Global Spread and Challenges of Clean Energy India, the world's third-largest carbon emitter, recorded its lowest CO2 emission growth rate in 20 years as of 2025. This is not merely a statistical shift but a significant signal that the structural transition to clean energy has begun to yield tangible results. An analytical report by Lauri Myllyvirta and Anubha Aggarwal, published by Carbon Brief, a specialist climate data analysis media outlet, re-examines the significance of India's energy transition in global climate change efforts and offers crucial implications for other countries, including South Korea. India, which historically relied heavily on a coal-centric energy system, has now reached a major turning point, attempting a clean energy-based transition. While India's CO2 emissions remain the third highest globally, the significant slowdown in its growth rate is noteworthy. This achievement is a result of a combination of government policy support, technological innovation, and active investment from private companies, leading to a re-evaluation of India's role in the global trend towards carbon neutrality. According to Carbon Brief's report, India's power sector CO2 emissions decreased by 3.8% as of 2025. This reduction is primarily attributable to two factors. First is the record-breaking increase in solar and wind power generation. The surge in renewable energy generation has led to a relative decrease in the share of coal-based power. Second is the slowdown in electricity demand. The moderation in electricity demand growth, driven by adjustments in economic growth and improvements in energy efficiency, has reduced the need for additional fossil fuel-based generation. The combination of these two factors has resulted in tangible carbon emission reductions in the power sector. Myllyvirta and Aggarwal emphasize in their report how rapidly India's renewable energy infrastructure is expanding. India, which relied on increasing coal-based power generation as recently as the early 2020s, has significantly expanded its installed capacity for solar and wind power in recent years. This was made possible not only by the central government's renewable energy policies but also by the active participation of state governments and private companies. In particular, the continuous decline in solar power generation costs has improved economic viability, creating a virtuous cycle that has led to increased investment. The transition to clean energy is not merely about meeting environmental demands. Today, clean energy has become a critical factor determining economic growth and industrial competitiveness. India's case demonstrates that renewable energy is no longer a future possibility but a currently viable alternative. The remarkable growth of solar and wind power brings multi-faceted benefits, including strengthening energy security, reducing reliance on fossil fuel imports, and creating new jobs. However, not everything is smooth sailing. The report points out that, in contrast to the achievements in the power sector, CO2 emissions in the industrial sector, particularly in steel and cement industries, are still increasing. These industries inherently emit large amounts of carbon during their manufacturing processes and are technologically challenging to decarbonize. Myllyvirta emphasizes that a long-term perspective and strategic approach are necessary for the renewable energy transition to spread across all industries. In other words, even if the energy transition is successfully achieved in the power sector, there will inevitably be limitations in achieving overall carbon neutrality goals if these changes are not extended to related areas such as manufacturing, transportation, and construction. This point has significant direct implications for South Korea. As an advanced technology-based nation, South Korea has achieved a certain level of development and dissemination in renewable energy technologies but still faces structural problems centered on fossil fuels. South Korea's industrial structure is dominated by carbon-intensive manufacturing, including steel, petrochemicals, and cement, which acts as a major obstacle to achieving carbon neutrality goals. The issue highlighted by India's increasing industrial sector emissions is a challenge that applies equally to South Korea. Implications of India's Energy Transition for South Korea South Korea can learn several lessons from India's case. First, bold and continuous investment in renewable energy infrastructure is necessary. India made large-scale investments in solar and wind power, reducing generation costs and rapidly expanding installed capacity. As renewable energy generation costs continue to fall, South Korea must actively leverage this trend to reduce its reliance on fossil fuels. In particular, there is a need to strategically develop renewable energy sources suitable for South Korea's geographical conditions, such as offshore wind power. Second, the
