By collecting the research results released by relevant statistical departments and authoritative institutions, this paper summarizes the international energy development situation, systematically combs the energy development situation of the European Union, United States, Australia, India, Brazil. The development trend of wind, solar, biomass, geothermal, ocean, and hydrogen energy have been analyzed. In addition, this paper proposes that China should draw up its own development path of renewable energy from international development experience, and actively explore renewable energy policies and strategies adapted to different stages of development.
