This study examines the necessity of energy system integration (ESI), the challenges in its implementation, and the policy directions towards promotion of new and renewable energy in order to achieve carbon neutrality. Although the overall transformation of the economy, industry, and society is essential for achieving carbon neutrality, the most important aspect is the implementation of ESI that aims for a highly efficient transformation process. ESI comes with its own challenges such as securing sufficient new and renewable energy sources, securing technological alternatives for energy conversion, converting the power system to use renewable energy as the main power source, and securing green hydrogen. Overall, these policies could lead to ensuring a fundamental transformation of the energy system and providing an opportunity for accelerating decarbonization. We must actively respond to this change and take advantage of opportunities.
