IEA Examines Whether Carbon Pricing Makes Energy-Efficiency Policies Redundant

To date, many academics and government officials have argued that putting a price on carbon – most commonly through taxes or emissions trading – is all that is needed to overcome every possible barrier to delivering cost-effective energy efficiency improvements.

Michigan Researchers See Plentiful Lithium Resources for Electric Vehicles

Researchers from the University of Michigan and Ford Motor Co. have assessed the global availability of lithium and compared it to the potential demand from large-scale global use of electric vehicles.

Tiny, Symbiotic Fungi May Hold the Key to Adapting Plants to Climate Change

Rice – which provides nearly half the daily calories for the world’s population – could become adapted to climate change and some catastrophic events by colonizing its seeds or plants with the spores of tiny naturally occurring fungi, U.S. Geological Survey-led research shows.

Calcifying Microalgae Are Witnesses of Increasing Ocean Acidification

Coccolithophores, a certain group of algae, form thinner calcite skeletons when the pH value in the ocean drops. In marine ecosystems, changes in the degree of calcification are much more pronounced than presumed to date based on laboratory tests. These changes have an impact on the global carbon balance since the examined microalgae influence the carbon dioxide exchange between ocean and atmosphere.

Slowing Climate Change by Targeting Gases Other Than Carbon Dioxide

Carbon dioxide still plays a major role in climate change, but other greenhouse gases contribute to the problem.

LED Bulb Wins Energy Departments L Prize Competition

The Department of Energy's L Prize challenged the lighting industry to develop high-performance, energy-saving replacements for conventional light bulbs that will save American consumers and businesses money.

Study: Toxic Chemicals Found in Children's Car Seats

More than 150 child car seats, including Graco, Fisher Price, Britax and Evenflo, were tested for hazardous chemicals. See the best and worst list.

Nature's Expert Witnesses: Plants Tell of Environmental Pollution

This practice of sampling and analyzing tissue from trees and other plants to determine the presence of contaminants in soil and groundwater holds promise because it gives engineers a quick, accurate and inexpensive way to measure the extent of environmental pollutants without having to dig into the ground.



Study Underway to Improve Food Security in Southern Appalachia

While the popularity of locally and regionally grown food is on the rise among Americans, food accessibility remains a major concern for those with limited financial resources.

USGS Survey Says Fallen Leaves and Rain Both Add Same Amount of Mercury to the Environment

Fallen autumn leaves transfer as much, if not more, hazardous mercury from the atmosphere to the environment as does precipitation each year, according to recent U.S. Geological Survey research.

Study: Microbes Consumed Surprisingly Large Amount of Oil in Gulf Spill Slick

Researchers found that bacterial microbes inside the slick degraded the oil at a rate five times faster than microbes outside the slick—accounting in large part for the disappearance of the slick some three weeks after Deepwater Horizon's Macondo well was shut off.

Some Replacements for CFC-Containing Refrigerants Much More Potent GHGs than CO2

While international climate talks remain deadlocked, the Montreal Protocol has been methodically eliminating some of the worst chemicals contributing to global warming.

New Research Suggests Radioactive Decay is Key Ingredient Behind Earth's Heat

New research suggests that nearly half the Earth's heat comes from the radioactive decay of materials beneath the surface, according to a large international research collaboration that includes a Kansas State University physicist.

Aerosols Affect Climate More than Satellite Estimates Predict

Aerosol particles, including soot and sulfur dioxide from burning fossil fuels, essentially mask the effects of greenhouse gases and are at the heart of the biggest uncertainty in climate change prediction.

Tips Tuesday: How to Save Energy While on Vacation

Summer is the ideal season for vacations, and whether you plan to spend your days beach bumming, hiking with friends or visiting out-of-town relatives, these tips will help reduce your at-home energy consumption as much as possible while you are away.

Round-the-Clock Solar Power May Be the Stuff of Dreams No Longer

The biggest hurdle to widespread implementation of solar power is the fact that the sun doesn't shine constantly in any given place, so backup power systems are needed for nights and cloudy days. But a novel system designed by researchers at MIT could finally overcome that problem, delivering steady power 24/7.

Researchers Discover Catalyst That Could Help Replace Petroleum-Derived Products

Researchers in the Pacific Northwest have developed a new catalyst material that could replace chemicals currently derived from petroleum and be the basis for more environmentally friendly products, including octane-boosting gas and fuel additives, bio-based rubber for tires and a safer solvent for the chemicals industry.

Tide's Retreat and Advance Not as Constant as You Might Think

The ebb and flow of the ocean tides, generally thought to be one of the most predictable forces on Earth, are actually quite variable over long time periods, in ways that have not been adequately accounted for in most evaluations of prehistoric sea level changes.

DOE Panel: Let Communities Volunteer to Host Waste Facilities

The Blue Ribbon Commission on America's Nuclear Future also says currently available revenues are sufficient and a new, non-DOE nuclear waste management program should be established.

Tequila Plant Could Fuel Vehicles, Help Reduce Emissions

The agave plant has not yet been widely cultivated as a fuel source, but it promises some significant advantages over existing sources of ethanol such as sugarcane and corn.
