The local government of Viladecans, in Barcelona, set up an energy company based on citizen participation to promote the shift to environmentally friendly power sources and the renovation of homes to make them more energy efficient. In addition, a digital currency was created to reward people for saving energy. The money could be spent at businesses in their area to boost the local economy. The wider goal was to ensure the sustainable use of resources in a socially just community in which citizens play an active role.
