Wind and solar costs have fallen significantly over the past decade. They are already cheaper than the most optimistic scenarios for 2020. This creates the problem that many statistics are out of date and projects that were too expensive in 2016 can be built profitably now. I wouldn't trust Wikipedia's numbers too much for projects that are commissioned now (and therefore built in 2019/2020).
