Benefits
When biogas is used, many advantages arise. In North America, utilization of biogas would generate enough electricity to meet up to three percent of the continent's electricity expenditure. In addition, biogas could potentially help reduce global climate change. Normally, manure that is left to decompose releases two main gases that cause global climate change: nitrogen dioxide and methane. Nitrogen dioxide (NO2) warms the atmosphere 310 times more than carbon dioxide and methane 21 times more than carbon dioxide. By converting cow manure into methane biogas via anaerobic digestion, the millions of cows in the United States would be able to produce one hundred billion kilowatt hours of electricity, enough to power millions of homes across the United States. In fact, one cow can produce enough manure in one day to generate three kilowatt hours of electricity; only 2.4 kilowatt hours of electricity are needed to power a single one hundred watt light bulb for one day. Furthermore, by converting cow manure into methane biogas instead of letting it decompose, global warming gases could be reduced by ninety-nine million metric tons or four percent. In Nepal biogas is being used as a reliable source of rural energy.

Famous quotes containing the word benefits:
“It is with benefits as with injuries in this respect, that we do not so much weigh the accidental good or evil they do us, as that which they were designed to do us.—That is, we consider no part of them so much as their intention.”
—Laurence Sterne (1713–1768)
“It is too late in the century for women who have received the benefits of co-education in schools and colleges, and who bear their full share in the world’s work, not to care who make the laws, who expound and who administer them.”
—J. Ellen Foster (1840–1910)
“When your parents are in political life, you aren’t normal. Everybody talks about the benefits, but I don’t know what the benefits are.... But I’d rather have that kind of mother than an overweight housewife.”
—Katherine Berman Mariano (b. 1957)
