Preface This assessment report is a product of the Distributed Wind Working Group of the National Wind Coordinat- ing Committee (NWCC). The NWCC was formed in 1994 as a collaborative endeavor composed of represen- tatives from diverse sectors including electric utilities and their support organizations, state utility commis- sions, state legislatures, environmental organizations, wind equipment suppliers and developers, green power marketers, consumer advocates, agriculture and economic development organizations, and local, regional, state, tribal and federal agencies. The NWCC identifies issues that affect the use of wind power, establishes dialogue among key stakeholders, and catalyzes activities to support the development of an environmentally, economically and politically sustainable commercial market for wind energy. The NWCC Distributed Wind Working Group was formed to examine and assess distributed-wind develop- ment options in the United States. In addition to this document, the National Wind Coordinating Committee has many other wind-energy-related materials on its web site: www.nationalwind.org.
