I found the article odd, because it talked a lot about the different dynamics and the emissions of different things, but never netted them out. If you're going to talk about the CO2 emissions of the concrete needed for a wind turbine, the obvious next step would be to net them all out and figure out if building wind turbines is a net reduction in CO2 or not. The author seemed to go out of their way to imply that as long as we use Portland cement, it would not be a net reduction, but they never actually came out and said that. Not quite sure what to make of it. It's like reading an article that talks about electric cars and how high electricity can make them more expensive than you think, but then...never actually calculates their operating cost and compares it to a conventional ICE powertrain.
