This article analyzes causal relationships among gross domestic product(GDP), electricity consumption, carbon dioxide($CO_2$) emission and foreign direct investments(FDI) inflow of Korea over the period from 1976 to 2014, using unit root test, cointegration test, and vector error correction model(VECM). As the results, this article found (1) a long-run bi-directional causality between GDP and electricity consumption, which may imply a negative impact of electricity consumption-saving policy on economic growth, (2) uni-directional short- and long-run causalities running from $CO_2$ emission to GDP, and a uni-directional long-run causality running from $CO_2$ emission to electricity consumption, which can result in a negative impact of $CO_2$ emission reduction policy on economic growth and electricity consumption, (3) a uni-directional long-run causality running from FDI to GDP, and uni-directional short- and long-run causalities running from FDI to electricity consumption, which may result from relatively lower electricity prices than investing countries, (4) no causality between FDI and $CO_2$ emission, which is based on the characteristics of FDI composed of service industries. Considering the above causal relationships among the four variables, the policy implication needs to focus on the electricity demand management based on the relevant R&Ds, and on the gradual transition from fossil fuel- to renewable-energy. Adaptive policy to increase the FDI inflow is also needed.

S&T policy has been traditionally regarded as a sector policy; however, it is now evolving into an infrastructure innovation policy that forms the foundation of diverse types of policies. Simultaneously, environmental and energy policies formerly considered as sector policies are now being expanded and integrated into a higher level policy for sustainable development. With these changes underway, the importance of policy integration has increased. Efforts are being made to minimize contradictions between environmental, social, and innovation policies that emphasize proactive linkage among policies or place the highest priority on environmental policy following the theory of Environmental Policy Integration (EPI). Confronted with these policy changes, the Lee Myung-bak government announced "Low-Carbon Green Growth" in 2008 as national agenda for development that focus attention on environmental and energy issues. Economic policy and environmental policy have been traditionally seen in a conflicting relationship with different paths of policy development. However, the administration of President Lee is now emphasizing the synergy effects between the environment and economic growth with the concept of green growth. The green growth policy of the Korean government has great significance as it has built a momentum for incorporating social goals such as environmental values or sustainable development into economic growth-oriented policies; however, there remain many challenges due to the legacy of the development period that has dominated Korean society. The Korean government says it reflects "EPI" or "environmentalism" in policy goals; however, in reality it prioritizes development over the environment.

In this study, Austrian cleaner production program, ECOPROFIT, was introduced to 15 companies in Korea. The performance and the proposed options of the program were compared with those of Austria. Various options such as good housekeeping, process changes, internal/external recycling, substitution of raw materials were suggested for domestic companies. There are something in common between Korea and Austria such as no relation between company sizes and derived options and good housekeeping as a major option. The difference is that 1.9 years of recovery period on investment is required in Korea, while only 0.5 year is required in Austria. The reason for not applying the suggestions was due to the priority of the company policies in Korea, but was due to the technical problems in Austria. To activate the cleaner production in the Korean regional industry, more systematic analysis on the examples and performances as well as additional studies to disseminate informations and the best practices are necessary.

Electricity is a basis for human existence. This paper attempts to analyze the households' willingness to pay (WTP) for the residential electricity use. The WTP for the residential electricity use can be defined as the sum of actual price of and additional WTP for it. The former is easily observed in the market, but the second is not observed and thus should be obtained through a WTP survey of households. To this end, this study conducted a survey of randomly selected 1,000 households in Korea in November 2010. The results indicate that the mean additional WTP for the residential electricity use was estimated to be KRW 11.24 per kWh. Given that the average price of residential electricity was KRW 98.07 per kWh at the time of the survey, the economic benefit from the residential electricity use was computed as KRW 109.31 per kWh. This information can be compared with the cost involved in the supply of one kWh of residential electricity.

This paper attempts to estimate the demand function for the transport LPG and to analyze long-run and short-run price and income elasticities. In addition, the paper measures consumer surplus and economic value ensuing from the transport LPG consumption by utilizing the estimated long-run price elasticity. The price and the income data are the monthly real transport LPG price and the monthly composite index adjusted by real transport LPG price from 2003 to 2012. Unit root test, co-integration test and error correction model are to take the procedure of estimation of demand curve. The demand for transport LPG is considered to be inelastic and the long-run demand is more elasticity than that of short-run. Price elasticity of demand estimate here is -0.422, and the estimated consumer surplus and economic value in 2010/03 are 966 and 1,781 billion won, respectively.

In general, reliability of AHP depends on pairwise comparison of evaluators. In addition, human judgment on the importance of alternatives or criteria is always imprecise and vague. The Fuzzy AHP technique is suggested and used widely recently. In this paper, we prioritize future energy technology development for well focused R&D. We selected 3 criteria and 10 sub-criteria. According to the result in this study, the most important sub-criterion is the precedence over other competitive technology, the second is the possibility for fundamental technology acquisition, and the third is the improvement energy efficiency. The other side, the lowest important sub-criterion is the technology level compared with advanced countries.

Recently, global economy has recovered and aspects of the renewable energy industry in the global competition is more fierce, the new growth engines of the major countries, including the United States and China, industry promotion policy as being deployed. Major advanced countries and Korea also invested a lot of money to wind power development as a part of renewable energy development and promoting the construction of wind power generation. The global wind power generation market is expected to further increase the scale to about 70 billion US dollars, thus, Korea as well as the installation of domestic wind power overseas actively considering. This study uses input-output analysis to estimate the role of wind power generation sector exports national economy. More specifically, this study shows what national economy effect of production-inducing effect, value-added inducing effect, and employment-inducing effect are explored with demand-driven moel. After define wind power generation sector what small sized of Input-Output table 168 sectors among 11 sectors, this study pays particular and close attention to wind power generation sector by taking the sector as exogenous specification and then investigating economic impacts of it. The wind power generation exportation case of overseas 100 billion won, production-inducing effect, value-added inducing effect, and employment-inducing effect are 205 billion won, 68 billion won and 1,054 persons, respectively. These quantitative information can be usefully utilized in the policy-making for the industrialization of wind power generation exports.

Combustible waste into energy policy is an effective method to respond to climate change and depletion of fossil fuels. Combustible waste into energy is the process of generating energy in the form of electricity and/or heat from the combustible waste such as vinyl, paper and plastic. This study tries to estimate the external benefit of enhancing the ratio of combustible waste into energy to primary energy from 1.89% to 5% using contingent valuation(CV) method. To this end, we report the results from a CV survey to elicit the willingness to pay (WTP) for combustible waste into energy. A CV survey of 500 households was conducted in the Seoul by using person-to-person interviews. Thus, the procedures of applying and the findings from the one-and-one-half bounded dichotomous choice spike model used to deal with the zero WTP responses are provided in the paper. The results show that the average WTP is estimated to be 2,724 won per household per month and statistically significant at the 5% level. Expanding the value to the Seoul gives us an aggregate value of 13.7 billion won per year.
