    "text": "✍️ New article: Battery costs have declined by 99% in the last three decades, making electrified transport a reality—\n\nOver 20 million electric cars were sold globally in 2025 — some for as little as $10,000. Even just two decades ago, that would have been impossible.\n\nThe reason it's possible now? Batteries have gotten *much* cheaper.\n\nIn 1991, lithium-ion battery cells cost around $9,200 per kilowatt-hour. By 2024, that had fallen to just $78 — a decline of more than 99%. You can see this in the chart.\n\nTo put that in perspective: the battery cells in a standard electric car today cost around $5,000. In 1991, those same cells would have cost nearly $600,000.\n\nThere was no single breakthrough behind this. Batteries follow a “learning curve”: as cumulative production grows, thousands of small improvements in chemistry, manufacturing, and supply chains drive prices down.\n\nSince 1998, every time global cumulative battery production doubled, the price dropped by roughly 19%.\n\nEarly progress was driven by consumer electronics — phones and laptops — before the technology became viable for cars, buses, and larger energy storage.\n\nEnergy density has also more than tripled since the 1990s, meaning batteries can now store far more energy for their volume.\n\nThe half-a-million-dollar battery was never going to transform transport. The $5,000 battery is.",
