Giant Chinese Utilities Datang and Huaneng are doing roadshows for the IPOs of their Renewable Energy Arms which would raise more than Billion Dollars Each.Note Green Utilities have become a separate Green Investment Class with lots of Asian and European Utilities already doing an IPO of their Green Subsidiaries or are in the process of doing so.However 2010 has been a bad year for Green Energy Stocks and Green Utilities have been no different.While First Wind Holdings a pure play USA Wind Farm Developer failed to get listed despite lowering its Issue Price,Indian Orient Green Power and Italian Enel Green Power have performed miserably even after listing at a much lowered stock price.Despite the negative sentiment towards Green Utilities mainly due to the Headwinds being faced by Wind Industry in 2010,Green Utilities are one of the safest ways to invest in the Alternative Energy Sector given the nascent highly volatile nature of the industry.
