Our Team

Our team believes that the COVID-19 pandemic, the economic recession, patterns of racial injustice, and the persistent and real dangers presented by climate change can all be lenses through which we view our work as we in America re-build our economy generally and our energy economy specifically. Our pledge at the Center for the New Energy Economy is that, as we participate in the hard work of rebuilding America’s energy economy, we do so with the lens of equity and justice at the forefront of our consciousness.
