4 August 2026

Good morning. Today's Pulse brings a brand-new plant genus from Madeira, solar taking the top spot in the national grid for the first time, and a village in the Côa valley opening its doors to rewilding.

Nature and biodiversity

The Cobral to be renaturalised from source to mouth

The Portuguese Environment Agency says the renaturalisation project for the river Cobral is in its final drafting stage. Work will cover the whole river, with ecological recovery of the bed and banks, removal of invasive species and replanting of riverside vegetation.

Energy and the grid

Solar tops the national mix for the first time

REN figures show that in July solar became Portugal's leading source of electricity for the first time, with renewables covering 53% of consumption. Over the first seven months of the year renewables supplied 68%, even as overall demand kept rising.

The clock matters as much as the kilowatt

An opinion piece argues the energy transition depends not only on producing more renewable electricity but on when we use it, with only around 35% of consumption falling in off-peak hours. Electric car charging, clustered at midday rather than at night, illustrates the flexibility being left on the table.

Wind farm for Sines data centre goes to consultation

The Parque Eólico do Sudoeste, with 23 turbines in Santiago do Cacém, is open for public consultation on the Participa portal until 28 August. The 138 MW project, with battery storage, is intended to supply the Sines data centre directly.

Another hybrid project for the Alentejo

Chinese developer Chint Solar is advancing a solar, wind and battery project near Montemor-o-Novo, part of a 6.6 GW pipeline across the region. The article raises questions about the cumulative effects on land use, grid infrastructure and landscape.

A €4.57 electricity bill at Expofacic

Content creator Roberto Jorge visited the Solar Técnica stand at the Expofacic fair, having become a customer and now a partner of the solar company. The headline figure is a monthly bill of €4.57; most of the piece sits behind a paywall.

Farming and the land

Bluetongue support widened

The Government has amended the bluetongue support scheme to include farmers who could not vaccinate in time because of vaccine supply delays, provided they did so by 30 November 2025. The aid is €48 per registered dead sheep, with an eligibility list to be published by DGAV.

Pistachio joins Portugal Nuts

PTachio, a pistachio grower at Herdade de Vale Figueira in Arraiolos, has joined the Portugal Nuts association. The sector body now represents three strategic crops — almond, walnut and pistachio — and wants to build technical and scientific support for this emerging one.

Needs attention

Parliament presses Spain over San Juan mines

Parliament has approved a resolution urging the Government to press Spain to suspend works at the San Juan mines, near Vinhais and the Montesinho Natural Park. MPs want a cross-border environmental impact study under the Espoo Convention, given the risks to the river Rabaçal.

Circularity and resources

Three trends for greener industry

Eco-Oil points to local supply chains, turning waste into raw material, and optimising existing processes rather than replacing infrastructure as the routes to decarbonisation. It also flags Portugal's low circularity rate and the value of industry-academia collaboration.

Close to home

A quality barometer for the Oeste

NOVA IMS and IPQ have built a Quality Barometer combining technical indicators with residents' own perceptions of well-being, now being piloted in the Oeste region with Oeste CIM. The aim is a permanent national monitoring platform to support policy decisions.

Small wonders and gatherings

The gourd, turned into art

Maria Kabaça, created by Sónia Rodrigues, turns gourds — a traditional Portuguese crop — into one-off handmade pieces. The slow, entirely manual process links sustainability, craft and a little-recognised agricultural product.

Walking festival in the Neiva valley

Ponte de Lima hosts the Vale do Neiva Walking Festival on 26 and 27 September, part of WalkFest, with routes through Calvelo, Mato, Sandiães, Vilar das Lamas and Gaifar. Entry is free but limited to 50 walkers per route, with registrations from 31 August.

The 15-minute city comes to Guimarães

Urbanist Carlos Moreno, author of the "15-Minute City" concept, will speak at the 8th National Urban Cleaning Meeting in Guimarães from 8 to 10 September 2026. The event, themed "[De]Constructing the Future", is part of Guimarães European Green Capital 2026.

Good to know

Under the AYMURAY project, implemented by Oikos and funded by Instituto Camões, three schools in the municipality of Buesaco are gaining school gardens. They will supply fresh food for school meals and double as spaces for learning about sustainability.
