In a rare public appearance since leaving office, former Republican California Gov. Arnold Schwarzenegger called the debate over bankrupt solar panel maker Solyndra narrow-minded in a world moving ever-faster toward renewable energy.

Schwarzenegger said Thursday he took time out from a movie shoot to address Gov. Jerry Brown's climate conference at the California Academy of Sciences.

While in office, the former governor frequently promoted California's landmark 2006 global warming law, called AB32, which paved the way for the state's cap-and-trade system for controlling greenhouse gas emissions by the worst polluters.

Schwarzenegger said the Fremont, Calif.-based solar panel maker that went under despite a half-billion dollar government loan did the best it could but made business mistakes that led to its demise.
