    Deep shale gas uses the least amount of water

    The Ground Water Protection Council and the U.S. Department of Energy put together water use comparisons between energy resources and, surprisingly, natural gas development from deep shale used the least amount of water for the energy it produced.

    The energy source that required the most amount of water was, unsurprisingly, plant-based biodiesel from soy, requiring a smacking 14,000 to 75,000 gallons of water per MMBtu of energy produced as compared to deep shale natural gas, which needed only 0.60 to 5.80 gallons, 2 gallons of which were estimated for transport of the natural gas.

    One MMBtu, or 1 million British thermal units, a standard measurement for the energy content of fuels, was produced from these energy sources using the following amounts of water:

    Deep shale natural gas 0.60-5.80 gallons

    Nuclear (uranium ready to use in a power plant) 8-14 gallons

    Conventional oil 8-20 gallons

    Synfuel-coal gasification 11-26 gallons

    Coal (ready to use in a power plant) 13-32 gallons

    Oil shale 22-56 gallons

    Tar sands/oil sands 27-68 gallons

    Fuel ethanol from corn 2,510-29,100 gallons

    Biodiesel from soy 14,000-75,000 gallons



    Water facts from the U.S. government





    Although deep shale gas operations produce comparably clean energy and use less water than all the energy sources noted above, the media coverage from this and other water-related issues and shale gas have Americans taking a closer look at water use, supplies and quality.
