California urged to assess energy reform California officials need to add up the costs of all the state's clean-energy policies before adopting any more, according to a report issued Monday by a government oversight agency. The state has adopted a series of far-reaching energy reforms - boosting the use of renewable power and reining in greenhouse gases - without considering how each policy affects the others, the Little Hoover Commission argues in the report. Should energy costs unexpectedly escalate or energy becomes unreliable, California will jeopardize not only its own environmental stewardship goals, it will put the state's economy at risk and jeopardize support for renewable energy in other states and other countries as well. Construction of more fossil fuel plants, triggered by the rising use of renewable power, could complicate the state's efforts to curb greenhouse gases, the report says. The report's authors call on Gov. Jerry Brown to issue an executive order to the Energy Commission and the Public Utilities Commission, launching a study of the state's energy policies and regulatory structure.
