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.
Sandy’s path of destruction felt in the Caribbean too
October 29, 2013 04:17 PM - Robin Blackstone, ENN
Last year at this time much of the United States eastern seaboard was closely monitoring Super Storm Sandy. Hour by hour people watched with horror as she blew across the Dominican Republic, Haiti, Cuba and the Bahamas ultimately charging up the Atlantic, swinging west to crash into the Mid-Atlantic states at full force. Damage to New York and New Jersey was extensive to be sure, but the larger populations and greater affluence to the north have largely overshadowed recovery of the Caribbean nations.
Africa's biggest wind farm opens
October 28, 2013 09:03 AM - Oliver Tickell, The Ecologist
Africa's biggest wind farm, at Ashegoda in Tigray, Ethiopia, is being inaugurated today after a three year construction period. This marks the completion of the last of three construction phases. The 120 MW wind farm has already injected 90 MWh of electricity into Ethiopia's power grid since commissioning began earlier this year, and is expected to produce a total of 400,000 MWh per year hereafter.
India blocks progress on HFC emissions reductions
October 25, 2013 05:05 PM - Oliver Tickell, The Ecologist
The Indian Government has single-handedly blocked progress on an agreement to reduce emissions of the super-powerful greenhouse gases known as hydrofluorocarbons (HFCs). The G20 - which includes India as the world's tenth largest economy - resolved in September to phase down the consumption and production of HFCs under the Montreal Protocol, the international treaty which has successfully slashed emissions of ozone eating CFCs. But in the 25th meeting of the Montreal Protocol in Bangkok, which ended today, India deliberately blocked detailed discussions of the HFC-reduction proposals.
Wind power could generate 18% of global power by 2050

Wind power could generate up to 18% of the world's electricity by 2050, compared with 2.6% today, according to new IEA research. The Technology Roadmap: Wind Energy — 2013 Edition finds that nearly 300 gigawatts of current wind power worldwide must increase eight- to ten-fold to achieve the roadmap's vision, with the more than USD 78 billion in investment in 2012 progressively reaching USD 150 billion per year.
Air Pollution and Cancer Spikes linked in Alberta
October 23, 2013 11:48 AM - Editor, ENN
Alberta is Canada's industry epicenter and home to more than 40 companies that produce industrial emissions. Recent studies conducted by the University of California and the University of Michigan have indicated higher levels of contaminants which can potentially be linked to spikes in the incidences of cancer in the region.

Dallas has now accepted the first building permit applications under its green building ordinance. Dallas is one of the first major cities in the nation to implement comprehensive mandatory green building standards for both all new residential and commercial construction. By Resolution 08-1070 adopted unanimously on April 9, 2008 Phase 1 of the law was effective in 2009 and Phase 2 (originally to be effective October 1, 2011) was fully implemented October 1, 2013.
Greece Considers Sacrificing Environment to Save Economy

In crisis-hit Greece, government decisions taken in haste and despair to save the country from default, risk having a serious impact on the environment. A new bill seeks to relax restrictions on construction of public and private forestland even for those areas, which are considered protected.
Breaking Urban Ground for Community Gardens
October 15, 2013 05:15 PM - Robin Blackstone, ENN
Community Gardens bring people together, builds relationships, improves quality of life and activates communities through its bounty, exercise, therapy, education, family budget augmentation, social interaction and neighborhood beautification. A community garden can be used for food, ornamental gardening, urban forestry, preservation and management of open space, memorial gardening and any other types of gardening that a community collectively values. But much goes into creating one especially if it's an urban garden.
"Collegiate Corner", COMING SOON!
October 15, 2013 11:12 AM - Robin Blackstone, ENN
ENN is launching a new section called the "Collegiate Corner" for college and university students at ALL levels (undergrad, grad and PhD) to submit original work for publication. We are looking for environmental writing and scientific studies. This is an opportunity for students to become recognized in their field utilizing their own writing and work. Items considered appropriate include research papers, posters, or studies to include any of the following subjects: toxicology, land use, biology, regulatory, social, economic, health, etc. Preferred works include those that are either global in appeal or their lessons can be applied globally.
