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.
UK Government Panel weighs in on fracking risks
November 3, 2013 09:04 AM - Staff, ClickGreen
Government health chiefs have admitted there is a risk to public health from exposure to emissions from shale gas extraction under the current monitoring framework. And scientists at Public Health England (PHE) admit that in the absence of regulations in the UK, drilling operators could potentially use a "wide range of chemical, many of which are classified as highly toxic and/or carcinogenic". It confirms that the risks from small-scale drilling for exploratory purposes are "clearly different from the risks from commercial scale operations".
Chickens to benefit from surge in biofuels popularity
November 1, 2013 10:10 AM - ClickGreen Staff, ClickGreen
Chickens could be the unexpected beneficiaries of the growing biofuels industry, feeding on proteins retrieved from the fermenters used to brew bioethanol, thanks to research supported by the Engineering and Physical Sciences Research Council (EPSRC). It has long been known that the yeasty broth left over after bioethanol production is nutritious, but it has taken a collaboration between Nottingham Trent University and AB Agri, the agricultural division of Associated British Foods, to prove that Yeast Protein Concentrate (YPC) can be separated from the fibrous cereal matter.
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.
Renewable energy revolution will require better management of metals
October 31, 2013 01:38 PM - Jeremey Hance, MONGABAY.COM
If we are to avoid catastrophic climate change, scientists say global society will need a rapid and aggressive replacement of fossil fuel energy for renewable, such as solar, wind, geo-thermal, and tidal. While experts say a renewable revolution would not only mitigate climate change but also likely invigorate economies and cut life-threatening pollution, such a revolution would not come without challenges.
Mercury Sediment Carried Forth by California Floods
October 29, 2013 01:59 PM - Robin Blackstone, ENN
Mercury contamination in sediment has been a big concern in the Central Valley lowland areas of California. But associate researcher from the University of California, Michael Singer has unearthed new information and considerations utilizing modern topographic datasets and modeling to track mercury-laden sediment. Singer hypothesizes that the progradation process resulting from 10-year flooding events within the valleys below the Sierra Nevada Mountains are the key to understanding and tracking the presence of mercury. Singer has connected the mercury amalgamation process, which was used to extract gold from the mountains during the 19th century with the current high incidence of mercury in regional delta sediment.
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.
Nuclear power gets twice the price of solar!
October 28, 2013 08:31 AM - Oliver Tickell, Ecologist
The UK government's policy to pay for more for nuclear power than for power from solar PV is in direct contradiction of EU rules on state aid. The Hinkley C nuclear power station is to be paid more than twice as much as German solar pv arrays of 10MW or more, energy expert David Toke of Aberdeen University has calculated. And even smaller arrays are being paid considerably less than the price paid to EDF at Hinkley.
Kazakhstan nuclear test site clean up success
October 27, 2013 08:32 AM - Paul Lowe / Panos, SciDevNet
A Soviet-era nuclear test site in Kazakhstan was cleaned up through a collaborative international project that could provide lessons for tackling other dangerous nuclear sites across the globe, a report reveals. The report, entitled 'Plutonium Mountain', documents how international scientific cooperation was important for securing nuclear waste from the site. It was released in August by the Belfer Center for Science and International Affairs at Harvard University, United States. The Semipalatinsk test site, which spans an area about the size of Belgium, lies in a remote part of eastern Kazakhstan. It embodied the post-Cold War risk of 'loose nukes' -- the threat that terrorists or rogue states could obtain nuclear fissile materials — according to the report.
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.
