Bethel Tarekegne joined Pacific Northwest National Laboratory (PNNL) in 2021 and is an energy equity and renewables researcher. Tarekegne’s work focuses on understanding the social equity implications of renewable energy technologies. She is currently exploring the equity and justice implications of energy storage for the Department of Energy, Office of Electricity’s Energy Storage program, discovering ways that energy storage can benefit underserved communities. Bethel’s work in this space sets the framework for applying energy justice principles to storage technologies. She is also investigating how storage can provide local non-energy benefits by developing fundamental data and metrics to measure these benefits.
