论文摘要
全球能源部门的脱碳工作取决于能源生产的技术选择和印度等新兴市场的最终用途，在这些新兴市场中，预计空调将成为电力需求增长的主要驱动力。在这里，我们使用综合需求供应框架来量化需求增长和时间模式对长期电力系统演变的影响。在预计的可再生能源和锂离子储存成本下，我们的供求建模点要贡献了可再生能源的基本贡献（46-67％），以满足印度的年度电力需求到2030年。但是，如果没有适当的政策措施，即使现有的煤炭产生现有的煤炭产生，甚至可以快速地采用可再生能源的能量和诸如更高的能源效率，或者诸如高低的能源效率，或者促进了较低的能源，或者是较低的能源，或者，这些能量效率或诸如较低的技术范围内，或者是促进了较低的能源，或者是促进了较低的能源，或者是促进了较低的能源，或者是促进了较低的能源，或者是较低的能源效率，或者是较低的能源效率。分配水平的存储不足以减少2050年对2020年的年CO2排放，因为在此期间，预计电力需求的增长率相对较高。
Global energy sector decarbonization efforts are contingent on technology choices for energy production and end-use in emerging markets such as India, where air conditioning is expected to be a major driver for electricity demand growth. Here, we use an integrated demand-supply framework to quantify the impacts of demand growth and temporal patterns on long-term electricity system evolution. Under projected renewables and Li-ion storage cost declines, our supply-demand modeling points to renewables contributing substantially (46-67%) to meet annual electricity demand in India by 2030. However, without appropriate policy measures to phase out existing coal generation, even such rapid adoption of renewable energy coupled with one or more technological levers such as low-cost energy storage and demand-side measures such as setting aggressive AC efficiency standards and deploying distribution level storage, are insufficient to reduce annual CO2 emissions in 2050 vs. 2020 because of the relatively higher growth rate of projected electricity demand over this period.
