In just a year, a little-noticed state panel created with bipartisan legislative support worked briskly to authorize $104 million in tax breaks to help "green" companies in California buy equipment and add jobs.

But the program was halted last month following the bankruptcy of Solyndra, a Fremont solar company that received $25 million in state tax breaks and, more notoriously, a $528 million federal loan guarantee despite its precarious financial state. The Solyndra debacle is being investigated by Congress.
