Recovery of vegetation on plugged and abandoned oil and gas well sites on the Colorado Plateau is influenced by time, moisture, nonnative plants and the type of plant community that was originally in place before well sites were constructed, according to a recently published study by the U.S. Geological Survey.

Scientists have created flags that can generate electrical energy using wind and solar power.

Green plants capture light that spans the visible solar spectrum, and while a broad spectral range is required for sufficient absorption, the process requires energy to be funneled rapidly and efficiently downhill to drive charge separation and water splitting.

Perovskites — a broad category of compounds that share a certain crystal structure — have attracted a great deal of attention as potential new solar-cell materials because of their low cost, flexibility, and relatively easy manufacturing process.

Scientists have discovered a new process to make polymers out of sulfur which could provide a way of making plastic that is less harmful to the environment.

Phosphate is a key element in many processes in the body and essential for global food production.

Hydrogen, the second-tiniest of all atoms, can penetrate right into the crystal structure of a solid metal.

As the solar industry has grown, so have some of its inefficiencies.

Strategies for growing biomass for fuel can have ecological and environmental benefits.

A new distribution system designed by researchers at the University of Waterloo would reduce electricity prices by more than five per cent while also improving service reliability.
