A Harmonized Dataset of Ground-Mounted Solar Energy in the US with Enhanced Metadata

Solar energy generating systems are critical components of our expanding energy infrastructure, yet available datasets remain incomplete or not publicly available–particularly at the sub-array level. Combining the best open access datasets in the US with image analysis on freely available remotely-sensed imagery, we present the Ground-Mounted Solar Energy in the United States (GM-SEUS) dataset, a harmonized, open access geospatial and temporal repository of solar energy arrays and panel-rows. GM-SEUS v1.0 includes over 15,000 commercial- and utility-scale ground-mounted solar photovoltaic and concentrating solar energy arrays (186 GWDC) covering 2,950 km2 and includes 2.92 million unique solar panel-rows (466 km2). We use …

Gateway to Green

India’s ports have the potential to become key hubs in the global green hydrogen transition. Beyond serving as traditional transit points, they can evolve into dynamic energy ecosystems by seamlessly integrating green hydrogen into their value chains. This transformation would not only accelerate India’s clean energy shift but also strengthen its role in global trade while unlocking new revenue streams through bunkering, refueling, and value-added services.

A robust Common User Infrastructure (CUI) framework will be key to developing green hydrogen facilities. Strategically located ports can cater to both domestic and export markets, leveraging their proximity to industrial clusters and existing …

DOE Staff Crunch Slows American Energy Innovation

DOE Staff Crunch Slows American Energy Innovation (September 2025) explores the relationship between the U.S. Department of Energy’s (DOE) staffing levels and funding to catalyze and implement American energy innovation. This brief is part of EFI Foundation’s Modernizing American Energy Innovation series.

For decades, DOE has played a critical role in supporting American energy innovation and increasing U.S economic competitiveness in global markets. DOE was built to advance national goals, including the development of new energy resources, lowering costs to consumers, and building out America’s infrastructure.

In recent years, there has been broad support to expand DOE’s mission to fund …

Community Resilience Mapping Tool Catalog

Across the electric power sector, planning with equity and resilience has never been more urgent and never more achievable. Today’s utility leaders are navigating unprecedented change: surging demand from electrification, AI, and data centers; the need to strengthen the grid for resilience; and the responsibility to ensure communities are not left behind. At the same time, leaders now have access to an expanding ecosystem of data, from natural hazard risk and infrastructure vulnerability to equity indicators and DER hosting capacity.

But navigating this range of resources can be time-consuming and complex. That’s why SEPA created this Catalog: to help energy …

2025 Transportation Electrification in the Southeast Report

This year’s report provides a snapshot of the electric vehicle (EV) market at a particularly pivotal political inflection point. Produced by Atlas Public Policy in partnership with the Southern Alliance for Clean Energy (SACE), the report examines data from July 2024 through June 2025 for six states across the Southeast — Alabama, Florida, Georgia, North Carolina, South Carolina, and Tennessee — across six market indicators: manufacturing investments; anticipated jobs; EV sales; charging infrastructure deployment; utility investments; and public funding.…

National Nuclear Security Administration: Additional Steps Needed to Improve Cost Estimates for Fixed Price Subcontracts

NNSA spends millions of dollars on hundreds of construction projects each year to maintain and modernize the research and production infrastructure at its eight nuclear security enterprise sites. NNSA relies on M&O contractors at its sites to manage the day-to-day activities associated with these construction projects. For less costly projects, M&O contractors may use fixed-price subcontracts to procure the services of subcontractors.

The report accompanying the Senate bill for the National Defense Authorization Act for FY 2024 includes a provision for GAO to review NNSA’s use of fixed-price construction subcontracts. This report examines (1) the extent to which M&O contractor …

National Transmission Planning Study

Improving and expanding electric transmission infrastructure in the U.S. is critical to ensuring consumers across the country have access to reliable, affordable power when and where they need it and to enable us to integrate new, clean sources of energy generation into the grid. To understand the transformation needed to ensure the U.S. electric transmission system continues to reliably serve the nation’s electricity customers as the power sector evolves and transitions to cleaner resources, the U.S. Department of Energy’s Grid Deployment Office led the multiyear National Transmission Planning Study (NTP Study) in partnership with the National Renewable Energy Laboratory (NREL) …

Regionalizing Transition Intelligence

Financial institutions face a critical challenge in assessing corporate transition planning: the absence of regional context. Although climate targets and decarbonization strategies are increasingly common in corporate disclosures, they often overlook the local economic, policy, and infrastructure conditions that shape the pace and feasibility of transition. This disconnect limits the usefulness of assessments, hindering the ability of financial institutions to effectively manage climate-related risks and opportunities.…

Recalibrating the Role of Banks in the Energy Transition

We are at an important inflection point in climate finance. Net-zero aligned targets set with good intentions are now met with challenges from all sides — technical, economic, legal, and reputational. While some fear a retreat in ambition, we see this as an opportunity to check our assumptions, ask better questions, and ultimately chart a new path forward. We need a recalibration — one that will ensure that the role of banks in the energy transition is rightsized to focus on deals, not just disclosure.

In the last decade, banks have overhauled governance, launched net-zero strategies, and built internal capability …
