It's expensive to make things cheap. Usually when something becomes cheap quickly it's because demand is high and producing that thing is less expensive. In the case of new energy sources, reaching parity with the grid is very difficult: Not only are technologies like coal already operating at scale, they are also subsidized by the government.

If there was a strong public demand for renewables grid parity wouldn't be that far off. Unfortunately, we're a little too obsessed with other things at the moment, like politicians posting lewd photos online or which television shows to DVR.
