Overt and hidden subsidies
When all the overt and hidden subsidies are taken into account, nuclear
power is much more expensive than any other source of power.
Five accounts of how costly it is are:
Mirage and oasis: energy choices in an age of global warming (PDF, 1.2 MB, New Economics Foundation, June 2005). According to this report, a kilowatt-hour of electricity from a nuclear generator will cost as much as 8.3 pence (16.3 US cents) once realistic construction and running costs are factored in, compared with about 3 pence (5.9 US cents) claimed by the nuclear industry—and that's without including the cost of managing pollution, insuring against catastrophic accidents, or protecting nuclear power plants and nuclear transports from attack by terrorists (see below).
