Uruguay relies heavily on renewable energy sources, emitting significantly fewer greenhouse gases compared to the global average, with a model that integrates wind, solar, water, and biomass effectively. This transition has not only reduced electricity production costs by almost 50% but also attracted investments and created thousands of jobs, showcasing a replicable model with strong leadership and political determination.
Insights
- Uruguay's energy independence is a result of transitioning to renewable sources like wind, solar, water, and biomass waste, significantly reducing greenhouse gas emissions and exporting energy surpluses to neighboring countries.
- The country's innovative energy sector, driven by a deep energy crisis 15 years ago, showcases a successful shift from hydrothermal to renewable sources, utilizing an efficient dispatch model based on weather scenarios, ultimately cutting electricity production costs by almost half, attracting significant investments, and generating thousands of jobs.
