Weather deserves medal for clean air during 2008 Olympics [
Wed Dec 28 11:17:17 EST 2011]
New research suggests that China's impressive feat of cutting Beijing's pollution up to 50 percent for the 2008 Summer Olympics had some help from Mother Nature. Rain just at the beginning and wind during the Olympics likely contributed about half of the effort needed to clean up the skies, scientists found. The results also suggest emission controls need to be more widely implemented than in 2008...

Gone with the wind: Why the fast jet stream winds cannot contribute much renewable energy after all [
Wed Nov 30 10:00:00 EST 2011]
The assumption that high jet steam wind speeds in the upper atmosphere correspond to high wind power has now been challenged by new research. Taking into account that the high wind speeds result from the near absence of friction and not from a strong power source, scientists found that the maximum extractable energy from jet streams is approximately 200 times less than reported previously....

Carbon mitigation strategy uses wood for buildings first, bioenergy second [
Tue Nov 22 14:33:33 EST 2011]
A new study is first to focus on the extra carbon savings that can be squeezed from trees when wood not suitable for long-term building materials is used for bioenergy: Depending on the process used, ethanol from woody biomass emits less greenhouse gas than an equivalent amount of gasoline, between 70 percent and a little over 100 percent less. In contrast, corn ethanol reduces greenhouse gas emis...

Corn gene boosts biofuels from switchgrass [
Fri Nov 18 15:14:14 EST 2011]
Introducing a special corn gene into switchgrass was found to significantly boost the viability of the switchgrass biomass as a feedstock crop for advanced biofuels. The gene, a variant of the Corngrass1 gene, holds the switchgrass in a perpetual juvenile state, more than doubling its starch content and making it easier to convert its polysaccharides into fermentable sugars....

Large differences in the climate impact of biofuels, Swedish research finds [
Tue Nov 15 17:53:53 EST 2011]
When biomass is combusted the carbon that once was bound in the growing tree is released into the atmosphere. For this reason, bioenergy is often considered carbon dioxide neutral. Research from Sweden, however, shows that this is a simplification. The use of bioenergy may affect ecosystem carbon stocks, and it can take anything from 2 to 100 years for different biofuels to achieve carbon dioxide...
