The solar project, southeast of Seville, will power Amazon Web Services data centers and logistics locations, and is expected to start generating next year. The company has launched its Climate Pledge with the aim of complying with the Paris Agreement 10 years early by neutralizing carbon emissions by 2040, and of operating with 80% renewable energy by 2024 and 100% renewable energy by 2030.

Scientists at the United States’ Argonne National Laboratory worked with a class of electrolyte materials they say could greatly improve the performance of lithium-sulfur batteries. The group has devised a selection rule which it says will help researchers select the most suitable electrolyte materials for different battery systems.

Researchers in Chicago have developed a world first fully rechargeable lithium-carbon dioxide battery, an achievement they claim could pave the way for the use of the greenhouse gas in advanced energy storage systems.

Researchers from the U.S. Department of Energy’s Argonne National Laboratory, working with Cambridge University, programmed a ‘supercomputer’ to narrow down a list of almost 10,000 materials with the potential to be used in dye-sensitized solar cells to just five that fit their parameters for high performance, low cost and low environmental impact.

Chicago may be the largest city in the U.S. to commit to 100% renewable energy and has set a 2035 target date. The famous city’s long association with nuclear power says a lot about the future of clean energy Statesside.

While U.S. senators Ed Markey and Alexandria Ocasio-Cortez introduce a resolution for a clean energy package, legislation has been tabled in six states aiming to implement 80-100% clean energy by 2050 or earlier.
