According to the Cleantech Venture Network's Q1 report (released yesterday), cleantech VC investments in the first quarter of 2005 were $335.9M, up a reported 4.8% from the same period a year earlier.
While clean energy investments went down slightly, investments in advanced materials and nanotech rose the fastest among cleantech segments.
For the period, cleantech investments were 7.3% of all North American VC investments -- up from 6.6% a year earlier. Still a small portion, but continuing to grow.
