AUSTIN, Texas — Homes with solar panels do not require on-site storage to reap the biggest economic and environmental benefits of solar energy, according to research from the Cockrell School of Engineering at The University of Texas at Austin. In fact, storing solar energy for nighttime use actually increases both energy consumption and emissions compared with sending excess solar energy directly to the utility grid.(more…)
Researchers at the Yale School of Forestry & Environmental Studies have discovered that diseased trees may be a significant cause of global warming. The university’s researchers tested the trees at the Yale Myers Forest near their campus in Connecticut and discovered that rotting trees release a significant amount of methane gas, a highly flammable type of natural gas that can cause climate change in large quantities. The trees at the Yale Myers Forest produce emissions that are equivalent to burning 40 gallons of gas per acre of forest per year.
In their academic report on this matter, “Elevated Methane Concentrations in Trees of an Upland Forest,” the Yale University research team noted that trees that release methane gas look just like ordinary trees on the outside. However, on the inside, they’re being eaten alive by fungus. And the fungus that rots these trees helps fuel methane production because it makes the trees a hospitable breeding ground for methanogens, tiny organisms that create methane. (more…)
New research from North Carolina State University shows that federal requirements governing diesel engines of new tractor trailer trucks have resulted in major cuts in emissions of particulate matter (PM) and nitrogen oxides (NOx) – pollutants that have significant human health and environmental impacts.
“These requirements for new emission control technologies have increased costs for truck owners and operators, and we wanted to know whether there was any real benefit,” says Dr. Chris Frey, professor of civil, construction and environmental engineering at NC State and co-author of a paper describing the research. “We found that there is a huge reduction in both PM and NOx emissions.” (more…)
WASHINGTON — A thick blanket of yellow haze hovering over Houston as a result of chemical pollution from petroleum products may be getting a little bit thinner, according to a new study. But the new findings — which have implications for petrochemical-producing cities around the world — come with a catch, says a team of scientists who participated in the research.

Can light-colored rooftops and roads really curb carbon emissions and combat global climate change?
The idea has been around for years, but now, a new study by researchers at Lawrence Berkeley National Laboratory that is the first to use a global model to study the question has found that implementing cool roofs and cool pavements in cities around the world can not only help cities stay cooler, they can also cool the world, with the potential of canceling the heating effect of up to two years of worldwide carbon dioxide emissions.
