ENERGY STAR's first multifamily properties announced today
November 13, 2014 08:31 AM - ENERGY STAR
Roughly one-third of the U.S. population lives in the country’s 500,000 multifamily buildings, and they spend $22 billion on energy every year. Until this year, apartment and condo managers lacked the tools to measure how much energy they were wasting and compare their performance nationwide. Meanwhile, energy costs for renters have risen by 20 percent over the past decade.
Today, a new era of savings will be ushered in when the U.S EPA announces the first set of multifamily properties to earn the ENERGY STAR certification. The ENERGY STAR first became available to the sector this September, after a three-year partnership with Fannie Mae to develop the scoring system for multifamily properties.
New study says fracking chemicals are "no more toxic" than common household substances
November 12, 2014 01:21 PM - University of Colorado, Boulder
The “surfactant” chemicals found in samples of fracking fluid collected in five states were no more toxic than substances commonly found in homes, according to a first-of-its-kind analysis by researchers at the University of Colorado Boulder. Fracking fluid is largely comprised of water and sand, but oil and gas companies also add a variety of other chemicals, including anti-bacterial agents, corrosion inhibitors and surfactants. Surfactants reduce the surface tension between water and oil, allowing for more oil to be extracted from porous rock underground. In a new study published in the journal Analytical Chemistry, the research team identified the surfactants found in fracking fluid samples from Colorado, Louisiana, Nevada, Pennsylvania and Texas. The results showed that the chemicals found in the fluid samples were also commonly found in everyday products, from toothpaste to laxatives to detergent to ice cream.
How would you feel if electric vehicles were the only ones allowed in center cities?
November 9, 2014 04:42 AM - , Electric Forum
The subject of making electric vehicles compulsory in city centres in the UK, and indeed many other areas of the world, is one which keeps popping up time and time again. The Liberal Democrat party in the UK has been pushing for greater adoption of electric vehicles within city centres and, don’t shout this, a ban on diesel and petrol vehicles. This is now something of a hot topic and one which will continue to appear in the political domain as we approach general and local elections.
How would you feel about making city centres a no-go area for petrol and diesel vehicles? Is electric vehicle technology of sufficient reliability to support such a dramatic and controversial move?
How Offshore Wind Farms Affect Marine Species
October 17, 2014 06:07 AM - University of Maryland Center for Environmental Science
Offshore wind power is a valuable source of renewable energy that can help reduce carbon emissions. Technological advances are allowing higher capacity turbines to be installed in deeper water, but there is still much unknown about the effects on the environment. In a recent paper, University of Maryland Center for Environmental Science researcher Helen Bailey and colleagues review the potential impacts of offshore wind developments on marine species and make recommendations for future monitoring and assessment as interest in offshore wind energy grows around the world.
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.
Can renewables supply 100% of world's power by 2050?
October 16, 2014 06:08 AM - Tim Radford, The Ecologist
A global low-carbon energy economy is not only feasible - it could actually double electricity supply by 2050, while also reducing air and water pollution, according to new research. Even though photovoltaic power requires up to 40 times more copper than conventional power plants, and wind power uses up to 14 times more iron, the world wins on a switch to low-carbon energy. These positive findings are published in the Proceedings of the National Academy of Sciences by Edgar Hertwich and Thomas Gibon, of the Norwegian University of Science and Technology Department of Energy and Process Engineering.

Fracking Footprint Seen From Space
October 10, 2014 08:38 AM - ClickGreen Staff, ClickGreen
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 US 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.
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.
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.
