Close to the sun, the solar wind, a steady stream of charged particles, accelerates until it cannot turn back. During a record pass about 3.8 million miles above the surface, Parker Solar Probe ...

By 2050, offshore wind power capacity in the North Sea is set to increase more than tenfold. Researchers at the Helmholtz Center Hereon have analyzed the long-term overall impact of this large number ...

Look up in the sky, it's a bird, it's a plane, it's ... a 20,000 cubic-meter power-generating airship, floating 6,560 ft (2,000 meters) above the ground. Introducing the S2000 stratospheric airborne ...

The simplest definition of wind is air in motion. Wind is generated by uneven pressure in the atmosphere, which is caused by uneven heating by the Sun, land, and oceans. The air closest to the ground ...

For more than a century, engineers have chased new ways to turn the planet’s natural motions into usable power, from tides to geothermal heat. Now a small group of physicists says Earth’s own magnetic ...

Clean electricity from the sun and wind has expanded at record speed, but the next phase of decarbonization will be defined by something different: a source that can run almost all the time, in almost ...
