See-through solar cells harvest some wavelengths of light to make electricity, while passing through the red and blue wavelengths that plants need. In a new agrivoltaics experiment, broccoli yields held steady.
Data centers need millions of gallons of water a day. Oil and gas industries produce more wastewater than that. Connecting them using today’s desalination technologies makes sense.
HVAC systems burn energy pulling moisture out of the air. This wallpaper does the opposite: It cut humidity while generating electricity.
In a first, researchers realistically calculated how solar farms in the Gobi Desert improve air quality in northern Chinese cities
Flying behind commercial jets, a team pinpointed the exact combination of fuel and engine technology that cuts both soot and the contrails warming the planet.
Scientists expected their artificial floating wetland to help only after cleaning the water. Instead, greenhouse gas emissions dropped months earlier, and nobody is sure exactly why.
Building standards treat all concrete the same, hindering the use of greener concrete, but climate conditions play a much bigger role in determining a structure’s durability
Retired EV batteries and clean-energy demand are on opposite sides of China. Reuniting them could be one of decarbonisation’s cheapest wins.
Europe bet on sorting discipline, America bet on convenience, and the climate math is still being settled.
