Stephen Doig, Ph.D.

Managing Director



Stephen Doig is a Managing Director at Rocky Mountain Institute where he leads work on the transformation of island economies to renewable energy and energy efficiency and co-leads the Institute’s work to radically increase the adoption of distributed renewable energy, especially solar PV.  His islands work is underpinned by his broad experience across all of RMI’s work including buildings, electricity, industry and transportation.  He has led teams to deliver results in diverse areas such as a 40% decrease in energy use at the Empire State Building, a data center that uses 80% less energy, an energy strategy for a major U.S. utility that incorporated 30% renewable energy by 2030 and established RMI’s work on lowering the cost of solar PV.  He also led the team for RMI’s book, Reinventing Fire, which outlines the transition of the U.S. to renewable energy and applied that approach to the comprehensive energy plan for Connecticut.

His current work in solar PV is focused making this resource available to lower income communities.


Prior to joining RMI in 2007, Stephen worked at McKinsey & Co. where he focused on operational excellence including procurement, manufacturing, network configuration, product development and global sourcing across a wide range of industries ranging from integrated steel to healthcare in the UK.  He also had a leadership role in McKinsey’s Sustainability practice where he focused on energy efficiency in a wide range of sectors. 

Stephen served as a senior advisor to the U.S. Air Force on energy efficiency where he led a team that developed a strategy to reduce energy use by 30% in 10 years and drive up adoption of renewable energy.  He’s held faculty positions at Wharton School at the University of Pennsylvania and at Carleton College.
