How My Home Battery Really Performed (2 Years Later). Start your 7-day free trial + unlock 4 extra months of Surfshark VPN — head to https://surfshark.com/undecided or use code UNDECIDED at checkout! My January electric bill came to $336, even with solar on the roof and 20 kWh of home battery storage on the garage wall. After 12 months of utility bills and circuit-level data, the solar battery math got weird. The panels saved money. The battery cost about $207 a year, thanks to net metering, round-trip losses, and the way Massachusetts credits rooftop solar. But I would still buy it again. So is a home battery actually worth it for resilience? Or is the whole thing just an expensive backup plan?

The world threw out 62 million tonnes of electronics in 2022, and less than a quarter of it reached proper recycling. The copper in that pile was worth about $19 billion. Demand climbs to roughly 33 million tonnes by 2035, while mined supply peaks in the late 2020s and then falls below 19 million. A new mine takes about 17 years to open, so digging can't close the gap in time. Recycled copper covered 18% of demand in 2015, and today it covers under 17%. The EU's Circular Economy Act aims to double Europe's rate by 2030, and UNEP argues recycling only works alongside using less copper in the first place. So what's the oldest dead phone in your drawer?

Why The US Sucks at Solar. Take your personal data back with Incogni! Use code UNDECIDED at the link below and get 60% off an annual plan: http://incogni.com/undecided About one in three Australian homes have rooftop solar. In America, it's less than one in ten, even though half the country sits under the same sun. The real story is the bill. The rooftop solar cost here runs up to seven times higher than in Australia, once tariffs, tax credits, and solar permitting pile on top of the price tag. Australia is adding home solar batteries at a blistering pace, and its lead keeps growing. So is Australia actually better at cutting paperwork? Or is America's red tape just costing you thousands?

Why The Biggest Battery Company Is Betting On Lithium Air. Subscribe to IEEE Spectrum Magazine and get 20% off: https://spectrum.ieee.org/undecided And check out @ieeespectrum on Youtube. CATL, the world's biggest battery maker, just named its bet for what comes after solid-state batteries: lithium air. Headlines claim this battery stores as much energy as gasoline. This lithium air battery breathes, pulling oxygen straight from the surrounding air instead of packing in heavy metal cathodes. Scientists say the design could push EVs past 1,000 miles on a single charge, and a startup is already chasing it for drones and aircraft. So is this air-breathing battery actually as close to gasoline-level energy as CATL claims? Or is that number just a headline that outran the lab?
Edit: we're aware there's a slight issue with the audio, we're taking a look at the cause and apologize for the inconvenience!

Every winter, it burns fuel to make that heat all over again. What if you could bank July's heat underground, then pull it back out in January? Aquifer thermal energy storage does exactly that. It turns the groundwater under your feet into an underground thermal battery, and the Netherlands has been running ATES this way for more than 30 years. The US Department of Energy proved the idea worked here decades ago, then let it go quiet. So is ATES actually the cheapest way to heat and cool a whole city block? Or is the Dutch head start too big for us to copy?

You're hearing this through speakers run by magnets, and your smartphone might hide another 18 of them. Most of us ignore them until the supply chain snaps. China's rare earth export controls did exactly that. Now there's a new iron nitride magnet, made from just iron and nitrogen, two of the most abundant elements on Earth, and Niron Magnetics has broken ground on a factory to build it at scale. A second rare earth free magnet gets more stubborn as it heats up. So are these magnets ready to replace neodymium magnets? Or is this just proof of how hard rare earths are to replace?

Right? Researchers in Australia just tested one that flips that rule completely. The larger they built it, the faster it charged. It runs on quantum effects, and the very first version charged with light from a laser, no cord required. Scientists call the ultra fast charging trick superabsorption, and it hints at energy storage that could one day power your phone or car. So is this quantum battery actually the future of charging? Or is it just a lab curiosity that fizzles out in nanoseconds?

What I Found Behind Disney World's Hidden Systems. Take your personal data back with Incogni! Use code UNDECIDED at the link below and get 60% off an annual plan: http://incogni.com/undecided I got an exclusive backstage look at Disney World expecting a polished sustainability tour. Then I watched old beer bottles get ground into sand, stood in an overgrown solar field built for native bees, and traced food scraps through a closed loop recycling system that once helped power the parks. Disney World handles this like a small city, with 50 million visitors a year and decades of infrastructure behind it. So is Disney’s sustainability actually a model other companies can learn from? Or is the whole thing just too Disney-sized to copy?
