"There could be more than two offshore wind turbines per mile of UK coastline under plans being set out by ministers.

Business Secretary John Hutton says he wants to open up British seas to allow enough new turbines - up to 7,000 - to power all UK homes by the year 2020. "
how on earth do they claim it will 'power all uk homes'
the claim is utter bollox
Not at all.
What's the percentage of power used by home owners? Assuming 20 million households each generously averaging 0.5kW that equates to an installed capacity
between 1 and 2 kw is usual modern estimate

of 10GW ie the equivalent of 10 power stations.
the uk has over 60 'big power stations'....
this is both over-engineered and allows for down times and
peak demand

Or, working backwards, each turbine would have a generating capacity of around 1.5MW
as another poster says...wind is (generously) assessed at
1/3 of the time active....
ie you'd need 3x the generating capacity to equate to online
facilities like coal and nuclear....
present experience is wind will take up in the 5-10% region

it cannot be switched in when required....
ps, you may be confusing electricity received at the household with
real electricity used which includes that embodied in manufactures
(including housing and much more) attributable to the household

pps
.68kw per *person* usage in the uk

i have a table here
http://www.abelard.org/briefings/replacing_fossil_fuels.htm#fuel_usage_efficiency
rf to last column in table

regards...


I was addressing your point when you complained about the use of the term "every home in Britain". As projected, wind power will provide the equivalent electricity need of every home in Britain. It does not address manufacturing and transport.
