Don't you think that , " countries around the world" , should think of " Solar Energy"? Please vote?

I agree with , solar system is a mercy of God to all human beings , we have to explore this pure energy 

it depends to what do you mean by thinking. Solar energy is intermittent. the solar output greatly reduces in cloudy weather and obviously during night it cannot provide any energy output therefore it cannot serve to cater base load requirements. 

Please Note that ......Is this a Question to be asked by professional Engineer......Applied what 

you want to some specific works in Solar Energy field 

Thank You
