本文根据几十年系统研究，提出与工业4.0相适应的能源4.0概念，其特征是通过互联网与电网，将太阳能、风能、化石能源、核能等供电侧与电解铝、氯碱、大规模海水淡化、制氢、煤炭清洁化、煤化工、冶金等高耗能产业用电侧，构建一个有机的高效、低成本、可持续、可调控的网络，即构建我国产业能源互联网体系，重塑经济结构，实现经济优化升级、成为实现经济新常态的重要抓手。

The concept of energy 4.0， which adapts to industry 4.0 is proposed in this work. Its main feature is that it combines the wind energy， solar energy， nuclear energy and other fossil energies which are energy providers with the high-energy-consuming industries such as electrolytic aluminum， chlorine alkali， large-scale desalination of sea water， hydrogen， clean coal， coal chemical and metallurgy industries by the internet of things. This energy & industry internet is a high efficiency， low cost， sustainable， and regulatory network. energy 4.0 will play an important role in industry upgrading and economic restructuring.
