My late wife traveled to China with some of her family in 1995. China was then in its second decade of rapid industrialization. Coal was the predominate source of electrical power, as evidence by the smog seen in these photos. China was and is the largest consumer of coal. Although it is now making great strides towards renewables, coal is still burned in vast quantities.
