Though traditional global energy security risks have lowered,there is a pressing need for cooperation in the governance of global energy,particularly for energy investment security and environmental security.Increasingly apparent defects,inefficient reaction between mechanisms,and new challenges show that the nation-centered model should transfer to a more complex multi-level governance structure.The current governance mechanism for energy must absorb more newly rising countries,include more non-state actors,strengthen financial instruments,and perfect legal structures to achieve a fair,effective international energy governance order.
