"High carbon-based energy prices, global resource competition and increasingly favorable policy frameworks provide stronger than ever fundamental drivers for cleantech investors, and we foresee continued growth over 2008 as the cleantech market cycle moves from early adoption to mainstream driver of wealth and job creation."
