“Urban Renewal” Surrounding Florida Solar Plants: A Study On Low-Carbon Gentrification, Megan Amber Grove

USF Tampa Graduate Theses and Dissertations

Renewable energy and sustainable living are growing trends in Florida as the state “develops” rural landscapes and “redevelops” urban ones, resulting in neighborhood changes, including displacement of low-income and minority populations (LIMP). Solar energy has not historically been a root cause of such changes, but in recent years it has increasingly accompanied neighborhood development which prioritizes the interests of the elite and middle class. As such, it has become a contributor to “urban renewal,” which must be addressed to avoid future LIMP displacement. This study used geospatial and data science technologies and techniques to empirically explore and analyze urbanization and …
