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.
The use of our water bodies for hydropower or for heating and cooling influences a river’s bed load and sediment regime as well as its aquatic organisms. Eawag researchers study the environmental impacts of energy production and are actively engaged in consulting, for example concerning nuclear energy or methane extraction from lakes.

Environmental social sciences mainly address the social impacts of the energy transition such as the acceptance of hydropower or of alternative energy supply.
Nutrient recovery, e.g. nitrogen and phosphorus from urine, saves a lot of energy because less artificial fertiliser has to be synthesised by an energy-intensive process. Not only nutrients can be recovered from wastewater, but also heat and other forms of energy. Therefore, future wastewater treatment plants may act as power plants.
