Switzerland's commitment to low-carbon electricity is commendable, achieving 100% of its electricity generation from clean energy sources over the past 12 months, from November 2023 to October 2024. Hydropower remains dominant, accounting for nearly half of the electricity produced, complemented by nuclear energy, which adds another substantial portion at about 44%. Solar energy has been making a noticeable contribution, providing just over 8% of the country's electricity. This remarkable shift away from fossil energy makes Switzerland a vital net exporter of electricity, helping neighboring countries reduce their emissions. The future challenge lies in electrifying other sectors such as transport, heating, and industry, which will demand a significant increase in clean electricity supply.
To meet the growing electricity needs while maintaining its low-carbon status, Switzerland can capitalize on expanding its nuclear energy capabilities. Given the robust infrastructure of the existing nuclear plants, further development in this sector can amplify their already substantial contribution to the energy mix. Alongside nuclear expansion, a push to enhance solar power deployment can provide additional capacity, especially during periods of high demand. These strategies ensure a sustainable increase in electricity production without compromising on environmental targets, reinforcing Switzerland's position as a leader in clean energy.
Examining the history of Switzerland's low-carbon electricity generation reveals strategic shifts and challenges over the decades. The mid to late 1980s marked a period of growth in nuclear energy, peaking in 1985 and 2006, indicating deliberate expansion. However, notable challenges occurred in the 2010s and early 2020s, with fluctuations in hydroelectric generation, notably declines in both 2011 and again recent steep declines in 2022 and 2023. Meanwhile, nuclear generation encountered setbacks, such as in 2015 and 2021, underscoring the need for continuous investment and upgrades in the sector. Nevertheless, nuclear power remains a vital and efficient pillar of low-carbon electricity production, capable of ensuring a stable and environmentally friendly energy future for Switzerland.
