Can’t Take the Heat? ‘Cool Walls’ Can Reduce Energy Costs, Pollution

A study by scientists at Berkeley Lab modeled several different types and ages of homes, retail stores, and office buildings in cities across California and the U.S. and found that sunlight-reflecting “cool” exterior walls can save as much or more energy than sunlight-reflecting cool roofs in many places.

With Little Training, Machine-Learning Algorithms Can Uncover Hidden Scientific Knowledge

Researchers have shown that an algorithm with no training in materials science can scan the text of millions of papers and uncover new scientific knowledge. A Berkeley Lab-led team collected 3.3 million abstracts of published materials science papers and fed them into an algorithm. By analyzing relationships between words the algorithm was able to predict discoveries of new thermoelectric materials years in advance and suggest as-yet unknown materials as candidates for thermoelectric materials.

Exploring New Ways to Control Thermal Radiation

Planck’s Law, which describes electromagnetic radiation from heated bodies, forms the basis of quantum theory. However, with the advent of micro- and nanotechnology, it is easy to fabricate materials where Planck’s Law will not hold. In a study published in Nature Communications, researchers at Berkeley Lab set out to explore how deviations from Planck’s Law

Four Berkeley Lab Scientists Named AAAS Fellows

Four Berkeley Lab scientists – Allen Goldstein, Sung-Hou Kim, Susannah Tringe, and Katherine Yelick – have been named Fellows of the American Association for the Advancement of Science (AAAS), the world’s largest general scientific society. They are among the 416 scientists awarded the distinction of AAAS Fellow this year.

Berkeley Lab Wins 2018 R&D 100 Award; Special Recognition Award for Cyclotron Road Startup

An online data management tool for water/energy retrofits, and a device that recycles carbon dioxide into renewable fuels have both been recognized in the 2018 R&D 100 Awards given to Berkeley Lab.

Q&A: How to Protect Yourself and Your Family From Wildfire Smoke

Berkeley Lab indoor air experts Brett Singer and Woody Delp advise: stay indoors, consider a mask, limit activities, use air filtration systems, or even build your own.

Machine Learning to Help Optimize Traffic and Reduce Pollution

Applying artificial intelligence to self-driving cars to smooth traffic, reduce fuel consumption, and improve air quality predictions may sound like the stuff of science fiction, but researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have launched two research projects to do just that.

Ancient Pigment Can Boost Energy Efficiency

Egyptian blue, derived from calcium copper silicate, was routinely used on ancient depictions of gods and royalty. Previous studies have shown that when Egyptian blue absorbs visible light, it then emits light in the near-infrared range. Now a team led by researchers at Lawrence Berkeley National Laboratory has confirmed the pigment’s fluorescence can be 10 times stronger than previously thought.

Online Tool Fills Gap for Energy Retrofit Projects

A national online energy data management system is transforming how energy retrofit projects implemented by a wide variety of users – including local, state, and federal governments – develop projects and track performance.

Report Confirms Wind Technology Advancements Continue to Drive Down Wind Energy Prices

Wind energy pricing remains attractive, according to an annual report released by the U.S. Department of Energy and prepared by Lawrence Berkeley National Laboratory (Berkeley Lab). At an average of around 2 cents per kilowatt-hour (kWh), prices offered by newly built wind projects in the United States are being driven lower by technology advancements and cost reductions.
