Un article que he escrit reflexionant sobre com la transició energètica hauria d'incloure una reflexió sobre futurs socials alternatius i com l'energia, més enllà del caire evidentment tecnològic, és alhora profundament política

I’m really surprised this isn’t bigger news. Just under 10 million people live in Tehran. Where can they go? Where else in Iran will have enough water? This will undoubtedly strain the country’s and the region’s politics, finances and governance capacity.
'Iran’s capital must be moved because the country “no longer has a choice,” President Masoud Pezeshkian said on Thursday in remarks carried by state media, warning that severe ecological strain has made Tehran impossible to sustain'

I've been looking for a piece of furniture for years now. Something that is nice and well-crafted, built to last a lifetime. In my extensive research visiting shops of all prices, I feel everything feels fragile, as if it could fall apart at any moment.

I think that a building with the best temperature energy efficiency but within a bad urban form (to which the building itself is contributing), shouldn't get a good energy certification.

Like this local knowledge should be one step of policy and also of some science. But now many policies and strategies are tested/modelled/explored by scientists and we should be giving some fundamental idea of what could be discussed in local policymaking and what is not possible, right?

I'm not going to know how to express this well but I don't like policy advice that focuses more on ideas like 'local knowledge' and 'co-production' and not specific solutions.

Yo no entiendo de cronobiología pero en el Mediterráneo solo hay temperatura agradable (fresquito) muy temprano por la mañana en verano, y es justo donde más raro quedaría el horario de invierno de amanecer en verano. Ahora mismo es lo único que me preocupa de todo este tinglado y no se habla

Hi ha una idea que és la base de molts debats actuals (inclosos el canvi climàtic, l'educació o el català): per fer aprendre o actuar hem de ser seductors o hem de ser exigents?

Transparency in turbine composition is still a challenge due to the opacity of industry, but WindTrace offers a flexible, open approach to have informed estimates to bills of materials and life cycle impacts.

Transparency in turbine composition is still a challenge due to the opacity of industry, but WindTrace offers a flexible, open approach to have informed estimates to bills of materials and life cycle impacts.
We compared WindTrace to Ecoinvent, ran sensitivity analyses, and explored how different design choices affect climate change impacts per MW and kWh.

We compared WindTrace to Ecoinvent, ran sensitivity analyses, and explored how different design choices affect climate change impacts per MW and kWh.
In this new paper, we present WindTrace: a parametric Life Cycle Inventory model for onshore wind turbines built in Brightway, led by Miquel Sierra Montoya (@icta-uab.bsky.social). It estimates bills of materials and environmental impacts based on turbine and farm parameters.

Turbine composition is largely intransparent and existing Life Cycle Inventory datasets rely on outdated wind turbine models such as the 4.5MW cement tower in Ecoinvent, which don't reflect currently evolving and growing turbines and can overestimate environmental impacts.

Missed Raúl Velasco’s webinar last Tuesday?
You can now watch it in full on YouTube! 🎥
In this REAL project talk, he explores how the Global North’s growth relies on massive amounts of unpaid care work—mostly by women—appropriated through unequal exchange.

(clarification: I've known about this since I started working with value added, but this sounds like accounting engineering to ensure GDP growth)

(clarification: I've known about this since I started working with value added, but this sounds like accounting engineering to ensure GDP growth)
As a person who has previously worked with machines and production processes, value added is still a mistery (despite 8 years in ecological economics academia) and this imputed rent for home owners accounting for value added still sounds very weird to me. en.wikipedia.org/wiki/Imputed...
