Tudianzi Village, a remote mountain hamlet nestled 1,200 meters above sea level in central China’s Hubei Province, is rapidly becoming a beacon of sustainable development. Once a forgotten stop along the ancient Tea Horse Road, the Tujia ethnic community has emerged as a national model of rural revitalisation through clean energy innovation, achieving 24/7 zero-carbon operations powered entirely by renewable energy.
During this April’s Pear Blossom Festival, over 50,000 visitors flocked to the village in just two days, drawn by more than the stunning terraced blossoms and misty vistas of the Wu Gorge. Tourists were amazed by solar-powered benches that wirelessly charge phones, solar-storage integrated street lights illuminating the rural pathways, and all-electric kitchens dishing up traditional Tujia cuisine.
“The table actually charges my phone wirelessly!” exclaimed tourist Tan, marvelling at the solar-powered amenities dotting the village’s eco-tourism corridor.
Located in Badong County, within the Enshi Tujia and Miao Autonomous Prefecture, Tudianzi has undergone a dramatic transformation since 2023 when State Grid Hubei Electric Power launched a flagship green energy pilot project. The initiative aimed to address chronic power outages and unsustainable biomass dependency, replacing firewood and outdated electrical infrastructure with a comprehensive low-carbon energy system.
“Whenever thunderstorms struck, the entire village would go dark,” recalled 75-year-old Hu De’an, reflecting on the past when firewood was the only dependable energy source. “Now, our homes are bright and smoke-free.”
At the core of this transformation lies a network of solar panels installed on rooftops, public corridors, and even on livestock enclosures, generating up to 1,800 kW. The village also features biogas systems converting pig manure and kitchen waste into electricity and fertiliser, creating a circular “waste-to-energy” ecosystem.
One standout example is the black pig breeding base, producing over 4,000 hogs annually. Its integration with a 30-kW biogas plant and 80-cubic-meter gas storage ensures a steady supply of clean energy, even at night.
“Biogas powers local homes and farms, while the byproducts enrich our fields,” said Su Lei, senior engineer at State Grid Hubei Electric Power Research Institute. “It’s clean, efficient, and completely off-grid capable.”
Local farmers like Feng Cailong are already reaping the benefits. “We used to spend over 40,000 yuan annually to dispose of pig waste. Now, the biogas plant handles it, and we save an additional 60,000 yuan on electricity and fertiliser,” he reported.
Tudianzi’s renewable energy output has soared to 1.44 million kWh annually, up from just 186,000 kWh in 2022. In 2024 alone, the village’s power usage surged by 188%, fuelled by its growing population, tourism, and agricultural modernisation. The resulting carbon reductions are equally impressive, saving 472 tons of standard coal and cutting CO₂ emissions by over 1,436 tons a year.
“Our total installed green energy capacity has reached 1,871 kW,” noted Yang Lin, a local development official. “Not only do we meet all local electricity needs, but we also export surplus energy to the broader grid.”
Backed by China’s 2020 “dual carbon” goals to peak emissions by 2030 and achieve carbon neutrality by 2060, Tudianzi’s green leap forward demonstrates how technology, tradition, and policy can converge to build a sustainable future, even in the most remote corners of the country.
As solar panels gleam above rustic wooden homes and tourists stroll flower-laden paths powered by clean electricity, Tudianzi stands as a shining example of how China’s rural heartland is embracing its green destiny one ray of sunlight at a time.
