Champa, a 44-year-old villager in Namling County, Shigatse City, remembers the days when he used cow dung as fuel. At dawn every day, the villagers set out to look for cow dung, sometimes arguing about cow dung, and now the villagers only burn some cow dung to keep warm in winter.

Little cow dung was even a symbol of wealth at one time. In the past, whoever had more cow dung on the wall meant that whoever had more cows, which also meant that they had money.

Nowadays, with the popularization of electricity, the quantity and quality of electrical appliances have become a new indicator of the wealth of villagers. Entering Songga's house in Gyacha County, Lhoka City, freezer and electric heater are all available. Songga said that when he was a child, the family only bought enough meat for a day or two, too much meat could not be kept fresh. Now beef and mutton are put in the freezer and can be eaten at any time.

Since Tibet’s peaceful liberation 70 years ago, From the extreme shortage of electricity to the acceleration of the establishment of a national clean energy base, from a single mode of production to the integration of hydropower, wind, solar and geothermal power generation, Tibet’s farmers and herdsmen’s production and living conditions have been continuously improved, and the production and living conditions of Tibet’s farmers and herdsmen have been continuously improved. Ways are gradually diversified and cleaner. The ecological environment has also been better protected. "Now there are fewer people picking up cow dung. The cow dung has become fertilizer for the growth of grass and trees. The forest grassland has grown luxuriantly, and the wild animals have increased significantly," Songga said.
