IEEE Spectrum: Trouble Brewing for Wind?

Amid much good news for wind--an onging global surge in wind energy installations, the go-ahead from the U.S. government for the immensely controversial Cape Wind project--comes a report detailing a sharp rise in wind operating costs and poor performance relative to other countries. Prepared by the independent business intelligence service Wind Energy Update, the Wind Energy Operations & Maintenance Report finds that current O&M costs are two or three times higher than first projected and that there has been a 21 percent decrease in returns on investments in wind farms. O&M costs were found to be especially high in the United States, "now the world's largest wind power market."
