The fossil fuel burning is the main culprit behind global warming 
which resulted in greenhouse gases (GHG) emissions led by 
carbon dioxide (CO2) emission, key contributor to environmental 
pollution. The rising CO2 emissions intensity and global warming 
complexities have raised the importance to focus on alternative 
energy generation options. The serious concerns over fossil fuel 
consumption, issue of energy security, and GHG emissions 
challenges have brought attention to clean energy sources among 
public and policy analysts as well. Clean energy options (nuclear 
energy and renewable energy) have emerged as alternate energy 
source and effective tools to combat the hazards of climate 
change . As a part of the new energy policy strategy, many 
countries are focusing on increasing the share of nuclear energy 
supply to diversify energy supply, reduce dependence on 
imported fossil fuels with volatile prices, increase energy 
stability and security.
