*Berkeley Lab joint report offers a variety of scenarios to reduce emissions to 80% below 1990 levels.*

Berkeley, CA — In the next 40 years, California’s population is expected to surge from 37 million to 55 million and the demand for energy is expected to double. Given those daunting numbers, can California really reduce its greenhouse gas emissions to 80 percent below 1990 levels by 2050, as required by an executive order? Scientists from Lawrence Berkeley National Laboratory who co-wrote a new report on California’s energy future are optimistic that the target can be achieved, though not without bold policy and behavioral changes as well as some scientific innovation.

The report, titled “California’s Energy Future—The View to 2050,” draws a series of energy system “portraits” showing how California can meet its ambitious emissions targets using a combination of measures and energy sources that may include electrification, enhanced efficiency, nuclear energy, renewable energy sources, grid modernization, and carbon capture and sequestration (CCS).

Such highly coveted technical capabilities as the observation of single catalytic processes in nanoreactors, or the optical detection of low concentrations of biochemical agents and gases are an important step closer to fruition. Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab), in collaboration with researchers at the University of Stuttgart in Germany, report the first experimental demonstration of antenna-enhanced gas sensing at the single particle level. By placing a palladium nanoparticle on the focusing tip of a gold nanoantenna, they were able to clearly detect changes in the palladium’s optical properties upon exposure to hydrogen. (more…)

Desert Dust Reduces Colorado River Flow

Dark-colored dust that settles on snow in the Upper Colorado River Basin makes the snow melt early and robs the Colorado River of about 5 percent of its water each year, says a new study co-authored by researchers from the University of Colorado at Boulder-based Cooperative Institute for Research in Environmental Sciences, or CIRES.
