Because of the intermittency and variability of the wind, conventional power plants must be kept running at full capacity to meet the actual demand for electricity.

This is not a true statment. I can't fight a false statement if that's what you've decided to believe.

From the article: Yet no conventional power plant has been shut down. Because of the intermittency and variability of the wind, conventional power plants must be kept running at full capacity to meet the actual demand for electricity.

Sorry, you're the one who is a believer. You're not dealing with the fact that sometimes (much more often than we'd like) the wind does not turn the turbine because it's not blowing. If they find a way to store the power, then the game changes, but until then, please get off your horse. It doesn't work, it doesn't help. It just makes the wind believers feel good for their imagined superiority and morality.
