The Obama administration has ordered an independent review of loans made by the Energy Department to energy companies – a clear response to the controversial and now-bankrupt Solyndra Inc. solar energy company.

It’s the latest step in the face of growing criticism over the $528 million government loan to Solyndra, which was part of the administration’s economic stimulus package meant to advance green energy. Last month, FBI agents and investigators from the Department of Energy’s Office of Inspector General searched Solyndra headquarters in California for documents and other information.
