“Future electricity needs for artificial intelligence (AI) are wildly uncertain—shaped by unproven concepts, disputed performance, limited trust, volatile markets, unpredictable adoption, and technical efficiency that quadruples roughly each year.” That warning comes from Amory Lovins, one of the legendary energy gurus of the 1970s and 1980s.

This audacious proposal comes in another of Trump’s avalanche of executive orders. On Friday (May 23) he… More Trump EOs push nuclear reprocessing, slam the NRC

By Kennedy Maize The most mature technology for storing energy to generate electricity when power supply is limited is water: pumped storage. The concept is straight forward: use power when it is plentiful to pump water to an elevated reservoir, then run the water downhill through turbines to make power when needed. It’s simple, it… More Getting pumped: Hydro storage promises and problems

By Kennedy Maize The on-again, off-again, Trump-again administration has reversed course and told a large, halted offshore wind project to resume construction. The Interior Department has told Norway’s Equinor to get back to work on its multibillion-dollar, 800-MW Empire 1 wind project some 14 miles off the shore of Long Island just a month after… More Wind wars: The Empire comes back

The transmission line would be in the footprint of the PJM regional… More FERC nixes $3 billion Mid-Atlantic transmission line

By Kennedy Maize Pennsylvania-based Air Products, the world’s largest producer of hydrogen, is moving away from basing much of its business on the a “clean” version of the first element on the periodic chart. As the elementary element, a building block of life, hydrogen has long been a promising path to a clean, powerful, adaptable… More Hydrogen: Long on promise but short on delivery

By Henry Sokolski With President Trump’s latest announcement that Iran’s centrifuges either will “blow up nicely in a deal” or “viciously without one,” the odds of a military strike against Iran’s nuclear program just shot up. This raises the question: if negotiations in Oman this fail, what might Israel or the United States target? Would they just hit the centrifuges?… More Guest Commentary: Nuclear Power Reactors and the Next War

By Kennedy Maize Wyoming Republican Gov. Mark Gordon wants to ship the Cowboy State’s plentiful coal to Japan, Taiwan, and South Korea, according to a recent account in Cowboy State Daily. Gordon recently returned from an Asian trip with what the statewide online news service calls “an idealistic vision.” Wyoming is the nation’s largest coal… More Coal pile: Wyo. coal exports? Miners push back on safety. Open or shut?

By Kennedy Maize One of the most enduring themes of the popular discussion of a man-made warming globe has been sea level rise as a result of the melting of ice from the planet’s two frigid poles. Former Vice President Al Gore’s 2006 film “An Inconvenient Truth” featured images of icebergs calving off the Antarctic… More Are melting glaciers and rising sea levels turning around?
