Anthracite Anthracite is coal with the highest carbon content, between 86 and 98 percent, and a heat value of nearly 15,000 BTUs-per-pound. Most frequently associated with home heating, anthracite is a very small segment of the U.S. coal market. There are 7.3 billion tons of anthracite reserves in the United States, found mostly in 11 northeastern counties in Pennsylvania. Bituminous The most plentiful form of coal in the United States, bituminous coal is used primarily to generate electricity and make coke for the steel industry. The fastest growing market for coal, though still a small one, is supplying heat for industrial processes. Bituminous coal has a carbon content ranging from 45 to 86 percent carbon and a heat value of 10,500 to 15,500 BTUs-per-pound. Subbituminous Ranking below bituminous is subbituminous coal with 35-45 percent carbon content and a heat value between 8,300 and 13,000 BTUs-per-pound. Reserves are located mainly in a half-dozen Western states and Alaska. Although its heat value is lower, this coal generally has a lower sulfur content than other types, which makes it attractive for use because it is cleaner burning. Lignite Lignite is a geologically young coal which has the lowest carbon content, 25-35 percent, and a heat value ranging between 4,000 and 8,300 BTUs-per-pound. Sometimes called brown coal, it is mainly used for electric power generation.

People do die in heat waves and global warming is real, but it is not possible to attribute any one extreme weather event to global warming and therefore it is not possible to… say how many have died from this cause and because of global warming. The world currently produces around 30 billion metric tons of carbon dioxide just from burning fossil fuels. In other words, several metric tons for every man, woman and child in the world. No matter how many deaths from heatstroke can be attributed directly to global warming, the number is too small to relate to tons of carbon emissions. In any case, many more deaths have occurred due to floods, hurricanes, tornadoes and other extreme weather events, some of which may have been caused or accentuated by global warming.
MMBTU is an acronym for "Million Metric British Thermal Units." The M's represent the Roman numeral for one thousand. One thousand thousands equal one million, thus MMBTU, not… "Million Metric"
What is the energy equivalent in tons of coal for operating a radio for 4 years when a radio uses the energy equivalent of one twentieths of coal per year?
What is the energy equivalent in tons of coal for operating a radio for 4 years when a radio uses the energy equivalent of one twentieths of coal per year?. First look at the… 1/20 ton then invert the 1/4 to get 4/1 then multiply to get the answer of 1/5.. 1/ 20 * 4/ 1 =1/ 5

30,000,000 BTUs Per Ton. Will vary depending on the grade of coal.
Too many variables to answer- type of coal? Pickup or delivered? Where? Prices may range from $30-$65 per ton.

How long would it take to use up 1000 billion tons of coal if worldwide consumption was 4.5 billion tons per year?
1000 billion / 4.5 billion = 1000/4.5 = 222.22... years.
I think a Google search will help you with this one. Try: horse manure/btu or something like that.
carbon Answer: While coal's fixed carbon content ( not associated with volatile carbon content )is graded for heat production and suitability for metallurgical use. it is al…so graded by its sulfur content to to determine its acidity (this affects stack gas treatment). Coal analysis also include hydrogen, oxygen and nitrogen. Uranium analysis is sometimes included for specific pollution or emission relatd studies. Non-elemental anays includes ash (inorganic) and water content
as peat(90% moisture) is not regarded a rank of coal so lignite is the lowest grade of coal containing moisture as high as 30%.
Those two items are equal in weight. Each weighs exactly 2,000 pounds.
