Electricity supply Worldwide

There were 437 nuclear power units in operation in the world in 1995.

Area Number of Units Capacity(MW) 1973-1995 generation (million kWh)
 North America  132  115 629  10 646 375
 Western Europe  150  121 303  10 583 426
 Eastern Europe  68  45 467  3 642 474
 Far East  71  56 064  4 122 837
 Rest of the World  16  5 223  318 895
 TOTAL  437  343 686  29 314 007

Nuclear contribution to electricity by country region, 1995

The world's 437 nuclear plants generated 2 331 billion kilowatt-hours in 1995.

On a region-by-region basis for countries which generate nuclear energy, the world's nuclear energy plants supplied the following shares of electricity in 1995.

Fuel displacements by nuclear energy Worldwide

In addition to nuclear energy, the world has traditionally relied principally on coal for baseload generation purposes. Therefore, as indicated below, the majority of the fossil fuels that have been historically displaced by the world's nuclear plants is coal.

During 1995, the world's 437 nuclear energy plants avoided the use of approximately:

706 million tons of coal.

5.5 trillion cubic feet of gas.

620 million barrels of oil.

During 1973-1995, the use of nuclear worldwide avoided the burning of fossil fuels by about:

8.9 billion tons of coal.

56 trillion cubic feet of gas.

10 billion barrels of oil.

Emissions reductions as a result of nuclear Worldwide

The world's nuclear energy plants reduced carbon dioxide emissions by:

482 million metric tons of carbon in 1995

6.1 billion metric tons of carbon since 1973.

Electric utilities in the world would have emitted 32% more carbon dioxide in 1995 without their nuclear generating capacity.

During 1995, the world's 437 nuclear energy plants avoided the discharge of approximately:

15 million tons of sulphur dioxide.

8 million tons of nitrogen oxide.

Over the period 1973-1995, nuclear energy in the world reduced the sulphur dioxide and nitrogen oxide emissions by about:

219 million tons of sulphur dioxide.

98 million tons of nitrogen oxide.

The world's electric utility sulphur dioxide and nitrogen oxide emissions would have been 35% and 32% greater in 1995, respectively, in the absence of nuclear energy.
