I really think that D is correct here ( although I do see why E is correct as well)....but if in the cities you kept using other traditional sources of energy, then there was no need to harness the power of water, and would explain the discrepancy. Why is that wrong?

Jorge, please read the explanation again. D does not explain why water power was not used. It simply said that because water power was not used, other sources of energy continued to be used -- to which we can say, "well, duh ...".
E on the other hand explains why water power was not used in certain areas even if it was available.
