Using carbon dioxide instead of oxygen in a key point in creating perovskite solar cells could remove a stumbling block to making them more widespread.

Researchers have overcome a challenge that could pave the way for getting "blue energy" from sea water, with zero carbon emissions.

Researchers are finding ways to boost the amount of power that concentrated solar power plants generate. The work could make them more widespread.

A "molecular glue" strengthens a key weak point in perovskite solar cells. The advance makes them tougher, more efficient, and more reliable.

India's ambitious target of 450 gigawatts of renewable energy capacity by 2030 could go even further, say three economists.

Lettuce grows well in greenhouses made of clear solar panels. "We were a little surprised—there was no real reduction in plant growth or health."

When power companies make sustainably produced electricity their default option, consumers are more likely to choose it, a new study shows.

Researchers have created a new solution for generating solar power. The new "windows" could create energy from light from indoors and outdoors.

Wind and solar power in California isn't as beneficial to the environment as renewable energy in Florida, researchers say. Here's why and why it matters.
