Levelized costs of wind and solar are falling below fossil fuels in several world regions (IRENA).

"So, is the green dream finally coming true?

Unfortunately, not quite. After all these spectacular cost declines, variable renewable energy (VRE) generators still account for only about a quarter of primary energy growth (see the graph below), despite strong policy support. Why is that? Well, although more VRE deployment leads to technological learning, it also brings a host of challenges. These two conflicting forces will shape the VRE story going forward." ...
