Research on the Development Characteristics of Green Energy Industry in Main Developed Countries

Green energy is regarded as the breakthrough of the fourth technological revolution of mankind, which is highly concerned by the whole world. By analysing the development strategies of major developed countries to promote green energy industry, this paper constructs a theoretical framework from four aspects: government policy, green consumption, technology and capital, so as to summarize the typical characteristics of the development of green energy industry. The study found that government policy and technology are the main driving force for the development of green energy industry in major developed countries, the resource-rich United States leads the industrial development with policy, and the European Union obtains new energy development through policy and technological innovation at the same time. Japan continues to innovate and take the lead in technology to break the limitations of innate conditions. The conclusions of the study will help countries with the same resource base, policy environment and consumption concept to sort out the development ideas of green energy, and provide some reference and reference for the formulation of effective development strategies
