The 2025 World Climate Industry EXPO (WCE) opened on August 27 in Busan, Korea. This large-scale international event is co-hosted by the Korean government, the International Energy Agency (IEA), and the World Bank (WB) as the flagship of Energy Super Week, held from August 25 to 29. The expo features exhibitions, 12 conferences, and nearly 60 side events and programs under the theme, “Energy for AI & AI for Energy.”

The opening ceremony brought together more than 1,000 participants, including the IEA Executive Director and WB Vice President. Alongside major figures from international bodies, it also hosted 32 government delegations and 15 ambassadors and other officials from 24 embassies in Korea. Major digital companies such as Microsoft, Google, NVIDIA, and Amazon Web Services; global leading players in clean energy such as RWE, Schneider Electric, Siemens, and Bloom Energy; and homegrown corporations such as Samsung Electronics, Hyundai Motor, SK Innovation, Hanwha Qcells, and Doosan Enerbility, were also present.

In his opening remarks, Korea’s Prime Minister Kim Min-seok stated, “Korea will achieve carbon neutrality, energy security, and economic growth by constructing an ‘Energy Highway,’ expanding electricity grids, and transitioning to renewable energy.” He added, “We will work with the international community for a sustainable future powered by AI and energy.”

Keynote addresses followed. IEA Executive Director Fatih Birol projected that energy demand could grow up to six times faster in the future due to increasing use of AI, electric vehicles, and air-conditioning. He stressed the importance of grid investment, noting, “Rapid grid expansion is a shared global challenge in the AI era. Powerful and flexible grid systems are the foundation of competitiveness in the AI industry.”

Microsoft’s Director of Sustainability Policy Michelle Patron mentioned, “Grid investment is necessary to expand clean energy supply in line with demands from AI and economic growth.” She added, “To secure stable carbon-free energy supply sought by businesses, we must improve procurement methods and coordinate the connection of relevant systems, such as power purchase agreements and renewable energy certification.”

The 2025 WCE operates 6 exhibition halls, where nearly 540 companies demonstrate future energy solutions and industry strategies driven by next-generation grids, AI, and renewable energy.

This year’s highlight is the newly launched “Energy Highway” hall featuring Korea’s three major electrical equipment companies—Hyosung Heavy Industries, LS Electric, and HD Hyundai Electric. The hall showcases strategic projects of the new Korean administration, such as a West Coast high-voltage direct current network, while presenting onshore/offshore grid solutions, smart grids, microgrids, ultra-high voltage transformers, and energy storage systems.
