Africa and Asia have 85 percent of the world’s affordable hydropower, and it is possible to develop the resource while treading lightly, a new analysis shows
Engineers have made a device one-hundredth the size of previous solar-to-hydrogen devices that is over three times more efficient
In a promising step toward a more sustainable, circular economy, chemists have developed a reactor that turns two of the world’s most problematic waste streams into useful products
By combining a salt and a solvent—both cheap and abundant—engineers developed a new refrigeration system that uses less energy and emits no greenhouse gases
With a simple one-step treatment that changes the nanostructure of wood, researchers have boosted the electricity it produces when wet--enough to light up LEDs and even laptops
Desalinating the oceans is energy-hungry business, so why not economically and sustainably capture the water vapor floating above the oceans with cruise ship-sized structures?
Simple energy harvester made with store-bought double-sided tape can light up a string of LEDs, hinting at bright future for low-cost sustainable power
Plastic boards used in electronic devices and batteries are near-impossible to recycle, so researchers devised a sustainable alternative made from biodegradable mushroom skin
Engineers used artificial intelligence and advanced computing to design a transparent coating that blocks the sun's heat and sends it from the window straight into outer space
