Environment-friendly Energy Transition

Switzerland has firmly resolved to pull out of atomic energy in a step-by-step program. The Federal government’s Energy Strategy 2050 envisions the expansion of hydroelectric power and the increased use of other renewable energy sources. Eawag is researching the impacts of this energy transition on Swiss waters and society and developing processes for a more efficient use of energy from various sources.

The residual flow in the Sarine River is insufficient to maintain its dynamic flow. Research is currently being carried out as part of the “Energy Turnaround” National Research Programme (NRP 70), to ascertain whether hydropower can be made more environmentally friendly through controlled experimental flooding. The first experimental flood event has taken place, and researchers are now analysing all the data and records that have been collected. Read more

Hydropeaking operations at storage hydropower plants affect hydrological processes and have adverse impacts on river ecosystems. For example, rapid and intense fluctuations in discharge can cause fish and macroinvertebrates to be flushed downstream or stranded. Read more

The VUNA recycling process, which recovers nutrients from urine, recently had its own display as part of an exhibition at the “Umwelt Arena” (Environment Arena) in Spreitenbach. Eawag’s exhibit was designed to raise awareness amongst visitors to the exhibition of the fact that wastewater also contains reusable substances, which can be used, for instance, for making fertilizers.

Strategic area of focus "Energy"

Within the framework of the ETH Domain’s strategic area of focus «Energy», Eawag investigates the environmental impacts of energy production, the acceptance of alternative energy supply, the potential for energy savings and energy production from wastewater. Click for a complete project list.

Selected research projects

Watercourses are among earth's most biodiverse ecosystems. However, they are also under severe pressure from construction work and hydropower generation, among other things.
Sustainable urban water and wastewater management applied and implemented in the modular NEST building.
This project aims at providing a better insight into the public preferences of the Swiss population for the suggested hydropower expansion.
