Ernst & Young has published a good overview of Cleantech investment in the US last year. The total amount invested was just short of five billion dollars, according to data from VentureSource. Overall investment activity was flat 2011 compared to 2010, which is not surprising in view of the tough conditions in the global economy, say the E&Y analysts.
