Under the goal of “Carbon Emission Peak and Carbon Neutralization”, the integrated development between various industries and renewable energy (photovoltaic, wind power) is of great significance in China. This paper summarizes the relevant policies, integration schemes and typical cases of the integrated development between renewable energy and other industries. First, the development status of wind and solar generation in China is introduced. Second, we summarize the relevant policies issued by the National Development and Reform Commission, National Energy Administration and other departments to promote the integrated development in photovoltaic and wind power generation in China. Third, eight kinds of photovoltaic three-dimensional development models are described, including “photovoltaic + agriculture, industry, environmental protection, transportation, architecture, communication, hydrogen and ecology”. Fourth, eight kinds of wind power three-dimensional development models are summarized, including “Offshore wind power + marine ranch, marine energy, marine tourism, marine oil and gas, hydrogen, communication, Energy Island” and “Onshore wind power + courtyard”. In the future, the promotion and application of the above integrated development projects will be accelerated. This overview aims to provide reference for the design in photovoltaic and wind energy systems and help potential investors to make decisions.Renewable energySolar PVWind powerPoliciesEnergy is the necessary guarantee for human production and maintenance of life. Since the first industrial revolution, human beings have continuously increased the development and utilization of energy in order to meet the growing needs of life. Since the 21st century, the global energy security and ecological environment protection issues have become increasingly serious. The COVID-19 epidemic has seriously affected the economic and social development of countries. The release of the Sixth IPCC Assessment Report “Special Report on Global Warming of 1.5 °C” in October 2018 means that the global energy structure is facing a transition. By 2050, 70%–85% of global electricity supply needs to come from renewable energy sources in order to reduce industrial carbon dioxide emissions by over 75% compared to 2010 and control temperature rise within 1.5 °C. To address climate change to economic recovery and long-term goals together, countries have a “green recovery” route choice, placing green economy at the core of the stimulus package, and more than 50 countries have formulated policies and regulations for renewable energy development (Oosthuizen and Inglesi-Lotz, 2022).In recent years, China's position in the field of renewable energy has become increasingly prominent, gradually becoming the leading role in promoting the transformation of global energy structure. As the “largest country in renewabl. During the 12th Five Year Plan for Economic and Social Development of the People's Republic of China (12th Five-Year Plan) period, the combined annual power generation of wind and photovoltaic (PV) power in China accounted for less than 4%, annual growth of about 0.6% (Fig. 1).During the 13th Five-Year Plan period, China's energy structure continued to be optimized, and remarkable achievements were made in low-carbon transformation. The proportion of non-fossil energy consumption reached 15.9%, while the proportion of coal consumption dropped to 56.8%. The installed capacity of non-fossil energy power generation ranked first in the world, with the installed capacity of wind and solar power generation reaching 280 GW (kW) and 250 GW respectively (National Development and Reform Commission, 2022a). The maximum single capacity of onshore and offshore wind power continues to increase, the diameter of wind turbines continues to grow, and breakthroughs in key core technologies continue to be made. Photovoltaic power generation in efficiency, capacity, technical level and other aspects continue to maintain an international leading position (China Electricity Council, 2021). During the 13th Five-Year Plan period, China's wind & PV annual power generation accounted for 5%–10%; and growing at about 1 percentage point per year.Innovation and integration is the key direction for the future development of renewable energy power stations. The first is the integration between power stations and development sites, the second is the technical integration between energy development and utilization, and the third is the integration of industrial development (Ye, 2021). Countries around the world continue to deepen the layout of PV power industry chain innovation, as a major strategic measure to promote the development of emerging industries. Photovoltaic applications are developing towards multi-use scenarios. Countries around the world, according to their own actual conditions, actively promote the development of PV building integration, floating PV, PV agriculture, PV carport and other new application forms.For example, the United States encourages rooftop PV through tax incentives, loan guarantees and other policies (Borenstein, 2017; Leibowicz et al., 2019; Wolske, 2020). In terms of solving the consumption problem, the United States encourages residents to use their own electricity spontaneously. When residents install PV power equipment in their homes, if there is still surplus electricity after deducting electricity consumption, they can transfer the electricity to the next month for self-use. Encouraged by such a self-use policy, the problem of grid connection consumption has been solved, and the cost of l.
