Study uncovers dirty little secret: Soil emissions are much-bigger-than-expected component of air pollution

...ogen oxides produced by huge fires and fossil fuel combustion are a major component of air pollution. They are t...scattered ground-based measurements of burning and combustion and then extrapolating a global total for nitrogen oxide emissions, the new work used actual observa...

Ethanol and biodiesel from crops not worth the energy

...y to produce these fuels than you get out from the combustion of these products." Although Pimentel advocates the use of burning biomass to produce thermal energy (to heat homes, for example), he deplores the use of biomass for liquid fuel. "The government spends more than $3 billion a year to subsidize ethano...

Hopkins researchers discover genetic switch that turns off an oxygen-poor cell's combustion engine

...the hybrid car, cells use oxygen and the internal combustion engine at higher speeds and rely on an electric e...rion, when oxygen is ample. But like the internal combustion engine, this process generates pollutants or toxic oxygen molecules. At lower oxygen levels, when...

Tropical forest CO2 emissions tied to nutrient increases

...uding in tropical forests, a result of fossil-fuel combustion and crop fertilization activities, said Townsend. "Human activity has changed the availability of nitrogen all over the world, especially in the last 50 years," he said. "This study was surprising because of the large effect both of these nutrients h...

Scientific issues associated with carbon-neutral energy sources such as cellulosic ethanol

...tration of atmospheric CO2, such as that caused by combustion of fossil fuel, would lead to the warming of the earth," Somerville commented. "It is apparent that he [Arrhenius] was correct and that we must develop alternative sources of energy." The earth receives approximately 4,000 times more energy from th...

Biodiesel won't drive down global warming

...cross their overall life cycles from production to combustion in cars. The results show that biodiesel derived from rapeseed grown on dedicated farmland emits nearly the same amount of greenhouse gas emissions (defined as CO2 equivalents) per km driven as does conventional diesel. However, if the land u...

New biofuels process promises to meet all US transportation needs
