Energy Internet integrates small-scale renewable energy systems, electric loads, storage devices, and electric vehicles for effective transaction of power backed by emerging technologies such as Internet of Things, vehicle-to-grid, and blockchain. Energy Internet, a futuristic evolution of electricity system, is conceptualized as an energy sharing network. Its features, such as plug-and-play mechanism, real-time bidirectional flow of energy, information, and money can lead to significant benefits and innovation in electricity. Extensive electrification based on renewable energy sources is seen as one of the most potential growth options to tackle these issues in the medium to long term. We revisit some attempts to design a digital grid similar to the internet, including packetized management of specific loads (electric vehicles. Digital technologies have direct and indirect effects on energy use and emissions, with data centres connected to electricity grids with lower shares of generation based on fossil fuel producing less associated emissions, and hold enormous potential to help (or hinder) global clean energy. The challenge of building the Smart Grid has just become a bit easier, thanks to a set of standards approved by the Smart Grid Interoperability Panel (SGIP). This set of standards, embodied in a document titled " Internet Protocols for the Smart Grid Although most users and consumers know very.
