台灣鋼鐵業能源效率與能源轉型分析
Analysis of Energy Efficiency and Energy Transition in Taiwan's Steel Industry
摘要
鋼鐵行業屬於能源密集產業之一，對全球能源消費與碳排放的占比極高，我國鋼鐵業能源消費占工業部門15.7%，僅次於化材業與電子業，如何降低鋼鐵生產的能源消費與碳排放已為當前重要的課題。因此我國政府於2013年制定鋼鐵業能源效率規定與2015年實施強制性節電1%的政策，促使產業推動各項節能措施來提升能源效率，鋼鐵產業能源密集度與節能量均逐年提升，政府之節能政策已顯成效。而國際能源署（IEA）也提出能源密集產業應如何朝向能源轉型之方向，來達到長期的節能減碳目標，我國鋼鐵業在能源轉過程中也發揮了重要貢獻。本文目的為分析鋼鐵產業之產銷與能源效率趨勢，說明我國鋼鐵業在推動節能減碳之努力與成效，並比較國際鋼鐵行業的能源轉型策略與國內鋼鐵業之作法，最後提出我國鋼鐵行業的能源轉型建議方向，以作為鋼鐵業節能減碳之決策參考。

The steel industry is one of the energy-intensive industries, accounting for a very high proportion of global energy consumption and carbon emissions. Taiwan's steel industry energy consumption accounts for 15.7% of the industrial sector, second only to the chemical industry and the electronics industry, how to reduce energy consumption and carbon emissions in steel production have been an important issue today. Therefore, the government formulated the energy efficiency regulations for the steel industry in 2013 and implemented the mandatory energy-saving 1% policy in 2015, forcing the industries to carry out energy-saving measures to improve their energy efficiency. The energy efficiency of the steel industry has been increasing year by year, and the government's energy conservation policy has been effective. The International Energy Agency (IEA) also proposed energy transition in energy-intensive industries to achieve long-term energy-saving and carbon reduction targets. Taiwan's steel industry has also played an important role in this energy transition. The purpose of this paper is to analyze the production and energy efficiency trends of the steel industry, explain the efforts and achievements of the domestic steel industry in promoting energy conservation and carbon reduction, compare the energy transformation strategies of the international steel industry with the domestic steel industry, and finally propose the energy of the domestic steel industry.
