From one month ago, on August 15, 2025, discussions and preparations for this conference were in full swing, with participants finalizing their presentations and networking to ensure impactful collaboration. Looking back one year, on September 15, 2024, a significant report on global carbon emissions was released, prompting urgent calls for action among nations and industries, setting the stage for the upcoming conference. Five years ago, on September 15, 2020, the world was grappling with the COVID-19 pandemic, which had a profound impact on energy consumption patterns and accelerated discussions around green recovery initiatives. Ten years ago, on September 15, 2015, the United Nations adopted the Sustainable Development Goals, emphasizing the importance of affordable and clean energy as a critical component for sustainable development.

Fast forward to 1000 years ago, on September 15, 1025, societies were primarily agrarian, relying on manual labor and natural resources for energy. The concept of renewable energy as we know it today was non-existent, but communities were beginning to harness wind and water for milling and irrigation, laying the groundwork for future advancements in sustainable practices. Thus, the date of September 15 holds significance across the ages, reflecting humanity's evolving relationship with energy and sustainability.
