ALBANY -— The eight-year-old campaign to make the state's offices, prisons, hospitals and dormitories more reliant on renewable energy is meeting with mixed success. Some agencies have been slow to meet targets for adopting wind, solar and other "green" power sources.

New York energy officials say they believe state agencies are now consuming 10 percent or more of their electricity from renewable sources — a target that was supposed to be met in 2005 under an executive order. But they are optimistic the state can meet the next target of 20 percent renewable consumption by 2010.

The concerted push for renewable power in state buildings dates to June 2001, when then-Gov. George Pataki signed a sweeping executive order setting a series of clean energy goals for state agencies.
