China Farm Gets Shocking Amount of Power From Cow Poop New York Times
A 250,000-head dairy operation in northeast China plans to open the world's largest cow manure-fed power project in September, according to General Electric Co., the company supplying four biogas turbines to the Liaoning Huishan Cow Farm in Shenyang. For comparison, the largest U.S. dairy farms have 15,000 cattle.
The project deals with a few environmental problems in one swoop. As the dairy industry grows in China, it is generating more smelly and polluting waste. Booming electricity demand brings bigger challenges in transmitting power to rural areas, where many dairy farms already happen to be located.
Not to mention climate change. According to a recent U.N. report, the farm-to-table carbon footprint of the dairy sector accounts for 4 percent of greenhouse gas emissions globally. About half of the emissions from milk are methane.
"There is a huge potential in this," said Michael Wagner, marketing leader with GE Energy. "We are looking around the world to expand."
