The purpose of this paper is clarified how planning system can work for the use of renewable energy sources in England. The paper firstly reviews the new planning system, followed by the analysis of renewable energy strategies developed by nine regional assemblies. From the analysis, the size of the development and proportion of renewable energy are clearly decided in London, however, the policy is not highly identified by applicants. The understanding of renewable energy system is important to planners; therefore, guidance making and co-work mechanism between planning and energy sides are important.
