Reasonable usage methods of energy resources, which are limited for human beings to use, consists of new & renewable energy (NRE) and demand side management (DSM). All technologies and policies for energy resources are classified into two fields, methods for using new energy resources and methods for using conventional fuel energy resources. Various development activities for these fileds have been implemented and various subsidy programs have been operated to penetrate into markets rapidly. These subsidy programs have various types of subsidy by energy resources and programs and the budget are funded by government, which is called Electric Power Industry Basis Fund and is managed considering technology level, economic analysis, global environment, etc. These subsidy programs are managed by Korea Energy Management Corporation (KEMCO) for NRE and by Korea Electric Power Corporation (KEPCO) for DSM, the management are different among two corporations because the purposes and features of establishment are different though these are all public organization. KEMCO is managing the NRE subsidy programs according to the government will, while the management of KEPCO subjects to power system operations though the government will for DSM is considered. NRE which is on the initial phase of diffusion would not affect on power system seriously but the affects could be grown when the diffusion and importance are expanded. Hence some integrated affection analyses considering NRE and DSM are required and this paper shows the concept of integrated operation strategies with ground source heat pump systems which are related with two fields simultaneously.

The photovoltaic (PV) industry, which occupies about 80% share of domestic new and renewable energy (NRE) sales, has played an important role in the development of the Korean NRE industry. This was made possible by the government's implementation of the 3rd Basic New and Renewable Energy Plan, which promoted strategic PV R&D, infrastructure building, and a variety of PV deployment programs. For instance, 'One Million Green Homes', 'Feed in Tariff', and 'Renewable Portfolio Standards' programs contributed greatly to the dissemination of PV systems in the country. Furthermore, these programs were supported with more than 380 billion Won over 6 year period (2007~2012). The strategic PV R&D contributed to the fast follow-up in commercial technologies. Because of the recent, sharp decline in PV prices caused by oversupply and economic crisis in European countries, both foreign and domestic PV companies are going through painful restructuring. Under these circumstances, the Korean PV industry needs to find a new strategy for making a breakthrough, and in this sense a proactive role of the Korean government is desperately needed.

This paper presents an adaptive strategy of GENCOs for reducing the greenhouse gas by fuel mix change. Fuel mix stands for generation capacity portfolio composed of different fuel resources. Currently, the generation sector of power industry in Korea is heavily dependent on fossil fuels, therefore it is required to change the fuel mix gradually into more eco-friendly way based on renewable energies. The generation costs of renewable energies are still expensive compared to fossil fueled resources. This is why the adaptive change is more preferred at current stage and this paper proposes an optimal strategy for capacity planning based on multiple environmental scenarios on the time horizon. This study used the computer program tool named GATE-PRO (Generation And Transmission Expansion PROgram), which is a mixed-integer non-linear program developed by Hongik university and Korea Energy Economics Institute. The simulations have been carried out with the priority allocation method in the program to determine the optimal mix of NRE(New Renewable Energy). Through this process, the result proposes an economic fuel mix under emission constraints compatible with the greenhouse gas mitigation policy of the United Nations.

Nowadays the concern about development and diffusion strategies of new & renewable energy (NRE) and its technologies are getting higher globally as Kyoto Protocol has taken effect this year and oil has been rising in price tremendously. Developed countries have already commenced the study and research for this problem and are looking for various solutions. In this paper, the support Priority of NRE technologies are determined by horizontal comparison analyses.

August 2008, Our country was announced the Energy Vision 2030 for strengthening response capability climate change by the greenhouse effect, 'Stable supply of energy' and 'Efficient systems'. According to the report, Our country is the world's top 10 is a country that consumes a lot of energy. and more than 97% of the energy because it is dependent on foreign imports, The importance of NRE(New and Renewable Energy) is rising significantly, This paper was applied geothermal heat pump it one kind of the renewable energy equipment, in General buildings, and analyzed the effect of the installation. Thus, to improve the load factor of the Electric power system was proposed, and As a result, can be expected the energy cost savings and the reduction of greenhouse gases, through Economic electric power supply.

Green infrastructure projects have the potential to reduce global warming and deliver sustainable energy solutions. Recently, the construction industry has been expanding their portfolios in New and Renewable (NRE) projects. However, the economic feasibility of NRE projects have not been validated and construction companies are not acquainted with their associated risks. This research performed a two-tiered feasibility study of the domestic projects registered for CDM in the UNFCCC. The first phase involved calculating the average IRR and NPV of the domestic CDM projects, which showed that their profitability to be very low. In the second phase, four NRE projects (Solar, Wind, Hydro, Landfill Gas) were selected and additional income generated from Feed-in-Tariff and CER sales were added to determine the improvements in the projects' IRR and NPV. Results indicate that Solar and Landfill Gas projects benefited the most from the two support mechanisms, while benefits to Wind and Hydro projects were minimal. While the Landfill Gas project had the highest IRR, the Wind project was the most investment attractive due to its NPV and minimal dependency on FiT and CER sales. Construction companies should enter into NRE projects with a long term view as related technologies mature.

Nowadays the concern about development and diffusion strategies of new & renewable energy and its technologies is getting higher globally as Kyoto Protocol has taken effect this year and oil has been rising in price tremendously. Developed countries have already commenced the study and research for this problem and are looking for various solutions. In this paper, R&D environments and diffusion status solar thermal energy in the United States are analyzed and the probability of application into Korea case is observed. To achieve this observation, correlations between US case and Korea case is estimated and the variation of duration and amounts in R&D and the R&D contribution to national economic growth are considered.
