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 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. Energy efficiency will be an even more crucial criterion for the global competitiveness and innovative power of industry in future years. Enhancing energy efficiency is therefore a key issue for industry.
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 third year for this Study, it tried to assess the energy efficiency and estimate the energy saving potential for manufacturing sectors, including Chemical and petrochemical, primary mental, Non-metallic minerals, food and tobacco, textile and leather, paper and printing, Wood and wood products, Transport equipment, machinery r.
2. Summary
The Korean manufacturing sector consumed 50% of the total supply of energy. This study describes the energy intensity trend in the Korean manufacturing sectors. The energy intensity of manufacturer was improved by the annual average of 3.4% for the period 2000–2010. In order to complement the limitation of the energy intensity, the decomposition analysis of manufacturing energy intensity in Korea, Japan, Germany, USA 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 energy-saving potential in 9 manufacturing sectors including Chemical and petrochemical, primary mental, Non-metallic minerals, food and tobacco, textile and leather, paper and printing, wood and wood products, transport equipment, machinery. The DEA model are applied to measure the energy efficiency performances of major OECD countries and the results obtained are presented.

Recommendation on policy
There is still substantial potential in Korea for saving energy and electricity. Significant proportion of the energy saving potential cannot be carried out in market due to various reasons. To leverage the substantial potential for saving energy and electricity, many measures are required that in the long run will reduce energy costs for business and consumers, contributing decisively to achieving our climate protection targets. A wide range of stimuli are still needed, including consumer information, product innovation and the commercialisation of energy-efficient products. Accordingly, the integrated, consistent policy should be promoted in terms of technique, economy and system. The government will consistently develop and promote the market for energy services. 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.
Economic incentives and improved information and advice are intended to help enable companies and private consumers to tap the hitherto unexploited potential for energy efficiency at their own initiative, thereby saving energy costs and relieving the strain on the environment. 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 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 in energy efficiency investments by developing 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 investment 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.
Governments have developed fewer policy measures targeted at small and medium-sized enterprises(SMEs) energy use than in the heavy industry sector, but conversely there is a greater energy management skills and capacity deficit in SMEs. The Government should consider developing and implementing a package of policies and measures to promote energy efficiency in SMEs. Korean government should continue improving the funding for low-interest loans and grants for efficiency measures in small and medium-sized businesses |
