"Imagine an autonomous drone that powers itself with a solar array atop its wing that is 15 times thinner than a piece of paper. That's the promise..."

"Snow-phobic coatings, if we can demonstrate their long-term efficacy, will make solar power more reliable and more affordable in snowy regions..."

Researchers have boosted the efficiency of solar cells made from semiconducting perovskites while retaining their ability to stand up to the environment.

Electric vehicles could send energy back to power grids while they're parked, researchers report. The process could also save owners money each year.

Calculations indicate that passive solar systems could offer a third of the heat needed to warm homes in the United States.

Transparent solar cells that are highly efficient and last up to 30 years could get us one step closer to windows that generate power.

It's not clear if new carbon nanotube fibers in fabric will lead to a solar panel you can put in the washing machine, but the tech has potential.

When, where, and how electric delivery fleet vehicles are charged can greatly affect their potential to reduce greenhouse gas emissions, researchers report.

When a power system combines energy storage and solar power generation, the end result is greater than the sum of its parts, according to a new study.
