Hybrid Vehicles More Fuel Efficient In India, China Than in U.S.

March 31, 2014

What makes cities in India and China so frustrating to drive in—heavy traffic, aggressive driving style, few freeways—makes them ideal for saving fuel with hybrid vehicles, according to new research by scientists at Lawrence Berkeley National Laboratory. In a pair of studies using real-world driving conditions, they found that hybrid cars are significantly more fuel-efficient in India and China than they are in the United States.

New Ideas Needed to Meet California’s 2050 Greenhouse Gas Targets: Berkeley Lab Study

November 4, 2013

California is on track to meet its state-mandated targets for reducing greenhouse gas emissions for 2020, but it will not be able to meet its 2050 target without bold new technologies and policies. This is the conclusion of the California Greenhouse Gas Inventory Spreadsheet (GHGIS), a new model developed by the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) to look at how far existing policies and technologies can get us in emissions reductions.

Less Toxic Metabolites, More Chemical Product

October 29, 2013

By preventing the build-up of toxic metabolites in engineered microbes, a dynamic regulatory system developed at JBEI can help boost production of an advanced biofuel, a therapeutic drug, or other valuable chemical products. The system has already been used to double the production in E. coli of amorphadiene, a precursor to the premier antimalarial drug artemisinin.

Hydrogen Fuel From Sunlight:

August 29, 2013

Berkeley Lab researchers at the Joint Center for Artificial Photosynthesis have developed a way to interface a molecular hydrogen-producing catalyst with a visible light absorbing semiconductor. With this approach, hydrogen fuel can be produced off a photocathode using sunlight.

No Evidence of Residential Property Value Impacts Near U.S. Wind Turbines, a New Berkeley Lab Study Finds

August 27, 2013

After analyzing more than 50,000 home sales near 63 wind facilities in 27 counties across nine U.S. states, Berkeley Lab researchers were unable to uncover any impacts to nearby home property values. “We find no evidence that operating turbines have any measureable impact on home sales prices,” says Ben Hoen, the study’s lead author.

Size Matters as Nanocrystals Go Through Phases

August 26, 2013

Berkeley Lab researchers at the Molecular Foundry have demonstrated that as metal nanocrystals go through phase transformations, size can make a much bigger difference than scientists previously believed.

Installed Price of Solar Photovoltaic Systems in the U.S. Continues to Decline at a Rapid Pace

August 12, 2013

The installed price of solar photovoltaic (PV) power systems in the United States fell substantially in 2012 and through the first half of 2013, according to the latest edition of Tracking the Sun, an annual PV cost tracking report produced by Berkeley Lab.

A Path to Better MTV-MOFs:

August 8, 2013

A team of Berkeley Lab and UC Berkeley researchers have developed a method for accurately predicting the ability of MTV-MOFs (multivariate metal organic frameworks) to scrub carbon dioxide from the exhaust gases of fossil fuel power plants.

New Study Finds that the Price of Wind Energy in the United States Is Near an All-Time Low

August 6, 2013

Annual wind power additions in the United States achieved record levels in 2012, while wind energy pricing is near an all-time low, according to a new report released by the U.S. Department of Energy and prepared by Berkeley Lab. But even with a short-term extension of federal tax incentives now in place, the wind power industry is facing uncertain times, in part due to low natural gas prices and continued policy uncertainty.
