本文探讨了加速能源过渡到2050年的技术和经济特征，使用新的可再生能源数据集。分析表明，能源效率和可再生能源技术是这一过渡的核心要素，它们之间的协同作用同样重要。有利的经济、无处不在的资源、可扩展的技术和显著的社会经济效益支撑着这种转变。可再生能源可以提供全球能源总需求的三分之二，并有助于从现在到2050年将全球平均地表温度上升限制在2摄氏度以下所需的大部分温室气体减排。需要调整扶持性政策和监管框架，以调动可再生能源增长所需的六倍加速，风能和太阳能光伏技术的增长估计最高，并辅之以高水平的能源效率。然而，要确保最终消除二氧化碳排放，将需要新的技术和创新，特别是在运输和制造部门，这在国际辩论中仍然基本上被忽视。需要更多地关注新出现的基础设施问题，如充电基础设施和其他部门耦合影响。
This paper explores the technical and economic characteristics of an accelerated energy transition to 2050, using new datasets for renewable energy. The analysis indicates that energy efficiency and renewable energy technologies are the core elements of that transition, and their synergies are likewise important. Favourable economics, ubiquitous resources, scalable technology, and significant socio-economic benefits underpin such a transition. Renewable energy can supply two-thirds of the total global energy demand, and contribute to the bulk of the greenhouse gas emissions reduction that is needed between now and 2050 for limiting average global surface temperature increase below 2 degrees C. Enabling policy and regulatory frameworks will need to be adjusted to mobilise the six-fold acceleration of renewables growth that is needed, with the highest growth estimated for wind and solar PV technologies, complemented by a high level of energy efficiency. Still, to ensure the eventual elimination of carbon dioxide emissions will require new technology and innovation, notably for the transport and manufacturing sectors, which remain largely ignored in the international debate. More attention is needed for emerging infrastructure issues such as charging infrastructure and other sector coupling implications.
