This is great but it does conspicuously leave out one major point of contention with wind power which is their visual impact. Sometimes noise too. Offshore projects have been fought and canceled over this issue. And it looks like the key focus of this article, the 60% capacity, is only achievable if the turbines get even bigger:<p><i>&gt; The average new wind turbine in the US is 80 meters tall at its hub. NREL looks at what capacity factors could be reached with 110 meter tall and 140 meter tall wind turbines.</i><p>Additionally it looks to on-shore sites primarily in the Midwest where it&#x27;s really flat and so these monster turbines could be seen for miles. I would certainly hope people are cool with it considering how green a power source it is, but I thought it was a bit odd that such an in-depth piece left out one of the biggest obstacles to wind power growth.
