The energy from the sun is plentiful, and China is making notable progress in capturing it.

Images taken from two Earth-observing satellites operated by the U.S. Geological Survey have unveiled a swift development of solar farms in the isolated Kubuqi Desert of China. This ambitious endeavor is part of China’s overarching plan to build a colossal “solar great wall,” aimed at producing enough energy to supply Beijing. While the energy generated won’t directly energize the capital, it is significant to note that Beijing hosts over 22 million residents—more than two and a half times the population of New York City.

The visuals, obtained from the Landsat satellites, depict the impressive expansion of the solar farms from 2017 to 2024. A slider tool permits observers to contrast the transformations over time, with the images covering an expanse of about 10 kilometers (6.2 miles). The solar array continues to grow and is anticipated to span a remarkable 250 miles in length and 3 miles in width by 2030, as per NASA.

Although China’s energy composition still heavily depends on fossil fuels—coal, oil, and gas comprised 87 percent of its energy supply in 2022—the country is evidently emphasizing renewable energy. As of June 2024, China tops the globe in solar farm capacity, operating 386,875 megawatts, which constitutes approximately 51 percent of the world total. In contrast, the United States follows in second place with 79,364 megawatts (11 percent), and India comes in third with 53,114 megawatts (7 percent), based on information from Global Energy Monitor’s *Global Solar Power Tracker*.

Experts underscore the critical role of renewable energy sources such as solar and wind in paving the way for a sustainable energy future. These innovations not only diminish dependence on fossil fuels but have also been proven to reduce energy expenses. While fossil fuels continue to hold sway over energy generation in numerous areas, the economic and environmental advantages of solar energy are irrefutable.

China’s initiatives in the Kubuqi Desert, documented by U.S. satellites, represent a clear indication of the increasing feasibility of solar energy. The magnitude and ambition of this project showcase the nation’s dedication to enhancing its renewable energy capabilities and minimizing its carbon emissions.
