"We used two different models to analyze a number of alternative scenarios of annual wind power capacity expansion to better understand the impacts of high levels of wind-generated electricity production on wind energy manufacturing and installation rates. The results of these approaches indicate that achieving levels of wind penetration of 20% of national electrical energy demand in the 2020 to 2030 time frame is possible without overwhelming the ability of U.S. industry to meet these demands."@en . . . . .
