永續發展與綠能政策是目前全球共同的發展目標。其中，再生能源更是綠能政策中相當核心的一環。德國過去即以再生能源發展的成熟聞名於世，在多種再生能源的科技上領先全球。德國從1980年代起開始發展再生能源，綠黨也隨後因應社會力量的成熟而誕生，並且在之後的能源議題上扮演推手。1990年開始陸續有配套法規的制訂，2000年正式通過再生能源法，迄今再生能源發展迅速而成熟。從德國看再生能源的進步有幾個意涵，包括永續發展、經濟與安全、以及市民社會的成熟等。此外，在歐盟多層級治理的概念下，德國與歐洲如何共同推動再生能源之發展，也對區域共同治理的概念提供觀察的對象。本文針對德國再生能源發展的歷程與近況做討論，從政策面認識德國再生能源的推動，以及歐盟對再生能源發展的現況，結論再提出對台灣發展再生能源的些許省思。

With the rising awareness of environmental protection, renewable energy has become a much discussed issue in the making of government policy. Germany, among European Union member states, has written many successful stories in the development of renewable energy and technology. Starting from the 1980s, German government has dedicated to restructure the country's energy sources and to strengthen environmental protection consciousness of its citizens. Owing to such increasing concerns on energy issues, the Green Party came to power and gradually dominated the implementation of sustainable energy policies in the 1990s. In 2000, the Renewable Energy Sources Act (Erneuerbare-Energien-Gesetz, EEG) was passed, which has formulated a complete legal system for sustainable energy. This paper concerns on the development of renewable energy policies and strategies in Germany, for they provides a rich source for studying sustainable development, national energy security, and the participation of civil society. In addition, Germany's experience of working with EU to regulate renewable energy policies also helps us to understand regional public management in EU. More importantly, using Germany as an example, this paper intends to shed some light on Taiwan’s planning of renewable energy policies.
