Moving from coal to natural gas could help save a lot of water, but moving to renewables would use just a fraction of the water we use today for power.

Solar cells that can be used on a curved surface like the body of a car may be one step closer to reality thanks to a new discovery about conductivity.

Growing crops under the shade of solar panels, also called agrivoltaics, could boost food production, use less water, and make solar panels more efficient.

A new water harvester can get pure drinking water from the air, even in some of the driest desert environments on the planet.

With more investment, better energy storage for wind and solar power could prevent extra energy from being wasted and cut greenhouse gas emissions.

A new battery technology can capture "blue energy" from places where saltwater and freshwater mix and constantly keep itself charged.

New technology could boost the efficiency of solar power systems by converting waste heat into light.

A change on wind farms can boost the amount of power they produce and make production more consistent—but it's a bit counterintuitive.

A new rooftop solar refinery pulls in CO2 and light and turns them into a liquid fuel.
