I don't think those two are comparable. Computing is known to be cheaper over time due to Moore's law, but you can't equate gas/electric/water the same way as there are other factors (population, demand, supply) that weigh in. Hopefully more innovation into alternative electricity (solar) will help with part of it. Another factor is inflation such as employee wages to maintain water supplies could increase the end cost to consumers.
