  • Carbon-Free Electricity

Chaz leads RMI’s Clean Competitive Grids team within RMI’s Carbon-Free Electricity program. The CCG team works to ensure that we build the necessary markets and grid infrastructure required for electricity to be the clean energy backbone of a carbon-free economy. The work includes wholesale markets, transmission, distribution, and equitable deep decarbonization planning.


Before joining RMI in 2018, Chaz fabricated and studied new photovoltaic materials and devices at the National Renewable Energy Laboratory and built a wireless building controls system at Terralux, an LED lighting startup. Chaz has five patents and is the lead author of more than 40 peer-reviewed scientific publications.

Why I Love Working At RMI

“Every day I wake up and ask myself ‘What is the most important thing I can do today to create a sustainable, equitable, and carbon-free future?’ – and then I get to work on that.”
