Are there any published figures for how much energy it takes to produce
electricity from a conventional power station?  Obviously they should
include development, finding sources of fuel, drilling/mining, building
pipelines/railway lines, the costs of employing all the people involved,
eventual decommisioning?  Same for nuclear power stations?

Might be an enlightening read.
