  The Introduction in this paper underlines the present general situation for
energy and the environment using the words of the US Secretary of Energy. A
short presentation is made of some major nuclear power plants used to study one
fundamental parameter for neutrino oscillations. The nuclear power status in
some Far East Nations is summarized. The 4th generation of nuclear power
stations, with emphasis on Fast Neutron Reactors, is recollected. The world
consumptions of all forms of energies is recalled, fuel reserves are considered
and the opportunities for a sustainable energy future is discussed. These
considerations are applied to the italian situation, which is rather peculiar,
also due to the many consequencies of the strong Nimby effects in Italy.
