Time to phase out the old renewables for new renewables?

When fossil fuels started phasing out solar, wind, water and bio was the natural choice for replacement. Good choice but a drawback with these renewables is that they are based on the rays from the sun. 

With that follows low energy density resulting in many square meters of solar collectors and very large diameter wind turbines and large dams for rain water collection and forest areas that compete with other stake holders. 

Other draw-backs are intermittent availability (day / night for the solar cells), periodic availability (good wind / no wind for the wind turbines), un-predictable availability (storm / flooding / draught, etc.).
