentary formations to extract naturally occurring gas. The resultant wastewater is then stored in large impoundment ponds and closed container tanks until it can be piped to wastewater treatment plants. Once cleaned it is discharged into local streams or trucked to Ohio to be pumped deep down into another injection well or into another fracking operation.
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.
