Are wind turbines bad for the countryside?

Wind turbines attack! by xkcd

Earlier this week I watched the Four Corners story, Against the Wind, on the alleged health impacts of wind turbines and came away wondering just what the point of the program was. Based on what I saw, my clear impression is there’s no issue here – there’s simply no hard evidence of the supposed health dangers of turbines*. The allegations remind me of the scare-mongering around the dangers of winds turbines to birds, which I’ve discussed before.

But I was horrified (no doubt unintentionally) by the vision of rural landscapes blighted by row upon row of giant white robots stretching along the tops of the hills. An occasional turbine is novel, even an object of beauty, but to my sensibilities a massed army of towers is a scar on the countryside.

I know they’re not being erected in pristine bushland, but the sort of sweeping pastoral panoramas in the regions filmed by Four Corners – with green meadows, stands of trees and occasional rustic buildings – are extraordinarily beautiful. It’s a different aesthetic to natural bushland, but no less valuable for that.

As if we haven’t done enough visual damage by permitting ad hoc development on the urban fringe, now we want to make the country look like Texas’s endless oil derricks. We fight tooth and nail to protect the beauty of streetscapes in the cities (admittedly not always successfully), but the defacing of farming landscapes on a grand scale goes on with hardly a murmur of protest.

It’s true we urgently need to reduce carbon emissions but I don’t think it’s obvious we need to pollute the countryside to achieve that goal. That seems a ludicrous price to pay, effectively substituting one form of environmental damage with another.

Wind isn’t the only option we have to address climate change. Wind just happens to be the cheapest form of renewable power – with subsidy – we currently have available. However that calculation doesn’t account for the long-term damage done to scenic landscapes. Just as historically we’ve done with cars, we’re failing to price the negative externalities.
