Such hybrid installations were not cost competitive anywhere a year ago but the times they are a changin'. The link below describes one such development.

 I am certainly not claiming that renewable energy will meet all of the world's energy needs.  However, the Lazard reports that I have referenced elsewhere are accurate and are serving to inform investment decisions.
