Solar and Wind Are Reaching for the Last 90% of the US Power Market
An anonymous reader shares a report: Three decades ago, the U.S. passed an infinitesimal milestone: solar and wind power generated one-tenth of one percent of the country’s electricity. It took 18 years, until 2008, for solar and wind to reach 1% of U.S. electricity. It took 12 years for solar and wind to increase by another factor of 10. In 2020,…

Bimeronium: A new member of the topological spin textures family
Topological spin textures in magnetic systems are intriguing objects that exhibit exotic physics and have potential applications in information storage and processing. The most fundamental and exemplary topological spin texture is called the skyrmion, which is a nanoscale circular domain wall carrying a nonzero integer topological charge. The skyrmion texture in magnetic materials was theoretically predicted in the late 1980s, and…
The Empire State Building and Its Related Buildings Are Now Powered By Wind
The iconic Empire State Building that has crowned Midtown Manhattan since the early 1930s is now a game changer in American architecture in a different way: by becoming completely powered with renewable energy.
