Eric Wanless

Sr. Associate (Industry & Electricity)


Eric is a Sr. Associate with RMI’s industry and electricity practices, where he specializes in energy strategy development and implementation as well as design innovation for electric utilities, heavy industry, and corporations. He has been involved with RMI in various capacities since starting as a fellow in 2005.

RMI Projects

  • Industrial energy—Eric’s experience in working with industrial clients includes the radical redesign of a large refinery to demonstrate concrete deep energy and cost savings, developing an achievable low-carbon vision for one of the largest mining companies in the world, creating a renewable energy and efficiency strategy for a large consumer products manufacturer, and evaluating carbon offset opportunities for a global IT company.
  • Electric utility planning and analysis—Eric has worked with a diverse set of electric utilities, including Duke Energy and the San Francisco Public Utilities Commission. He has also evaluated the feasibility and impact of very high penetrations of renewable energy and energy efficiency for global heavy industry sites.
  • Smart grid and real-time demand response—Eric led an internal RMI effort to evaluate the value of real-time demand response as a tool to enable large penetrations of variable renewable energy resources.


Before joining RMI, Eric worked with the Research and Policy group at Ecova where he led an effort to identify, quantify, and pursue significant cost-effective energy savings in computers and other IT equipment. This effort leveraged deep engineering teardowns and analysis, energy policy expertise, and ultimately led to the development of more aggressive voluntary and mandatory efficiency standards on state, federal, and international levels.

Eric has also worked with the Natural Resources Defense Council implementing collaborative energy efficiency policy in California and as a senior field instructor teaching leadership and communication with the National Outdoor Leadership School.
