Picture this: The same civilization that built a 13,000-mile stone guardian against northern invasions is now engineering barriers against climate change. The Great Wall Series Wincle Energy initiative represents China's latest fusion of historical symbolism and cutting-edge energy technology – think solar panels dancing along ancient battlements and wind turbines whispering secrets to Ming Dynasty watchtowers.
This isn't your grandfather's energy project. The Wincle framework combines:
Remember that viral video of a drone filming sunset over the Wall while charging via built-in solar tiles? That's wall energy in action – turning historical infrastructure into three-dimensional power plants. Recent data shows:
Let's crunch numbers like the Ming accountants did. The Badaling pilot section:
| Metric | Pre-Wincle | Post-Implementation |
|---|---|---|
| Annual CO2 Reduction | 0 tons | 4,200 tons |
| Local Grid Support | Energy Drain | 17% Surplus |
The real magic? They've turned the Wall's thermal mass into a giant battery. Traditional "Hanging Rainbow" drainage systems now circulate phase-change materials that:
Energy experts are buzzing about the "Serpentine Advantage" – how the Wall's winding path creates natural wind acceleration channels. Turbines here outproduce flatland installations by 40%, proving sometimes the best renewable tech was designed 2,300 years ago.
Those iconic watchtowers aren't just photo ops anymore. Each one now houses:
As project lead Dr. Zhang famously quipped during the Mutianyu installation: "We're not just preserving history – we're wiring it into the future's energy matrix." The Great Wall's new battle? Keeping your phone charged while safeguarding the planet's climate stability.

Feed-in tariffs France is aiming to increase its solar PV capacity from 11.5 GW in March 2021 to 23 GW by the end of 2023. The country offers feed-in tariffs for small-scale solar PV up to 100 kWp on rooftops for self-consumption, with a specific grid tariff for collective users and exemption from the domestic tax on electricity for projects under 1 MW. However, a propo. . Solar power in France including overseas territories reached an installed capacity figure of 11.2 GW in 2020, and. . Solar PV installations in France started being substantial only from around 2008. Between 2009 and 2011 PV capacity grew almost tenfold, from a relatively low level.

This graph provides an annual and monthly overview of solar power generation in France. The evolution of solar photovoltaic generation is an important parameter in the energy transition, as it is a renewable and low-carbon energy. In 2022, solar power generation rose sharply on the back of expanded capacity and good sunlight.
The exponential growth of the solar photovoltaic energy sector in France has never stopped since its inception in the early 2000s. In 2022, the PV energy capacity in France amounted to approximately 17 gigawatts, making France the fifth European country for cumulative PV capacity that year.
Solar now significantly contributes to France’s electricity mix, with an output equivalent to three nuclear reactors in volume. The pace of renewable capacity growth will need to accelerate further if France is to meet the public targets set for 2020-2030.
France's installed electricity generation capacity is mainly made up of nuclear, hydroelectric and fossil-fired power plants, as well as renewable power plants (wind, solar photovoltaic, biomass). French power production continues to change in 2022 and 2023, driven by the growth in renewable energy sources.
As a result of the development of renewable energy in 2023, wind and solar installations represented 14.6% of the French electricity mix. Wind power became the third-largest generator, behind nuclear and hydro power but ahead of gas.
Solar capacity growth, combined with good sunlight conditions, drove solar power output up sharply in 2022 to 18.6 TWh (+31% year-on-year). Solar now significantly contributes to France’s electricity mix, with an output equivalent to three nuclear reactors in volume.
