In a first-ever for the U.S., a company focused entirely on wind energy is planning to come public, with Noble Environmental Power Inc. registering an IPO to list on the Nasdaq later this year.

Based in Essex, Connecticut, USA ., Noble Environmental registered earlier this month with the Securities and Exchange Commission to raise as much as US$ 375 million through an initial public offering. The amounts actually raised in IPOs can vary dramatically from the registration figure; Noble Environmental has not set a price range, share size or date yet for its offering.
