When James Prescott Joule lent his name to a unit of energy, he could not have foreseen today’s alarming calculations

The activist and author of Here Comes the Sun discusses rapid advances in solar and wind power and how the US ceded leadership in the sector to its main rival

87%. That’s how much the emissions of NVIDIA (worth 5 trillion dollars) increased in 2024, as an article from TruthDig is one of the only sources in the world to point out. This means it became the world’s most valuable company by answering soaring demand for AI… whilst doubling its carbon footprint. Not to mention water: Samsung’s next ‘mega-cluster’ of GPU fabs will consume half of Seoul’s water, says the same article.

The planet is nearing dangerous limits. Yet progress on clean energy shows what’s possible. With political will, cooperation can still avert the worst of the climate crisis

Taking a closer look at AI’s supposed energy apocalypse

UN says a global ‘backlash’ against climate action is being stoked by fossil fuel companies

A new record high, but is there light at the end of the tunnel?

A new climate case was filed this week. Multnomah County, the Oregon county that includes Portland, filed suit against several oil majors for their role in exacerbating the climate change that led to the county's "heat dome" in June 2021, which killed 69 people. But the case doesn't just place

L'Allemagne s'est fixé l'objectif ambitieux d'atteindre la neutralité carbone d'ici à 2045, en misant essentiellement sur le développement des énergies renouvelables et des gains d'efficacité énergétique. Dans l'analyse ci-après (en anglais) publiée le 30 juin par l'Oxford Institute for Energy Studies, Ralf Dickel(1) « montre pourquoi, pour l'Allemagne, une approche entièrement renouvelable et principalement électrique pour atteindre zéro émission nette d'ici 2045 ne fonctionnera pas, et ne permettra pas de maintenir un approvisionnement énergétique fiable ». Il souligne à ce titre le rôle essentiel du captage et de la séquestration du CO2 dans le cas allemand. L'auteur s'interroge en particulier sur les possibilités et infrastructures nécessaires pour exporter le CO2 capté sur le territoire allemand vers la Norvège.
