The Alpine solar power plant on the Muttsee dam in the canton of Glarus has been in operation since 2022. Source : Axpo Researchers from EPFL and HES-SO Valais have modeled the Swiss energy system under the hypothetical constraints of carbon neutrality and energy independence by 2050. The results show that these two constraints could be met while reducing energy system costs by about 30% compared to 2020. A carbon-neutral and independent Swiss energy system in 2050 is theoretically achievable using the currently untapped local renewable energy resources. This system would even be cheaper than the country's 2020 energy system modeled with the same assumptions, with up to 30-32% cost reductions. Such are the findings of an extensive study led at EPFL and HES-SO Valais, that have the potential to pave the way for a reinforced plan towards more domestic investment in clean energy. Though theoretically possible, the total independence of the Swiss energy system is not a goal per se.
