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.

There will be no general shortage, but water may be scarce depending on the region and time of year – conversely, heavier rainfall will lead to more local flooding. These are the findings of the Hydro-CH2018 project published today, Hydrological Principles of Climate Change. The extensive study with collaboration of the Eawag Water Research Institute was carried out under the lead of the Federal Office for the Environment (FOEN) in conjunction with the National Centre for Climate Services (NCCS). Climate change means that our use of water will have to change in future.

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.
