Miranda Ballentine has devoted her career to accelerating the role of advanced energy in national security, economic prosperity, and solving climate change. In September, 2018, Miranda became the founding CEO of Renewable Energy Buyers Alliance (REBA), an alliance of large clean energy buyers, developers, and service providers who, together with NGO partners, are unlocking the marketplace for all non-residential energy buyers to lead a rapid transition to a cleaner, prosperous, zero-carbon energy future. This new membership-based organization is building a resilient, zero-carbon energy system where every organization has a viable, expedient, and cost-effective pathway to renewable energy. Miranda joins REBA after serving as CEO of Constant Power, Inc., a Toronto-based developer, integrator, and operator of distributed energy resources. Prior to CPI, Miranda was Managing Director of Rocky Mountain Institute’s Business Renewables Center, a member-based platform that accelerates corporate purchasing of renewable energy. BRC members were involved in 100% of corporate renewables large-scale deals in 2018. From 2014-2017, Miranda served President Obama as the 4th Assistant Secretary of the Air Force for Installations, Environment, & Energy, where she was responsible for a $9 billion annual energy budget in addition to environmental programs for 9 million acres of land, 200 miles of coastline, 600,000 acres of forestland, and 270,000 acres of wetlands. She launched the Resilient Energy Demonstration Initiative (REDI), which developed smart, cyber-secure microgrids, including a “Future Forward Operating Base.” Previously, Miranda was Director of Sustainability for Global Renewable Energy at Walmart Stores, Inc, where she led a team in fifteen countries to develop strategies toward Walmart’s goal to be supplied by 100% renewable energy. These programs identified $1+ billion in potential annual energy savings and 9 million metric tons of avoided greenhouse gas potential. In 2013, Miranda was selected to join the World Economic Forum’s Young Global Leaders. She has a BS degree from Colorado State University and an MBA from George Washington University.
