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.

Eawag and the Eawag spin-off Vuna have made urine fertiliser production mobile. Today, the Urine Express will be presented at a very special location in Biel: next to the first public grass tennis court in Switzerland. In future, the tennis court is to be fertilised with urine fertiliser.

What developments do urban water researchers and professionals see as important – or worthy of scepticism? A pioneering horizon scan conducted by Eawag scientists indicates that, for this community, digitalisation is a particular concern – in a positive and negative sense. In this interview, Frank Blumensaat, an environmental engineer at ETH Zurich and Eawag, discusses the opportunities and risks it creates in the urban water field.

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.
