    We can see that brown coal and coal rate the worst when it comes to energy-related fatalities. Coal-fired power plants are a key source of sulphur dioxide and nitrogen oxides, key precursors to ozone and particulate matter (PM) pollution, which can have an impact on human health, even at low concentrations. 5

  • 10 reasons why coal is a good energy source:

    The prudent us of coal will allow the U. S. the time needed to develop viable alternative energy sources---primarily solar technology and fuel from grain---without any negative impact on our national economy. Coal provides 56% of the electricity used in the nation each day.

  • Energy - Primary and secondary sources - Eniscuola

    Primary and secondary sources. The numerous existing energy sources can be classified in different ways. Primary sources can be used directly, as they appear in the natural environment: coal, oil, natural gas and wood, nuclear fuels (uranium), the sun, the wind, tides, mountain lakes, the rivers (from which hydroelectric energy can be obtained) and the Earth heat that supplies geothermal energy.

  • Radioactive Elements in Coal and Fly Ash, USGS Factsheet ...

    Coal is largely composed of organic matter, but it is the inorganic matter in coal minerals and trace elements that have been cited as possible causes of health, environmental, and technological problems associated with the use of coal. Some trace elements in coal are naturally radioactive.

  • Coal as a Petroleum Source Rock and Reservoir Rock ...

    Coal is defined as a rock composed of more than 50% organic matter by weight and is thus by definition the rock type that is richest in organic matter. For this reason, coal is considered an important petroleum source rock, and the ways in which petroleum compounds can be generated and expelled from coal is a subject of vigorous debate.

  • Our Energy Sources, Coal — The National Academies

    Of all the fossil-fuel sources, coal is the least expensive for its energy content and is a major factor in the cost of electricity in the United States. However, burning coal in electric power plants is a major source of carbon dioxide (CO2) emissions, and its use has other repercussions as well.
