Energy wasting is a concern for everyone: The CREST project explores different paths of removing energy wastage through more efficient and sustainable energy usage. Based on experimentation, the CREST project works by using the “living labs” principle. New opportunities and solutions will emerge through common users, common professional behaviours and common lifestyles which will cause energy consumption to decrease. This is why the CREST project aims to make everyone in society aware of the opportunities so behaviours can be changed to reduce energy wastage. Moreover, the CREST project works on different jobs linked to renewables in order to valorise and increase employment in this field.
