This note provides a technical and market overview of the wind power industry as of 2007. Growing off a small base, investments in wind energy technology and applications are rapidly expanding worldwide. Oil price increases, energy security, and renewable energy demand are driving investments and technology innovations as well as new entrants into the industry. As a consequence of component supply falling behind demand, prices have risen; state, federal, and international government policies will also have a significant impact on supply and demand in the years that follow.
