In order to ensure energy security, China should make full use of existing resources, such as the open space on highways, highways and railways, the roofs of industrial and mining areas, towns and villages, and the large-scale clustering of deserts, gobi, wastelands and grasslands to vigorously develop new energy such as photovoltaic power and wind power. At the same time, large-scale construction of pumping and solar thermal energy storage power stations on the mountains of various provinces, cities and counties in China will adjust and balance China’s large power grid, To achieve the goal of reducing carbon without reducing productivity, this paper also analyzes and demonstrates its feasibility from the perspective of comprehensive social benefits and investment, and proposes that large-scale cluster construction of wind and electricity in offshore waters should no longer be carried out globally.
