For most of the modern era, capitalism justified itself through growth. Industrial societies converted vast amounts of fossil energy into production, wealth, and rising living standards. Roads, bridges, power grids, schools, and public institutions expanded alongside the economy. Inequality and exploitation remained deeply embedded in the system, but they were partly obscured by a broader story of material progress.
La cryptomonnaie a atteint son cours le plus bas depuis seize mois. François Villeroy de Galhau appelle à «fuir» les conseillers financiers qui le présentent comme un placement sûr.
Le "tout tout de suite" est la nouvelle norme qui régit nos comportements. Mais la riposte s'organise.
Much of today's sustainability discourse emphasizes efficiency, clean technologies, and smart systems, but largely underestimates fundamental physical constraints relating to energy-matter interactions. These constraints stem from the fact that Earth is a materially closed yet energetically open system, driven by the sustained but low power-density flux of solar radiation. This Perspective reframes sustainability within these axiomatic limits, integrating relevant timescales and orders of magnitude. We argue that fossil-fueled industrial metabolism is inherently incompatible with long-term viability, while post-fossil systems are surface-, materials-, and power-intensive. Long-term sustainability must therefore be defined not only by how much energy or material is used, but also by how it is used: favoring organic, carbon-based chemistry with limited reliance on purified metals, operating at low power density, and maintaining low throughput rates. Achieving this requires radical technological shifts toward l
... An “acid” test of our interpretation will be provided by the 2025 global temperature: unlike the 1997-98 and 2015-16 El Ninos, which were followed by global cooling of more than 0.3°C and 0.2°C, respectively, we expect global temperature in 2025 to remain near or above the 1.5°C level. Indeed, the 2025 might even set a new record despite the present weak La Nina. There are two independent reasons. First, the “new” climate forcing due to reduction of sulfate aerosols over the ocean remains in place, and, second, high climate sensitivity (~4.5°C for doubled CO2) implies that the warming from recently added forcings is still growing significantly.
Met de opwarming van de aarde stijgt ook de behoefte aan duurzame manieren om gebouwen te koelen. Onderzoekers van UCLA hebben nu een betaalbare én schaalbare techniek ontwikkeld om huizen en andere gebouwen in de zomer te koelen en in de winter te verwarmen, met behulp van alledaagse bouwmaterialen.
Hoe maken we in de toekomst nog medicijnen, bouwmaterialen, textiel of verpakkingsmaterialen als we geen fossiele grondstoffen meer gebruiken? Er bestaan al veel alternatieven, maar die kunnen vaak nog niet gebruikt worden. Gelukkig kunnen slimme computerprogramma’s ons helpen.
Bart De Wever schreef in zijn boek over woke dat het ‘onze cultuur vernietigt’ of ‘het water waarin we ons bevinden vergiftigt’. Maar als je vraagt wat woke precies is, blijft het antwoord meestal uit, schrijft sociaal-econoom Emmanuel O. Iyamu. Wat betekent woke nu echt?
De wereldwijde overschakeling op groene energie doet de vraag naar een aantal cruciale grondstoffen enorm stijgen. Europa is voor deze grondstoffen grotendeels afhankelijk van import uit andere landen. Met de Critical Raw Materials Act wil de EU die afhankelijkheid bijsturen.

Rystad Energy - A perfect and unavoidable storm: LNG supply crisis will make landfall in winter 2022
(09/05) - Press ReleasesA liquified natural gas (LNG) crisis is brewing for European countries dealing with energy insecurity in the wake of Russia’s invasion of Ukraine, as demand will outstrip supply by the end of this year, Rystad Energy research shows. Although soaring demand has spurred the greatest rush of new LNG projects worldwide in more than a decade, construction timelines mean material relief is unlikely only after 2024. Global LNG demand is expected to hit 436 million tonnes in 2022, outpacing the available supply of just 410 million tonnes. A perfect winter storm may be forming for Europe as the continent seeks to limit Russian gas flows. The supply imbalance and high prices will set the scene for the most bullish environment for LNG projects in more than a decade, although supply from these projects will only arrive and provide relief from after 2024 The European Union’s REPowerEU plan has set an ambitious target to reduce dependence on Russian gas by 66% within this year – an aim that will clash with the EU’s goal of
