Workshop
The U.S. electricity system, known collectively as "the grid," is increasingly integrating a complex array of distributed energy resources (DERs) such as solar panels, wind turbines, batteries, and small-scale energy generators. By harnessing a diverse range of power sources and often generating energy close to the point of use rather than only in central power plants, DERs offer unprecedented flexibility in electricity generation and management. However, the imperative to maintain and improve the operational integrity of the grid as it takes on increasing quantities of DERs represents an emerging critical issue, particularly as demand for electricity enters a period of significant growth in many places across the United States.
To consider the research needs, operational standards, regulatory approaches, market incentives, and other facets relevant to ensuring the operational integrity of the grid as it integrates complex distributed elements, the National Academies of Sciences, Engineering, and Medicine convened a workshop on Electricity System Operability and Reliability under Increasing Complexity in Washington, DC, on June 17-18, 2024. The workshop convened representatives from government, industry, academia, and nongovernmental organizations to examine a variety of challenges that grid operators face in maintaining reliable and equitable electricity service, along with emerging technologies and capabilities that may impact grid operations and reliability.

Workshop
For many Black Americans, trust in science, engineering, and medicine (SEM) institutions is affected by historic and current contexts, with significant consequences including exacerbating health and economic inequities for this population. Many SEM professionals recognize the importance of building trust with the Black community, and are looking for sustainable and effective ways to earn and nurture that trust.
To advance SEM issues within the Black community, the Roundtable on Black Men and Black Women in Science, Engineering, and Medicine at the National Academies of Sciences, Engineering, and Medicine convened a public workshop to examine local, national, and global strategies used by groups such as the Black Church to build institutional trust. The workshop, held December 14-15, 2022, was structured to identify organizations that have demonstrated success in building and maintaining trust with Black communities, highlight best practices for SEM professionals to develop sustainable and effective relationships with the Black community, and examine how communication with Black communities influences trust and acceptance of SEM institutions.

Workshop
Atypical weather events, such as extreme tropical cyclones, pose substantial threats to life, property and livelihoods in the U.S. and worldwide. Despite major advances in forecasting capabilities, communicating about extreme weather events with decision-makers and the public carries considerable challenges but also provides opportunities for innovation. Decisions surrounding extreme weather events often involve making tradeoffs between different degrees and varieties of risks. For example, deciding whether or when to issue an evacuation order ahead of a tropical cyclone entails tradeoffs between the risks to lives posed by the event and the risks to livelihoods posed by the financial costs of evacuations or relocations.
In early 2024, the National Academies held a workshop on risk communication around extreme tropical cyclones and other atypical climate events. Participants aimed to identify opportunities and challenges for risk communication as well as lessons about community engagement and communication concerning other climate events. Over the course of the workshop, participants addressed various facets of risk communication, including the importance and difficulty of clearly communicating uncertainty to the general public; the importance of understanding the needs of various audiences in the context of effective communication; preparedness as a critical component of an effective response; and the often-profound ways that strong partnerships and relationships across sectors and offices can impact and improve risk communication.

Lagging indicators in occupational safety and health are required reporting figures that provide an industry-standard metric to measure the number of employees injured annually or impacted by a recordable injury. Recognizing the weaknesses of traditional lagging indicators to proactively manage occupational safety, many organizations and industries have emphasized safety leading indicators; that is, metrics to identify safety-related activities to consider before an incident occurs.
NCHRP Synthesis 637: Tracking Safety Leading Indicators to Improve DOT Employee Safety Performance, from TRB's National Cooperative Highway Research Program, explores issues related to safety leading indicator practices used by state departments of transportation (DOTs) to track and prevent occupational injuries and other incidents. The synthesis also includes findings from a survey related to safety leading indicators of practices used by state DOTs.
