Senior Associate
  • Carbon-Free Electricity

Maria Castillo is a senior associate in RMI’s Carbon-Free Electricity team, where she focuses on the issues of energy affordability and environmental justice through data analysis. She designed and led the publishing of utility-level energy burden data and coauthored multiple publications on LIHEAP, utility shut-offs, and federal energy policy. Her work on the state of customer affordability has proven the importance of centering the needs of low-income and marginalized households in the energy transition.


Prior to RMI, she worked as a research assistant at Columbia University’s Center for Global Energy Policy, where she contributed to the Lancet Countdown’s Health and Climate Change 2020 US Brief on the health impact of natural gas venting and flaring.
