The purpose of this study is to propose a way to develop and disseminate the renewable energy technologies and industries in the local community. Fundamentally, the renewable energy is able to reduce environmental pollution and diminish a use of fossil-fuel energy in the local area. And it will lead to promoting regional sustainable energy in the future, as well as making contributions to local economic development. Above all, based on the environmental conservation project, including greening of the city and improving water quality, Daegu metropolitan city has launched a series of renewable energy projects, such as solar city programs and local energy plan. But, some problems still exist, due to the technological, economic and socio-political barriers. Thus, to encourage and disseminate a renewable energy in Daegu city, we need to examine a present condition on renewable energy and analyze constraint elements to prevent its distribution. Based on the results, we have to set the feasible strategy to develop and disseminate renewable energy in Daegu city and help it systematically integrate renewable energy technologies and industries into environmental economics and city planning. Ultimately, to achieve this purpose, we need to adopt the following policy measures: (1) establishment of a master plan for renewable energy; (2) interconnection between local development project and energy industry; (3) promotion of technological development; (4) inducement of and assistance to renewable energy industry; (5) fostering venture companies; (6) specializing Daegu's public office by energy-specific education programs. In particular, local entities including local company, consumers, policy-makers and citizen's groups have to pay attention to local energy plan for the regional sustainable energy future. These measures will lead to establishing an environmentally friendly and sustainable city.

고유가와 기후변화로 인해 에너지 수요관리정책에 대한 관심이 국내외 적으로 높아지고 있다. 그렇지만 국내에서는 에너지 수요관리와 관련해서 지방정부의 역할이 미약하기만 한 실정이다. 에너지 수요관리정책과 관련해서는 기술력과 자금을 확보한 중앙정부의 역할이 중요하겠지만 직접적인 에너지 소비지에 밀착되어 있는 지방정부의 역할도 중요할 수 있다. 따라서 지방정부의 에너지 수요관리정책을 활성화시키고 5년마다 수립되는 '지역에너지계획'의 실행력을 높이기 위해서는 지역의 에너지 소비특성에 대한 정확한 이해에 기반한 계획의 수립이 필요하다. 이에 본 논문에서는 전국 16개 지자체의 에너지 소비를 인구, 생산, 원단위라는 항목으로 분해해서 그 특성을 분석하고자 한다. 지수분해분석 결과 광역시의 경우에는 외환위기 이후 생산 증가로 인한 에너지 소비 증가를 원단위 개선 효과로 일정 부분 상쇄시킨 것으로 나타났다. 반면에 도 지역의 경우에는 제조업 중심의 산업화로 인해 외환위기 이후에도 에너지 소비 증가를 상쇄시키지 못한 것으로 나타났다. 결론적으로 본 논문에서는 제조업 비중이 높은 도 지역의 경우 에너지 저소비형 산업구조로의 전환이 필요하며, 3차 산업 중심의 구조전환이 이루어진 광역시의 경우에는 건물, 수송 분야의 에너지 효율개선이 필요함을 제안할 수 있었다.

Most governments have an interest in unused energy, because of high oil price and climate change. Particularly, it is very important to urban governments which have less renewable energy than other local governments. So Seoul, the capital of Korea, established a plan for the development of unused energy in 2007. But it has some problems related to the feasibility of this plan. So this paper checked and reviewed the economic feasibility of unused energy development cases in four cities by using three sub elements: technology, infrastructure, institution. As a result, it discovered that these urban governments have technological feasibility because they are located near big river or ocean. And they used the existing infrastructure and received the institutional subsidies from central governments in order to increase the economic feasibility of unused energy development projects. In conclusion, local governments of Korea have to try to seek how they can utilize the existing infrastructure for unused energy development in the situation that there are few institutional supports from the central government.

Since the industrial revolution, the global environmental problems such as greenhouse gas accumulation and the average temperature increase have caused people's attention. 'Low Carbon, Green Growth' was presented to cope with these global concerns, as one of main policies of 2008 in Korea. The paradigm of a green urban development is started to concern the whole city's energy problems owing to realize 'Low Carbon, Green Growth' in the urban side. The government established a nation's basic energy plan for 20 years, and some local cities made efforts to develop new renewable energy such as the solar, wind and water energy which are suitable to each city's character. As a part of these efforts, the concept of U-Eco city is newly appeared to reflect upon ubiquitous technique, urban ecology and the next generation energy system. However, urban plan is difficult to adopt this next generation energy system with existing laws, regulations and technical systems. The new executive and systematic system is needed to realize the U-Eco city U-Eco for the management of an efficient city. In this study, the authors investigate the concept of the next generation energy system and U-Eco city to realize the energy-efficient city plan and analyze problems to occur during the application of them in an existing city plan. Then, the authors show the remedies to deal with occurred problems.

The Korean government enacted the "Special Law for Improving Air Quality of Metropolitan Area" in 2003. According to this plan, Korean government plan to lower the concentrations of $PM_{10}$ and $NO_x$ to $40{\mu}g/m^3$ and 22 ppb, respectively, by 2014. In this study, we analyze emission reduction strategies to lower their concentration. Emission reduction for the supply of mass energy and regenerative energy are compared with several scenarios. According to the results, 713 t/y of $NO_x$ and 165 t/y of $PM_{10}$ will be reduced by enhancing the number of households supplied by local heating and air conditioning. And also 5 t/y of $PM_{10}$ and 312 t/y of $NO_x$ will be reduced by replacing conventional energy with solar energy by 2014.

The objective of this study is to propose a color plan for rural villages that seeks harmony between natural and artificial environments in consideration of the fact that as new and renewable energy businesses increase drastically, problems of landscape color occur in rural areas. To this end, the current color conditions over the target regions are examined in context of energy businesses; a land simulation is developed; a survey on the preferences is conducted with the result analyzed; and finally, a color plan for villages where energy businesses and non-energy businesses are conducted. For the survey, 40 photos including simulation photos and original photos of villages were used: the photos before and after the simulation was applied were shown to village residents. The validity of the selected colors was then evaluated accordingly. The survey was conducted among 15 residents in villages where energy businesses were conducted and 15 in villages where non-energy businesses were conducted. As new and renewable energy methods such as solar energy panels are utilized over rural villages in the future, selecting artificial environmental colors that can better represent the region's identity and that are in harmony with natural environments will be an important factor in community center or housing remodeling projects, local community development projects, and so forth. It is expected that the present study can be utilized as the basis for village color plans that seek to consider actual local conditions based on objective data rather than selecting colors uniformly or based on subjective judgment.

T Recently, the government has been promoting the expansion and supply of renewable energy as an alternative for achieving carbon neutrality and the nationally determined contributions by 2030. In 2020, the Ministries of Industry and Environment and the Korea Forest Service collaborated to build a nationwide onshore wind energy siting atlas considering wind resources and forestry and environmental regulations focused on central regulations. In this study, the ordinances of the local governments were analyzed to examine the effects of regional location regulations on the expansion of onshore wind power energy generation facilities, in addition to those of central regulations. A development permit standard survey of 226 urban plan ordinances of the local governments nationwide showed that presently in 2022, 52 municipalities are applying regulations on wind energy generation facilities by ordinances. This is twice more than that in 2018, when renewable energy power generation facility development was difficult. Additionally, the location regulations applied by these ordinances were organized by items and regions, and regulatory characteristics, such as the number and scope, were analyzed by regions. To analyze the spatial distribution characteristics, JeollaNamdo was selected as the case area. A spatial DB was established for regulated areas based on the regional and central regulations, and the spatial distribution characteristics and the regulatory scope were compared and analyzed.
