Since cities act as the social and economic center of human society, more than half of population is gathered at cities to consume about 80% energy of the world. Therefore, reduction of greenhouse gas emission in cities has played an even more pivotal role worldwide in climate change. According to the case studies relating to the promoting program of low-carbon city, energy supply of city is one of key points to establish low-carbon city, and renewable energy technologies have to be developed to reduce dependence on fossil fuels in the situation of fossil fuel shortage. The objectives of this project is to collect and investigate recent international cases regarding the low-carbon city program on the topic of renewable energy in order to establish development roadmap and improvement suggestions, and then to review and develop our national strategies. The main works of this project are shown as following: 1.Establish the renewable energ consultating group for low-carbon and sustainable homeland program, committee members are organized from acdamic organizations, industrial trade unions, industrial circles, and government organizations. 2.Hold meeting for the renewable energ promoting and coordinating group for low-carbon and sustainable homeland program, committee members are organized from county and city governments. 3.Hold group meeting for the renewable energ consultating group and the renewable energ promoting and coordinating group to discuss the draft of low-carbon and sustainable homeland program. 4.Collect and investigare the renewable energ development roadmap of international countries, and porpose the enewable energ development roadmap in Taiwan. 5.Establish the control evalution and performance evaluation mechanism for the renewable energ project of low-carbon and sustainable homeland program. 6.Plan and structure the information system of renewable energ technologies for low-carbon and sustainable homeland program.
