Each province or municipality in the Yangtze Delta Area has its own advantages in clean energy development，so only through mutual cooperation can the related effects be maximized. Especially for Shanghai，whose space is quite limited and which is short of clean energy resources，local energy structure is very difficult to improve without the Yangtze Delta clean energy cooperation. The neighboring provinces enjoy abundant clean energy resources，while Shanghai is short of such resources but boasts of clean energy innovation clusters of strong capability and technology trading platforms of strong radiation power；such complementarity lays down great foundation for the Yangtze Delta clean energy cooperation. In addition，some related hardware infrastructure such as interlinked electricity grids and natural gas pipelines，and some software infrastructure such as governmental cooperation platforms and market-oriented trading platforms have been in place. Shanghai should firstly take good advantage of related platforms，e.g. make best use of the Green Technologies Bank，and secondly should build clean energy facilities fitting Shanghai needs in the neighboring provinces through targeted investment or technology support.
