The Lawrence Livermore National Laboratory, under the direction of the U.S. Department of Energy and using data from the Energy Information Administration, has produced flow charts showing the major sources and uses of energy in every U.S. state in the year 2014.
Most coal has some methane (the main component of natural gas) trapped inside it. This methane is produced during the coal formation process and gets trapped on the surface of the coal in tiny pores and fractures.1 Many coalbeds also contain large amounts of water; the pressure from this water keeps the methane in place. Coalbed methane is extracted by pumping out the water, which lowers the pressure, allowing the gas to detach from the coal surface and flow out into the well.1
The Environmental and Energy Study Institute (EESI) held a webinar entitled, "Can Coal Country Thrive in a Clean Energy Economy?" to discuss the range of adaptations, investments, and development programs underway in coal-reliant regions.
The Department of the Interior (DOI) released a notice of intent (NOI) that the Bureau of Land Management (BLM) will prepare a Programmatic Environmental Impact Statement (PEIS) to evaluate potential reforms to the federal coal program.
The Iowa Department of Natural Resources's (DNR) interactive map of coal mines in Iowa shows the locations of coal mines and mine entrances throughout Iowa, and also has the option to search the map by street address. Users may click on the map to access information about mine use dates, type, mining method, entrance type, and links to original mine maps.

The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years.
Types, or “ranks,” of coal are determined by carbon content. There are four types of coal, ordered from highest to lowest rank below.
The Virginia Department of Mines, Minerals, and Energy's interactive map shows the locations of abandoned coal mines throughout the state of Virginia. The map allows users to explore a range of mine features. These features are important because abandoned mines have many land-related problems such as landslides, stream sedimentation, hazardous structures, dangerous highwalls, subsidence, loss of water, acid mine drainage, and open mine portals.
