It has been indicated that such reserves will be running out in 2300 because of increasing energy demand.
Its use however has already created significant CO2 emission with an increasing trend from 1980 to 2010 as of increased energy demand, it has been indicated
in Fig. 7.
As indicated in Fig. 8, fuel energy are getting develop dramatically.
Therefore, there is a need for renewable energy source to meet increasing demand.
Solar power has got prominent mark of development. As of its promising nature to recovery of energy.
It has been reported that solar PV and concentrating solar panels, and solar heaters have got highest annual growth rate in 2013 compared to other renewable energy sources as indicated in Fig. 9.
Among the solar technologies solar PV got highest growth rate in 2013. Ever recorded since vast development took place in solar cell manufacturing.
