That’s not what I got from the article. (Link for anyone who wants to check it out.)

My interpretation was that decreasing solar/wind electricity prices slows the adoption of renewables, as it becomes increasingly unlikely that you will fully recoup your initial investment over the lifetime of the panel/turbine.

In my mind, this will likely lead to either (a) renewable energy being (nearly) free to use and exclusively state-funded, or (b) state-regulated price fixing of renewable energy.
