E-Waste problem not going away
July 9, 2015 06:08 AM - ClickGreen staff, ClickGreen
While electrical and electronic equipment have never been more efficient, economical or in demand, consumers' desire to own the best and the latest is contributing to an environmental issue of increasing seriousness and concern, according to a new report.
"E-waste is one of the fastest growing waste streams in developing, emerging and developed regions and it covers all electrical and electronic equipment and parts discarded by consumers," says Dr Sunil Herat, Associate Editor of the journal Waste Management & Research and a Senior Lecturer in the School of Engineering at Griffith University in Queensland, Australia.
Advertising coming to EV charging stations?
July 3, 2015 05:04 AM - BOB SHETH, Electric Forum
While many electric vehicle owners will find it irritating and annoying to be hit with adverts when charging their vehicles, is this a sign of the times? The fact that many larger companies are willing and prepared to pay for advertising space on “free” charging devices seems to indicate that the marketing industry believes the sector is here to stay. So, will advertising be a help or a hindrance to the industry going forward?
Until the electric vehicle industry cracks the “mass market” it is vital that the cost of services and products is kept as low as possible. There will come a point when costs will have to rise, services will be chargeable and the whole dynamic will be very different than what we see today but, in the meantime, is advertising on “free” charging stations really a hindrance?
Can pollution be good for trees?
June 30, 2015 07:46 AM - Society for Experimental Biology via EurekAlert!
Trees that can tolerate soil pollution are also better at defending themselves against pests and pathogens. "It looks like the very act of tolerating chemical pollution may give trees an advantage from biological invasion", says Dr Frederic E. Pitre of the University of Montreal and one of the researchers behind the discovery.
Study examines the role of naturally occurring halogens in atmospheric deposition
June 30, 2015 06:11 AM - Cooperative Institute for Research in Environmental Sciences (CIRES) and the University of Colorado Boulder
It’s been difficult to explain patterns of toxic mercury in some parts of the world, such as why there’s so much of the toxin deposited into ecosystems from the air in the southeastern United States, even upwind of usual sources.
A new analysis led by researchers at the University of Colorado Boulder shows that one key to understanding mercury’s strange behavior may be the unexpected reactivity of naturally occurring halogen compounds from the ocean.
Study examines overall carbon cost of fuel from Canadian oil sands
June 28, 2015 06:34 AM - UC Davis via the ECOreport, ECOreport
Gasoline and diesel fuel extracted and refined from Canadian oil sands will release about 20 percent more carbon into the atmosphere over the oil’s lifetime than fuel from conventional crude sources in the Unied States, according to a study by the U.S. Department of Energy’s Argonne National Laboratory; the University of California, Davis; and Stanford University.
The researchers used a life-cycle, or “well-to-wheels,” approach, gathering publicly available data on 27 large Canadian oil sands production facilities. The study, published in the journal Environmental Science and Technology, found the additional carbon impact of Canadian oil sands was largely related to the energy required for extraction and refining.
Fracking helping utilities reduce reliance on coal
June 23, 2015 07:15 AM - MARIE CUSICK, NPR
When you flip on a light switch, odds are, you're burning coal. But as the fracking boom continues to unleash huge quantities of natural gas, the nation's electric grid is changing. Power plants are increasingly turning to this low-cost, cleaner-burning fossil fuel.
Bill Pentak stands in the middle of a construction site, looking up at his company's latest project towering overhead — a new natural gas power plant.
"This plant was sited precisely where it is because of its access to the abundant, high-quality natural gas that's found a mile to two miles beneath our feet," he says.
A look at N2O: Nitrous oxide emissions may be higher than previously thought
June 22, 2015 05:01 PM - Helmholtz Centre for Ocean Research Kiel
In addition to carbon dioxide there are plenty of other greenhouse gases. Nitrous oxide is one of them. However, a global assessment of emissions from the oceans is difficult because the measurement methods used so far have only allowed rough estimates. Using a new technology for continuous measurements, researchers of the GEOMAR Helmholtz Centre for Ocean Research Kiel and the Christian-Albrechts-Universität zu Kiel have now discovered that nitrous oxide emissions from the Southeast Pacific are much higher than previously thought. They publish their data in the international journal Nature Gesoscience.
Why are some states reducing EV incentives?
June 7, 2015 07:33 AM - BOB SHETH, Electric Forum, Electric Forum
First of all we have to say that the vast majority of US state authorities are continuing with their current electric vehicle financial incentives, with many actually increasing the amount of funds available, but some states are struggling. Connecticut, Georgia, and Illinois are just three states in the US where electric vehicle financial incentives are being tapered down. Whether or not they are reintroduced in the future remains to be seen but budgets need to be balanced.
Is this a reflection of the technology?
It would be easy to say that we are yet again looking at a false dawn for the electric vehicle sector but this would be wrong. There has been enormous government and corporate investment in the industry and it is inconceivable to even suggest it will fade away into the background as it has done before. The simple fact is that many states across the US, and governments around the world, are struggling to balance their books during the current tight economic environment and schemes such as financial incentives to switch to electric vehicles are feeling the brunt.
Lower Ozone levels in Houston linked to climate change
May 17, 2015 07:48 AM - Universtiy of Houston via ScienceDaily
Researchers at the University of Houston have determined that climate change -- in the form of a stronger sea breeze, the result of warmer soil temperatures -- contributed to the drop in high-ozone days in the Houston area.
Robert Talbot, professor of atmospheric chemistry, said that also should be true for coastal regions globally.
The researchers describe their findings in a paper published this week in the journal Atmosphere. In addition to Talbot, they include first author Lei Liu, a doctoral student, and post-doctoral fellow Xin Lan.
Five Years and Counting: Gulf Wildlife in the Aftermath of the Deepwater Horizon Disaster
April 17, 2015 09:37 AM - National Wildlife Federation
Five years after the Deepwater Horizon rig exploded, sending oil into the Gulf of Mexico for 87 days, wildlife are still struggling. The Gulf, with its deep waters, sandy beaches, lush wetlands and coral reefs, is a vast system that supports more than 15,000 species of wildlife – fish, birds, marine mammals and many, many others.
A new report from the National Wildlife Federation looks at how 20 types of wildlife that depend on a healthy Gulf are faring in the wake of the BP oil spill. The full extent of the spill’s impacts may take years or even decades to unfold, but Five Years & Counting: Gulf Wildlife in the Aftermath of the Deepwater Horizon Disaster examines what the science tells us so far.
