Spray-on Solar Panels?
August 4, 2014 03:33 PM - ClickGreen Staff, ClickGreen
A team of scientists at the University of Sheffield are the first to fabricate perovskite solar cells using a spray-painting process — a discovery that could help cut the cost of solar electricity. Experts from the University's Department of Physics and Astronomy and Department of Chemical and Biological Engineering have previously used the spray-painting method to produce solar cells using organic semiconductors - but using perovskite is a major step forward.
Study predicts climate change and pollution will combine to impact food production
August 2, 2014 09:50 AM - EcoRI News staff
Many studies have shown the potential for global climate change to cut food supplies. But these studies have, for the most part, ignored the interactions between increasing temperature and air pollution -- specifically ozone pollution, which is known to damage crops. A new study involving researchers at MIT shows that these interactions can be quite significant, suggesting that policymakers need to take both warming and air pollution into account in addressing food security.
Surf's Up for Clean Technology
August 1, 2014 11:45 AM - Leon Kaye, Triple Pundit
Unless your skin is about a foot thick, swimming and surfing in the Pacific Ocean for hours at a time requires a wetsuit to stay warm and comfortable. That comfort, however, comes at a price as the vast majority of wetsuits are made from petroleum-based neoprene. The material is durable and does the job, but its manufacture is a carbon-intensive and toxic process. Now Patagonia is aggressively promoting its plant-based wetsuit technology with the goal to have it become a game-changer in the surf industry.
Underestimating the Impacts of Old-Growth Logging
August 1, 2014 09:28 AM - Rhett A. Butler, MONGABAY.COM
Ecologists may be underestimating the impact of logging in old-growth tropical forests by failing to account for subtleties in how different animal groups respond to the intensity of timber extraction, argues a paper published today in the journal Current Biology. The study, led by Zuzana Burivalova of ETH Zurich, is based on a meta-analysis of 48 studies that evaluated the impact of selective logging on mammals, birds, amphibians, and invertebrates in tropical forests. Burivalova, together with co-authors Cagan Sekercioglu and Lian Pin Koh, found that biodiversity is inversely proportional to logging intensity.
Drilling in the Dark
August 1, 2014 08:54 AM - University of Wisconsin-Madison
As production of shale gas soars, the industry's effects on nature and wildlife remain largely unexplored, according to a study by a group of conservation biologists published in Frontiers in Ecology and the Environment on August 1. The report emphasizes the need to determine the environmental impact of chemical contamination from spills, well-casing failure, and other accidents. "We know very little about how shale gas production is affecting plants and wildlife," says author Sara Souther, a conservation fellow in the Department of Botany at the University of Wisconsin-Madison. "And in particular, there is a lack of accessible and reliable information on spills, wastewater disposal and the chemistry of fracturing fluids. Of the 24 U.S. states with active shale gas reservoirs, only five maintain public records of spills and accidents." The 800 percent increase in U.S. shale gas production between 2007 and 2012 is largely due to the use of hydraulic fracturing. Also called fracking, the process uses high-pressure injection of water, laden with sand and a variety of chemicals, to open cracks in the gas reservoir so natural gas can flow to the well.
Importance of Air Quality and Employee Productivity
July 30, 2014 09:19 PM - RP Siegel, Triple Pundit
A number of credible studies have shown that indoor air quality can have a significant effect on employee productivity. And we're not just talking about air that's so bad that you can't see or breathe. Generally speaking, OSHA takes cares of those (though I could tell you a story about an agricultural processing job I once worked in Arkansas). What we're talking about here is much more subtle than that.
Green Turtle success story

More than 70 years after major turtle nesting beaches became protected on the remote UK overseas territory of Ascension Island researchers are now reporting a boom in population numbers. Scientists from the University of Exeter and Ascension Island Government Conservation Department report that the number of green turtles nesting at the remote South Atlantic outpost has increased by more than 500 per cent since records began in the 1970s.
General Motors, OnStar, EV's and the Smart Grid
July 29, 2014 01:09 PM - Editor, Justmeans
General Motors is bringing its OnStar-enabled Smart Grid solutions, to one of the largest electric vehicle collaborations to take place within the industry. Eight global automakers, including GM, and 15 electric utilities are working with the Electric Power Research Institute to develop and implement a standardized Smart Grid integration platform. "One thing that’s missing from most Smart Grid programs is a sense of collaboration," said Tim Nixon, chief technology officer, Global Connected Consumer, GM. "Companies will showcase a meaningful solution, but without widespread acceptance in the industry, its usability is limited. That's what makes this partnership unique."
Coffee Rust in Guatemala
July 28, 2014 07:32 AM - Carrie Khan, NPR
Outside the northern Guatemalan town of Olopa, near the Honduran border, farmer Edwin Fernando Diaz Viera stands in the middle of his tiny coffee field. He says it was his lifelong dream to own a farm here. The area is renowned for producing some of the world's richest Arabica, the smooth-tasting beans beloved by specialty coffee brewers. "My farm was beautiful, it was big," he says. But then, a plant fungus called coffee rust, or roya in Spanish, hit his crop. "Coffee rust appeared and wiped out everything," he says.
How to encourage recycling and feed stray animals at the same time!
July 27, 2014 08:28 AM - Kevin Mathews, Care2
Istanbul, Turkey recently unveiled awesome new machines that help both the environment and needy animals. Each time a person recycles a plastic bottle in the designated receptacle, pet food is ejected into a bowl at the bottom so hungry stray animals have something to eat. So far, the machines have been a hit with residents. People who would normally toss bottles in a trash can might wait to carry the plastic a bit longer to dispose of it in the recycling bin now that they know they can assist animals. It’s a win-win scenario that doubles Turkish people's incentive to do the right thing.
