By using advanced lighting and automated shades, scientists from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) found that occupants on one floor of a high-rise office building in New York City were able to reduce lighting energy usage by nearly 80 percent in some areas.

The dramatic results emerged at a “living laboratory” set up to test four sets of technologies on one 40,000 square-foot floor of a building.

With growing risks to the nation’s electrical grid from natural disasters and as a potential target for malicious attacks, the U.S. Department of Energy (DOE) and the U.S. Department of Homeland Security (DHS) should work closely with utility operators and other stakeholders to improve cyber and physical security and resilience, says a new congressionally mandated report by the National Academies of Sciences, Engineering, and Medicine.  

The grid remains vulnerable to diverse threats that can potentially cause extensive damage and result in large-area, prolonged outages that could cost billions of dollars and cause loss of life, the report found. The committee that conducted the study and wrote the report recommended ways to make the grid more resilient through the development and demonstration of technologies and organizational strategies that minimize the likelihood that outages will happen, reduce the impacts and speed recovery if they do, all the while developing mechanisms for continual improvements based on changing threats.

The Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) will lead a new $9 million project aimed at removing technical barriers to commercialization of enhanced geothermal systems (EGS), a clean energy technology with the potential to power 100 million American homes.

Berkeley Lab will partner with seven other DOE national labs and six universities to develop field experiments focused on understanding and modeling rock fractures, an essential element of geothermal systems. Scientists will use the Sanford Underground Research Facility (SURF) in South Dakota to create small-scale fracture networks in crystalline rock 1,500 meters below ground.

After a century of markets dominated by a few types of wheat and white flour, ancient and heritage wheat varieties are making a comeback.

A new Northwestern University study suggests that paying people to conserve their trees could be a highly cost-effective way to reduce deforestation and carbon emissions and should be a key part of the global strategy to fight climate change.

The study, led by Seema Jayachandran, associate professor of economics in the Weinberg College of Arts and Sciences at Northwestern, sought to evaluate how effective “Payments for Ecosystems” (PES) is at reducing deforestation. PES is a program in which people are given financial rewards for pro-environment behaviors.
