Thermoelectric technologies can help power a zero-carbon future

Human societies produce huge amounts of excess heat. Turning it into electricity could play a key role in achieving a net-zero society.

Scientists have been researching superconductors for over a century, but they have yet to find one that works at room temperature − 3 essential reads

Claims about the discovery of a coveted room-temperature superconductor peppered the news in 2023. We pulled three stories from our archives on what superconductivity is and why scientists study it.

Maine voters don’t like their electric utilities, but they balked at paying billions to buy them out

Power companies can be publicly or privately owned and may report to corporate boards, local governments or co-op members. But there’s no one best way to deliver electricity reliably and affordably.

What is a virtual power plant? An energy expert explains

Some power plants don’t have massive smokestacks or cooling towers – or even a central site.

Superconductivity at room temperature remains elusive a century after a Nobel went to the scientist who demonstrated it below -450 degrees Fahrenheit

Superconductivity may sound like science fiction, but the first experiments to achieve it were conducted over a century ago. Heike Kamerlingh Onnes, credited with the discovery, won a Nobel Prize in 1913.
