Today, Uruguay produces nearly 99% of its electricity from renewable sources, with only a small fraction—roughly 1%–3%—coming from flexible thermal plants, such as those powered by natural gas. They are used only when hydroelectric power cannot fully cover periods when wind and solar energy are low. The energy mix is diverse: while hydropower accounts for 45%, wind can contribute up to 35% of total electricity, and biomass—once considered a waste problem—now makes up 15%. Solar fills the gaps.
