In 2024, Portugal's electricity consumption showcases a strong emphasis on low-carbon sources, with more than three-fourths of its electricity derived from clean technologies. The largest contributor is hydropower, providing about 38% of the electricity. Wind energy follows as another significant source of low-carbon electricity at over 23%. There are also substantial contributions from net imports, which likely include clean energy, accounting for almost 17% of the electricity consumed. Fossil fuels contribute a relatively small portion, with 8% coming from gas. Solar power forms a notable part of the low-carbon mix at about 8%, further diversifying the clean energy contributions, while biofuels round out the low-carbon landscape. This diverse mix underlines Portugal's commitment to reducing carbon emissions and fostering sustainable electricity generation.
To further boost low-carbon electricity generation, Portugal could expand its wind energy capacity, building on its already substantial wind power sector. Learning from Denmark, which generates close to 60% of its electricity from wind, Portugal can investigate policies and technologies that facilitate large-scale deployment of wind infrastructure. Additionally, exploring nuclear energy could be beneficial. While not currently part of Portugal's electricity mix, similar European countries like Slovakia and France have successfully incorporated nuclear power, making it a major part of their low-carbon portfolios. Through international cooperation and adopting best practices from these countries, Portugal could enhance its clean energy footprint, ensuring a stable and sustainable supply of electricity.
The history of low-carbon electricity in Portugal has seen notable ups and downs, particularly with hydropower. In the late 1970s, there was a substantial increase in hydropower generation, adding significantly to the clean energy mix. However, the following decades saw fluctuations, with the 1980s and 1990s experiencing notable downturns in hydroelectric production in certain years, often followed by recoveries such as in 1996 and 2003. The 21st century has also brought turbulent changes, but with a strong focus on increasing capacity, as seen in recent years like 2013 and 2024, where substantial increases were recorded. These trends highlight an evolving landscape, indicating both the challenges and the potential within Portugal’s commitment to fostering reliable and green electricity production.
