Ambitious nuclear and rooftop solar expansion to avoid landscape-impacting wind and alpine solar units
Preserving landscapes
Protect natural, unspoiled areas by avoiding large-scale energy projects
Leveraging nuclear energy
New nuclear power plants ensure a long-term, climate-neutral electricity supply
Expanding rooftop solar
Massive installation of rooftop PV systems without impacting the landscape
Minimizing imports
Limited but necessary electricity imports to cover the winter power shortfall

Import limits exceeded
The energy law limits our imports to 5 TWh. This will be exceeded in 2020 - 2046.
Landscape preservation
Avoiding impacts on natural landscapes restricts the expansion of renewable energy projects
Delays due to opposition
Projects are delayed or blocked by opposition and public referenda
Technological and investment risks
Building new nuclear power plants is currently banned and involves high economic risks for investors
Dependence on rooftop PV
Missing winter energy from ground-mounted or alpine solar must be compensated through rooftop PV and imports
