Selecting sustainable renewable energy source for energy assistance to North Korea
Introduction
North Korea has been facing an energy crisis that it has not been able to solve through internal means [2], [3]. While there is a desperate humanitarian need to provide North Korea with energy assistance, there are also numerous prerequisite issues that need to be addressed. Past and current energy assistance policies for North Korea, such as KEDO, heavy fuel oil aid, and direct power transfer, that the international community (to include South Korea) have implemented do not provide a fundamental or a permanent solution to resolving North Korea's energy problems. Energy assistance policies utilized thus far has faced several problems [4], [5]. The outdated facilities and aging infrastructure of the North Korean energy sector make direct energy transfer (heavy oil and power) ineffective. South Korea and the international community discovered the truly decrepit nature of North Korea's energy infrastructure during the KEDO light-water reactor project [6]. North Korea has made a concerted effort to improve the situation; however, it has had little to no effect. Heavy fuel oil transfer has been delayed due to social and political controversies the heavy fuel oil transfers spark internal to the donor nation-states as well as the shortage of fuel storage facilities in North Korea [7]. There is a need for the North Korean government's political and physical will to truly resolve its energy shortage problem. As such, any policy planner who is working to implement an energy assistance policy for North Korea must first determine the North Korean Government's policy direction and then seek to find a cooperative framework that is compatible with it. Furthermore, the future energy assistance policies for North Korea, instead of being pedestrian short-range policies, must encourage internal changes and development of North Korea and fundamentally resolve the North Korean energy crisis by providing new energy technology transfers, facility and equipment support, infrastructure acquisition and expansion, and by encouraging international cooperation.
RE is the most appropriate energy to resolve the North Korean energy shortage while overcoming the various issues involved with providing North Korea with energy. First reason is that the inter-Korean RE cooperation would be consistent with the policy direction of the North Korean government. Secondly, technology transfer effects can be expected beyond the one-dimensional or simple energy transfer. Thirdly, considering the state of the energy infrastructure and T&D network of the North Korea, RE, which utilizes localized energy system, is a reasonable alternative [8], [9], [10]. Fourthly, North Korea has already shown its desire to actively develop RE and North Korea has high potential for future RE development [11], [12]. Fifthly, the inter-Korean RE cooperation can influence publicity both domestically here in South Korea and internationally; avoid the pitfalls of the issues related to nuclear problem, international relations, or technology diversion to the North Korean military; and North Korean government is more likely to be amenable to the construction of RE facilities within its borders.
RE assistance to North Korea is expected to bring about the international community's political cooperation out of the spirit of humanitarian assistance. Economically, South Korea's RE market can potentially benefit and expand from increased demand. Over the long-term, South Korea can prepare for the unification of the peninsula as it constructs and upgrades North Korea's energy infrastructure [13]. Other researches in this subject have shown that the inter-Korean RE cooperation is appropriate because RE utilizes localized energy system; is consistent with North Korea's policy direction; and is appropriate for the environmental conditions of North Korea. The core of the North Korean RE technology development policy, in fact, is built around balancing energy, environment, and ecological aspects, and the aim of the North Korean energy policy is to satisfy environmental requirements while satisfying demand and security requirements by increasing production of sustainable domestically produced energy – a very sound policy goal. The international community has already provided North Korea with wind power, solar power, solar heat, and biogas facilities, which were in line with the existing North Korean RE policy goals.
While other researches on this subject conducted surveys and collected experts’ opinions [14] or selected alternatives using qualitative methods [15], this research, in contrast, surveyed technical and political experts’ opinions using AHP with BOCR method focused on selecting those RE sources that can be utilized for sustainable inter-Korean energy cooperation for the mid- and long-term, with the ultimate goal of energy independence for North Korea through technical cooperation that is firmly grounded in a theoretical methodology.
The concept of “sustainable” was important for this research because the North Korean energy problem cannot be solved by one or two simple aid plans. To solve North Korea's energy problem, one must be able to supply enough energy to solve the daily energy shortage in the short-term and an internal system must be established that can meet the future energy demands without external assistance in the long-term. It is in this perspective, this research defined the characteristics of new and renewable energy that can satisfy the needs for short-term energy transfer, mid-term energy relief, and long-term energy independence as the concept of “sustainable.”

Analytic hierarchy process (AHP)
Analytic hierarchy process (AHP) is one of the decision making tool which is designed to make decision between several alternatives with multiple factors using multi-dimensional evaluation criteria. AHP is proposed by Tomas. L. Saaty in late 1960s. AHP provides a comprehensive framework by considering quantitative and qualitative factors based on the intuitive and rational/irrational judgments of the respondents. The best feature of the AHP is that it divides complex issues into key factors and
Survey construction and panel selection
AHP is a method that obtains data through surveys; therefore, the entire research is influenced by the composition of the survey panel, making panel selection an extremely important phase of the research. For this research, the panel was composed of both Korean and foreign university professors, state-run research institute researchers, representatives of international and non-governmental organizations, representatives of private think tanks and consultation companies, government officials,
Discussion
In this research, other than analyzing the overall consensus of the whole panel on the selection of appropriate RE source to provide energy assistance to North Korea, it also subdivided the panel into three sub-panels based on the panel member's expertise and characteristics. The three sub-panels were engineers, Korean political and security experts, and foreign political and security experts. The result was that this research was able to determine the differences in perspectives and interests
Conclusion
This research was conducted under the theoretical base of the AHP-BOCR. The result is more reliable than the previous researches conducted on this similar topic because of the theoretical underpinnings this analysis was based on. AHP method as described above provides a comprehensive framework for decision-making. Thus, it helps to achieve the purpose of this study efficiently with high reliability.
This study also has distinct characteristics to other studies that it includes a panel of experts
