some general informaiton on wind turbines

It;s a myth that wind turbines will displace conventional power generation in any base load capacity. Load factors observed around the world in any size rely entirely on conventional power generation for backup during high pressure (low wind speed conditions.)

There will be NIL cost saving of any kind in generation capacity and transmission, and this will only add substantial indiscriminatory costs to end users.

- Wind energy is only able to replace traditional
power stations to a limited extent. Their dependence on the prevailing wind conditions means that wind power has a limited load factor even when technically available. It is not possible to guarantee its use for the continual cover of electricity consumption. Consequently, traditional power stations with capacities equal to 90% of the installed wind power capacity must be permanently online in order to guarantee power supply at all times.

- Wind power feed-in can only be forecast to a limited degree. The transmission system operator must balance out variations between the forecast wind power and the actual feed-in using the short-term use of reserve capacity.

(Europe specific this next one)
- Wind power needs a grid infrastructure. The windy coastal regions are precisely the places where the grids have now reached their capacity limits through wind power. High voltage (HV) grids are increasingly reaching their capacity limit and they can take no further electricity from wind farms.

EON Netz's Wind Report 2004 - is strikingly frank about the difficulties and costs of integrating wind generation into a network.
