Success stories


Technical instruments for renewables promotion

Success stories

Subsidy programmes (by power company, by the City)

Funding and financing schemes (e.g., „regional power“ electricity label, innovation funds for climate protection )

Urban development programmes(e.g., Vauban, Rieselfeld; sparking off building industry innovation)

Energy concepts for all new developments and redevelopments

Provision of roofs and other surfaces (PV as second benefit)


Structural instruments for renewables promotion

Education (schools projects)

Research and development (ISE, Solar University, Solar Info Center …)

Training (skilled trades, technicians)

Technology and knowledge transfer (Italy, Korea …)

Success stories


Political consensus in Freiburg

Success stories

Economy and environment combine as material benefit

Cessation of nuclear energy

Strong municipal influence on energy policy (e.g., foundation of badenova power company)

Supportive framework for intrinsic motivation rather than push and pull
