"Economic Performance

The average electricity production cost in 2004 for nuclear energy was 1.68 cents per kilowatt-hour, for coal-fired plants 1.90 cents, for oil 5.39 cents, and for gas 5.87 cents.

Nuclear power plants provide low-cost, predictable power at stable prices and are essential in maintaining the reliability of the U.S. electric power system.

The energy in one uranium fuel pellet--the size of the tip of your little finger--is the equivalent of 17,000 cubic feet of natural gas, 1,780 pounds of coal, or 149 gallons of oil."

has a great overview of energy in food transport

"The US food system uses over 10 quadrillion Btu (10,551 quadrillion Joules) of energy each year, as much as France's total annual energy consumption. Growing food accounts for only one-fifth of this. The other four-fifths is used to move, process, package, sell, and store food after it leaves the farm. Some 28% of energy used in agriculture goes to fertilizer manufacturing, 7% goes to irrigation, and 34% is consumed as diesel and gasoline by farm vehicles used to plant, till, and harvest crops. The rest goes to pesticide production, grain drying, and facility operations. . . ."

but the real question is how to measure energy use by person, dollar
or company.  From the consumer point of view you could
rank each service or product by kilowatt hours per dollar. Or rank
each person by saying depending on your income and age and tax
status you consume this many kilowatt hours.  Or you could
rank each corportaion and government.  How many kilowatt hours
does each of the fortune 500 need to generate 1 dollar of
profits.  Factoring in use of materials gets way too complicated.
But I like how we can view it from an electricty and transport
point of view.
