The main opportunities include: the overall green transformation and upgrading of the economy, the formation of a high-quality green industrial economic system driven by innovation and oriented by green and low carbon, and the rapid development of terminal energy utilization electrification technology in renewable energy utilization technology, industry, construction, transportation and other fields. The challenge is that China's energy endowment is rich in coal and poor in oil and gas. In the short and medium term, the power supply structure will still be dominated by coal, which is difficult to transform. The key core technologies of decarbonization in transportation, industry and construction still need to be broken through.
