Apparently turbine ventilators can reduce attic temps pretty dramatically, which in turn can passively reduce cooling costs by 15%.

There are multiple methods because they work better in some places and not others. Where I live older houses frequently have turbine ventilators and newer roofs have something closer to the earthship style low intake with open vents at the peaks to accomplish the same thing but without the need for maintaining the lubrication.
