Join us for a National Lab Discovery Series webinar highlighting a novel manufacturing process from the National Renewable Energy Laboratory (NREL) that reduces the cost and increases the scalability of high efficiency III-V solar cells. Named "dynamic hydride vapor phase epitaxy," or D-HVPE, this process is especially promising for high-performance solar applications--such as high-altitude drones, space-based power systems, and remote or off-grid energy platforms--where efficiency, reliability, and lightweight materials are essential.

This training will serve as an overview of how to conduct an energy and water treasure hunt. It will provide an overview of the treasure hunt process, a review of technical topics typically covered, and serve as a preparation for the on-site hands-on Treasure Hunt of the U.S. Department of Energy's own headquarters building--the James V. Forrestal Building in Washington, D.C.

Baldcypress (Taxodium distichum) and pondcypress (Taxodium distichum var. imbricarium) are two species commonly found in forested wetland ecosystems of the southeastern United States. Both species can improve water quality, provide wildlife habitat, mitigate flood waters, and help control erosion, making them ecologically important trees. However, baldcypress and pondcypress are both hosts for the baldcypress leafroller (Archips goyerana), a native defoliating pest first documented in southeastern Louisiana in 1983. Baldcypress leaf roller defoliation events can cause reduced tree growth, crown dieback, and, in some cases, host tree mortality. But what do we know about this pest and how do we reduce its impact?

Discover how strategic exterior upgrades can do more than enhance curb appeal--they can drive real energy savings. This session will explore innovative solutions like high-performance windows, cool roofing systems, and exterior insulation panels. Learn how these technologies can boost building efficiency and long-term value.

Some people need a quick prompt to remind them. Others respond to evidence that it makes a difference or that it's a normal thing everyone does. Nudging people to consistently recycle or adopt waste reduction practices isn't easy but it is possible. Key to unlocking zero waste behavior is a thoughtful messaging strategy grounded in the distinct values, social context and other factors that guide a person's actions. This webinar will feature two sustainability behavior experts discussing messaging strategies rooted in science, from extensive CBSM-style campaigns to simple signage prompts. Their presentations will cite best practices and real-world case studies of public engagement initiatives that have resulted in meaningful improvements.

This webinar will spotlight successful utility energy service contract (UESC) projects that are enabling federal agencies to meet critical statutory and policy goals related to energy resilience and cost efficiency.

In this workshop, participants will explore best practices for analyzing fleet utilization and right-sizing using a sample fleet dataset. Using an example fleet dataset, attendees will learn how to identify low-use vehicles and prioritize fleet assets based on data-driven insights. The session will provide a practical framework and best practices for determining which vehicles to flag for potential elimination or downsizing to reduce fleet costs, while still maintaining agency fleet mission requirements.

A growing number of smaller and more rural communities are busting the myth that green infrastructure is a "nice to have" bonus part of a project to manage stormwater. Green infrastructure is no longer only available to larger, urban utilities. Join WaterNow to learn about how municipalities in Lancaster, PA, Harrisburg, PA, and Caledon, ON are using green infrastructure to help meet their stormwater challenges. These communities are successfully integrating green infrastructure into their projects to improve quality, reduce localized flooding, and achieve ecological benefits.

Improved HVAC controls can optimize building performance, reduce energy and maintenance costs by 10-20%, and enhance occupant comfort. In this webinar, hear from leading organizations about how they harnessed the power of smart thermostats and advanced building controls. Attendees will also discover resources to support small and medium-sized buildings, including the 'stairway to better buildings' and the importance of setpoints and scheduling.

Vines are woody or herbaceous plants with relatively long stems. Vines are typically known for their twining or climbing nature. In the US, we have several non-native species of vines that have become problematic and are now considered invasive species. These invasive vines can cause problems such as outcompeting native plant communities, growing into dense thickets, girdling trees, and being extremely difficult to remove. But what are some examples of invasive vines that we find here in the US? What kind of problems do each species cause, and how can they be managed? In this webinar, Chris Evans will discuss the biology, impact, and management of some commonly found invasive vines.

This training will focus on the practical application of identified resilience solutions in federal infrastructure projects. Participants will learn how to utilize utility programs, as well as financial assistance programs like Assisting Federal Facilities with Energy Conservation Technologies (AFFECT) and Energy Resilience and Conservation Investment Program (ERCIP), to fund projects that enhance resilience at their sites. While performance contracting and appropriations will be discussed, the training will emphasize other actionable strategies to implement resilience at the site level.

Stormwater assets – the drainage systems and control measures installed to manage stormwater – are vulnerable to system failures that cause upsets, flooding, and system damage if they are not properly maintained and upgraded when necessary. Cities, counties, and states manage roadway stormwater assets to keep waterways clean and prevent localized flooding. Stormwater asset management planning is a proven approach that helps provide reliable levels of service to customers, helps plan system renewal and upgrades, and minimizes the total cost of owning and operating the assets. In this webinar, speakers from three state Departments of Transportation will showcase a variety of approaches to stormwater asset management in the roadway context.

2025 is set to be a busy legislative year against per- and polyfluoroalkyl substances (PFAS), with increasing state-level reporting obligations, use restrictions, and/or bans across a range of consumer product sectors including personal care, cookware, textiles, electronics and food packaging. At the federal level, the EPA continues to make progress towards its PFAS strategic roadmap, and Canada is also taking new measures to regulate the manufacture, import and use of these substances. Manufacturers, importers and retailers can all expect to continue to see further action to address PFAS, so it is vital to ensure your business is prepared for compliance requirements. Taking place on 18 September, this final day of Regulatory Summit North America – available to book separately or as part of the full summit – will bring together expert stakeholders to address the latest regulatory, legal and scientific developments on PFAS, offer practical advice and lessons learnt for compliance and solutions for managing PFAS in your supply chain.
