The issue of subsidising wind farms is not really a valid argument anyway. Do you think that we don't subsidise current power production?

We do and in a big way. It's just not factored into the cost of the power. Maintenance of ports where coal is shipped in. Upkeep of roads used to transport coal etc to power stations. The massive impact on the health service caused by pollution created by power stations.

If all this was factored into the cost of electricity it would be very expensive. As it is the power companies are heavily subsidised by the tax payer.
