About the Map

The "Energy, Environment and Policy in the U.S." map is developed by Kenneth B. Medlock III and Elsie Hung at the Center for Energy Studies as an online, interactive tool to visualize and highlight the geospatial nexus of energy, environment, policy, and society in the United States. The map displays the nation’s critical energy infrastructure, environmental points of interest, and relevant election and demographics statistics at different levels of granularity. Users can select each layer to hide/display and explore the facility level details with clickable tool tips. In 2023, we also released a drilled-down community map to highlight additional data on environmental justice and energy transitions at the Census block group level.

We hope to stimulate and facilitate pertinent discussions and research with this interactive tool. More importantly, it allows the users to effectively navigate key energy and environmental issues with a clear and complete picture of the nation’s infrastructure and demography. The map will be updated regularly to incorporate additional, relevant layers and reflect the most recent data available. 

Please share feedback and suggestions you might have by contacting the authors at elsie.hung@rice.edu.
