Recently, the National Energy Administration announced the first batch of 55 "Internet +" smart energy (energy Internet) demonstration project. Including 12 cities integrated energy demonstration project of the Internet, 12 parks integrated energy Internet project. Cities and energy once again become the key words of our country's social and economic development.

The reason why we build cities or cities become the ultimate form of human aggregation lies in the fact that it is a platform for resources to converge and can greatly enhance human's core competitiveness - efficiency. But the problem is that as the city grows in size and complexity to meet our desire for greater efficiency, the efficiency of the city itself is declining. Some agencies predict that by 2045, 65% -70% of the world's population will live in cities. The world's megacities of more than 10 million people will increase from 28 in 2016 to 41 in 2030. This will undoubtedly exert unprecedented pressure on the city's transportation, food, water, sewage, public safety, and the most critical energy supply. In other words, in the face of a billion-dollar global population, our city will face a task that is almost impossible to accomplish.
