From page 405...
... Coal power plants typically have generation capacities of about 500 MW; nuclear plants about 1,000 MW (1 GW) ; intermittent sources (e.g., natural gas peaking plants and individual wind turbines)
From page 406...
...  In a 33% efficient power plant, 10,230 Btu of input primary o  energy are required to produce 1 kWh of electricity. Fossil Fuels and Other Liquid Fuels • Coal supply and consumption in the United States is usually expressed in units of metric tons (sometimes written as tonnes and equal to 1,000 kg or 2,200 pounds [lb]
From page 407...
... Waste Streams and Hazardous Air Emissions • Solid and liquid wastes are usually described using familiar units of volume or weight per unit time or quantity of energy produced. (cubic feet per minute [cfm]
From page 408...
... Average annual CO2 emissions in the United States are about 20 tonnes per person. [Note: Sometimes greenhouse gas emissions are reported in terms of tonnes of "carbon." One tonne of carbon emissions equals 3.7 tonnes of CO2 emissions, since the weight of CO2 also includes the weight of the oxygen in the molecule.]
