similar statement was made about methane i revised using widely considered and purported to be consistent with the idea of making the statements less absolute i recognize weasel wording dilemmas but seriously this accurately portrays the qualitative information without misleading not necessary the debate over global warming is long over the debate was a farce created by the people who wanted to pretend that it didn't exist there is no reason to cater to them it's an insult to honesty and good science if we're talking about this part it is the largest single source of fuel for the generation of electricity world wide as well as one of the largest sources of carbon dioxide emissions which is considered the primary cause of global warming coal is extracted from the ground by coal mining either underground mining or open pit mining surface mining then i don't see a problem with the global warming statement except is considered isn't specific but saying it is one of the largest sources is a weasel approach and sounds uninformed i will try to improve talk contribs amount of coal remaining at the current global total energy consumption of terawatt there is enough coal to provide the entire planet with all of its energy for years this sentence is not supported and ignores the growth in coal consumption trends and is therefore unencyclopedic please support it per wp rs or it will be removed shortly actually the only reason it is there is because someone else had the questionable statement that coal could provide the entire planet with all of its energy for years which was based on the typographical error that has been fixed feel free to remove the source was simple arithmetic of the numbers given support for years goodell jeff big coal houghtom mifflin co boston the preceding unsigned comment was added by august utc page number by country articles are the any articles that break up coal power by country like we have for renewables and nuclear talk contribs largest source of carbon dioxide since when was this true oil and it's bi products exceed by far any other source of energy when it comes to co emmisions someone needs to change that statement preceding unsigned comment added by the article does not say anywhere that coal is the largest source it says it is one of the largest sources coal and oil are so close to each other that it is not easy to definitively say that either is the largest coal is also increasing much faster than oil which is likely to be declining soon if it hasn't already begun to decline question about units the article sometimes measures coal consumption in tonnes metric tons one tonne kg and sometimes in tons which could be either the short ton lb or the long ton lb see the section coal as fuel is this change intentional or simply a typo chemical formula should we add a chemical formula on the page i couldn't find one i'm not quite sure of what it is but i know it has hydrogen and carbon in it for sure reversal trends in the united states would be a good subsection as coal plants have been rejected in kansas and i think washingto
