There are about nine million dairy cows inthe United States, and every day each ofthose cows squirts out about 6.5 gallons ofmilk and poops about 24 gallons of manure.We drink the milk; the manure decomposes.And when it does, some very bad thingshappen. Nitrous oxide and methane float upto the heavens like the souls of road kill.According to the Intergovernmental Panelon Climate Change, "nitrous oxide warmsthe atmosphere 310 times more thancarbon dioxide, methane does so 21 timesmore."Dairy cows actually produce about 280litres of methane per day most of it throughburps. | Crown capital eco managementpoop power Poop power infographic
Dairy farmers use the electricity topower their farms, the solid wasteis used for cow bedding, and theliquid waste can be used asfertilizer. All that helps the farmersbottom line and reducesgreenhouse gas emissions. Itsnot new technology, but likeanything involving environmentalhazards and governmentagencies, there are economic andbureaucratic obstacles toovercome. Especially in the statethat produces the most milk in theU.S. Now you are probablythinking of Wisconsin (1.27 milliondairy cows) but you, my dearcheese-loving friend, aremistaken. California is numberone when it comes to milk with1.8 million dairy cows in the state.Of course, it doesnt have to be this way. Inmany places, all that dung is used to generateelectricity. Machines called digesters useanaerobic digestion to extract the gas frommanure and burn it to power generators. Theybasically work like a giant cow stomach. | Onthis corner: environmental scam watch
• But as a result of regulatory hurdles, pollution issues andinadequate financial incentives, most dairy farmers inCalifornia abandoned their digesters years ago. Now anumber of companies hope to reverse that trend with anew generation of digesters. The state is also doing its part.It has introduced a new permit process that aims to reducethe red tape that plagued past renewable energy projects.If digesters were put in use in all of the California’s dairyfarms, the state’s 1.8 million dairy cows could generate upto 1,971 gigawatt hours of electricity each year—enough tocover about .7% of California’s electricity. By comparison11.6% of California’s electricity was generated by allrenewable energy which includes solar, geothermal, smallhydroelectric and biomass.• http://chirpstory.com/li/78890
