MIT finds switching to higher octane fuel would reduce carbon emissions
October 28, 2014 07:15 AM - MIT News
If the majority of light-duty vehicles in the United States ran on higher-octane gasoline, the automotive industry as a whole would reduce its carbon dioxide emissions by 35 million tons per year, saving up to $6 billion in fuel costs, according to a new analysis by MIT researchers.
In a study published in the journal Environmental Science & Technology, the team considered a scenario in which fuel is manufactured under a redefined octane rating — the measure of a gasoline’s ability to resist engine knocking during combustion.
Can the corridors under high-tension lines be important opportunities for conservation?
October 17, 2014 08:06 AM - richard conniff, Yale Environment360
Often mowed and doused with herbicides, power transmission lines have long been a bane for environmentalists. But that’s changing, as some utilities are starting to manage these areas as potentially valuable corridors for threatened wildlife. Nobody loves electrical power transmission lines. They typically bulldoze across the countryside like a clearcut, 150 feet wide and scores or hundreds integrated vegetation management in right-of-way scores or hundreds of miles long, in a straight line that defies everything we know about nature. They’re commonly criticized for fragmenting forests and other natural habitats and for causing collisions and electrocutions for some birds. Power lines also have raised the specter, in the minds of anxious neighbors, of illnesses induced by electromagnetic fields. So it's a little startling to hear wildlife biologists proposing that properly managed transmission lines, and even natural gas and oil pipeline rights-of-way, could be the last best hope for many birds, pollinators, and other species that are otherwise dramatically declining.
Which Form of Energy is the Cheapest?
October 16, 2014 10:47 PM - Kevin Mathews, Care2
Which kind of power is the cheapest? Listen to energy companies, and they'll insist that traditional forms like gas and coal are the way to go. Of course, they have money invested in keeping the existing systems in business. That's why the European Union commissioned an independent analysis to study the topic. According to the report, wind energy is the most cost-efficient way to supply power. When proponents of non-renewable energy point to costs, they intentionally overlook the overall economic impact that polluting causes. Once experts start to calculate the costs associated with public health and climate change that coincide with burning coal and gas, the true cost is far higher than initially reported. It's both irresponsible and shortsighted to ignore these environmental and health consequences from the equation.
Abundant natural gas will not slow climate change according to new study
October 16, 2014 06:22 AM - Pacific Northwest National Laboratory
A new analysis of global energy use, economics and the climate shows that without new climate policies, expanding the current bounty of inexpensive natural gas alone would not slow the growth of global greenhouse gas emissions worldwide over the long term, according to a study appearing today in Nature Advanced Online Publication. Because natural gas emits half the carbon dioxide of coal, many people hoped the recent natural gas boom could help slow climate change — and according to government analyses, natural gas did contribute partially to a decline in U.S. carbon dioxide emissions between 2007 and 2012.
NASA maps methane emissions
October 12, 2014 08:36 AM - University of Michigan via EurekAlert
An unexpectedly high amount of the climate-changing gas methane, the main component of natural gas, is escaping from the Four Corners region in the U.S. Southwest, according to a new study by the University of Michigan and NASA. The researchers mapped satellite data to uncover the nation's largest methane signal seen from space. They measured levels of the gas emitted from all sources, and found more than half a teragram per year coming from the area where Arizona, New Mexico, Colorado and Utah meet. That's about as much methane as the entire coal, oil, and gas industries of the United Kingdom give off each year.
Poland will buy in to climate change plan IF it gets aid
October 10, 2014 06:27 AM - EurActiv
Poland says it will need cash and help in curbing its emissions if it is to sign up for a new decade of EU green energy policy at talks this month, according to a document seen by Reuters. The document shows the 28 EU member states are broadly ready to agree a new set of 2030 goals to follow on from 2020 energy and environment policy, although Europe's biggest power Germany says it will not agree a deal "at any price".
Elephants worth more alive, than when they are poached for ivory
October 9, 2014 08:54 AM - Morgan Erickson-Davis, MONGABAY.COM
Elephants are worth 76 times more when they’re alive than dead, according to a new analysis released this past weekend. The report follows on the heels of findings by WWF that the world has lost 50 percent of its wildlife over the past 40 years, with more than half of African elephants killed for ivory in just one decade. The analysis, conducted through the David Sheldrick Wildlife Trust's iworry campaign, compared the value of elephants to local economies to profits netted through the illegal ivory trade.
What happens to a river when a dam is removed?
October 9, 2014 07:17 AM - Oregon State University
A study of the removal of two dams in Oregon suggests that rivers can return surprisingly fast to a condition close to their natural state, both physically and biologically, and that the biological recovery might outpace the physical recovery. The analysis, published by researchers from Oregon State University in the journal PLOS One, examined portions of two rivers — the Calapooia River and Rogue River. It illustrated how rapidly rivers can recover, both from the long-term impact of the dam and from the short-term impact of releasing stored sediment when the dam is removed.
How "Natural" are Naturally Labeled Foods?
October 8, 2014 08:46 AM - ClickGreen Staff, ClickGreen
A wide variety of packaged food that carry the label "natural" on US supermarket shelves were found to contain substantial amounts of genetically modified organisms (GMO), according to product testing organization Consumer Reports. Tests on dozens of common food products including breakfast cereals, crisps and infant formula found almost all of them contained recognizable levels of GMOs. The research results has led to Consumer Reports to now call for the mandatory labeling of GMOs in food and a ban on the "natural" label, which suggest products don't contain the controversial ingredients.
A new concept in EV charging
October 8, 2014 08:07 AM - BOB SHETH, Electric Forum
There is no doubt that the EV industry is here to stay, too much money has been invested and too many people have transferred over from old-style technology. However, while EV technology itself continues to develop, efficiencies are improved and prices continue to fall, there have been ongoing concerns about recharging systems of the future. However, a company by the name of Ubitricity in Germany may well have come up with a solution which could be the answer to all our prayers!
