Two departments: Actively promote the development of biomass, solar thermal, and ocean energy for power generation.

The National Development and Reform Commission and the National Energy Administration issued the "15th Five-Year Plan for the Development of Renewable Energy", which mentions the vigorous promotion of transformation and upgrading of biomass power generation. It is advocated to promote the increase in heating value of biomass power generation according to local conditions. Encouragement is given to the integrated development of biomass power plants with wind power, photovoltaics, and actively explore the application of biomass power generation in new formats such as direct connection of green electricity. Actively promote the large-scale development of solar thermal power generation. Reasonable configuration of solar thermal power generation in large wind power and photovoltaic bases. Construct a number of locally absorbed large-capacity solar thermal power stations in Qinghai, Xinjiang, Gansu, Inner Mongolia, Tibet and other regions. Promote the coordinated layout of solar thermal power generation and industries, and explore new formats such as direct connection of green electricity based on solar thermal power generation as the primary power source. Explore the construction of small-scale solar thermal power generation systems according to local conditions. By 2030, the national installed capacity of solar thermal power generation strives to reach 15 million kilowatts. Accelerate the scale development and utilization of marine energy. Promote the scale utilization of tidal energy, wave energy, temperature difference energy and other marine energy according to local conditions, and continuously expand engineering pilot projects. Promote the complementary development of multiple marine energies and guide the integration of marine energy with related marine engineering. By 2030, the national installed capacity of marine energy strives to reach 400,000 kilowatts.
