Britain's wind power revolution
Hutton's dramatic policy shift signals less reliance on nuclear energy
Offshore farms could provide all UK homes with electricity within 13
years

Britain is to embark on a wind power revolution that will produce
enough electricity to power every home in the country, ministers will
reveal tomorrow.
The Independent on Sunday has learnt that, in an astonishing U-turn,
the Secretary of State for Business, John Hutton, will announce that
he is opening up the seas around Britain to wind farms in the biggest
ever renewable energy initiative. Only weeks ago he was resisting a
major expansion of renewable sources, on the grounds that it would
interfere with plans to build new nuclear power stations.
The revelation rounds off an unprecedented week in the battle against
global warming in Britain and the United States. On Wednesday and
Thursday measures to boost US use of renewable energy for electricity
and motor fuel and cut greenhouse gas emissions were approved in
Congress. The move comes as 190 nations meet in Bali, Indonesia, to
negotiate what is seen as the world's "last chance" of avoiding the
worst effects of climate change.
Yesterday hundreds of thousands of demonstrators took to the streets
in 86 countries across the globe to demand urgent action from the Bali
meeting. Several thousand campaigners marched in torrential rain
through London to rally at the US embassy. Some posters carried a
picture of President George Bush and the words "Wanted for crimes
against the planet".
Mr Hutton's announcement, which will be made at a conference in Berlin
tomorrow, will identify sites in British waters for enough wind farms
to produce 25 gigawatts (GW) of electricity by 2020, in addition to
the 8GW already planned enough to meet the needs of all the country's
homes.
It means that within only eight years, Britain's offshore wind
industry will be twice the size of that of any other nation in the
world.
The move will put the country well on the way to achieving a tough EU
target of providing 20 per cent of the country's energy from renewable
sources by 2020. But just six weeks ago, Mr Hutton's department, far
from attempting to meet the target was trying to kill it.
In a confidential memorandum, Gordon Brown was advised that the target
was expensive and faced "severe practical difficulties". It went on to
warn how it would reduce "the incentives to invest in other
technologies like nuclear power".
But the Prime Minister overruled Mr Hutton and insisted in his first
green speech as PM last month that the target would be maintained and
met. Now the Business Secretary will also announce tomorrow that he is
to set up a panel under his chairmanship to work out how to hit it.
"By 2020 enough electricity could be generated off our shores to power
the equivalent of all of the UK's homes," Mr Hutton is expected to say
in a speech to the European energy industry in Berlin."The challenge
for Government and for industry is to turn this potential for our
energy and economy into a cost-effective reality. This will be a major
challenge."
The announcement is the first step in implementing the offshore wind
power revolution, which is likely to run into far less environmental
opposition than proposals to build wind farms on land. Once sites have
been identified, companies will then draw their plans and submit them
for approval to Mr Hutton's department and the Department for
Environment, Food and Rural Affairs.
So far two things have held them back: site identification and an
assurance that the resulting installations will be connected to the
national grid. This move removes the former.
Yesterday Maria McCaffery, chief executive of the British Wind Energy
Association, hailed the move as a "decisive step". She added: "We
welcome the Government's effort to place wind energy on a sound
footing and promote Britain into a leader in this sector."

Se solo gli ItaGliani avessero usato il cervello nell'88 a quest'ora
avremmo qualche CIFRA di debito pubblico in meno e potremmo
gradualmente pensare di decommissionare il nucleare per l'energia
eolica.
Inoltre "power every home" non vuol dire poi molto, dato che sul
consumo nazionale la parte "domestica" influisce relativamente poco.
8GW (planned) è una buona cosa ma se poi consideri che te ne serve
almeno 5 volte tanto, che il costo per kW è molto più alto...più che
slogan ci vuole un piano energetico serio e investimenti seri. vedi il

Non riesco a trovare il link di un articolo che dimostrava che
considerando tutti i costi ambientali e di manutenzione un kW da
centrale solare fotovoltaica è molto più "sporco" di uno ricavato da
una centrale a gas a ciclo combinato...l'eolico è il futuro...ma per
Danimarca e Spagna che hanno cosituito società dal nome Vestas o
Gamesa che producono (e fanno fatturato) sulle turbine eoliche!

eolica.
Quoto abbestia. Con tutto il risparmiato sai quanta ricerca e sviluppo
ci facevi!

 Gamesa che producono (e fanno fatturato) sulle turbine eoliche!
Ovvio, noi usiamo  molto il gas ...e tutti sappiamo il perché

 
In effetti anche la Spagna sembra che abbandonerà il nucleare a file del 
ciclo di vita dei sui 8(?) reattori.
Non sono tutti stupidi, in US il nucleare è come il Rock and Roll non si 
fa niente di nuovo dagli anni '70.
Ci deve essere molta propaganda dietro, non è facile discernere cosa è 
politica e cosa è convenienza.
Non vorrei trovarmi a rincorrere tecnologie 'vecchie' e ritrovarmi un 
know how industriale inutile.
Comunque in Italia il risparmio si farà collegando con un ponte Messina 
a Reggio Calabria e per i prossimi anni le risorse saranno investite 
tutte lì.

 Ovvio, noi usiamo  molto il gas ...e tutti sappiamo il perché
Eh sì, chissà a quante mani ha dato il metano...

 
Altre turbine a gas che non vanno maluccio sono le tritacuregge del 
Larderello. Ci sono stati studi anche a Napoli e Roma, ma non si è mosso 
niente.
La percentuale del Geotermico in Toscana non è certo trascutabile e c'è 
l'impegno dell'Enel di portarla al 50% in 10 anni !! Qui c'è ciccia 
gratis, puzza un po' magari, ma costa meno del nucleare e preoccupa meno.
