In many Chinese cities, streetlights are now powered by small vertical wind turbines. These devices spin even during cloudy, windless days, storing backup power to keep lights running at night.Unlike solar panels, these turbines can generate electricity in bad weather, making them more reliable for cities prone to smog or storms. They also reduce reliance on traditional grids and cut electricity costs for municipalities.It’s a small but powerful step toward smart, self-sustaining cities. Imagine an entire urban area where every lamp post generates its own clean energy — that’s the future China is piloting today.#technologysolutions
