In China, based on the experience of demonstration projects, the DES is now being commercialized. Under the new opportunity of energy production and consumption promoted by the national ＂Internet Plus＂ action plan, the development of the DES was reviewed in this paper; four categories of market demand and five key issues for DES deployment were analyzed; five types of potential DES users and five key points of technical path implementation proposed based on many years of engineering practices and hundreds of project case studies were proposed. 4E elements should be used to evaluate and choose the project and lead the innovation model of DES by energy production and consumption revolution with the sustainable development of the Intemet plus DES. The future innovation models include intelligent energy modularity and menu-type services with the demands of the client side, and the kind of new thinking for DES services that ＂you are in charge of your own energy production and consumption, while we are also at service when needed for installation and maintenance.＂ The aim of innovation mode is to give the energy sovereign back to the people, and form a perfect Intemet plus DES ecosystem.展开更多
