The key to keep in mind is the environment impact. The fossil fuels are detrimental when something goes wrong and very costly to clean up. Considering the Deepwater Horizon Disaster has reached almost $62 BILLION, plus the loss of the oil and this number is still rising.

That is not factored in. Plus solar is a passive technology and requires limited maintenance on the utility scale and has no upkeep fuel. So the cost are minimal. Now factor in its ease of installation on rooftops and we utilize space that otherwise is ignored.

Overall the bang is quite significant when taken as a whole. The simple fact that as the world transitions to renewables it is an easy phase in and bridge technology.
