Systems to harness the sun's energy typically generate either electricity or heat in the form of steam or hot water. But a new analysis by researchers at MIT shows that there could be significant advantages to systems that produce both electricity and heat simultaneously.
NOAA scientists have found that pressure from increasing coastal populations, ship and boat groundings, marine debris, poaching, and climate change are critically threatening the health of the Florida Keys ecosystem. Many historically abundant marine resources such as green sea turtles and coral habitat continue to be at risk with low rates of recovery.
Pesticides and pollutants are related to an alarming 450 percent increase in the risk of spina bifida and anencephaly in rural China, according to scientists at The University of Texas at Austin and Peking University.
The U.S. Environmental Protection Agency (EPA) recently announced that Dry Creek Rancheria in Sonoma County, Calif., has gained authority to administer its own water quality programs under the federal Clean Water Act.
If courts were able to award appropriate punitive damages that punish wrongdoers at a level tied to a company's financial worth, then businesses big and small would be at risk of being put out of business by punitive damages, thus deterring unconscionable offenses and bad behavior in the first place.
In a new camera trap survey in the world’s most biologically diverse landscape, researchers for the Wildlife Conservation Society have identified more individual jaguars than ever before.
Studies of ant populations in Borneo reveal an unexpected resilience to areas of rainforest degraded by repeated intensive logging, a finding which conservationists hope will lead governments to conserve these areas rather than allow them to be cleared and used for cash crop plantations.
When contractors talk of green buildings, they mean environmentally-friendly and energy saving. Add agricultural experts in the plans, and “green” also means plants – vibrant ornamental grasses, shrubs and flowers in park-like settings on the roofs of multistoried office buildings in cities.
Lower emissions, less noise, more quality of life – all good reasons to turn to electricity where mobility is concerned. If the EU has its way, we will all be driving only electric cars in the major cities of Europe by the year 2050. A beautiful goal, but experts are going even further than that: citizens can forego a car of their own and share electric vehicles.
Smithsonian scientists have discovered two new, closely related bee species: one from Coiba Island in Panama and another from northern Colombia. Both descended from of a group of stingless bees that originated in the Amazon and moved into Central America, the ancestors of Mayan honeybees. The presence of one of these new species on Coiba and Rancheria Islands, and its absence from the nearby mainland, is a mystery that will ultimately shed light on Panama's history and abundant biodiversity.
NWO researcher Liesbeth Bakker made this discovery during her research into the food preferences of fish. The discovery turns our current understanding of the relationships between plants and animals on its head.
The Ryland Group Inc. will pay a civil penalty of $625,000 to resolve alleged Clean Water Act violations at its construction sites.
Scientists are reporting that household washing machines seem to be a major source of so-called "microplastic" pollution that they now have detected on ocean shorelines worldwide.
A bi-partisan, geographically diverse group of twenty-six state Attorneys General joined forest owners and industry groups in filing briefs asking the U.S. Supreme Court to reverse the 9th Circuit Court of Appeals' ruling that rainwater runoff from forest roads used for timber harvest is a "point source" of water pollution under the Clean Water Act.
Natural gas mining has drawn fire recently after claims that hydraulic fracturing, an increasingly popular technique for tapping hard-to-reach reservoirs, contaminates groundwater. Surface lakes, rivers and streams may also be at risk.
New research has found that hurricane activity is 'clustered' rather than random, which has important long-term implications for coastal ecosystems and human population. The research was carried out by Professor Peter Mumby from The University of Queensland Global Change Institute and School of Biological Sciences, Professor David Stephenson and Dr. Renato Vitolo (Willis Research Fellow) at the University of Exeter's Exeter Climate Systems research centre.
Scientists from the University of Gothenburg, Sweden, have launched a tool that uses the actual conditions to determine the maximum possible magnitude of solar incidence - in a whole town, a neighbourhood, or a particular roof.
Rivers and streams in the United States are releasing enough carbon into the atmosphere to fuel 3.4 million car trips to the moon, according to Yale researchers in Nature Geoscience. Their findings could change the way scientists model the movement of carbon between land, water and the atmosphere.
It is becoming more and more common to install solar panels on roofs in order to obtain green electricity, but not all roofs are equally suitable.
This year marks 25 years since the passage of the federal Emergency Planning and Community Right-to-Know Act (EPCRA). The act was passed in 1986 as a part of the reauthorization for Superfund. EPCRA has played a significant role in protecting people’s health and the environment by providing communities and emergency planners with area-specific information on toxic chemical releases.
