More evidence of strong VC interest in clean tech from Dow Jones VentureWire:

"Financing for companies attempting to develop new sources of renewable energy, new processes and materials for manufacturing, and new technology for managing energy use, rose to a six-year high of $513 million in the first quarter of 2006, according to data from Cleantech Venture Network LLC. "

Most of the money (70%) went to energy generation technologies.

Bottom Line: Good news for the sector. There are also more examples of investments outside the predominant VC focus on solar technologies.
