This study compared and evaluated the wind resources of North and South Korea macroscopically in the preparation for future energy cooperation. To this end, the Korea wind resource map of the Korea Institute of Energy Research, in which its accuracy has been validated, was used. The onshore wind resource was analyzed by the terrain elevation category, while the offshore wind resource was analyzed by the water depth and distance to shore categories. North Korea was found to have a five times larger feasible onshore area, where the wind class is over level 3, and a 2.1 times larger feasible offshore area, where the wind class is over level 4, water depth is less than 50 m, and distance to shore is less than 70 km. On the other hand, despite the average terrain elevation of North Korea being double that in the South, the average wind power density of onshore in North Korean is similar to that of South Korea, while the average wind power density offshore in North Korean is lower than that of South Korea. The feasible area of the wind farms identified in this study will be used to establish renewable energy development strategies of North Korea in the near future.
