摘要
為了對抗氣候變遷,臺灣政府於2022年公布《臺灣2050淨零排放路徑及策略總說明》,提供落 實長期減碳目標之初步藍圖,以接軌國際邁向淨零排放轉型。在此背景之下,能源供需勢必將出現 巨大的變化;了解能源流對於減少碳足跡至關重要。本研究基於2020年臺灣能源平衡表等數據,以 桑基圖繪製出我國的能源流現況,並針對能源的三個主要階段─初級能源、電力轉換、終端消費─ 進行全面性的分析及評估。此外,本研究探討了2050淨零政策下的潛在能源流影響,並重點關注電 力部門去碳化與運輸部門電力化的影響。至2050年,電力部門的發電結構將由化石燃料轉變為再生 能源為主的系統;公路運輸部門的電力消費將因運具電動化的政策增加至近18%。藉由將臺灣能源 的供需情形以視覺化的方式呈現,以協助利益相關方瞭解我國能源系統各階段之使用、轉換、平衡 與損耗之情形。本研究建構的能源流桑基圖成果可作為臺灣永續發展與能源管理的參考基準,具有 高度學術研究及實務應用之價值。

To fight against climate change, Taiwan has recently published “Taiwan’s Pathway to Net-Zero Emissions in 2050”, which provided practical action plans for achieving the long-term reduction targets. Great impacts are anticipated during the transition toward a net-zero future. Understanding energy flows from resources to end users is essential for reducing the carbon footprint. Therefore, this study traces the energy flows throughout Taiwan’s economy in 2020 using Sankey diagrams, mainly based on the Energy Balance Sheet. Three main energy stages are identified and well examined: primary energy supply, energy transformation, and energy consumption. Moreover, this study explores the potential energy flow impacts of the 2050 net-zero policy, focusing on the impacts of decarbonizing electricity generation and electrifying on-road vehicles. From now to 2050, the power sector will gradually shift to renewable-dominated systems, and the electricity consumption in the road transport sector will increase to nearly 18%. The Sankey diagrams of energy flow established in this paper serve as a valuable tool in sustainable development and energy management, contributing academic and practical insights to the ongoing net-zero transition.
