This document discusses technology transfer between Korea and other countries, using Korea's experience with ESCO projects as a case study. It describes how an ESCO project was conducted between a Korean company and US partner to identify energy efficiency opportunities at a Hyundai Motors factory. While the project identified some opportunities, it faced barriers like different funding systems and regulations between the countries. The document concludes that technology transfer must be considered within the context of a country's strategies and circumstances, and that experience with the evolution of technologies over time is important.
