A balanced build-out of renewables, focusing on solar and wind. Green gas as winter-backup
Balanced Renewables Mix
A diverse range of renewable technologies, with a focus on securing domestic winter supply.
Alpine Solar and Wind in Winter
Alpine solar and wind bolster energy generation, especially in winter.
Harnessing Solar Power
Expanding ground and rooftop solar to meet a growing share of energy demand.
Sustaining Hydropower
Hydropower remains crucial for flexibility and reliability.
New Consumers Drive Demand
Electromobility, hydrogen, and heat pumps are increasing demand more than efficiency efforts can offset.
Gas secures supply in Winter
Gas, including hydrogen, replaces nuclear in winter after decommissioning

Challenges
Import Dependency
Import needs after nuclear decomissioning require neighbor surplus and EU agreement
Public Opposition
Public may oppose new infrastructure (wind, alpine solar) due to landscape concerns
Weather Dependency
System gets more and more weather-dependent with wind, solar and hydro
Reliable Backup Needed
Backup, e.g. gas or nuclear may be required when imports are limited and renewables fall short
