Measuring energy in food. Food calories are a measure of energy in food. One food calorie is equal to 1,000 calories, or 1 kilocalorie. For example, the energy in a 300-food calorie ice cream cone is about the same as the amount of electricity required to light a 100-watt incandescent light bulb for 3.5 hours.

Jan 29, 2012· In comparisons remember coal is about 25,000,000 BTUs per ton, pellets are about 14,000,000 per ton. If coal is $300 per ton and pellets are $200 per ton then $300 of coal is about $350 of pellets for the same BTUs. This does not take into account the efficiencies of the stove. I burn coal and wood. Coal is easier, my wood if free. KaptJaq

Coal Basics What is coal? Coal is a solid fossil hydrocarbon that represents the storage of solar energy from the past in the form of preserved plant material. The plants during the preservation process have been broken down into organic matter that comprises moisture, ash, volatile matter (gases and liquids given off on heating) and fixed carbon.
Anthracite Coal is very shiny, hard black coal, high carbon content and energy density, repels moisture, for domestic industrial uses, including smokeless fuel; Bituminous Coal is softer and shiny, moisture content is 8 -20%, possible for coking coals, volatile matter from 16% - 40%, can be used for thermal or metallurgical applications; Sub-bituminous Coal is soft and black with energy ...
