Switzerland wants to be climate-neutral by 2050 and at the same time phase out nuclear energy. To meet this dual challenge, a massive expansion of photovoltaics and wind power is needed. A new report by the EDGE research consortium shows in several studies how this transition could succeed. What

SENS eRecycling and Swissolar from Zurich have completed the Swiss PV Circle project together with the Bern University of Applied Sciences. The aim was to promote the reuse of photovoltaic modules. The partners formulated political recommendations, market analyses and created practical

Compressed Air Energy Storage (CAES) is a new generation of long-term storage systems. Underground compressed air systems such as the AirBattery could secure the power supply efficiently, economically and in an environmentally friendly manner, even during dark doldrums. Thanks to technical

In the first half of 2025, solar power generation reached new highs across Europe, especially in Germany. At the same time, a windless spring led to a decline in wind power figures. Despite growing photovoltaic output, the share of renewable energies in German net electricity generation fell

Aventron AG and energieUri AG have started construction of the first alpine solar plant in Central Switzerland. The photovoltaic plant in Spiringen will produce around 12.5 gigawatt hours of solar power per year from 2029. This year, 10 per cent of the plant is to be put into

The Belgian energy group TotalEnergies is introducing dynamic electricity tariffs with the help of the billing platform from the Zurich start-up Exnaton. This enables consumers to purchase renewable electricity flexibly and cost-effectively. For Exnaton, this paves the way for Europe-wide

The Swiss Federal Laboratories for Materials Science and Technology (Empa) has put the move-MEGA methanisation plant into operation. This is intended to improve the power-to-gas process by means of sorption-enhanced

Switzerland ranks at the bottom of Europe in terms of electricity production from wind and solar power. according to a study by the Swiss Energy Foundation, 11 per cent of domestic electricity production is generated in this way. This is 7.2 percentage points more than five years ago. Neighbouring

Megasol has developed special photovoltaic modules for the façade of the Bern 131 project in WankdorfCity. Together with the roof system, the shimmering blue modules will generate around 340,000 kilowatt hours of electricity. The building created by Atelier 5 is SNBS
