Los Angeles Celebrates Launch of Largest Municipal Solar Program in U.S.
April 29, 2013 08:44 AM - Bonnie Hulkower, Triple Pundit
Los Angeles, a city more often known for its celebrity sightings and Hollywood stars, also shines bright in the solar arena. The City of Angels has dazzled in the last decade with a strong record of sustainability. So much so that on April 19th, local and national government representatives as well as business leaders gathered to celebrate the launch of the city's solar Feed in Tariff (FIT) program (Clean L.A. Solar Program) at the Los Angeles Business Council's (LABC) Sustainability Summit. The program focused on how to harness sustainability programs and regulatory initiatives for job growth.
EV's will help balance the electric grid
April 29, 2013 06:19 AM - EurActiv
A technology developed with the University of Delaware has sold power from electric vehicles to the power grid for the first time, the power company NRG Energy Inc said on Friday (26 April). In a joint statement, the university and NRG said that they began work on the so-called eV2g program in September 2011 to provide a two-way interface between electric vehicles and the power grid, enabling vehicle-owners to sell electricity back to the grid while they are charging their cars. NRG said the project became an official participant in the PJM frequency regulation market on February 27. The system, which is still in development, is not yet commercially-available.
Which emits more CO2, corn fields or home lawns?
April 28, 2013 08:46 AM - ScienceDaily
More carbon dioxide is released from residential lawns than corn fields according to a new study. And much of the difference can likely be attributed to soil temperature. The data, from researchers at Elizabethtown College, suggest that urban heat islands may be working at smaller scales than previously thought. These findings provide a better understanding of the changes that occur when agricultural lands undergo development and urbanization to support growing urban populations.
Women are 'key drivers' in climate change adaptation
April 25, 2013 01:44 PM - Bernard Appiah, SciDevNet
Plans to protect ecosystems and help people adapt to climate change - also known as ecosystem-based adaptation (EBA) - must involve vulnerable groups, including women and communities greatly hit by global warming if they are to succeed, according to scientists who met in Tanzania last month (21-23 March). Scientists and policymakers at the UN-led international workshop on EBA in Dar-es-Salaam, also said that more needed to be done to monitor and evaluate the cost-effectiveness of such adaptation, and to learn from past experiences in order to transfer knowledge into action and policy.
Air pollution linked to life-threatening hardening of the arteries
April 25, 2013 08:47 AM - ClickGreen Staff, ClickGreen
Long-term exposure to air pollution may be linked to heart attacks and strokes by speeding up atherosclerosis, or "hardening of the arteries", according to a University of Michigan public health researcher and colleagues from across the US. Sara Adar, the John Searle Assistant Professor of Epidemiology at the U-M School of Public Health, and Joel Kaufman, professor of environmental and occupational health sciences and medicine at the University of Washington, led the study that found that higher concentrations of fine particulate air pollution (PM2.5) were linked to a faster thickening of the inner two layers of the common carotid artery - an important blood vessel that provides blood to the head, neck and brain.
EV Range Anxiety Cure?
April 24, 2013 06:15 AM - Roger Greenway ENN and Bill DiBenedetto, Triple Pundit
As an electric vehicle fan, I can appreciate the range anxiety concern. I am driving a Chevy Volt which is great since it has a range extending gasoline engine. Since I enjoy driving in in EV mode so much, and that range is only 35 - 40 miles for me, I decided to go all electric and ordered a Tesla Model S. This will be EV all the time, but with no on-board back up generator, will not be usable for really long trips until the charging infrastructure improves a lot. So I am keeping an older internal combustion engine car for use on long trips! ENN Affiliate TriplePundit reports on an approach to ending range anxiety for people who don't want, or can't keep an internal combustion engine back up car around. Fiat and BMW feel your pain and have come up with a solution of sorts that might boost their EV sales: They will give customers free access to conventional gas-powered cars when they need them for long trips. BMW's i3 electric car is entering the U.S. market this year, and will come with a free loaner conventional car for trips that exceed its 80- to 100-mile range. Customers also will have the option of adding a gasoline generator to the i3 for about $4,000, which would double its range. The retail price for the i3 is estimated at $42,000 to $48,000.
Understanding AC Refrigerant Standards
April 23, 2013 09:13 AM - Andrew Burger, Triple Pundit
Back in 1987, alarm about emissions of ozone layer-depleting chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and bromine gases led national governments worldwide to sign the Montreal Protocol on Substances that Deplete the Ozone Layer, a United Nations (UN) environmental agreement in which 197 countries and the European Union (EU) pledged to phase out production and use of CFCs, HCFCs and bromine gases. Though revised, more aggressive reduction targets for new refrigerant standards are being met, subsequent developments — rapid industrialization in large emerging market countries and the growing threats and costs of global warming — have complicated matters further.
UN Urges Member Nations Renew Pledges to Respect Earth
April 23, 2013 06:19 AM - United Nations News Service
Top United Nations officials today urged the 193 Member States to renew their pledges to honour and respect Mother Earth marking the day selected by the world body to promote harmony with nature and sustainable development. Today is a "chance to reaffirm our collective responsibility to promote harmony with nature," Secretary-General Ban Ki-moon told the Interactive Dialogue on Harmony with Nature held to mark International Mother Earth Day. Noting this year's theme, Faces of Climate Change, Mr. Ban urged the UN General Assembly "to confront the hard truth that our planet is under threat."
Earth Day - Hollywood Style
April 22, 2013 03:14 PM - BILL KEITH, The Credits
For years, Hollywood has celebrated Earth Day in order to raise awareness about environmental issues and to strike up a memorable dialogue about sustainable practices. And the film studios’ embrace of Earth Day has only strengthened over time. From PSAs to Paramount’s new micro-turbines, we take a look at the industry’s dedication to spotlighting one of the most important advocacy dates on the calendar. In 1990, the holiday got a pretty big boost from Hollywood when Time Warner called on some of their favorite talent to hammer home proactive things Americans could do to reduce their footprint on the planet. (Our favorites? A pony-tailed Kevin Costner teaching Meryl Streep how to recycle and Neil Patrick Harris as Doogie Howser giving a press conference about the health of his patient, "Mother Earth.") But in 2013, the film business's efforts have far exceeded PSA productions, and the good news is that a lot of progressive practices like electric car fueling stations, composting, a ban on plastic bags in commissaries, and required carbon emission reporting have become all but de rigueur on most major lots. As each of the main studios shoot to achieve "100% sustainable" status in the coming years, the pressure is on to determine creative ways to be the first to get there, and then some. In honor of Earth Day, we take a look at some of the ways Hollywood is committed to 'greening' up their practices:
A new tool against illegal logging: tree DNA technology goes mainstream
April 22, 2013 08:47 AM - Tanya Dimitrova, MONGABAY.COM
The role of tree DNA tracking is increasing in the fight against illegal logging as evidenced by prosecution cases in USA and Germany. Modern DNA technology offers a unique opportunity: you could pinpoint the origin of your table at home and track down if the trees it was made from were illegally obtained. Each wooden piece of furniture comes with a hidden natural barcode that can tell its story from a sapling in a forest all the way to your living room.
