When #BadBunny climbed utility poles at last night's #SuperBowl halftime show, his point came across loud and clear: Puerto Rico's power grid is crumbling, and the U.S. isn't doing enough about it. Here's what's happening in Puerto Rico. Photo: Kathryn Riley/AP. spectrum.ieee.org/puerto-rico-...

Can we collect solar energy in space and beam the power back to Earth? A new startup coming out of stealth mode demonstrates how it would go about it by wirelessly beaming near-infrared waves from a moving aircraft. #energysky spectrum.ieee.org/wireless-pow...

This giant dome in Sardinia is filled with CO2 and serves an eco-friendly purpose: to store large amounts of excess renewable energy. In 2026, more of these "CO2 Batteries" will start popping up on multiple continents. Spectrum energy editor @emwaltz.bsky.social visited and explains how it works.

The US is planning its largest nuclear power expansion since the 1970s with an $80 billion investment in AP1000 reactors. Will the program be dogged by the same cost overruns and delays of past AP1000 construction? @edcrooks.bsky.social with @woodmac.com explains.

Are virtual power plants just as good as conventional ones at balancing electricity supply and demand? A new Turing-like test helps grid operators judge. @spectrum.ieee.org spectrum.ieee.org/virtual-powe...

England's grid can't handle all the power flowing south from Scotland's wind farms, but this nifty tech will help. It's called a SmartValve, and moves more power without having to build new transmission lines. @spectrum.ieee.org @peter.fairley.ca spectrum.ieee.org/grid-congest...

Fire-prone counterfeit li-ion batteries are infiltrating the market. Here's how to spot one. By @andrewmoseman.bsky.social with special thanks to experts at @ulresearchinst.bsky.social and University of Maryland. spectrum.ieee.org/counterfeit-...

Tonight at 5pm EST! Nuclear battery expert Jake Blanchard will make himself available for an Ask-Me-Anything session on Reddit. Bring your questions! Like: Can we power our phones with nuclear batteries so that we never have to charge them? @spectrum.ieee.org www.reddit.com/r/nuclear/co...

A raft of companies are developing nuclear batteries that can power devices for decades. Is that a good thing? Will anyone want to buy them? And will anyone be paying attention to where this radioactive waste ends up in 50 or 100 years? @spectrum.ieee.org spectrum.ieee.org/nuclear-batt...

Cuba's power grid is nearing total failure; how did it get this bad? Cuban economist Ricardo Torres explains in @spectrum.ieee.org spectrum.ieee.org/cuba-energy-...

The new, hefty tariffs on solar will change industry; one potential winner: next-generation perovskite solar cells, to which the tariffs don't apply. Ossila scientist Mary O'Kane explains: spectrum.ieee.org/perovskite-s...

Ford is welcoming back a rock-star engine designer after pushing him out four years ago in favor of EV experts. Why does the company need him back? Lem Yueng tells his story: spectrum.ieee.org/ford-powertr...

The XPrize in carbon removal went to a surprising choice: enhanced rock weathering startup Mati Carbon, which received $50 million. Noticeably absent from the top winners: direct air capture and ocean carbon removal strategies. spectrum.ieee.org/xprize-carbo...

What does Trump's $500 billion Stargate AI initiative mean for the U.S. grid? We asked experts to weigh in. #EnergySky With @costasamaras.com spectrum.ieee.org/stargate

China is building a nuclear reactor that will run on fuel bred from thorium, which could be sourced from rare earth waste. Here's what we found out about this new molten-salt reactor in the Gobi Desert. #EnergySky spectrum.ieee.org/chinas-thori...

These startups are geoengineering the sea to capture and store more CO2 from the air. I visited a few Pacific Ocean operations for this deep dive into marine carbon tech. spectrum.ieee.org/ocean-carbon...
