You're only looking at a comparison of spot prices between gas generated electricity and that of wind farms. One needs to take into account fixed costs and operating costs.

That is, if you spend 40 million pounds for a 14 MW turbine it must ultimately earn back that money plus interest over the course of the turbine's life. Much of the calculations of ROI depend on around 20 years of experience. So the data is just coming in and it is not great because wind energy companies are having trouble raising capital and factories are closing.

What that means is the U.K. wind farm industry maybe need bailouts in the future because they can't afford to keep maintaining existing farms at current prices. Not a huge deal.

Just pointing out, your story glosses over these issues. Wind costs may indeed need to be at current high costs or even higher!
