Cleantech Investing Hit $3.9B in 2006

Excerpt:
"The Cleantech Network issued a report this week that looks back at cleantech venture investing in 2006. It was a “watershed period” in the industry, according to the group, as investment in the sector rose 70 percent in 2006 and the market began to see its first successful cleantech IPOs and M&As. Venture investors put $3.9 billion into cleantech companies in North America, Europe and Israel — $1.6 billion more than in 2005."
