Life Cycle Assessment of Coal-fired Power Production
(d) Excludes the energy of the coal and natural gas to the power plant. (e) Includes the coal and natural gas fed to the power plant since these resources are consumed within the boundaries of the system. Because the energy in the coal is greater than the energy delivered as electricity, the life cycle efficiency is negative.
