Chinese Factory Turns Environmental Bane into Boon
China is beginning to take advantage of an unusual energy source: cow gas. Cows emit a significant amount of methane, a powerful greenhouse gas, when they belch and flatulate. According to People’s Daily, the world’s largest cow-dung methane power plant started operation on January 21 in China’s Inner Mongolia region. With an investment of 45 million RMB (roughly $US5.7 million) from the country’s largest milk producer, Mengniu Dairy, the plant is able to supply 10 million kilowatt-hours of electricity to the national power grid.
