Un tour du monde sans escale en huit jours dans un avion avec l'hydrogène vert pour carburant: après Solar Impulse, Bertrand Piccard lance Climate Impulse, un nouveau projet pour promouvoir les technologies zéro émission et "montrer qu'il y a des solutions".Conçu en partenariat avec le chimiste belge Syensqo, qui s'est scindé en décembre de Solvay, l'avion aura un double fuselage avec le cockpit installé au milieu et 37 mètres d'envergure, moitié moins que Solar Impulse.

This Research Plan was prepared in response to a requirement in the joint explanatory statement accompanying Division B of the Consolidated Appropriations Act, 2022, directing the Office of Science and Technology Policy (OSTP), with support from the National Oceanic and Atmospheric Administration (NOAA), to provide a research plan for “solar and other rapid climate interventions.”

A major reason for the growth in the use of renewable energy is the fact that if a person looks at them narrowly enough--such as by using a model--wind and solar look to be useful. They don't burn fossil fuels, so it appears that they might be helpful to the environment. Energy modeling misses important points. I believe that profitability signals are much more important.

Mexico announced this Tuesday a set of measures to ban solar geoengineering experiments in the country, after a US startup began releasing sulfur particles into the atmosphere in the northern state of Baja California.

An all-electric future depends heavily on copper, and looming supply shortfalls could hamper nations’ goals of reaching net-zero emissions by 2050, according to a new report from S&P Global. Unless significant new supply becomes available, climate goals will be “short-circuited and remain out of reach,” the report says.

The federal effort could set the stage for more studies into the feasibility, benefits and risks of one of the more controversial means of combating climate change.

Morocco has become famous for its vast, world-leading solar arrays. But these mega-projects are just the start of the action on climate change that Morocco could be capable of delivering.

André Borschberg ne l’ignore pas, le chemin est encore long. Mais pour cet homme qui a réussi à faire le tour du monde aux côtés de Bertrand Piccard dans l’avion " solaire " Solar Impulse en 2015-2016, la hauteur de l’obstacle n’est pas vraiment un critère,

Rooftop solar panels are up to 79% cheaper than they were in 2010. These plummeting costs have made rooftop solar photovoltaics even more attractive to households and businesses who want to reduce their reliance on electricity grids while reducing their carbon footprints. But are there enough rooftop surfaces for this technology to generate affordable, low-carbon energy for everyone who needs it?

Cette pollution est due au probable dégazage sauvage d’un navire. « Les résidus sont répartis sur environ 500 mètres de long et 50 centimètres de large de manière discontinue », a précisé la préfecture de la Haute-Corse.
