One of the main reasons for building wind farms onshore – rather than offshore – is cost. If the wind farm is constructed in the sea, it can double or triple the cost. Surely – the argument goes – building onshore is a no-brainer because it will keep electricity costs down.
But that argument is flawed because it considers only the construction cost, not the cost to consumers. Building offshore does not triple our electricity bills. The only question that matters is: how much do our bills actually increase?
To answer this question, I’ve calculated how much our electricity bills would increase if Fred Olsen’s industrial-scale wind farm was built offshore rather than – as they plan – across Hope, Kexwith, Holgate, Newsham, and Barningham Moors, which are prominently situated on the Yorkshire Dales skyline.
In practice, it adds only 1–2p per week to our electricity bills. But that needs to be set against the fact we would preserve the natural landscape and character of the Yorkshire Dales. Are we willing to pay 1–2p per week to prevent the industrialisation of the Yorkshire Dales landscape?
A supplementary question is how much would it cost if we built all future wind farms offshore. That is a more complex question, but I address that as well in this blog post.
