Solar-powered adsorption cooling systems (SACS) have gained traction as a renewable energy technology that could provide clean power for air conditioning and refrigeration while significantly reducing the load on the electric grid. But these systems lack energy efficiency. In the Journal of Renewable and Sustainable Energy, by AIP Publishing, researchers from Anna […]
A metal foam could underpin a low-cost method for generating carbon-free fuels, researchers from KAUST have shown. The team seamlessly coated the foam with iron and cobalt nanomaterials to create a highly active electrode for a device that splits water molecules to release oxygen and hydrogen, a potential green fuel. Due to […]
Across social media, internet forums and some climate science denier blogs, there has been furious cutting-and-pasting of chunks of common text attacking the environmental credentials of electric vehicles, solar panels and wind turbines. About 200 tonnes of the “Earth’s crust” needs to be mined for each electric vehicle battery, and 11 tonnes of brine are […]
Grid upgrades, renewable energy on horizon Published March 30, 2022 by Elizabeth Cooper This is a pivotal time for electric utilities such as Dominion Energy, which are upgrading power grids and systems to accommodate renewable energy sources such as wind and solar. Photo by Mark Rhodes Virginia’s largest electric utilities are deploying an array of […]
In the future, decarbonized societies that use internet of things (IoT) devices will become commonplace. But to achieve this, we need to first realize highly efficient and stable sources of renewable energy. Solar cells are considered a promising option, but their electrical contacts suffer from a ‘tradeoff’ relationship between surface passivation and conductivity. Recently, […]
The Biden administration yesterday announced a study on whether to impose import duties on solar panels and key equipment, which angered proponents, saying it could slow industry growth enough to counter climate targets. The study, which could take a year to complete, was prompted by a petition by US solar cell maker Auxin Solar Inc. […]
