Bio: Brian Castelli, Executive Vice President for Programs and Development

Brian T. Castelli brings 30 years of national and international experience in the energy field, including expertise in energy efficiency, renewables, emission reductions, and electricity demand reduction, to the Alliance to Save Energy as executive vice president for programs & development.  Prior to joining the Alliance’s senior management team in July 2005, Castelli ran his own energy consulting firm. 

Among his varied endeavors, he was the federal energy liaison for the California Energy Commission, one of the nation’s premier state energy offices; a principal with the Center for Energy and Climate Solutions, a one‑stop shop helping businesses and states adopt high-level strategies for saving energy and cutting pollution; and a consultant to the Electric Power Research Institute (EPRI) where he organized a High Technology Council (comprised of communications and information technology leaders) to advise EPRI’s Intelligent Grid program.

Castelli also consulted with the National Association of State Energy Officials (NASEO) where, on behalf of the National Energy Technology Laboratory, he conducted a series of public workshops in 14 western states on advanced, highly-efficient turbines and fuel cells that involved manufacturers, developers, utilities, and state and federal energy and environmental officials.

As a presidential appointee, Castelli served as chief of staff to the U.S. Department of Energy’s assistant secretary for energy efficiency and renewable energy from 1994 to 2001.  He managed 550 staff and more than $1 billion in programs and research, development, and deployment initiatives and directed the development and implementation of energy policies and programs.  

Castelli also led and participated in missions to Western Hemisphere, European, and former Soviet Union countries and was also deeply involved in developing energy-efficiency measures for the eventual closure of the nuclear reactors in Chornobyl, Ukraine.

Prior to DOE, Castelli was appointed in 1988 by Gov. Bob Casey to the Pennsylvania Energy Office (PEO), for three years as deputy director for administration and public affairs and then as executive director, through 1994.  As executive director he ran the commonwealth’s energy policies and programs, managed the state energy office and the Pennsylvania Energy Development Authority, and took the lead on responding to energy emergencies.  

Notably, he developed a revolving loan fund for energy-efficiency measures and a “Green Buildings” program for cutting energy use and costs in all commonwealth-owned or operated buildings, and he drafted legislation for and implemented an alternative fuel program.

As the PEO’s deputy director, Castelli’s responsibilities included administration, budgeting, public information, and energy program policies.  He also created more effective financial assistance and energy outreach programs and served as the PEO’s liaison to delegations of state and federal legislators.  


Earlier in his career, Castelli was vice president of finance for The National Center for Appropriate Technology; senior vice president and cofounder of CEXEC; and financial analyst with the Federal Energy Administration.  He has authored many articles, studies, and reports on energy-related issues, served on various boards of directors, and made presentations in many state, national, and international forums and conferences. 

In August 2006, Castelli became a member of the Board of Directors of Conservation Services Group, a nonprofit energy services firm headquartered in Westborough, Mass., with 14 offices nationwide.

Castelli holds two degrees from the University of Pennsylvania, a bachelor of science in chemical engineering and an MBA in industrial/environmental management from the university’s Wharton School.
