DOE's Funding and Markets for Wind Energy and Solar Cell Technologies
RCED-99-130: Published: May 14, 1999. Publicly Released: May 28, 1999.
Pursuant to a congressional request, GAO provided information on wind and photovoltaic technologies, focusing on: (1) how much the Department of Energy (DOE) has spent on research and development; (2) how DOE's objectives for its programs have changed over time; and (3) the characteristics of the markets for these technologies.
GAO noted that: (1) since fiscal year 1978, DOE has provided more than $3 billion to develop wind and photovoltaic technologies; (2) since the 1970s, the objectives of the wind and photovoltaic programs have expanded from fundamental research to include larger market shares for U.S. wind turbine companies and increased domestic and international sales by U.S. photovoltaic companies; and (3) the markets for wind and photovoltaic technologies have grown rapidly in recent years and now extend internationally.
