Abstract: Eastern coastal areas of China have been developed rapidly since the implementation of reform and opening policy.However,with the high-rapid development of economy,energy con-sumption in this area increased greatly.The energy structure,basing on coal,has resulted in seri-ous ecological and environmental problems.Exploiting renewable energy resources and introduc-ing Renewable Portfolio Standard(RPS)are the important approaches to optimize the energy structure of Eastern China and realize sustainable utilization of energy.The present paper,ac-cord ing to the international experience of executing RPS in other countries and conditions of ex-ploiting renewable energy resources in China,distinguishes broad sense(including large-and medium-scale hydro power)from narrow sense (not including large-and medium-scale hydro power)and quantitatively an alyzes the quota.The research shows:(1)The narrow-sensed renewable en-ergy quota is5.1%and broad-sensed renewable energy quota is18.4%.(2)Western China con-tributes90.2%to balance the whole country's renewable energy resources if not including large-and medium-scale hydropower.Including large-and medium-scale hydropower,the figure is63.8%.Exploiting small hydropower is more important to Western China.(3)Power corporations of East-ern China accomplish quota not only by buying Tradable Green Certificate(TGC),but also by ex-ploiting renewable energy resources in Western China.Implementing RPS is the gradual process of reasonably utilizing renewable energy re sources and reducing the cost.The execution of RPS attains the destination of sharing the benefits and taking on the responsibilities between Eastern China and Western China.
