  • Solar: 0.775 quads
  • Nuclear: 8.42 quads
  • Hydro: 2.77 quads
  • Wind: 2.35 quads

  • Natural Gas: 28.0 quads
  • Coal: 14.0 quads
  • Biomass: 4.91 quads
  • Petroleum: 36.2 quads

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

  • Residential: 10.7 quads
  • Commercial: 8.99 quads
  • Industrial: 25.2 quads
  • Transportation: 28.1 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: 66.7 quads
  • Energy Services: 31.1 quads
  • All of the numbers in the chart indicate total energy flows or uses.
