A study led by Berkeley Lab’s Ronald Cohen has shown that nitrogen oxide emission controls are improving the notorious air quality in California’s San Joaquin Valley.
Air Quality in San Joaquin Valley Improving: Study Shows Controls to Reduce Nitrogen Oxide Emissions Are Working
Looking strictly at the economic costs and benefits of three different roof types—black, white and “green” (or vegetated)—Berkeley Lab researchers have found in a new study that white roofs are the most cost-effective over a 50-year time span. While the high installation cost of green roofs sets them back in economic terms, their environmental and amenity benefits may at least partially mitigate their financial burden.
President Obama has named Andrew Sessler, award-winning theoretical physicist, acclaimed humanitarian, and former director of Berkeley Lab, as a recipient of the Enrico Fermi Award, the government’s oldest and most prestigious prizes for scientific achievement.
Current official inventories of methane emissions, a potent greenhouse gas released from landfills, livestock ranches and oil and gas facilities, may be underestimated both nationally and in California by a factor of about 1.5, according to new research from Berkeley Lab and others.
A unique inside look at the electronic structure of a highly touted metal-organic framework (MOF) as it is adsorbing carbon dioxide gas should help in the design of new and improved MOFs for carbon capture and storage.
For decades, no one worried much about the air quality inside people’s homes unless there was secondhand smoke or radon present. Then scientists at Lawrence Berkeley National Laboratory made the discovery that the aggregate health consequences of poor indoor air quality are as significant as those from all traffic accidents or infectious diseases in the United States. They are now working on turning those research findings into science-based solutions, including better standards for residential buildings and easier ways to test for the hazardous pollutants.
If you think it’s been unusually hot lately, just wait—by the end of the century, temperatures in California are expected to rise significantly. Looking at a range of future climate scenarios, Larry Dale, an economist at Berkeley Lab, found that California may need as much as 30 to 40 percent more generation and transmission capacity per capita by the end of the century because of the negative effect of higher temperatures on equipment performance.
More Potent than Carbon Dioxide, Nitrous Oxide Levels in California May be Nearly Three Times Higher Than Previously Thought
Using a new method for estimating greenhouse gases that combines atmospheric measurements with model predictions, Lawrence Berkeley National Laboratory (Berkeley Lab) researchers have found that the level of nitrous oxide, a potent greenhouse gas, in California may be 2.5 to 3 times greater than the current inventory. At that level, total N2O emissions—which are believed to come primarily from nitrogen fertilizers used in agricultural production—would account for about 8 percent of California’s total greenhouse gas emissions.
