WASHINGTON D.C. – A new report from the Department of Obscure Energy Metrics (DOEM) reveals that the United States experienced a staggering 3,000% increase in grid-scale energy storage last year, primarily fueled by what analysts are calling the 'Great Couch Cushion Cache.' The surge, occurring despite sustained political rhetoric against renewable energy, has left experts scratching their heads.

According to Dr. Penelope 'Penny' Saver, lead researcher at the Institute for Found Objects in Power Generation, the data indicates a nationwide phenomenon of citizens unearthing vast quantities of previously lost or forgotten batteries. 'We're talking about everything from single AA batteries destined for a long-dead remote control to entire packs of D-cells that rolled under the fridge in '98,' Dr. Saver explained, adjusting her spectacles. 'The sheer volume is frankly terrifying, yet also incredibly efficient.'

Critics of renewable energy have been notably silent on the development, with one anonymous source from the 'Coal is Cool' think tank reportedly stating, 'Well, if it's not wind, and it's not solar, and it's not… well, whatever those other things are… then I guess it’s fine? As long as it’s not too… green.'

Meanwhile, the National Association of Sofa Manufacturers (NASM) has issued a statement urging citizens to 'check their upholstery for potential energy assets' before discarding old furniture. 'We estimate billions of joules are still trapped in forgotten crevices,' said Chet 'The Cushion' Chesterfield, NASM's Chief Ergonomic Power Consultant. 'It's a goldmine, or rather, a nickel-cadmium mine, right under our noses.'
