Maps
Here you will find information about renewable energy resources and states with specific policies designed to foster the development of markets for renewable energy technologies organized on maps of the United States.
Renewable Energy Resources
Find state maps showing renewable energy resources.
Geothermal Resource Maps for 13 States
DOE's Idaho National Energy Engineering Laboratory (INEEL) publishes geothermal resource maps for 13 western states and the western United States as a whole.
Hydropower Resource Assessments by State
DOE's Idaho National Energy Engineering Laboratory (INEEL) publishes a resource assessment report for every state except Delaware, which was excluded because of its very limited hydropower resources.
Wind Energy Resource Maps by State
EERE's Wind Powering America publishes wind energy resource maps for most states. Some are developed by researchers who work for DOE's Wind and Hydropower Program; others are developed by the states.
