Air Conditioning: Cooler on the Inside, Hotter on the Outside!
May 25, 2014 09:30 AM - Editor, ENN
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.
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.
Technology reducing cost of solar panels by half
May 21, 2014 10:00 AM - Click Green Staff, ClickGreen
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.
Fighting air pollution with innovation and technology
May 19, 2014 10:46 AM - ENN Editor
Air pollution has become one of the world's biggest threats to the future of our planet. Chronic air pollution shortens our lives and the lives of the ecologies around us. In parts of Asia, where air pollution is most pervasive, food crops and other plants are exhibiting signs of stress due to low air quality.
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.
A greener barbecue

Memorial Day, the unofficial start of summer and outdoor cooking season is right around the corner. Unfortunately, outdoor cooking is too often connected with a tremendous amount of waste. Make this year's summer the "summer of green" with these eco-friendly alternatives for a low-impact summer barbecue:
Industrial-sized rain barrel research in Washington State
May 12, 2014 10:15 AM - ENN Editor
In an effort to reduce the amount of polluted runoff reaching Puget Sound, the Port of Seattle is hosting a two-year study site for two unique metal boxes, which will bloom into rain gardens and help reduce pollutants.
Scotland provides guidance to wind farms for the protection of bird life
May 12, 2014 09:49 AM - Click Green Staff, ClickGreen
An innovative guide for wind farms is to be produced by the Scottish Government, industry and charities to help protect bird life. The Scottish Windfarm Bird Steering Group, made up of the Scottish Government, Scottish Natural Heritage, RSPB Scotland and Scottish Renewables, has already spent more than £50,000 on a series of studies.
President Obama details an Action Plan on Climate
May 10, 2014 07:12 AM - Alexis Petru, Triple Pundit
On the heels of the administration's release of the Third National Climate Assessment report, President Barack Obama today announced an array of executive actions and public and private sector commitments to increase solar installations and energy efficiency improvements, strengthen energy efficiency standards, and bolster the solar industry workforce. The actions and pledges that Obama laid out will deploy enough solar energy to power nearly 130,000 homes, cut carbon emissions by the equivalent of taking 80 million cars off the road and save businesses $26 billion on their energy bills, the White House said in a statement. "We don't look backwards. We look forward. We don’t fear the future," Obama said on why it's time to conserve energy, promote renewables and take action on climate change.
National Priorities List of Superfund sites adds seven
May 9, 2014 07:18 AM - Editor, ENN
The U.S. Environmental Protection Agency (EPA) is added seven hazardous waste sites to the National Priorities List (NPL) of Superfund sites. They include two facilities in York, NE and single facilities in Norphlet, AK; Windham, ME; Fairfield, NJ; Ridgewood, NY and Collierville, TN. Superfund is the federal program that investigates and cleans up the most complex, uncontrolled or abandoned hazardous waste sites in the country to protect people's health and the environment.
