You can see that solar collapsed from 8.2GW/a[1] in 2012 to 1.2GW/a in 2015. Wind collapsed from 4.9GW/a in 2017 to 0.9GW/a in 2019. I cannot exactly "proove" which decision was exact killer, but of course any decision takes some time to have the full impact, as larger installations usually are planned years ahead, so any change in politics will take years to take full effect. But the collapse of both wind and solar are difficult to miss - and we rather should have a steady growth in both rates or at least maintain the peak rates on a constant level. At minimum one can blame politics not to have acted to keep up with installations. But there were a lot of decisions taken which were clearly impacting the roll out of renewables. And that with a known deadline for the nuclear power plants. Some decisions taken I can remember: - the feed in tariff was lowered. Even if that is a constant process, when it crosses the threshhold of no longer being profitable, there will be a steep drop in new installations - solar started to recover in recent years, probably because due to the cells becoming cheaper so it began to be more profitable again - as far as I know there was an upper limit for any subsidy, so another reason for a stop of new installations - for wind power the whole system was changed, leading to a deep decline. Subsidies were auctioned off, but unfortunately not including a time limit for actually installing new capacity. So many projects "won" auctions and were never realized. The 5 years alone wouldn't probably not suffice to replace the nuclear power plants, but you have to count in as well all the missed capacity after 2012. If we had just continued at 8GW/a and above, solar capacity would almost be double of what it is today. Pretty much the same with wind. [1] Sorry, might have mistaken the total number on top of the solar bar with the number on the bar. But over 8GW/a is still pretty much it.
