  • Natural Gas: 31.0 quads
  • Coal: 13.3 quads
  • Biomass: 5.13 quads
  • Petroleum: 36.9 quads

The pink blocks on the right are end-use sectors (note that electricity is NOT an end-use sector):

  • Residential: 11.7 quads
  • Commercial: 9.45 quads
  • Industrial: 26.3 quads
  • Transportation: 28.3 quads

The grey blocks to the far right indicate whether or not the energy was successfully used ("Energy Services") or wasted ("Rejected Energy").

  • Rejected Energy: 68.5 quads
  • Energy Services: 32.7 quads
  • All of the numbers in the chart indicate total energy flows or uses.
