Neighbors can influence your decision to buy solar panels
Neighbors can influence your decision to buy solar panels
An EPFL study carried out in Vaud Canton has shed light on the factors that can prompt people to buy solar panels. It found that having neighbors with solar panels plays a significant role, alongside more well-known influences, such as our social circle. If you're a homeowner, have a high-level job, and have friends or family members with solar panels, chances are that you've got them, too.

Unraveling complex systems: the Backtracking Method
Unraveling complex systems: the Backtracking Method
Scientists at EPFL and Charles University have developed a new method to analyze the dynamical, out-of-equilibrium properties of complex disordered systems, such as gold with magnetic impurities or opinions spreading on social media. In physics, a "disordered system" refers to a physical system whose components - e.g. its atoms - are not organized in any discernible way.

Computational Model Paves the Way for More Efficient Energy Systems
Computational Model Paves the Way for More Efficient Energy Systems
Researchers make theoretical breakthrough in thermoelectric material to better harness waste heat for sustainable energy. Around 70% of the energy we use in everyday life is wasted in the form of heat, produced by engines, factories, and electrical devices. However, researchers from EPFL's School of Engineering have made a significant theoretical step forward that could boost sustainable energy generation.
