An almost limitless supply of fresh water exists in the form of water vapor above Earth’s oceans, yet remains untapped, researchers said. 

Health benefits of using wind energy instead of fossil fuels could quadruple if the most polluting power plants are selected for dialing down, new study finds.

Cooling accounts for about 15 percent of global energy consumption. Conventional clear windows allow the sun to heat up interior spaces, which energy-guzzling air-conditioners must then cool down. 

A new research project at Aarhus University aims to develop intelligent, autonomous drones that can fly out to small and large wind farms and scan, detect and report any icing on the blades of the turbines.

Scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) have demonstrated a new technique, modeled after a metabolic process found in some bacteria, for converting carbon dioxide (CO2) into liquid acetate, a key ingredient in “liquid sunlight” or solar fuels produced through artificial photosynthesis.

Aquifer thermal energy storage systems can largely contribute to climate-friendly heating and cooling of buildings: Heated water is stored in the underground and pumped up, if needed. 

First, the bad news: Nothing is free. Moving the world energy system away from fossil fuels and into renewable sources will generate carbon emissions by itself, as construction of wind turbines, solar panels and other new infrastructure consumes energy—some of it necessarily coming from the fossil fuels we are trying to get rid of. 

The average emissions associated with a low-carbon energy transition amount to 195 gigatonnes of CO2, which equals approximately 0.1 °C of additional global warming.

Research demonstrates pathway to sustainably produce biojet fuel domestically, meet country’s growing aviation fuel demand.

The French Senate has passed legislation requiring parking lots with at least 80 spaces be covered in solar panels.
