Check out these eye-popping pics of solar and wind energy projects in China.

"China now dominates global production of renewable energy technologies. It makes 80% of the world’s solar cells, 70% of its wind turbines, and 70% of its lithium batteries, at prices no competitor can match."

1. Pic of Solar panels armor a hillside in China’s Anhui province, parting only for an access road. Distant ridges host wind turbines, another fast-growing component of an energy revolution that has helped ease air pollution and halt the growth of China’s carbon emissions.George Steinmetz

2. At the focus of the Shouhang Dunhuang plant’s mirrors, a tower set aglow by the concentrated sunshine holds molten salt at 565°C. The salt generates steam that powers a turbine—and because the molten material holds heat through the night, the plant can run nonstop.

3. The fiberglass halves of a single wind turbine blade take shape in a SANY factory in Shaoshan, China. Among the longest in the world, the finished blades extend 107 meters—the length of a soccer field. Demand is so high the factory runs 24/7.

4. A 90-meter needle threading through town, a turbine blade makes its way to a hilltop in Hunan province. China has installed nearly half of the world’s wind power capacity, and although wind is growing more slowly than solar, it generates more reliable power.
