Statement:
The use of non-conventional sources of energy will eliminate the energy crisis in the world.
Conclusions :
I. Modern technology is gradually replacing the conventional sources of energy.
II. The excessive exploitation of environment has led to depletion of conventional sources of energy.

Conclusion I
The statement indicates that an energy crisis can be eliminated by utilising non-conventional sources of energy. Thus, it can be concluded that modern technology is replacing conventional sources as more and more non-conventional sources will be developed with the help of modern technology. 
Thus, Conclusion I follows. 

Conclusion II
The energy crisis mentioned in the statement highlights the excessive environmental exploitation. The preference for non-conventional energy sources over conventional ones indicates a depletion of conventional energy sources. 
Thus, Conclusion II follows.
