In line with the results of the recent referendum on the revised Energy Act, a representative survey conducted by Eawag environmental economists found that 78 per cent of the Swiss population support the phase-out of nuclear power. Read more

The aeroplane Solar Impulse demonstrated the potential of clean-tech innovations. For countries like Switzerland, investment in photovoltaic research and development is more promising than the production of solar panels. Photo: Solar Impulse

The emergence of new technologies requires conditions tailored to specific industrial sectors. Social scientists at Eawag have developed a conceptual framework describing the relevant innovation drivers. This should make it possible to identify factors hindering innovation and to design industry‑specific support programmes.  Read more

In freshwater lakes, large amounts of the greenhouse gas methane are oxidized by bacteria before it can be emitted into the atmosphere. A study in Lakes Rotsee and Zug has now shown that the bulk of this work is done, not by “classical” methane consumers, but by filamentous bacteria previously known only as contaminants of water supplies.

Bypass tunnels designed to reduce sediment deposition in reservoirs also have beneficial effects on ecological conditions in downstream receiving waters. This was the conclusion of a study carried out on the Solis reservoir in Graubünden by biologists from Eawag and the Zurich University of Applied Sciences (ZHAW).  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
