Brown declined to comment on the recent legislation that would have required California's utilities to get a third of their power from renewable sources but limited the amount they could import from out of state. Gov. Arnold Schwarzenegger has said he will veto the bills in part because of that restriction.

On Tuesday, he signed an executive order establishing the 33 percent mandate with fewer restrictions than were included in the bills, which were pushed by majority Democrats. Utilities will have to meet the goal by 2020.

Brown declined to comment on the legislation because he hadn't read the entire bill but said he supports getting renewable energy from California and from wind, solar and geothermal producers in other states.

Campbell, a former Schwarzenegger finance director, said he also agreed with the governor's decision to veto the renewable energy bills.

Four of the five leading candidates for governor were attending a forum on such issues as energy, education, transportation, taxes and infrastructure sponsored by the Silicon Valley Leadership Group. The group said its goal was to bring together business, nonprofit and civic leaders to discuss how to make California more competitive.
