‘Bravo China’ is a weekly animated series launched by SD Advocates (SDA) to tell China’s stories in an engaging way.
The first episode features a story of the ‘solar sheep’, showing how Chinese engineers have creatively combined Tibetan sheep grazing with solar farm operations to create an ecological synergy.

Electricity is essential to our daily lives. For over a decade, China has been the world’s largest green power producer, with over 80% of its solar and wind energy generated in the western region.
But sunlight and wind can’t be barreled like petroleum or gas; they aren’t available 24 hours a day. So we need to store the energy in these storage stations.
Storage is only the first step. Transmitting electricity thousands of kilometers from the northwest to the southeast with ordinary high voltage wires, would mean losing most of the power during the process.
40 years ago, China started developing ultra high voltage (UHV) transmission, which carries 4 to 6 times the capacity of conventional lines, with a loss of less than 3%. From Xinjiang to Anhui — 3,293 kilometers, roughly the distance from Hong Kong to Hokkaido — the electricity arrives in just 0.01 seconds.
China is the only country that can master and apply UHV on such a massive scale. Since 2009, we have built 42 projects, with the total length enough to circle the equator.
Today, China has also established the world’s first complete set of UHV AC standards. Our technology and equipment have been exported to South America, the Middle East, and Africa — turning Chinese standards into global standards.
