Air Conditioning: Cooler on the Inside, Hotter on the Outside!
We all love to be comfortable in our homes and businesses. We use air-conditioning to provide comfortable temperatures indoors. Air conditioners work basically by moving hotter air from inside to outside. Does this have an impact on climate? Global warming? A team of researchers from Arizona State University has found that releasing excess heat from air conditioners running during the night resulted in higher outside temperatures, worsening the urban heat island effect and increasing cooling demands. "We found that waste heat from air conditioning systems was maximum during the day but the mean effect was negligible near the surface. However, during the night, heat emitted from air conditioning systems increased the mean air temperature by more than 1 degree Celsius (almost 2 degrees Fahrenheit) for some urban locations," said Francisco Salamanca, a post-doctoral research scientist at Arizona State University's School of Mathematical and Statistical Sciences. >> Read the Full Article
Why don't building owners install modern controls?
Commercial buildings use large amounts of electricity and natural gas. Significant reductions in energy use can be achieved by installing new modern systems but this requires a significant capital cost, It is possible to install modern control systems at much lower cost and these can also significantly reduce energy use, and improve comfort at the same time! A new study by the Pacific Northwest National Laboratory shows that commercial buildings could cut their heating and cooling electricity use by an average of 57 percent with advanced energy-efficiency controls, according to a year-long trial of the controls at malls, grocery stores and other buildings across the country. The study demonstrated higher energy savings than what was predicted in earlier computer simulations by the same researchers. >> Read the Full Article

Volvo and Electric charging on the go
There are electric satellites from Boeing and electric planes from Airbus, so why not electric roads, brought to you by Volvo Group? Volvo, in collaboration with the Swedish Transport Administration, is studying the potential for building electric roads where city busesâ€”built by Volvo, of courseâ€”can be charged from electricity in the road while the bus is in operation. >> Read the Full Article
Technology reducing cost of solar panels by half
A world expert on solar panels will today outline how his pioneering work is set to significantly improve the performance of solar panels whilst simultaneously contributing to their cost being reduced by half. The technology will be commercialized within the next five years. >> Read the Full Article

Green Success: Heaven Hill Distilleries Steps up Recycling Efforts
Beginning operation in 1934 after the repeal of Prohibition, Heaven Hill Distilleries located in Bardstown, Kentucky has become the largest family-owned and operated producer and marketer of distilled spirits in the nation. Bottling over 12 million cases of spirits in 2012, one could imagine the amounts of leftover materials that could either go to a landfill or be recycled. Fortunately, Heaven Hill decided to try recycling as part of their KY EXCEL membership. KY EXCEL is Kentucky's free, voluntary environmental leadership program open to individuals, communities, and organizations that wish to improve and protect Kentucky's environment in ways that extend beyond state requirements. Kim Harmon, the Environmental Compliance Manager at the distillery, says, "When we started our recycling program in 2011, we tried to find everything that could be recycled and vendors to take the materials. We recycle paper labels, bands around pallets, aerosol cans, brown paper packing, blue drums, label backing, cardboard, plastic and glass." >> Read the Full Article
Coral Reefs: Who's protecting whom?
According to a recent study, delicate coral reefs are protecting hundreds of millions of people around the world from stronger storms, rising seas, and flooding. The internationally supported study finds that coral reefs reduce the wave energy that would otherwise impact coastlines by 97 percent. >> Read the Full Article
