Wind forecasts one pays for are rather better than the general ones,

accuracy.

Old coal plants can be used as part of an integrated system. They
could not be used were they the only plant, but that is not
something I suggested.



The reason why I know the wind forecasts are not that good is that my
hobby is sailing.

They are frequently out by a factor of 2 on the next day forecast. And
available power is IIRC cube of windspeed.

BTW David is _not_ the chief lunatic. He undertakes rational argument,
and produces data supporting his claims.

He always picks at data from the wind lobby. And it does NOT support his
claims. At a casual glance it *appears* to, but deeper inspection shows
it's talking about something else.

He has still never produced one shred of data showing that in the UK,
massive deployment of windfarms will reduce CO2 emissions, or our
dependency on imported fossil fuel.

Because there is none.

Lots of worthies CLAIM that it will, or assume that it must: But it's
never been investigated and the more evidence of real operational issues
that emerges, the more it seems its a very false assumption indeed.



We don't happen to agree with
him, but that does not make him mad.

He is not able to carry a rational argument or answer a direct question.
so we could say hes a marketing bull****ter or a politician. He sure
ain't an engineer.
