Venture investments in cleantech have taken a nosedive after bringing in poor returns. But some argue the problem isn't in cleantech -- it's in the investment strategy. On this week's podcast, the Energy Gang will talk with Rob Day of Black Coral Capital about how the "next wave" of cleantech investment is bringing innovative and realistic opportunities for the industry.

Then we'll talk about what the coming closure of the Vermont Yankee nuclear power plant says about the state of nuclear power in the U.S., as well as the coming dark clouds for clean energy in Congress this fall.
