The period of the fourteenth Five-Year Plan is critical for the growth of China's energy revolution. As an energy-rich region of China, Northwest China offers inherent advantages for the growth of the energy industry. China will be able to achieve its goals of carbon peaking and carbon neutrality due in great part to its energy development plans.The research begins by comparing the underlying conditions of energy development in Northwest China. The paper next evaluates the level of fossil and sustainable energy sector clustering in Northwest China, revealing that the challenges involved with developing fossil and sustainable energy are dissimilar. Using the problems as a guide and the "energy revolution" promotion requirements and energy base construction as a foundation, the development of fossil energy in Northwest China must lengthen the industrial chain to improve the added value of products, and promote the synergistic and complementary development of the energy industry cycle, fossil energy, and sustainable energy. Optimizing the power transmission structure, capitalizing on the national power market reform, and promoting international energy cooperation are vital for fostering a sustainable energy sector.
