Except for nuclear, geothermal and tidal wave generation (and other lesser used energy sources) all energy in planet Earth is solar, accumulated during different time frames.
Sure, solar is great, except current technology is really bad at using it.
Solar has one really great aspect, it can be installed easily at the point of use. Tranporting power on the grid results in a lot of loss, by being at the point of demand solar gets an instant bump in terms of value.
