Water gives you more energy rather than soda or coffee because those two drinks depend on caffeine. Caffeine of course gives you energy towards your body, but only for a limited time. Once you have your energy in the morning, you'll become more tired and tired as the day goes on simply because caffeine is like a drug, it creates dependency.
Say you drank two cups of coffee for a few days continuously, one day you suddenly stop, you'll feel really tired that day.
Now if you just drink water, because of water's more benefits towards the body such as digestion, eliminating waste, and the carrying electrolytes, it's basically a given that clean water will give you more energy throughout the day rather than soda or coffee.
