Build a water wheel via 3d printing that attaches to the faucet of the sink.
Or just charge your phone and laptop in the library like the rest of the students. If that worried of the 2 cents to charge your phone use a battery bank.
If that concerned. Change lightbulbs to led and don't use high wattage kitchen gadgets.
