Could Lithium-air batteries make oil obsolete?
November 24, 2015 06:47 AM - Editor, The Ecologist
Sooner than it takes to build a nuclear power station, lithium-air batteries could be helping wind and solar to make coal, oil and nuclear obsolete, say Cambridge scientists. Five times lighter and five times cheaper than current lithium batteries, Li-air would open the way to our 100% renewable future.
How to Eat and Stay Healthy this Holiday Season
November 23, 2015 07:23 AM - Patti Verbenas, Rutgers University
When it comes to maintaining healthy lifestyles, people tend to fall off the wagon from Thanksgiving through New Year’s Day. Then, they set “get in shape” and “lose weight” as New Year’s resolutions. That’s not the best idea, says Charlotte Markey, a Rutgers University-Camden psychologist who teaches a course titled “The Psychology of Eating” and studies eating behaviors, body image and weight management. Overeating during the holidays, she notes, is not a matter of if, but when. People need to approach their goals in a smarter way.
Rutgers Today spoke with Markey, the author of Smart People Don’t Diet: How the Latest Science Can Help You Lose Weight Permanently, about a more realistic and sustainable strategy to losing weight and living healthier.
Food industry focuses on sustainable sourcing to mitigate climate change
November 20, 2015 06:59 AM - Sarantis Michalopoulos, EurActiv
Faced with a raw materials scarcity due to climate change, food and drink giants have turned to a sustainable management in order to protect the environment and ensure their future viability. The global population is expected to rise from 7.3 billion today to 9.7 billion in 2050, according to UN projections. As a consequence, according to a survey published in July by FoodDrinkEurope, this will require a 60% increase in food supplies globally, as well as a 30% rise in global demand for water for agriculture.
World's First Solar Road Exceeds Expectations
November 16, 2015 07:21 AM - Matthew Young, Triple Pundit
The first aptly-titled SolaRoad made its debut last November in the Netherlands, not far from Amsterdam. The road itself is a unique foray in pollution-free solar energy. Nearly one year later, the SolaRoad’s designers say the high-tech bike path is performing better than they expected.
In the first six months since it was installed, the SolaRoad has generated over 3,000 kilowatt-hours — or roughly the equivalent required for a single-person household for one calendar year.
America Recycles Day November 15th
November 13, 2015 10:13 AM - JustMeans, Justmeans
Thousands of creative recycling events are being planned for America Recycles Day (ARD), a Keep America Beautiful initiative, which takes place on and in the weeks leading up to Nov. 15.
America Recycles Day is the only nationally recognized day dedicated to promoting and celebrating recycling in the United States. In its 18th year, ARD educates people about the importance of recycling to our economy and environmental well-being, and helps to motivate occasional recyclers to become everyday recyclers.
A number of ARD special events are focusing on this year’s theme of “Bathrooms, Bags & Gadgets." They include:
Obama Rejects Keystone XL Pipeline
November 9, 2015 06:41 AM - Center for Biological Diversity
In a crucial victory for the climate, wildlife and the millions who spoke against it, President Obama rejected the Keystone XL project today, saying that building the tar sands oil pipeline is not in the national interest.
Over the past four years, scientists, environmentalists, tribes, farmers, celebrities and business people joined forces to fight the pipeline, with more than 2 million comments submitted to the U.S. State Department, tens of thousands participating in rallies against Keystone in all 50 states, and thousands of citizens arrested in peaceful civil disobedience.
“This is a historic moment, not just for what it means about avoiding the impacts of this disastrous pipeline but for all of those who spoke out for a healthy, livable climate and energy policies that put people and wildlife ahead of pollution and profits,” said Valerie Love with the Center for Biological Diversity. “President Obama did the right thing, but he didn’t do it alone: Millions of Americans made their voices heard on this issue, and will continue pressing Obama and other political leaders to do what’s necessary to avoid climate catastrophe.”
Assessing the health and economic consequences of Dieselgate
October 29, 2015 08:01 AM - MIT News
Volkswagen’s use of software to evade emissions standards in more than 482,000 diesel vehicles sold in the U.S. will directly contribute to 60 premature deaths across the country, a new MIT-led study finds.
In September, the Environmental Protection Agency discovered that the German automaker had developed and installed “defeat devices” (actually software) in light-duty diesel vehicles sold between 2008 and 2015. This software was designed to sense when a car was undergoing an emissions test, and only then engage the vehicle’s full emissions-control system, which would otherwise be disabled under normal driving conditions — a cheat that allows the vehicles to emit 40 times more emissions than permitted by the Clean Air Act.
That amount of excess pollution, multiplied by the number of affected vehicles sold in the U.S. and extrapolated over population distributions and health risk factors across the country, will have significant effects on public health, the study finds.
Why are diesel cars so popular in Europe?
October 27, 2015 08:04 AM - EurActiv
An estimated annual 'tax gap' subsidy of some €16 billion for diesel over petrol has made Europe the world's largest market for diesel cars - but the Volkswagen scandal has put the national tax schemes supporting this industry at risk.
“There is no reason to keep subsidising this sector," Carlos Calvo, policy analyst at Transport & Environment, told EurActiv on Monday (26 October). The efficiency of petrol-fuelled cars has improved significantly in recent years, while the diesel industry has reduced its nitrogen-oxide emissions only very slowly.
Volkswagen begins recalling diesels in Europe
October 19, 2015 06:54 AM - Leon Kaye
The good news for Volkswagen is that it delivered almost 7.5 million vehicles to customers during the first three quarters of 2015. The bad news is that 8.5 million of VW’s cars will most likely be subject to a mandatory recall — and that’s just in Europe.
The fallout from the Volkswagen emissions scandal continues to reverberate, four weeks after revelations about the installation of “defeat device” software in diesel-powered cars slammed the newswires. Now, the world’s largest automaker is facing a global public relations crisis. This includes its home base: 2.8 million of the recalled vehicles were sold in Germany.
Ecotourism can put wild animals at risk
October 9, 2015 01:59 PM - UCLA Newsroom
Ecotourism, in which travelers visit natural environments with an eye toward funding conservation efforts or boosting local economies, has become increasingly popular in recent years. In many cases it involves close observation of or interaction with wildlife, such as when tourists swim with marine animals. Now, life scientists have analyzed more than 100 research studies on how ecotourism affects wild animals and concluded that such trips can be harmful to the animals, whose behaviors may be altered in ways that put them at risk.
