Switzerland's energy transition

To achieve its goal, Switzerland must double its photovoltaic capacity every decade, with power from wind, hydrogen fuel cells, and imports also contributing. Electric vehicles and heat pumps will become crucial, while energy savings through building renovation are essential for meeting the target.

What can stream quality tell us about quality of life?

Researchers found a strong correlation between stream conditions and human demographics, particularly along racial lines. Stream quality is linked to mortality rates and cancer rates, highlighting the need for environmental justice. Understanding how people interact with nature is crucial to drawing conclusions about health outcomes.
