Farmed kelp, seen here, has many industrial uses. Credit: Melissa Good | Alaska Sea Grant Kelp is plentiful in remote, coastal Alaska. Fuel is not. And it's expensive. Many isolated communities rely on diesel generators for energy because they are not connected to pipelines or the electrical grid. But diesel...

The performance of a device that can desalinate water using waste heat from solar cells, first developed by KAUST scientists in 2019, can be boosted by small changes in membrane design. Credit: KAUST Small changes in membrane design can have a large impact on the performance of a new technology...

Offices and homes are getting hotter, and the nights bring little respite from the heat. Against this backdrop, a significant increase in new cooling...

Graphical abstract. Credit: DOI: 10.1016/j.joule.2021.06.018 Renewable energy generation technologies such as solar, wind, and hydro continue to gain popularity worldwide. As more and more renewable generation enters the grid, the success of these clean technologies will increasingly rely on the development of long-duration energy storage solutions that support variability in...

The reactor is located in Taishan in China's southern Guangdong province, not far from Hong Kong. A reactor at a nuclear plant in southern China has been shut down because it is damaged, the operator said Friday, but it insisted there were no major safety issues. Chinese authorities last month...
