Funny how they, as the prez, avoid talking about wind power although the
prez is right to speak of fuel cells. At the G-8 last week, it was
Martin who had to add about it to what the prez said about energy. They
are working on it nonetheless but probably keep it quiet to avoid
competition before it is implemented...
(take a real life example, a bit smaller, in the US:
http://www.northernexpress.com/editorial/features.asp?id=1015 - quote:
MACKINAW CITY The two windmills operating in Mackinaw City cost $950,000
each and generate 950 kilowatts (kw) at peak capacity, compared to the
600kw windmill in Traverse City. Smiley estimates that each turbine will
produce 2 million kilowatt hours per year (avg 330 homes at 6000 KWH per
home). My son who is in the domain, tells me the KWH in the US averages
..10 which means they will pay for themselves inside 5 years and hence
theoretically each will produce one free windmills every five year...
Think about it now, actual windmills GE sells are 3.5 MW (See:
http://www.gepower.com/businesses/ge_wind_energy/en/index.htm for more
info) which cost even less by KWH.
Based on the figures of Mackinaw, a GE windmill of 3.5 MW provide for
1215+ houses, and produces ~7,37 million KWH.
Build, say, one thousand of these in the north, it would provide for
1.215 million homes at actual cost, and pay for themselves within less
than five years at actual cost, and thus after that 5 years
theoretically provide virtually free energy forever to these 1.2 million
houses, except of course for minimal maintenance cost of the grid and
the windmills). These, if I recall last for 3-4 decades without major
replacement. So if say, one maintains constant energy prices, this can
be doubled every five years for 40 years. 2^^7= 128 in less than half a
century you get 155.5 million houses hooked for 40 years from an initial
investment of a billion or 2.
Now about hydrogen, I have to compute that, and will, but meanwhile do
you see the potential of renewable energy that they all avoid to talk
about? Even Rolling Stones! Why you think?
Like someone who once sang "like a rolling stone", said, "the answer my
friend is blowing in the wind, the answer is blowing in the wind"...

Wind power though is unreliable, in that it is not constant, so some
sort of backup is required to keep the supply going, but looking at the
Global Dimming scenario it would seem that the cure is the removal of
the industrial age, and of course that famous healer Mr Time.

Yeah right... LOL
Wind power is reliable. We will use 10,000 MegaWatts of it by 2010.
http://www.gepower.com/about/press/en/2005_press/030105.htm
There is not question about it, there is no "one day it will work, the
next it won't", it is 10 GigaWatts of constant energy added to the grid.
The technology has evolved a lot since your grand mother.

My grand mother died over 40 years ago, and you probably did not read
that article where they state it takes more energy to build one of
those towers than it ever produces same with solar cells.
Besides it is finite and there are only a few places where they work
see Denmark they have the most of that type of power.
Geo thermal is probably the best method.
