Windfail: Individual Wind Facilities Were Less Productive in 2018 than 2017 in Many Regions of the Country

Renewable energy advocates are seemingly always talking about how advances in technology will *finally* make wind and solar competitive with coal, nuclear, and natural gas without taxpayer subsidies. One of their arguments is that wind facilities are becoming more productive over time, generating more of their potential output, but recent data from Lawrence Berkeley Labs shows the productivity of wind turbines fell from 2017 to 2018 in many regions of the country, including Minnesota....

One of those interesting findings is that contrary to the popular narrative that by building wind turbines, we will make Minnesota less dependent upon coal-burning power plants. The graph below shows the annualized capacity factor for each generation source in 2017. I've used this graph in recent blog posts but this merits its own 15 minutes of fame in this post. The capacity factor for coal was 61 percent, much larger than the capacity factor for wind at 35.9 percent,...
