Wind farms are stupid. When we need power, the wind doesn't blow. This week is a pretty good example of this phenomenon.
Take a look at this article from the Independent in September, it states that "The 100-turbine Thanet wind farm ... brings the UK's total power from onshore and offshore wind to more than 5GW". I have no reason to dispute this figure but I would contend that it is misleading. Looking at the table below one learns that currently wind farms are producing 141 MW (the table comes from here) which, if the 5GW value is to be believed, is a paltry 2.82% of their maximum ability.
Did I mention that the temperature is low at the moment? That means that we need electricity to help keep us warm. This graph is a good illustration of the amount of electricity we need, as you can see we currently need between 42 GW and 60 GW.
The wind farms are managing to furnish, at best, 0.3% of that requirement.
Pathetic and a waste of our money.
