Yesterday's Mercury News article "The Cleantech Cliff: Global Venture Capital Investment Plunged 33 Percent in 2012" discusses the difficulties that Cleantech investing experienced in the past year.  The article indicates that global Cleantech investment in 2012 was $6.46 billion, down from $9.61 billion invested in 2011, a decline of 33%.

Reasons for the decline include:
  • Low natural gas prices make it more difficult for renewable energy projects to compete
  • Capital intensive deals are out of favor with venture capitalists, after failures like MiaSole.
  • Global economic uncertainty also took a toll

Wired.com has posted an article by Juliet Eilperin entitled "Why the Clean Tech Boom Went Bust" that is a good read and insightful.  Worthy weekend reading.  Here's the link:   http://www.wired.com/magazine/2012/01/ff_solyndra/

 
 
There's an interesting article in Forbes about Chinese venture capital firms investing in US cleantech firms.  The link is here:  http://www.forbes.com/sites/yonicohen/2011/12/05/cleantech-startups-look-to-china-for-venture-capital/

The article discusses that Chinese venture capital firms, including GSR Ventures, Tsing Capital and DT Capital Partners, are investing in international cleantech deals that have a China connection.  In addition, the article highlights that the Chinese government is providing financial incentives and is fast-tracking administrative approvals for these companies.  Finally the size of the domestic Chinese market provides great market opportunity.
