Going solar and wind will not make electricity cheaper. It will actually make it more expensive because current technology for solar and wind are still very expensive and the ROI for the install costs takes at least a decade and that does not include the expensive maintenance costs required for such massive installations.

Simply because the power source is free does not mean the resulting electric costs will be cheaper than coal or oil. The reason why coal and oil is cheaper is because coal and oil is a relatively concentrated source of power. For the same reason, electricity from nuclear power is cheaper than solar and wind power.

Note: I am talking about installations big enough to power a few towns, not just a single TV and a couple of LED lights.
