Today, solar electricity comes from nearly a million homes, schools, hospitals, supermarkets, factories and fields. How do you track a million invisible energy creators?

Ammonia, the primary ingredient in nitrogen-based fertilizers, has helped feed the world since World War I.

Gallium nitride, a semiconductor that revolutionized energy-efficient LED lighting, could also transform electronics and wireless communication, thanks to a discovery made by Cornell researchers.

Rooftop solar panels are a great way for people to invest in renewable energy while saving money on electricity.

Researchers at Stanford University and the Department of Energy’s SLAC National Accelerator Laboratory say they have found the first, long-sought proof that a decades-old scientific model of material behavior can be used to simulate and understand high-temperature superconductivity ­– an important step toward producing and controlling this puzzling phenomenon at will.

Dartmouth's Arthur L. Irving Institute for Energy and Society and Thayer School of Engineering will collaborate with the U.S. Army Corps of Engineers' Cold Regions Research and Engineering Laboratory (CRREL) to assess ways to improve energy services, delivery, storage, and mobility for military bases in the Arctic.

Last year, Princeton researchers identified a disturbing security flaw in which hackers could someday exploit internet-connected appliances to wreak havoc on the electrical grid.

People are less motivated to take actions if its outcome is uncertain, and this could be true for climate-related issues. 

This week NOAA added a new model to its suite of tools designed to help the nation deal with space weather events.

The wind is always blowing somewhere, but deciding where to locate a wind farm is a bit more complicated than holding up a wet finger.
