Hanoi, VIETNAM (AP) — The urgency for Southeast Asian nations to switch to clean energy to combat climate change is reinvigorating a 20-year-old plan for the region to share power. Malaysia and Indonesia inked a deal in Bali, Indonesia last month to study 18 potential locations where cross-border transmission lines can be set up. Those links could eventually generate power roughly equivalent to what 33 nuclear power plants would produce in a year.
