China's Green Energy Machine Is Eating AI's Power Bill—and Southeast Asia's Grid

Chinese energy companies are showcasing green and digital solutions at ADIPEC 2026, one of the world's largest oil and gas exhibitions, presenting technologies designed to reduce emissions and improve efficiency in the energy sector [1]. Their presence highlights China's growing role in the global push toward cleaner energy and digital transformation [1].

At the same time, China is turning to renewable energy to gain an edge in the global artificial intelligence race [2]. As demand for AI grows worldwide, the country needs massive data centers to power the technology [2]. China's large wind, solar, and battery industries can supply these facilities with cheaper electricity and bring data centers online faster by reducing reliance on conventional power sources [2].

The country's renewable buildout is also crossing borders. In southern Laos, 133 Chinese-built wind turbines now supply electricity to Vietnam, highlighting a regional push to diversify energy sources beyond hydropower [3]. The turbines stand along the green ridgelines of southern Laos [3]. Local resident Toukta Phonsala, 23, described them from her wooden stilt house in Dak Wai village: "The view is beautiful. They're bigger than trees" [3].

Hydroelectric dams have spread rapidly across Southeast Asia in recent years, but dam output falls during the dry season, and critics have raised concerns about their environmental and social impact [3].

China's dual role—as both the world's largest greenhouse gas emitter and a leading provider of green technology—remains a point of tension. It bears responsibility for South Asia's climate crisis both because of its emissions and because it has the capacity to act as a leading provider of green technology and an upstream player in the region's climate chain [4].
