A new way to produce perovskite solar cells using inorganic ingredients limits their defects and lets them last for months.

Carbon capture technologies could actually produce more carbon dioxide than they suck up. Focusing on renewables is a better solution, researchers say.

Using solar power technology solves a lot of the problems with the fluorescent dyes used to detect and attack cancer cells.

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.
