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