From Cleanwatts' solar energy communities to off-grid systems, rainwater harvesting and drought resilience, the practical infrastructure of a sustainable life in Portugal. If you run a project in this area, we'd love to list it.

This is the infrastructure layer of a sustainable life: where the power comes from, where the water goes, and how you move between the two. In a country with long summers and shortening rivers, water is the question that keeps returning.
Cleanwatts builds solar energy communities, where neighbours share what a roof generates instead of each buying their own system. Alongside it sit off-grid households, rainwater harvesting, greywater reuse and reed-bed purification, and the drought-adaptation work that the Alentejo in particular has been forced into.

If you run a project in this area, we would rather list it than leave a gap. Dated activities from these projects are listed in our events calendar.
