Despite some battered stocks and an overall credit crunch, fund managers will continue to introduce green/clean tech investment vehicles in 2009.

According to a survey released Thursday from the Social Investment Forum (SIF), an association for socially and environmentally responsible investment professionals, clients are still asking for new clean tech investing opportunities.

Of the 14 companies surveyed, 10 expressed interest in launching new clean/green oriented investment vehicles during 2009.

While some solar companies such as SunPower are seeing revenues rapidly increase, many solar stocks are taking a beating. "Clean energy stocks have been crushed this year despite the fact that revenues and profits are growing rapidly. However, we believe that despite the increased risks associated with the credit crisis, the fundamentals of these firms are so strong that they will find necessary financing to continue rapid growth," said Adam Seitchik, chief investment officer for Trillium Asset Management, in a press release.

The tightening of credit could make capital hard to come by for clean tech startups. During the last quarter clean tech investment grew to a record $2.6 billion according to Earth2Tech, but clean tech startups such as Tesla Motors may find it harder to find investors during the coming months.
