Researchers from ETH Zurich and ZHAW Winterthur are simulating in a new study how the future Swiss power system could be structured to withstand a drastic fall in gas and electricity imports. By doing so, they aim to contribute to the discussion surrounding Switzerland’s supply security.

An international team of researchers has examined the environmental, social, economic and legal aspects of wind energy. In this interview, Russell McKenna, an expert in energy system analysis, explains where he sees the greatest need for action to further develop wind energy.

Researchers at ETH Zurich have developed a climate-friendly covering for walls and ceilings that temporarily stores moisture, creating a comfortable environment in heavily used indoor spaces. The covering components are made of mineral waste materials and are produced by means of 3D printing.

On the Pic du Midi in the Pyrenees, ETH Zurich researchers have analysed particulate matter, clouds and rainwater for traces of arsenic. Using newly developed measurement methods, they have elucidated the transport pathways of the environmental toxin in the atmosphere.

Geophysicists at ETH Zurich are using models of the lower mantle to identify areas where earthquake waves behave differently than previously assumed. This indicates the presence of zones of rocks that are colder, or have a different composition, than the surrounding rocks. This finding challenges our current understanding of the Earth's plate tectonics – and presents the researchers with a major mystery.

Deep geothermal energy is climate-friendly and base-load capable - but how can this heat be tapped safely? ETH researchers are working on minimizing the earthquake risk and developing completely new systems, for example with closed CO₂ cycles.
