Xizang residents using cleaner fuel for heating

LHASA — In Nyanrong, a county with an average altitude of over 4,700 meters in Southwest China's Xizang autonomous region, clean energy projects are transforming winter heating for residents.

The temperature in Nyanrong can still fall below zero toward the end of March, but the home of villager Sangtso was warm.

"No more collecting cow dung for months ahead of winter. Our village's solar-powered heating keeps us cozy," Sangtso said.
