Normslly you'd expext that more (and cheaper) supply would drive down prices. Classic market logic.
How do do you explain that this market logic ceases to exist for renewables only? A whopping ~2TW or ~35% of generated power in China is renewable and since renewable energy is roughly 1.5 to 4 times cheaper than e.g. coal per kW/h produced that ought to have some impact.
If it has not I'd be curious in your explaination of the mechanism involved.
