Climate Change: We have met the enemy and they are us
April 14, 2014 09:35 AM - ENN Editor
According to McGill University physics professor Shaun Lovejoy, we have no one to blame but ourselves for global warming in the industrial era. Lovejoy and his research team have just completed an analysis of temperature data covering more than 500 years. This study all but rules out the possibility that global warming is just a natural fluctuation in the earth's climate.
Largest Cleanup in EPA History Proposed
April 14, 2014 08:14 AM - ENN Staff
In an historic action that will protect people's health and the environment, and benefit riverfront communities, the U.S. Environmental Protection Agency proposed a plan to remove 4.3 million cubic yards of highly contaminated sediment from the lower eight miles of the Passaic River in New Jersey. The sediment in the Passaic River is severely contaminated with dioxin, polychlorinated biphenyls (PCBs), heavy metals, pesticides and other contaminants from more than a century of industrial activity. Ninety percent of the volume of contaminated sediments in the lower Passaic are in the lower eight miles of the river.
US EPA finds the most energy efficient buildings in top 10 cities
April 11, 2014 08:52 AM - US EPA Energy Star
Yesterday the U.S. Environmental Protection Agency (EPA) released its sixth annual list of the 25 U.S. metropolitan areas with the most ENERGY STAR certified buildings in 2013. The list demonstrates economic and environmental benefits achieved by facility owners and managers in America’s leading cities when they apply a proven approach to energy efficiency to their buildings.
2014 ten most endangered rivers
April 10, 2014 12:10 PM - ENN staff
American Rivers yesterday announced its annual list of America's Most Endangered Rivers®, naming California's San Joaquin River the Most Endangered River in the country. Outdated water management and excessive diversions, compounded by the current drought, have put the San Joaquin River at a breaking point.
Coordinated chemistry yields green solutions for more efficient gas storage
April 10, 2014 10:20 AM - ENN Editor
Metal Organic Frameworks (commonly called MOFs) are intricate crystal structures that can store or separate individual elements in a highly efficient manner. MOFs are materials made by linking inorganic and organic units together with strong bonds formed through coordination chemistry. MOFs are not only leading the way in providing clean technology solutions, but are actively being explored by the energy, transportation, and pharmaceutical industries to deliver new applications (for energy storage).
REI Commits to Solar Energy to Reduce Climate Impact
April 10, 2014 08:09 AM - Gina-Marie Cheeseman, Triple Pundit
REI, the $2 billion national outdoor retailer, is committed to renewable energy. The company has 26 locations with solar power systems in eight states (Arizona, California, Colorado, Maryland, Massachusetts, New Jersey, Pennsylvania and Georgia).
LED Bulb Challenge ending soon!
April 9, 2014 01:34 PM - ENN Staff
The most inefficient light bulbs may now be off the market, in response to new federal standards, but nearly 70% of light bulb sockets in the U.S. still contain an inefficient bulb. Retailers across the country are stepping up to help change that, as part of the Energy Star LED Bulb Challenge.
At more than 23,000 feet, why don't bar-headed geese get hypoxic?
April 9, 2014 10:04 AM - ENN Staff
The bar-headed goose migratory path takes it over the Himalayan Mountains each year between China and Mongolia to their Indian breeding grounds. This flight path puts them at 23,917 feet above sea level. University of Exeter led study followed these birds to gain insight into their ability to survive these extreme altitudes in hopes that their findings might have future implications for low oxygen medical conditions in humans.
World's first Water Stewardship Standard is released
April 9, 2014 08:07 AM - ClickGreen Staff, ClickGreen
The first international Water Stewardship Standard, a global framework to promote sustainable freshwater use, has been released by the Alliance for Water Stewardship (AWS). The Standard defines globally applicable, consistent criteria for sustainable management and use of the world's limited freshwater resources. "We are excited to see global leaders join us on the journey towards sustainable and equitable water use," said Michael Spencer, Chair of AWS's board and representative of Water Stewardship Australia.
High Tech Trees!
April 8, 2014 01:20 PM - ENN Staff
Scientists at Oregon State University have found a way to convert tree cellulose into high-tech energy storage devices. Because cellulose is a key component of trees and the most abundant organic polymer on earth this discovery will have a profound impact in industry. Scientists were able to heat the tree cellulose in a furnace in the presence of ammonia to create the building block for supercapacitors for use in industrial electronic applications. Supercapacitors are extraordinarily, high-power energy devices for which production has been held back by cost and difficulty in producing high-quality carbon electrodes.
