Current energy projections often envision an expansion of nuclear capacities to decarbonize future energy systems. However, this contrasts with the historic and current status of the nuclear industry, marked by techno-economic challenges for both light-water and non-light-water reactor technologies. Regardless, projections of strong nuclear growth have persisted since the 1970s. This paper investigates the “nuclear energy paradox” which shows the recurring divergence between historical projections and actual developments. A data compilation of long-term energy projections from international organizations such as the IAEA and the IEA as well as energy system models like GCAM and MESSAGE, as used in the IPCC, reveal a recurring pattern of high-growth projections for nuclear power. Such projections often rest on techno-economic assumptions such as substantial cost reductions. We propose the concept of nuclear imaginaries to show that these assumptions are embedded into techno-economic visions of nuclear power de

We are an international group of researchers and practitioners interested in the emerging fields of post-growth and ecological macroeconomics. Our aim is to advance economic theory, methodology and policy in order to adequately address some of the biggest challenges of our time: climate change, rising inequality, and financial instability.

Cultured meat is an emerging biotechnology that aims to produce meat from animal cell culture, rather than from the raising and slaughtering of livestock, on environmental and animal welfare grounds. The detailed understanding and accurate manipulation of cell biology are critical to the design of cultured meat bioprocesses. Recent years have seen significant interest in this field, with numerous scientific and commercial breakthroughs. Nevertheless, these technologies remain at a nascent stage, and myriad challenges remain, spanning the entire bioprocess. From a cell biological perspective, these include the identification of suitable starting cell types, tuning of proliferation and differentiation conditions, and optimization of cell–biomaterial interactions to create nutritious, enticing foods. Here, we discuss the key advances and outstanding challenges in cultured meat, with a particular focus on cell biology, and argue that solving the remaining bottlenecks in a cost-effective, scalable fashion will req

By putting in place climate change adaptation measures, NATO has an opportunity to both strengthen operational resilience and adapt to the impacts of climate change.

Le pic de la demande pétrolière pourrait être atteint avant la fin de la décennie, estime l’AIE. Cette année, la production atteindra malheureusement un record autour de 102 millions de barils/jour.

Dans son rapport remis le 22 mai à la Première ministre, l'économiste Jean Pisani-Ferry évalue les impacts macroéconomiques de l’action pour le climat, notamment la transition énergétique. Et tout n’est pas si noir.

As it confronts environmental, geopolitical and economic shocks, Europe is in a position to show the way to climate neutrality and social equality, top advisor says.

Création d’une délégation interministérielle, d’un observatoire, d’un fonds de financement: le gouvernement creuse le sujet de l’approvisionnement en minerais et métaux stratégiques. Mais le retour massif de l’industrie minière dans l’Hexagone reste tabou.

Depuis les airs, l'énorme trou de mine d'un kilomètre de diamètre creusé dans la roche ocre contraste avec l'épaisse végétation environnante. L'activité du site, qui a débuté en février 2019, pourrait cependant s'arrêter d'ici quelques jours... Le président du Panama, Laurentino Cortizo, a posé un ultimatum à la société cotée à Toronto pour qu'elle accepte un nouveau contrat de concession, qui multiplierait par dix les taxes dues au pays pour pouvoir exploiter la mine.
