Switzerland's energy supply should be climate-neutral and nuclear-free by 2050. A new research report shows that photovoltaics and wind power must be massively expanded. At the same time, access to the European electricity market remains crucial in order to guarantee security of supply and

Researchers at TU Berlin have achieved a breakthrough: They have developed a new class of silicon-based super Lewis acids that can break down even extremely stable compounds such as PFAS. This opens up prospects for green chemistry, recycling processes and the degradation of highly hazardous

Urban Sympheny AG has completed ESRI's three-year start-up programme. During this time, Sympheny has integrated ESRI's geodata technology into its services. These are designed to support the planning and management of energy systems using digital

The Langmatt Museum is producing solar power as part of its complete refurbishment. On the roof of a newly constructed glass pavilion, a photovoltaic system from Regionalwerke Baden will supply the museum and the complex with sustainable energy in

The city of Zurich and ewz are committed to expanding solar power production in Zurich. In future, local communities are to be created in which owners of larger solar installations sell surplus electricity directly to households in the

Energy-efficient renovations are crucial to achieving Switzerland's climate and energy targets. However, the current proposal on the imputed rental value threatens to slow down investment and weaken the construction industry. A new study shows how much untapped potential there is in the building

Nuclear waste is seen as a burden for future generations, but researchers are now discovering an opportunity. Radioactive waste could help to produce the urgently needed fuel tritium for nuclear fusion. This brings closer a technology that could supply enormous amounts of energy and give a decisive

The city of Lucerne wants to create around 30 public locations with charging infrastructure by 2035. To this end, it is making public land available to third-party providers in return for a concession fee and investing just under CHF 1 million. Other measures are also intended to promote the

In future, Energy Vault will handle project planning, construction, commissioning and service contracts via the new subsidiary Asset Vault. This is to receive an investment of USD 300 million from an infrastructure fund and place all orders with Energy

The Magadino Plain in the canton of Ticino is a transportation hub, supply hub and unique natural landscape all in one. Around a third of the plain is protected as a moorland landscape of national importance. In order to reconcile the protection of this sensitive environment with future rail, road

On August 1, 2025, numerous legal changes came into force in Switzerland, affecting work, safety, education, the environment and aviation. Here is an overview of the most important changes, from cyber security to bans on cell phones in schools and new rules in residential

STRABAG is realising the NalpSolar project in Graubünden for Axpo. An alpine solar plant with a technology centre is being built here next to the Lai da Nalps reservoir above Serdun. The first electricity is expected to flow as early as December

Researchers at the University of Minnesota Twin Cities have developed a method to control the flow of electricity in ultra-thin metal films at room temperature using light. This discovery could revolutionize the development of new, highly efficient components in optoelectronics and quantum

Underfloor heating can do more than just heat. In combination with a suitable heat pump, it becomes a quiet, efficient and environmentally friendly cooling solution in summer. The article shows how active and passive systems work, where their limits lie and what is important when

Photovoltaic systems with an output of 1.8 gigawatts were installed in Switzerland in 2024. This was 10 per cent more than in the previous year. At the end of 2024, a total of 8.2 gigawatts were installed. The industry association Swissolar expects this to generate 14 per cent of electricity in
