An energy conservation management method includes selecting, by a policy server, a target scenario model from a plurality of scenario models based on a plurality of scenario attribute values of a target network, and configuring, by the policy server, a network device in the target network based on an energy conservation policy of the target scenario model. At least one of the plurality of scenario attribute values is an attribute value of a scenario attribute related to a network power consumption of the target network. The at least one of the plurality of scenario attribute values includes a plurality of attribute values of a corresponding scenario attribute, wherein each of the plurality of attribute values is collected at a different time from other attribute values of the plurality of attribute values that are collected at different times.
