摘要 | 1. Research Background and Purpose With the appearance of energy price increasing, energy resource scarcity, security of energy and sustainable development problem, the government is gradually concerned about measuring and improving energy efficiency to save energy in many large energy consumption countries. As the low-carbon green growth emerges recently as a national issue in the face of energy resource and environmental crisis, the improvement of energy efficiency has been promoting as a key issue in the governmental policy not as selection but as required item. The energy efficiency is very important in terms of energy security, climate change and economy. Unless the active response in the national level to the enhancement of energy efficiency is performed, the nation would suffer from not only the relative deterioration in the domestic economic, social welfare, but also the decline in the industry and national competitiveness in the future. This Study purposes to assess the energy efficiency and to analyze the energy saving potential by manufacturing sector over 3 years (2010~2012) centering on manufacturers. This year, the second year for this Study, it tried to assess the energy efficiency and estimate the energy saving potential for manufacturing sectors, including food and tobacco, textile and leather, paper and printing, Wood and wood products, Transport equipment, machinery and fabricated metal products 2. Summary The Korean manufacturing sector consumed 50% of the total supply of energy. This study describes the energy intensity development in the Korean manufacturing sectors between 2000 and 2010. The energy intensity of manufacturer was improved by the annual average of 3.3% for the period 2000–2010. In order to complement the limitation of the energy intensity, the decomposition analysis of energy intensity was performed in order to separate structural and intensity effects through Log Mean Divisia method. It was found that the aggregate energy intensity in the manufacturing sector was highly dependent on the changes in the energy intensive sectors(EISs). The trend is to produce more while consuming less energy. In Korea, structural and intensity effects contributed to energy efficiency improvement. and Structural effects dominated over intensity effects. This study approaches the measurement of energy efficiency from a production theoretic framework and uses Data Envelopment Analysis(DEA) to measure energy efficiency in the manufacturing sectors. DEA has recently become a popular method in measuring energy efficiency. This study measured energy efficiency and investigated the maximum energy-saving potential in 6 manufacturing sectors including food and tobacco, textile and leather, paper and printing, wood and wood products, transport equipment, machinery and fabricated metal products. The DEA model are applied to measure the energy efficiency performances of major OECD countries and the results obtained are presented. 3. Recommendation on policy Significant proportion of the energy saving potential cannot be carried out in market due to various reasons. Accordingly, the integrated, consistent policy should be promoted in terms of technique, economy and system. And the promotion should continue to be improved through monitoring and assessment on overall energy efficiency policy. In addition, the overall energy efficiency including technique innovation and industrial restructuring are required. The government should identify the appropriate objective after analyzing technique level, energy saving capability and the competitiveness by sector and industry. The government should remove the market barriers to interfere with the adoption and expansion of high-efficiency and best practice. Especially, the The government should actively introduce the win-win cooperation among large and medium-sized firms and drive the implementation of energy audit result through funding the energy saving facility according to the energy audit. In addition, after grasping the cost-effective, energy reduction-possible sector at plant and facility unit, the government needs to support them so that the energy management can be expanded across the overall industry. Above all, the intimate partnership between the government and companies are needed to carry out the energy saving and the greenhouse gas reduction. The Government should facilitate private sector��s involvement in energy efficiency investments by adopting and publicise to the private sector, a common energy efficiency saving verification and measurement protocol, to reduce existing uncertainties in quantifying the benefits of energy efficiency investments and stimulate increased private sector involvement and encouraging financial institutions to train their staff and develop evaluation criteria and financial tools for energy efficiency projects. Governments should collaborate with the private financial sector to establish public-private tools to facilitate energy efficiency financing. The Government should consider developing and implementing a package of policies and measures to promote energy efficiency in small and medium-sized enterprises(SMEs). Governments have developed fewer policy measures targeted at industrial SME energy use than in the heavy industry sector, but conversely there is a greater energy management skills and capacity deficit in SMEs. |
