After that, the price stops making sense. So China built an alternative out of thin air: the world's largest compressed air battery, a salt cavern energy storage system with no lithium and no fuel burned to get the power back out. The pitch is that it beats lithium at long duration energy storage. But run the math on how long it actually lasts, and the answer comes out to 4 hours too, exactly where lithium already wins. So is China's giant air battery actually solving the long-duration problem? Or is it just an expensive peaker plant that happens to run on air?

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?

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?
