The American wind market provided its strongest quarter year yet as 2008 drew to a close, bringing online around 4.5 GW in the final three months of the year -- more than the combined total of 4.2 GW for the first nine months. The stunning final quarter achievement puts the US on track to have installed a record 8.5 GW for 2008, bringing its combined wind power capacity to well over 25 GW across the country. Iowa and Texas saw the greatest growth, each bringing more than 1 GW online. Emphasising how strongly the wind market has diversified geographically from its concentration in California in the 1980s and 1990s to the Central Plains and Midwest this decade, Iowa at 2442 MW is now within 220 MW of overtaking California as the number two top state for wind power behind Texas. New York brought online 455 MW through the year's end and Kansas followed with 349 MW. The Northeast state of New Hampshire put itself on the commercial wind map for the first time with the completion of Iberdrola's 24 MW Lempster wind project.
