According
to U.S.
Department of Energy, the United States generated 1,968 billion kilowatt hours of electricity
by burning 900 million metric tons of
coal, which creating 2 billion metric tons of carbon dioxide plus another 360 million
metric tons of coal combustion residues of waste in 2000. See the breakdown
below.

| 1/ Flue Gas Desulfurization
system sprays limestone and water mixture into the exhaust gas of a coal-fired boiler, which
reacts with the SO2 gas to form calcium sulfite or calcium sulfate
slurry. |
By
comparison, an antimatter power plant would use 45 kilograms of antimatter
to generated the 1,968
billion kilowatt hours of electricity. The mass ratio between plants is 25 billion to 1 (2,223 million metric tons/45*2 kilograms).
