Fix-a-Leak Week
March 20, 2014 10:59 AM - Robin Blackstone, ENN

According to WaterSense, an Environmental Protection Agency Partnership Program, household leaks waste more than a trillion gallons of water annually. Our urgency to conserve often depends upon what part of the country we live. But officials predict that at least 36 states that will experience some sort of water shortage.

COLLEGIATE CORNER: Offshore oil drilling: is it really necessary?
March 18, 2014 10:32 AM - Christian Ramirez, Class of 2015, Wakefield High School, Arlington, VA

As we all know, oil is a very important energy resource the world needs for its everyday life. It is known that not only do most of the countries on the planet use it, but also it is a scarce resource, which means that in the near future, there will no longer be enough available oil that could be drilled and processed for future endeavors. The demand for oil has increased significantly throughout the past few years and other ways of obtaining this resource must be used more often. A form of oil drilling has emerged which is dangerous and is known as offshore drilling. Sounds like a good plan at first, going to the ocean where more oil can be found and at a faster rate, but is it really worth it? There should be an alternate to offshore drilling because of the many horrific and unfair problems that it brings to Americans, animals, and the overall environment.

An insulation trifecta
March 18, 2014 07:31 AM - Chris Miller , Sierra Club Green Home

A savvy do-it-yourselfer can come up with a dozen unconventional uses for insulation (spray foam as packing material, anyone?), which makes it tricky to find basic information online when you're just dipping your toes in to the DIY pool. Here is an introduction to the three basic types of insulation and their most common uses: blown-in, spray foam and batt/blanket insulation.

Rooftop considerations amidst climate change
March 13, 2014 11:54 AM - Robin Blackstone, ENN

As the realities of climate change set in, so too are realizations that building technologies impact both internal and external environments. The percentage increase of asphalt and blacktopped roofs create urban heat islands. Resultantly cities have become earth's newest desserts exhibiting high temperatures and arid conditions with little vegetation. Urban expansion as a stand-alone factor (omitting greenhouse gas-induced climate change considerations) is expected to raise temperatures by roughly six degrees. Because of this, scientists are now exploring new technologies to cope with the new reality.

Big Ben May Get a Solar Face Lift
March 13, 2014 08:04 AM - Sara Lozanova, Triple Pundit

In an effort by the U.K. Parliament to reach the ambitious goal of reducing greenhouse gas emission by 34 percent by 2020, the House of Commons is now looking to the parliamentary estate and considering installing solar panels on the face of Big Ben in London. Parliamentary passholders were submitting ideas for reducing carbon emissions and boosting energy efficiency on the estate, when the solar idea was suggested.

Sustainable urban lawns
March 12, 2014 01:16 PM - robin Blackstone, ENN

Concern for the homogenization of America's urban landscape prompted a recent research study into the care and maintenance of residential landscapes. The study demonstrated fewer similarities than expected but the concern, according to researchers is that "Lawns not only cover a larger extent [of land] than any other irrigated 'crop' in the U.S., but are expected to expand in coming decades. The researchers go on to point out that the potential homogenization of residential lawn care has emerged as a major concern for carbon, nitrogen, phosphorus and water flows."

Stonehenge, acoustically speaking
March 10, 2014 04:46 PM - University of Bristol newsroom

Why did the builders of Stonehenge choose to transport giant bluestones hundreds of kilometers from Wales to Salisbury Plain? Dr. George Nash from Bristol's Department of Archaeology and Anthropology is involved in research, which is taking a novel approach to solving the mystery.

COLLEGIATE CORNER: Trash talk: Ocean Dumping
March 10, 2014 11:01 AM - McKaylee Reavis, Class of 2015, Wakefield High School, Arlington, VA

Remember the excitement that filled your body when your parents told you the family was going to go to the beach? Remember the excitement slowly leaving your body when you witnessed the trash that covered the beach for miles? Ocean dumping has become a major problem for marine life and the people who enjoy its many benefits. Many marine animals have suffered from the trash in the water and people have suffered from the sight of trash filling the ocean and cluttering the beaches ruining their supposed beautiful day. Industries, cities, and militaries have been dumping their waste into the ocean for years now. One solution to prevent this problem is to impose stricter restrictions on ocean dumping that range from pedestrian waste to toxic nuclear hazard.

DOE Sets New Commercial Refrigeration Energy Efficiency Standards
March 7, 2014 08:01 AM - Andrew Burger, Triple Pundit

Following through on President Barack Obama's Climate Action Plan, the Department of Energy (DOE) on Feb. 28 issued new energy efficiency standards for commercial refrigeration equipment. Over the ensuing 30 years, it's projected that the new standards will reduce carbon pollution by 142 million tons — the equivalent of that produced by generating electricity for 14.3 million U.S. homes — while also saving businesses as much as $11.7 billion on energy bills.

How much water do YOU use each day?
March 6, 2014 09:22 AM - Indiana University Newsroom, Indiana University Bloomington

Many Americans are confused about the best ways to conserve water and have a slippery grasp on how much water different activities use, according to a national online survey conducted by Indiana University Assistant Professor, Shahzeen Attari. Experts say the best strategy for conserving water is to focus on efficiency improvements such as replacing toilets and retrofitting washing machines. However, the largest group of the participants, nearly 43 percent, cited taking shorter showers, which does save water but may not be the most effective action. Very few participants cited replacing toilets or flushing less, even though toilets use the most volume of water daily.
