Filipino delegate: no denying climate change now
November 13, 2013 09:24 AM - Jeremy Hance, MONGABAY.COM
Monday, the Filipino delegate to the ongoing climate summit, Naderev 'Yeb' Saño, dared climate change deniers to take a hard look at what's happening not just in the Philippines, but the whole world. Over the weekend, the Philippines was hit by what may have been the largest typhoon to ever make landfall: Typhoon Haiyan. Reports are still coming in days later; death tolls were initially estimated to be over 10,000 with whole cities simply swept away, but more recent reports are placing the death toll lower but still substantial.
Tiny islands with big climate change problems
November 12, 2013 02:25 PM - Jan Piotrowski, SciDevNet
Tiny island states that speck the vast swathe of the Pacific Ocean have a far greater importance in understanding global climate change than their tiny populations would suggest. This was the message given to delegates during a side event of the UN Framework Convention on Climate Change's 19th annual meeting in Warsaw today.
LEED certification tax credit eligibility deadline fast approaching
November 11, 2013 02:22 PM - Guest contributed , Clean Techies
With construction projects facing deadlines to be eligible for tax credits, drop dead dates to meet contractual obligations and otherwise needing to obtain LEED certification by December 31st, submission deadlines to the Green Building Certification Institute are fast approaching. Appreciate that a couple of weeks ago (i.e., the week that ended November 2nd) 48 projects comprising 8,833,676 square feet achieved LEED certification in the U.S. (not including Homes or the several 'confidential' projects that were certified).
Transforming the Solar Discussion
November 11, 2013 01:08 PM - Robin Blackstone, ENN
The sun’s energy has been a central component of the renewable energy cache, including several harnessing technologies such as solar heating, photovoltaics, thermal, architecture and artificial photosynthesis. Researchers at the University of Cincinnati are bringing forth a new method of solar capture and storage called SmartLight that includes the use of electrofluidic cells in concert with embedded photovoltaics placed at the top of a building’s windows. These solar capture elements are then used to project light into the building through a continuous grid-strip of electrofluidic cells. Lead researcher, Jason Heikenfeld envisions these cell channels running across the top of a room and through room adjoining transom windows for distribution as needed within any of the office building’s rooms regardless of its position within the building.
Port development threatens Jamaican Iguana comeback
November 9, 2013 07:00 AM - Adam Andras, MONGABAY.COM
The story of the Jamaican iguana (Cyclura collie) is one of adversity and resurgence. Once believed extinct, the species has made a remarkable comeback over the last two decades. However, according to concerned scientists, a new plan to build a massive port in the iguana's habitat could push the species back to the edge of extinction.
Deep sea Drilling in New Zealand
November 6, 2013 01:51 PM - Rachel Shaw, The Ecologist
Deep sea drilling will soon commence in the rough waters off the New Zealand coast. This could mark the beginning of an oil rush in which democratic process, public concern, environmental protection and safety considerations are all swept aside. The Exclusive Economic Zone (EEZ) around New Zealand is fifteen times larger than the country's land area - it extends from the sub-tropical to the sub-Antarctic. Like the Arctic, New Zealand's EEZ supports a multitude of species which travel from far-flung areas of the globe to reach these rich waters. Like the Arctic, New Zealand's EEZ is fast becoming an oil exploration frontier.
Hotel Marketing Strategy: To Green or Not to Go Green
November 6, 2013 12:39 PM - Robin Blackstone, ENN
Over the last decade hotels and other businesses have increasingly adopted more and more green strategies as part of their daily operations. These strategies have transcended to marketing declarations of eco-certification that are then toted on hotel websites and other marketing materials for the consumer’s consideration when making their purchase decision. Researchers from Cornell’s School of Hotel Administration have studied the benefits of this certification to determine its effectiveness for capturing business. But does this matter to the consumer?
2013 PCB dredging on the Hudson
November 5, 2013 02:50 PM - Editor, ENN
The U.S. Environmental Protection Agency today announced that more than 612,000 cubic yards of river bottom sediment contaminated with PCBs were removed from the upper Hudson River during 2013, exceeding the annual goal of 350,000 cubic yards for this historic dredging project. This is similar to the amount dredged in 2012 when more than 650,000 cubic yards were removed. The Superfund cleanup required by the EPA calls for the dredging of approximately 2.65 million cubic yards of PCB-contaminated sediment from a 40-mile stretch of the upper Hudson River between Fort Edward and Troy, New York. The project began in 2009 and is about 73% complete, putting the dredging on track to be finished in two years. To date, about 1.9 million of the 2.65 million cubic yards million have been removed. Filling of previously dredged areas with clean sand and gravel will continue over the next several weeks, weather permitting. About 280 local area contractors, subcontractors, vendors and suppliers have provided goods or services related to Hudson River dredging.
Do dams bring more harm or more good?
November 4, 2013 09:01 AM - Editor, ENN
As China forges ahead with its goal to generate 120,000 megawatts of renewable energy by 2020, they are damming more and more rivers. According to China, this is a safe strategy that will curb pollution, control floods, and minimize climate change. Conservationists and scientists across the globe however, disagree.
Wind Turbine Arrangement: Staggering Results
October 31, 2013 03:48 PM - Robin Blackstone, ENN
Location and organization apparently matters after all! Or at least that is what Cristina Archer, Assistant Professor at the University of Delaware has discovered with regard to wind turbine efficiency. Dr. Archer headed up a team of researchers from UD's College of Earth, Ocean and Environment to conduct studies on the effects of various wind turbine organizational placement patterns. Using a wind farm near Sweden for the basis of their study, they compared existing tightly paced, grid-like layouts to six alternate configurations. They tried multiple spacing distances in various styles of rows: straight arrays, linear but equal offsets and a staggered theatre style where any turbine in front does not obstruct the view from any one behind.
