on wind power....


(yak note...to go in energy 3...wind section)




http://www.countryguardian.net/
this is a general (rather disorganised) site negative to wind power
but the site remains useful....

contrary to the general negativity of this site i must declare an
interest...i think the windmills are utterly beautiful!

there follows abstracts from one of the many items at that site...
http://www.countryguardian.net/vmason.htm

i am surprised this technology is not more oriented to producing
transportable fuel...eg ethanol or methanol...i speculate of a time
when these wind farms end as transportable fossil fuel producers,
akin to the historic great derrick fields of texas...
it is suggested 20MW wind turbines as high as the Eiffel Tower
may be a reality by 2015

"The situation would become much worse [pah!] if/when wind power is
exploited to produce hydrogen as fuel[i regard the idea of a hydrogen
fuelled future as nonsense in the present state of knowledge, much more
likely is a liquid fuel ####link to
http://www.abelard.org/briefings/fossil_fuel_replacements.htm#delivery_of_power].
Assuming a very optimistic LF [load factor] of 50% for 3MW wind turbines,
a recent study (Oswald and Oswald, 2004) estimated that about 96,000 units
would be required to run all British transport vehicles on hydrogen. These
would occupy a dedicated area greater than that of Wales or,
alternatively, a 10 km strip encircling the entire coastline of the
British Isles."

bring it on!!

denmark is the most advanced nation in wind power development
and manufacture...

"It is true that Denmark has placed itself in a leading position with
regard to the utilisation of wind energy, but until now this has certainly
occurred at great cost to nature and with considerable public subsidy"
(Jyllands Posten, 2004)

Despite windy conditions, only 20-24% (LF, ie load factor) of the
potential annual output of West Danish wind turbines has actually been
achieved over the last five years but this is higher than the 15%
calculated for Germany over the same period. most of this output is in
fact being exported, therefore the reality is the denmark is subsidising
electricity that it then exports.
....
"In contrast, its attempts to assimilate large amounts of wind power into
the domestic system have so far proved disappointing, with little
reduction in carbon emissions because of the need for backup to protect
the integrity of its grid (Sandøe, 2003a). The reality is that despite
West Denmark?s massive carpet of wind turbines, the region?s carbon
emissions have recently been rising (Bruun, 2005). Most of its large
exports of wind power simply displace ?green? hydro electricity produced
in Norway and/or Sweden, helping to replenish reservoirs only in dry
periods or when power is cheap. This led a former Chairman of Eltra to
ask: ["Is it environmentally friendly to produce electricity with wind
turbines if there is no-one who can use it? And is it environmentally
friendly to burn natural gas in decentralised heat and power plants while
dumping the over-production of Danish wind electricity in Norway, where it
possibly leads to water being diverted away from the water turbines?"]
(Kongstad, 2001). Processes involved in the manufacture, excavation and/or
installation of access roads, massive concrete foundations, turbine
components, pylons, and associated equipment also militate against the
emission-saving benefits claimed for mega wind power."
