The $40 Billion in US Buildings
April 30, 2013 04:31 PM - Elisa Wood, Clean Techies
A pretty big wad of money — $40 billion — is hiding somewhere inside the lights, AC, thermostats, furnaces and fans of our offices, stores, hospitals and schools. That's the amount of money the federal government estimates we can save annually by reducing energy use in commercial buildings 20 percent by 2020. To achieve the goal, the Obama administration in 2011 initiated the Better Buildings Challenge, a way to encourage investment, share information and create demonstration projects that save energy.
Extended Range Electric & Hybrid Cars that Reduce Environmental Impacts
April 30, 2013 06:10 AM - Maria Ortega, Global Warming is Real
According to National Geographic, more than half the air pollution in the United States is caused by mobile devices, primarily by automobiles. These greenhouse gases that vehicles emit, such as carbon dioxide, are wreaking havoc on the ozone layer as well as polluting the soil and surface water in many cases. Bottom line— while cars are an everyday necessity and convenience, they're not doing the environment any favors. That's part of the reason why the federal government is offering tax incentives to those who purchase hybrid or electric vehicles, as well as challenging automakers to develop vehicles by 2025 that are able to achieve 55 mpg on the highway. It’s a bold goal but, as you can see from how much cars are responsible for pollution, it’s a necessary one that’s becoming more important.
Supermarket delivery services are greener than driving to shop
April 29, 2013 01:05 PM - ClickGreen Staff, ClickGreen
A new academic research study has revealed it is better for the environment to order the weekly supermarket shop to be delivered to your doorstep with carbon emission savings of up to 75%. University of Washington engineers have found that using a supermarket delivery service can cut carbon dioxide emissions by at least half when compared with individual household trips to the store. Trucks filled to capacity that deliver to customers clustered in neighborhoods produced the most savings in carbon dioxide emissions.
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.
