Information like this might not surprise others, but to be totally honest, I have just never thought much about energy until my personal life became linked more closely to it in the last few years. Exhibit A was the look of surprise and disgust my husband gave me when, in a fit of frustration over a nest of tangled cords, I lamented the fact that electricity couldn't be wireless. Anyway, here are some basics:
- The ratio of fossil fuel inputs per unit of food energy produced averages 3:1 for all U.S. agricultural products combined, but runs as high as 35:1 for beef produced in feedlots (including processing and distribution). [Putting Meat on the Table, Johns Hopkins Bloomberg School of Public Health/Pew Charitable Trusts, 2008]
- Global greenhouse gas emissions from all livestock operations account for 18% of all human-produced greenhouse gas emissions, a percentage which is higher than what is produced by the transportation sector. Agriculture accounts for 7.4% of greenhouse gases released in the United States. [Putting Meat on the Table, Johns Hopkins Bloomberg School of Public Health/Pew Charitable Trusts, 2008]
- Coal-fired power plants account for a third of all electricity worldwide. Coal is cheap, and plentiful. But filthy. [Green, Hoffman and Hoffman, 2008]
- While the United States has the highest consumption of barrels of oil as a country, they do not have the highest consumption per capita. [NationMaster.com]
- More than 5% of the U.S. domestic crude oil output in 2010,113 million barrels, was produced in North Dakota [The New Yorker, April 25, 2011]
- The top ten net exporters of oil for 2008 were: Saudi Arabia, Russian Federation, Islamic Republic of Iran, Uniter Arab Emirates, Nigeria, Angola, Norway, Kuwait, Iraq, Venezuela (International Energy Agency, most recent stats available)
- Canada is a producer and a net exporter of electricity. The United States is a producer and a net importer of electricity. (International Energy Agency)
- China's share of global CO2 emissions has quadrupled since 1973 (from over 5% to over 20%), while the North American share of CO2 emissions has dropped by a third, from over 65% to 43%). During that same period of time, global CO2 emissions nearly doubled.
