Abstract
The renewable energy is effective for preventing global warming, but it has some problems for its social introduction. We will first point out that symbiosis with society is the important aspect for the enterprise activity, and then we will be made clear by social investigation that the social introduction of new energy will be difficult unless it is based on symbiosis with society. We will propose a new concept of an enterprise model to solve the raised issues. Lastly we discuss the advantages of our proposed business model by regional community network, and by comparing with recently introduced new energy promotion law.
