2007 was the year of passing: a global point of view of the new plants, wind broke the nuclear . Last year there were 20 000 megawatts of installed wind against 1.9 thousand megawatts of energy from the atom. It 's a well-established trend for years and is forecast to become even clearer in the next five years. But not enough. For the first time the wind has also won the race in terms of energy actually produced. The two figures do not coincide because the wind turbines operate throughout the year for a smaller number of hours than the nuclear plant and therefore, the same power, produce less electricity.

"The novelty is that, even taking into account this differential use wind power in 2007 has produced more electricity than nuclear power," says Gianni Silvestrini, Director of the Kyoto Club "And the wind turbines to be built in the period 2008 - 2012, that concludes the first phase of the agreements of the Kyoto Protocol, will produce a quantity of electricity equal to two and a half times that of new nuclear power. If we put in the account also the photovoltaic and solar thermal, we can say that, between 2008 e il 2012, il contributo di queste fonti rinnovabili alla diminuzione delle emissioni serra sarà almeno 4 volte superiore al contributo netto prodotto dalle centrali nucleari costruite nello stesso periodo".
La tendenza è consolidata anche dal risveglio del gigante americano. Il 30 per cento di tutta la potenza elettrica installata durante il 2007 negli Usa viene dal vento e il dipartimento federale dell'energia prevede che entro il 2030 l'eolico raggiunga negli States una quota pari al 20 per cento dell'elettricità creando un'industria che, con l'indotto, darà lavoro a mezzo milione di persone. E' un dato in linea con l'andamento di paesi europei come la Danimarca (21 per cento di elettricità from wind), Spain (12 percent), Portugal (9 percent), Germany (7 percent).
Despite the choices of the Bush administration, which has been promoted with public funds the construction of nuclear plants in the United States energy from the atom is rather strong, albeit at a significant level, for thirty years: the last order for a new power plant since 1978. In April last year have been announced commitments for 38 new nuclear reactors, but it is very likely that the number drops dramatically, as has happened in the past, when you pass the stage of operating accounts: the uncertainties related to cost of disposal waste, at the time construction and the decommissioning of end of life have slowed down the race of the atom.
Pending the fourth generation of nuclear reactors, but still has to overcome considerable theoretical and rocks will not be ready before 2030, official estimates foresee a decrease in the weight of nuclear power in the world. The IEA (International Energy Agency) estimates that in 2030 the share of electricity from the atom will be reduced from the current 16 per cent (6 per cent is from the standpoint of total energy) to 9-12 per cent.
