East Asia and the Pacific region stands tall as the undisputed global leader in hydroelectric power.
With a staggering 548 gigawatts (GW) of installed capacity as of 2022, the region boasts nearly 40% of the world's total hydropower potential. This translates to clean, renewable energy powering homes and industries across the vast expanse of the region, from the towering mountains of China to the lush islands of Indonesia.
A Region on the Rise:
The region's hydropower dominance is a product of several factors. Abundant rainfall, diverse topography, and significant investments in infrastructure have all played a pivotal role. China, the undisputed leader within the region, accounts for over 90% of the installed capacity. The Three Gorges Dam, the world's largest hydroelectric power station, is a testament to China's commitment to hydropower.
But China is not alone in its hydropower ambitions. Countries like Laos, Vietnam, and Indonesia are rapidly expanding their hydropower capacity, driven by a growing demand for clean energy and a desire to reduce dependence on fossil fuels.
Beyond Capacity:
The story of East Asia and Pacific's hydropower prowess goes beyond just raw capacity. The region is also at the forefront of innovation in the sector. Pumped storage hydropower, a technology that uses excess electricity to pump water uphill for later generation, is gaining traction. Countries like Japan and South Korea are leading the way in this field, with their advanced pumped storage facilities playing a crucial role in grid stability and integration of renewable energy sources like solar and wind.
