I. Introduction
Since human beings have reached a consensus on green and low carbon energy consumption, currently many countries, especially the advanced countries are trying to reduce carbon emission and improve energy efficiency. It is the energy Internet (EI) that is regarded as the most effective approach to realizing such target. Rifkin analyzed the prospect of EI in The Third Industrial Revolution [1], where EI is supposed to bring people with new ideas, such as green energy, low carbon, high efficiency and energy sharing.
